How can we debug a Release APK

SOURCE

In short, add this to the app build.gradle:

android {
    buildTypes {
        release {
            debuggable true
            ...
        }
    }
}

After this, we can just build a relase APK as normal. Run the app -> Attach the debugger -> See log as normal.

Don't use the Manifest method as any field with the Debug enable will be defualt into a debug build instead of a release build.
