Answer 1

First add this to your build.gradle file, this will also allow side by side running of debug and release builds:

buildTypes {
    debug {
        applicationIdSuffix ".debug"
    }
}

Add this method:

public static boolean isDebug(Context context) {
    String pName = context.getPackageName();
    if (pName != null && pName.endsWith(".debug")) {
        return true;
    } else {
        return false;
    }
}

Another option, worth mentioning. If you need to execute some code only when debugger is attached, use this code:

if (Debug.isDebuggerConnected() || Debug.waitingForDebugger()) { 
    //code to be executed 
}

Solved with android:debuggable. It was bug in reading item where in some cases debug flag on item was not being stored in record getting if (m.debug && !App.isDebuggable(getContext())) always evaluated to false. My bad.

The simplest, and best long-term solution, is to use BuildConfig.DEBUG. This is a boolean value that will be true for a debug build, false otherwise:

if (BuildConfig.DEBUG) {
  // do something for a debug build
}
