Answer 1

As said above these methods work only on System apps or framework apps from Android N on words. Still we can code for System app for ServiceManager usage as below using reflection of Android Code

  @SuppressLint("PrivateApi")
    public IMyAudioService getService(Context mContext) {
        IMyAudioService mService = null;
        Method method = null;
        try {
            method = Class.forName("android.os.ServiceManager").getMethod("getService", String.class);
            IBinder binder = (IBinder) method.invoke(null, "YOUR_METHOD_NAME");
            if (binder != null) {
                mService = IMyAudioService .Stub.asInterface(binder);
            }
        } catch (NoSuchMethodException | ClassNotFoundException | IllegalAccessException | InvocationTargetException e) {
            e.printStackTrace();
        }
        return mService;
    }
