how to root android emulator with code examples

As an Android developer, it is very important to have an Android Emulator that allows you to test your applications and make sure they work perfectly before releasing them. However, some developers may need to root the Android Emulator to access the full permission of the Android system, which is not available in a regular Android Emulator.

Rooting the Android Emulator is quite easy and requires only a few steps. In this article, we will discuss how to root the Android Emulator with examples of the specific code that you need.

What is Rooting?

Before we get into rooting the Android Emulator, let's first understand what rooting means for Android. Rooting is the process of obtaining permission to access the Android system on certain devices. In other words, it is the process of unlocking the Android operating system to access its full features and functionality. By doing this, you gain access to the full potential of the Android system and can customize it to your liking.

In simpler terms, rooting is like unlocking the full potential of your smartphone to access the hidden features, improve performance, and install custom Android applications on it. By rooting, you can also get rid of the limitations set by the manufacturer and the carrier, giving you complete control over your device.

Rooting the Android Emulator

Now that you understand what rooting means, let's look at how to root the Android Emulator. Rooting the Android Emulator is a bit different from rooting an actual Android device. In this case, we will be using Android Studio to root the Android Emulator.

Step 1: Create an Android Virtual Device

To root the Android Emulator, you need to create an Android Virtual Device (AVD). If you have already created an AVD, you can skip this step. Otherwise, follow the steps below to create a new AVD:

1. Open Android Studio and click on the "AVD Manager" button in the toolbar.

2. Click on the "Create Virtual Device" button.

3. Select the device you want to emulate and click on the Next button.

4. Select the system image you want to use and click on the Next button.

5. Give your AVD a name and click on the Finish button.

Step 2: Start the Android Emulator

Once you have created your AVD, you need to start the Android Emulator. To do this, follow the steps below:

1. Open Android Studio and click on the "AVD Manager" button in the toolbar.

2. Click on the "Play" button next to the AVD you want to start.

3. Wait for the Android emulator to start.

Step 3: Install Superuser

Now that the Android emulator is running, you need to install Superuser. Superuser is an application that manages those apps that require root access. You can use a pre-built Superuser application or build one from source. Here, for simplicity purposes, we’ll use the pre-built Superuser application.

To install Superuser, follow the steps below:

1. Download the Superuser zip file from the official website.

2. Extract the zip file to a folder.

3. Open the Android Emulator and navigate to the Settings app.

4. Tap on the "Security & Location" option.

5. Enable the "Unknown Sources" option.

6. Open a command prompt (or terminal window) and navigate to the folder where you extracted the Superuser zip file.

7. Run the following command:

adb push Superuser.apk /sdcard/

8. Now, install the Superuser application by running this command:

adb shell pm install -r /sdcard/Superuser.apk

Step 4: Grant Superuser Permissions

Now that Superuser is installed on the Android Emulator, we need to grant it root access to the emulator. To do this, follow the steps below:

1. Open the Android Emulator and launch the Superuser application.

2. Click on the "Grant" button to grant root access to the application.

3. Close the Superuser application.

That's it! You have successfully rooted the Android Emulator. Now, you can have access to the full potential of the Android system.

Code Example

For those who want to try the rooting process programmatically, here are the code examples. Here, we’ll be using Java and the Android Debug Bridge (ADB) to emulate the rooting process:

First, download the Superuser zip file from the official website and extract it to a folder. Create a new Java class and enter the following code:

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class RootEmulator {

public static void main(String[] args) {
Process p;
try {
//the process to execute
p = Runtime.getRuntime().exec("cmd /c adb push Superuser.apk /sdcard/");
p.waitFor();
BufferedReader reader =
new BufferedReader(new InputStreamReader(p.getInputStream()));
String line = reader.readLine();
while (line != null) {
System.out.println(line);
line = reader.readLine();
}
} catch (IOException e) {
e.printStackTrace();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}

This Java code pushes the Superuser apk file into the /sdcard/ directory of the Android Emulator. Next, create another Java class and enter the following code:

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class RootEmulator {

public static void main(String[] args) {
Process p;
try {
//the process to execute
p = Runtime.getRuntime().exec("cmd /c adb shell pm install -r /sdcard/Superuser.apk");
p.waitFor();
BufferedReader reader =
new BufferedReader(new InputStreamReader(p.getInputStream()));
String line = reader.readLine();
while (line != null) {
System.out.println(line);
line = reader.readLine();
}
} catch (IOException e) {
e.printStackTrace();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}

This Java code installs the Superuser.apk file into the Android Emulator by running the command "adb shell pm install -r /sdcard/Superuser.apk". Once Superuser is installed on the Android Emulator, you can grant the root access permissions and start testing your applications with full permissions.

Conclusion

Rooting the Android Emulator is quite easy and straightforward. By following the steps outlined in this article, you can quickly root your Android Emulator and access the full potential of the Android system. As an Android developer, it is essential to have access to the root permissions in the Android Emulator to test your applications thoroughly.

Rooting Android devices and Android emulators has been a subject of debate in the tech industry for years. Some people may argue that there is no need to root your device or emulator, while others may argue the opposite. However, it is important to note that rooting a device or emulator comes with its pros and cons.

Pros of Rooting

1. Increased Control: Rooting your Android device or emulator gives you complete control over the operating system. You can modify or even delete system files and remove bloatware to free up space and improve performance.

2. Access to Advanced Features: Rooting your device or emulator gives you access to advanced features that are not available on a regular device or emulator, such as custom ROMs, kernels, and themes.

3. Better Performance: By removing unwanted apps and optimizing the system, rooted devices and emulators can run more efficiently and faster.

4. More Customization: With root access, you can customize every aspect of your device or emulator, from the UI to the backup-and-restore options.

5. Ad-Blocking: Rooting allows you to install ad-blockers and get rid of intrusive ads that appear on your device or emulator.

Cons of Rooting

1. Security Risks: Rooting your device or emulator can expose it to security risks since it bypasses the security measures put in place by the firmware.

2. Voiding of Warranty: Rooting your Android device or emulator may void the warranty provided by the manufacturer.

3. Risk of Bricking the Device: Rooting is a complex process that can potentially harm your device or emulator if you are not careful. You may end up bricking your device or emulator, making it unusable.

4. Difficulties with Updates: Rooted devices and emulators may face difficulties in receiving regular updates, security patches, and firmware upgrades.

Conclusion

Rooting an Android emulator is a useful technique that developers use to access the full functionality of the Android system. As mentioned above, rooting has both advantages and disadvantages, so it is important to understand the risks before proceeding. If you do decide to root your Android emulator, make sure to follow the steps carefully and take necessary precautions. Overall, rooting can be an effective way to optimize your Android emulator and customize it to suit your needs.
