I was amused to see no one have ever asked such a question here before. After a little research in google I found only a few links to root a device in avd. Somewhere I also read that the sdk is already rooted and you just want to install an application which allows other applications to launch as root (am not sure about this).

The reason why I asked this question here in information security is because rooted devices are a must for Penetration testing an android app. So what I am looking for is a step by step tutorial to root a virtual device in my sdk. I have already created a device with android 2.3. Thanks in advance.

In the emulator which you run as part of Android SDK, the adb has root permissions. That is, it can run with UID as 0. Check it with, adb shell id or whoami. If it is not root, run su in the shell which will give you root access. In some custom images like Lineage you can start adb with su permissions by using adb root.

I'm travelling tomorrow and I need to take a basic Linux machine with me. I'd rather just take my tablet than a laptop. So is there a reasonable simple Linux virtual machine that I can install as an Android app. and which I can ssh into with Putty from any PC I find (ideally via the USB cable)?

There is a recent Andronix app which allows running modified distributions without having to root the phone. However, there are many restrictions -started/limitations/ some of which may interfere with the intended usage scenario

In this article, we will look at various techniques being used by the developers and ways to bypass these root detection techniques for android applications. Nowadays many applications such as financial, banking, payment wallet applications do not work on the rooted device. Pentesting requires root permission to install various tools to compromise the security of the application and it is very painful job for any pen tester if app does not work on the rooted device that restricts the tester from performing various test cases.

We would be focusing on the conventional root detection techniques and bypassing those by reverse engineering (Decompiling) APK file and building the new version of modified APK file with root detection evasion, signing techniques for tampered APK and running the APK on a rooted device.

We will be using Android Studio for android virtual device (Emulator), Emulator can be used to install and run apps and test on virtual android device with customized configuration; Android phones, Android tablets, Android Wear, and Android TV devices etc. You can get the latest version of the Android studio from here

Once android studio setup is done, go ahead and create a virtual device with the help of Android Virtual Device (AVD) Manager. Keep the configurations as per your requirements to run APK. As you may aware that AVDs created with the android studio always has root access enabled, apps with root detection logic will not work on these virtual devices.

After you created the virtual device, it can be started from the AVD manager or you can start with command line, no need to go to AVD manager every time. To run the virtual device, open command prompt with the path where SDK was installed and hit the following command illustrated in below screenshot

Further, we would be using android application which is having root detection functionality enabled, its SAMPLE android application developed for the lab analysis, that does not run on the rooted device. Pen testers can use the APK for which they want to bypass the root detection and follow the steps in this article. Once we get the APK file we can install that file in to the emulator by just drag and drop to emulator screen or using adb command as illustrated in the below screenshot

Oops!! Application is throwing error illustrated in above screenshot, from the error we can understand that application has Root Detection Logic implemented. At runtime application is verifying root access and stop running if the device is rooted.

To run this application on the rooted device, first we must understand the Root Detection Logic from the application source code. Once we get better idea about the logic been implemented by the developer for the root access detection, then we can use one of the root detection bypass techniques listed below

So, to begin with, we first need to understand the techniques that developer has implemented to check root access on the device. The most common and well-known techniques being used for root detection in the applications are as follows

Now, we will reverse engineer the application by decompiling the APK file to verify which techniques application is utilizing for root access detection. Here, we will use the dex2jar tool to decompile the APK file and get the java code.

We got the decompiled version of the APK file, i.e., sample_dex2jar.jar file. We will now use JD-GUI tool to read the jar file and understand the root detection logic used in the application.

JD-GUI is a standalone graphical utility that displays Java source codes of ".class" files. You can browse the reconstructed source code with the JD-GUI for instant access to methods and fields. You can get the JD-GUI from here. Using JD-GUI, it is effortless to browse through the java code and search for the strings which we are looking for.

As illustrated in the above screenshot we can see that JD-GUI search has identified two classes ah.class and m.class having string "/system." We will go through both the classes and look at Java code.

Yupp!! As we can see application root detection logic is implemented with these two classes ah.class and m.class, where application at runtime verifying if any root access files and packages are present on the device such as Superuser.apk and su binaries. If application found any of these files on the device, it will stop running and will go into hang state.

Here, we will be using Apktool to decompile the APK, Apktool is a used for reverse engineering 3rd party, closed, binary Android apps. It can decode resources to nearly original form and rebuild them after making some modifications; it makes possible to debug smali code step by step. Read more about Apktool here.

In smali files we can see the file and package names which application is checking to verify the root access, we do not necessarily have to learn the smali programming or code here. What we need to do is just replace the strings with file/package names that are checking for root access, we have highlighted the same in above screenshots.

Once APK is built, we need to sign that APK with public key since Android requires that all APKs be digitally signed with a certificate before they can be installed. We would be using sign.jar file to sign our new APK build.

We are all set now, we are going to uninstall the old APK and install this new signed APK build into the android AVD/Emulator to check if we can run the application on the rooted device and ascertain that we have successfully bypassed root access detection. Illustration below
