Android: Check if service is running via. bindService

Question

What would be the best way to check if an Android Service is running? I am aware of the ActivityManager API, but it seems like the use of the API is not advised for

Use a shared preference to save service running flag.

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    int res = super.onStartCommand(intent, flags, startId);
    setRunning(true);
    return res;
}

@Override
public void onDestroy() {
    super.onDestroy();
    setRunning(false);
}

private void setRunning(boolean running) {
    SharedPreferences pref = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
    SharedPreferences.Editor editor = pref.edit();

    editor.putBoolean(PREF_IS_RUNNING, running);
    editor.apply();
}

public static boolean isRunning(Context ctx) {
    SharedPreferences pref = PreferenceManager.getDefaultSharedPreferences(ctx.getApplicationContext());
    return pref.getBoolean(PREF_IS_RUNNING, false);
}
