Troubleshooting App Installation Failures in Android 12

As developers, we strive to create user-friendly applications that perform smoothly on all devices. However, with changes introduced in Android 12, you may encounter unexpected hurdles during app installations. One common issue arises when migrating to targetSdkVersion 31, resulting in installation failures due to permission declarations that were acceptable in previous versions.

The Problem

You may receive error messages like the following when attempting to install your app:

This error indicates that your application (or a library it uses) is trying to declare a permission that has been deprecated in Android 12. Specifically, the permission group android.permission-group.HARDWARE_CONTROLS is no longer valid in this SDK version.

Understanding Permissions

The libraries that your application relies upon may still have remnants of older permission declarations, like this example:

The inclusion of android.permission.FLASHLIGHT in the deprecated ANDROID_PERMISSION_GROUP specifically leads to installation crashes.

The Solution

Fortunately, there is a workaround to address this issue. You can explicitly remove the problematic permission from your application’s manifest file.

Steps to Remove the Deprecated Permission

Identify the Permission to Remove: In this scenario, it is the FLASHLIGHT permission.

Edit the Manifest File: You can declare the removal within your manifest file as follows:

Explanation of the Code

tools:node="remove": This directive instructs the build tools to remove the specified permission from your app, even if it's declared in a library.

tools:selector="com.example.lib1": This defines which library the removal applies to, allowing for specificity in your code.

Final Steps

After making these changes:

Rebuild your application to ensure the new configurations apply.

Test the installation on a device running Android 12 to confirm that the installation completes without errors.

Conclusion

Migrating your app to a new SDK version can present challenges, especially regarding permissions and manifest declarations. However, understanding and implementing workarounds like the one outlined above can help ensure that your application is compatible with the latest Android versions.

By addressing deprecated permission groups and removing problematic permissions from your app manifest, you'll pave the way for smoother installations, allowing your users to enjoy your app without interruption.
