Hacking Android APK Tutorial

Tutorial on hacking an Android APK file, which is an android app file, we decompile, hack it, and recompile. Let's go through the setup and basic commands.

I. Introduction to APK format:

Apps in Android have an extension of .apk format - which is basically a special .zip container that is signed with a certificate. The signer could be somebody like Google Apps Store. The idea is that modifying the .apk file means the signature is invalidated, to prevent installation of modified apps.

The main line of defence from installing malicious APK files is to make sure they are downloaded from the Google Apps Store. But once the APK (app) is in the users’ hands, it is unprotected. Most premium apps can be rooted, so ripping apps is easy.

II. Introduction to modifications:

Modifying an APK file is somewhat difficult, depending on the quality of the app. The Dalvik (Android’s virtual machine), prevents code obfuscation - which is the deliberate act of creating hard to understand code. Since the Dalvik supports reflection, and the virtual machine has to be able to interpret the byte code, no obfuscation can ever hope to compete. Note, reflection is the ability of a computer program to examine and modify the structure and behavior - specifically the values, meta-data, properties and functions of an object at runtime. Obfuscation products like ProGuard may become more advanced with time but intense obfuscation will likely have a very negative impact on performance.

ProGuard is a free Java class file shrinker, optimizer, obfuscator, and preverifier. It detects and removes unused classes, fields, methods, and attributes. It optimizes bytecode and removes unused instructions. It renames the remaining classes, fields, and methods using short meaningless names. Finally, it preverifies the processed code for Java 6 or for Java Micro Edition.

III. High level overview:

Suppose I have an APK file
I want to decompile it into something like assembly language
We can do that using the APK Tool, which turns decompiles it into a folder with smali files.
You should know what a smali file is – basically assembly code.
See https://code.google.com/p/smali/
Then we dig through the smali code and make change to get our desired results.
I will cover this lightly. Exactly what to change and how to find it is beyond my scope of knowledge, I only understand basic ideas. Also, there textbooks on how to analyse decompiled code.
We recompile the smali file into APK file
Install and test it on the emulator
Done.

IV. The Setup:

To start playing with your own modifications, you need several tools.

1. Eclipse, to code your own apps (optional again, but the package manager is nice to use):
http://www.eclipse.org/downloads/
2. Java SDK, to do Java development (optional really – but get it anyways):
http://www.oracle.com/technetwork/java/javase/downloads/index.html
3. Android SDK, for the Android emulator:
http://developer.android.com/sdk/index.html
4. APK Tool, to reverse engineer APK files and create smali files:
http://code.google.com/p/android-apktool/
5. Notepad++, a great program that has syntax highlighting addon pack for smali:
http://notepad-plus-plus.org/
6. Addon syntax highlighting for Smali:
http://androidcracking.blogspot.com/2011/02/smali-syntax-highlighting-for-notepad.html
7. Amon_RA’s Testsign tool, for signing the recompiled APK file:
https://sites.google.com/site/chall32/general/testsign.jar

V. The Usage

This will be a walkthrough on how to start your hack.

There’s a nice guide on how to setup everything on the Android SDK website; http://developer.android.com/sdk/installing/index.html

To run the Android emulator, use their Android Virtual Devices Manager. Make a choice in what you want your device to be; just keep in mind the higher the resolution the slower it’ll be. Expect the emulator to run with heavy lag. My manager is located at:

C:\Program Files (x86)\Android\android-sdk\AVD Manager.exe
Open up a terminal, cmd. Most of the tools you require are in the ..\android-sdk\platform-tools folder. Some of them may be in ..\android-sdk\tools

In this terminal, there are some commands you want to be familiar with.

VI. Commands and effects:

a). abd install [..\location\someapp.apk]
Effect: Installs to emulator. Make sure emulator is on!
b). adb uninstall [com.someapp]
Effect: Exactly what to type requires a bit of work, it’s basically the path the android uses. I’ll describe it more later.
c). apktool.bat d someapp.apk dump- someapp
Effect: Decompiles your APK to smali files
d). apktool.bat b dump- someapp someapp-new.apk
Effect: Rebuild the edited smali files
e). java –classpath testsign.jar testsign someapp-new.apk
Effect: Fake sign the file with some certificate, so that when we install, emulator goes “oh ok here’s the signature, and it matches the file, we can proceed”

VII. Digging through the decompiled smali code

I’m going to cover this vaguely, because I am not that familiar with it. Basically you look at the smali files, the xml files, and find interesting stuff that you think is relevant to what you want to do.

Start at a point, such an error message, and work backwords. Say the message “Invalid serial key entered!” – trace that back to where the key gets checked.

When bypassing things like serial key checks, look for check conditions:

If-eq
If-ne
If-nez
If-eqz
Since applications don’t have a console to print to, you could have it print to logs or print as a toast popup message. http://en.wikipedia.org/wiki/Toast_(computing) Also, logs can be viewed with the ..\tools\monitor.bat tool.

When you are digging through smali code, you definitely need to refer to Dalvik opcodes for syntax and usage: http://pallergabor.uw.hu/androidblog/dalvik_opcodes.html

How To Fully BackUp And Restore Your Android Phoane [Complete Tutorial]

Previously, i shared  android tips  like, and some advantages of rooting. Today, In this tutorial, I will guide you through the easiest and most reliable way to fully and 100% back up and restore your Android phone. By fully back up, I don’t mean backing up just your address book or your emails, or your dog. I mean EVERYTHING that resides on your phone with the exception of the SD card – what we will create is essentially a full image of your phone’s current state that you can restore to at any time as if nothing happened. This image will be written to your SD card which you are then free to copy around and back up on your computer. In fact, the backup described here is very similar to imaging your computer hard drive before you swap drives – the principle is the same.

Advantages:

1. You can stop worrying about forgetting to or being unable to back up certain components of your phone, such as text messages – Nandroid backs up everything.
2. You can try out new ROMs, switch between them and the original stock any time by backing up and restoring full images.
3. You will be able to restore to not just your physical phone, but also to any other phone of the same model. Lost your handset and got a replacement? No problem – restore your latest backup and it’s as good as the one you had lost.

Things To Keep In Mind:

• When you restore from a full image backup, you have to restore all or nothing. In other words, you will not be able to get back *just* the photos.
• An obligatory word of warning: there is always that slight chance that something will not work. Nandroid is stable and pretty well tested nowadays but there is a possibility that you won’t be able to restore, so copy the stuff you can’t afford to lose somewhere before starting and make sure you are OK with losing the rest in case something goes wrong. Note that your contacts and the list of applications is already backed up into the cloud by Google, so you don’t need to back them up separately.

Ingredients:
Here is what we will be using. The list may seem overwhelming at first, but don’t fret – every step is really quite simple.
You will need anywhere from 10 minutes to an hour to finish your first backup, depending on your skills.
So here we go. Ready for the big list?
Step 1: Root your phone
Step 2: Install Nandroid Backup.
Aaaand we’re done. That wasn’t so bad, was it?
The above steps and the backup/restore themselves are explained in more detail below.

Step 1 (in details): Root Your Phone:
Rooting is a process of getting full access to all of your phone’s functions. Think of it as unlocking your phone and enabling it to do anything it wants (except for flying – let’s not try that one).
We have a full explanation of the most important benefits that come with rooting your Android phone right here.
You will need root in order to do the full backup as an unrooted phone simply will not grant any application enough access to do it.
Because rooting each phone is different, the easiest way to figure out the right way for your model and Android version would be to just Google “YOUR-PHONE YOUR-ANDROID-VERSION root”.
Step 2 (in details): Install Nandroid Backup:
Nandroid is an application capable of making complete snapshots of your whole phone as well as restoring from those snapshots.
There are different ways of getting Nandroid onto your phone and here we will use the simplest of all approaches – using the ClockworkMod ROM Manager application which also comes with a whole bunch of other useful stuff. It can only be used on rooted phones, which is why step 1 was necessary.
This is the easiest part. Hrm, come to think of it, everything described here is pretty easy but installing an application from the Android Market – what can be easier?

• Access the Android Market by loading the Market app.
• Search for “ROM Manager”.
• Install ClockworkMod ROM Manager.

And now you’re done with step 2. Did I mention this was the last step?
Back Up Your Phone:
Now we can do the actual backup.
The backup itself will take about 5-10 minutes and will produce a new timestamped directory on the SD card. This directory will contain all of the files needed for restoration – they comprise your full backup.
Here, I’ll give you a preview of what a full backup looks like:

How To Fully Back Up And Restore Your Android Phone [Complete Guide]

One-time Setup: Now, before we can back up, we need to install a Recovery Image specific to your phone. Don’t worry – ROM Manager does it for you automatically with only a press of a button.
Important: ”Unplug the USB cable during this step, as some users are reporting problems flashing recovery while plugged in”
This recovery image contains a boot loader which replaces your original boot loader. The boot loader gives you the ability to run Nandroid backup and restore commands outside of the OS. It also lets you install ROMs but we will not do that today. Since the OS cannot back itself up fully while running, ROM Manager will reboot into this boot loader to perform Nandroid operations. Recovery images vary from one phone model to another, and ROM Manager automatically figures out which one you need. These recovery images are not created by one person – there is a large community effort behind them, and the ROM Manager simply brings together in one convenient package. Alright, enough ranting – let’s get to it.
Warning: flashing a recovery image most likely voids your warranty.

• Select Flash ClockworkMod Recovery.
• Confirm your autodetected phone model.
• Wait for it to download.

The one-time setup is complete.

Your First Backup:
If you have successfully installed a recovery image, you’re ready to start your first backup.
This is a 1-click operation.

• Select “Backup Current ROM” and your phone will reboot and start the full backup onto your SD card.
• Just sit back and relax – there is nothing else you need to do.

After the backup is complete, your phone should boot back up normally. You’re done!
The backup is located on your SD card in the clockworkmod/backup/SOMEDATETIME directory. Here is a screenshot of what it contains again:

Feel free to copy these files elsewhere and store them safely.
Restore Your Phone:
You may want to restore the original full backup of your OS that you took in the Back Up step above. Maybe you forgot something in the original installation or want to go back to stock to apply an update your carrier finally published – no problem.
After you’re done restoring, you’ll be back to your original OS as if nothing ever happened (was it just a dream?)
Restoring is just about as easy as backing up:

• Load ROM Manager and select “Manage and Restore Backup”, basically, repeating step 2.
• Select the backup, which includes the OS itself and all the apps, settings – everything that you backed up, from the list.
• Click Restore. You can also rename and delete your backups from this menu.

Look – the phone boots and the resurrection went just fine!
I sincerely hope that this guide was clear and helpful. Of course, if you have any questions or corrections, feel free to share them in the comments.
In conclusion, I’m going to leave you with the screenshots of some other ROM Manager menus as well as the Recovery console:

iOS 7 secrets, tips, tricks and hidden features!

By pavan pardhu

iOS 7 secrets, tips, tricks and hidden features

iOS 7 was introduced with the iPhone 5S and iPhone 5C is now available to download for all iPhone’s and iPads. It is the first major overhaul of the iOS since the original iPhone – And, while lots of the features are similar, how things work has changed significantly in some places, there are lots of new features to get used to as well.
Our iOS 7 tips and tricks guide walks you through some of the new features, how to perform common tasks and some of secret iOS 7 tips and tricks that are harder to find.
How to make text larger and easier to read on iPhone and iPad:- If your eyesight is not so good you don’t necessarily have to switch to a larger phone. That’s because Apple has included a ‘Dynamic Type’ mode that makes text larger in supported apps.
To adjust the setting go to Settings > General > Text Size and adjust the slider as you see fit. Not all apps support it, but they should increase in number as apps are updated to support iOS 7.
How to use keyboard shortcuts for the iPad :- There are some very good keyboards and keyboard cases for the iPad and you can even use an Apple Wireless Keyboard (or any wireless keyboard for that matter) with an iPad for writing longer documents. What’s not so well advertised, however, is that there are a number of useful keyboard shortcuts you can use to get the most from your experience. Here are some of the most useful:
iPad keyboard shortcuts in Safari:

• Command L selects the address bar so you enter a web address or search
• Command W closes the tab you’re looking at
• Command T opens a new tab
• Command R to refresh the current tab
• Command W to close the current tab

Basic text editing shortcuts:

• Command C copies text
• Command X to cut text
• Command V to paste text
• Command Z to undo changes
• Command Shift Z to redo them
• Option Delete will delete the word before the cursor
• Ctrl K deletes the text to the end of the line
• Command Delete deletes the text to the beginning to the line
• Shift and any arrow key to select text

iPad navigation shortcuts:
These aren’t available by default, but can be enabling the Voice Over accessibility feature. To do so, go to Settings > General > Accessibility and then turn it on. Some dedicated iPad keyboards have these shortcuts as dedicated buttons, such as to go back home.

• Ctrl Option H is like pressing the home button
• Ctrl Option H H opens the multitasking window
• Esc acts as a back button
• Option and any arrow key lets you scroll
• Command Shift Tab switches you to the previous app
• Command Tab takes you back again.

How to search your apps, emails, contacts, messages, music and more on iPhone and iPad :- iOS has had universal search, known as Spotlight, for ages and it hasn’t changed much for iOS 7. The only difference is how you access it. In previous versions it had its own ‘screen’ to the left of the main homescreen.

iOS 7 secrets, tips, tricks and hidden features

In iOS 7, Spotlight search is accessed by swiping down on the icon grid on any homescreen – see graphic above. This shows the search box and on-screen keyboard, and it works the same whether you’re using an iPhone or iPad.
By default it searches for a huge range of things: pretty much anything that has a native app. It even searches for podcasts. You can customise what it searches for by going to Settings > General > Spotlight Search and selecting what you want.
How to correct Siri’s pronunciation on iPhone and iPad :- We don’t want to pick on Siri, but it sometimes makes a right hash of pronouncing names. You can fix this just by saying “Siri that’s not how you pronounce that”. It will then ask you to say it again to learn the name better.
How to block messages and calls from people you don’t like on iPhone :- While we’re sure you get on with everyone just fine, sometimes it might be necessary to block certain people from calling you. iOS 7 finally allows this. It’s easy to activate. All you have to do is goto their entry in the Contacts app and scroll down to the ‘Block this contact’ option
How to turn-off parallax wallpapers and movement on iPhone and iPad :- Getting motion sickness, or just don’t like ‘parallax’ effect in iOS 7? No problem, it can be turned off. It’s tucked away in the Accessibility section, so head to Settings > General > Accessibility and find the Reduce Motion option. Done and done.
How to use the LED flash for notifications on iPhone :- The Accessibility section of the Settings app has long been a source of useful tweaks, and it’s still the case in iOS 7. This is an oldie but a goodie. Prefer a light to vibrations? You can make the LED flash… erm… flash when you have notifications. Go to Settings > General > Accessibility and scroll down to ‘Hearing’ where ‘LED Flash for Alerts’ resides.
How to save money by using FaceTime Audio calls :- Those of you lucky enough to have unlimited data plans but limited minutes will like this one. iOS 7 adds the ability to have audio only calls using FaceTime. Just go to the desired contact and press on the phone symbol next to FaceTime. Alternatively, you can search for your contact in the FaceTime app itself.
How to get a quick view of your day on iPhone and iPad :- Apple has revamped the Notification Center for iOS 7 to include what it calls Today View. Today View can show you a number of different things, but by default it shows you the date, a summary of the weather where you are, and the appointments you have on any given day.
Scroll further down and you can see your calendar for the day, up-to-date stocks and shares info and a short summary of your schedule for the next day.
As with Notification Center before, it’s accessed by swiping down from the top edge of the screen and it’s accessible from the lockscreen, homescreen and from within any app.
How to stop people seeing your messages and notifications in iOS 7 The new Notification Center is a nice addition iOS 7, but it does throw up one obvious problem: as it’s accessible from the lock screen, anyone could view your appointments and excerpts of your messages without your pass code.
Luckily Apple has thought of this and it is possible to customise the Notification Center available from the lock screen, or even turn it off entirely.
To do so, go to Settings > Notification Center and under ‘Access on Lock Screen’ disable the features you want to limit or turn off both ‘Today View’ and ‘Notifications View’ to turn off the Notification Center from the lock screen entirely.
How to customise the Today View in iOS 7 You can also customise the Today View to a limited extent, something we hope Apple expands on to allow third-party apps to appear here.

iOS 7 secrets, tips, tricks and hidden features

Head to Settings > Notification Center again and scroll down to the Today View section highlighted above. The options are quite limited at present, but unless you really need it we recommend getting rid of the Stocks updates. Not only do few people genuinely need, it drains battery as it has to be kept up-to-date.
To change the order of what appears, select ‘Edit’ and drag the available items up and down.
How to create your own ‘parallax’ wallpapers for iPhone and iPad There are a few ways to make your wallpaper’s more interesting in iOS 7. One is a dynamic, animated background: a nice idea, albeit one that uses a little extra juice.
More straightforward are the so-called ‘parallax’ wallpapers where the background moves in conjunction with the way you tilt your phone/tablet using the motion sensors. This is the default for all ‘still’ backgrounds, but those not optimised for it can appear a little blurred due to scaling.
To avoid this you can create your own simply by adjusting the resolution of the wallpaper you use. You need to have 200 pixels on each side of the image to create the perfect parallax wallpaper. The correct resolutions are follows:

• iPad 2 and iPad mini: 1,424 x 1,424
• iPad 3, iPad 4 and iPad Air: 2,448 x 2,448
• iPhone 4S: 1,360 x 1,040
• iPhone 5: 1,536 x 1,040

The iPhone 4 doesn’t support parallax wallpapers.
How to switch and close apps on iPhone and iPad One of the more noticeable, and very welcome, changes in iOS 7 is the new way to switch to and close apps running in the background.

iOS 7 secrets, tips, tricks and hidden features

If you own an iPad and have Multitasking Gestures enabled (head to the Settings > General) then you can bring this up by swiping up with four fingers.
How to check your shelves are level using the Compass app The actual Compass app has always been oddity as it’s more useful in actual apps than on its own. But Apple has added somethig a little extra for iOS 7: a spirit level. It’s not the stuff of legend, but it’s bound to come in useful some time, surely?
How to set the default direction type in Apple Maps on iOS 7 Setting aside the merits of Apple’s Maps for the moment, one neat new addition is the ability to set the default directions type: driving or walking. To do so, head to Settings > Maps then scrolls down to the ‘Preferred Directions’ section.
How to enable ‘Do Not Track’ in Safari on iOS 7 The new version of Safari adds support for the, still voluntary, Do Not Track protocol. Websites that respect Do Not Track won’t use cookies and so forth when this is enabled. To do so, go to Settings > Safari and toggle the option under ‘Privacy & Security’
How to quickly toggle Airplane Mode, Wi-Fi, Bluetooth, Brightness and more on iOS 7 This is arguably the most requested feature of iOS 7. It’s taken Apple long enough to act on it, but Control Center in iOS 7 finally delivers. Moreover, all the above features (and more) are accessible from the lock screen.

iOS 7 secrets, tips, tricks and hidden features

Control Center is accessed by swiping up from the bottom edge of the phone, the opposite from the Notifications Center.
Along bottom edge are four icons: Flashlight, Timer, Calculator and Camera. All but the Flashlight one open the respective apps.
Above these are music controls, and above these is quick access to the screen brightness controls.
Finally there’s the five icons at the top starting with Airplane Mode on the left, then Wi-Fi, Bluetooth, Do Not Disturb and Lock Oritentation.
How to toggle Wi-Fi, Bluetooth and open apps using Siri on iOS 7 And if the above isn’t convenient enough, it’s now possible to toggle these settings using Siri. So, for example, “Turn on Wi-Fi” will do exactly that. You can open first and third-party apps well using the obvious command, “Open Facebook app” or similar. “Take a photo” opens the camera app, too.
You can even go deeper into the Settings app, so saying “Open Mail settings” will take you to that section of the Settings app.
It’s worth experiementing with what you can do, or you can tap the ‘?’ symbol in the bottom left of the Siri screen.

How to Increase battery life of your laptop

By pavan pardhu - September, 11th 2013

Every laptop or Netbook user these days have the same headache of limited backup time of batteries. As far as your system is new , you will have a good backup time but when it becomes a few months old you will definitely face problem of limited battery life.

So here I am giving you a solution to Increase battery life of your laptop upto a sufficient extent.

There is an inbuilt command in your computer for improving battery life as well as the performance of the system but not all users are aware of it. Some laptops directly provide an interface with option termed as “ POWER SAVING MODE ” but  if your laptop is old or don’t have this feature by default , you need not to worry because you can do the same task manually.

If you have a laptop with Windows 7 installed, you can use the ‘powercfg‘ command . It will display useful information about your laptop’s energy consumption and usage. If  you can understand and maintain  it correctly then you can extend your Battery life and performance by great amount.

---

Steps Increase battery life of your laptop

---

Step 1: Click on the Start Menu and type “ CMD ” in the Start Search bar.

Step 2: The search will start and it will then display an icon of “ CMD ” . simply right click on it and select Run as administrator.

Step 3: It will open command line, now simply run the command “powercfg -energy” without quotes. (For windows 7 users.)

                                 -OR-

Simply run the command “powercfg /energy” without quotes. (For windows 8 users.)

Step 4: Now Press “Enter”.

Once you successfully execute this command , Windows  will run a complete scan of  your system and it will find some ways to improve performance and power efficiency.

The results of this process will be saved to an HTML file, which is commonly  present  in the “System32” folder of most of the systems.

To access this file, simply follow the path which will be displayed in command prompt window after completion of the command. Read This file to understand that what program in your system is consuming more power and degrading the performance. Fix the Problem to Increase battery life of your laptop.

5 DEADLY LINUX COMMANDS
