        @Override
        public void onError(Throwable e) {
            Log.d("RECYCLER", "ERROR " + e.getMessage());

        @Override
        public void onComplete() {
            Log.d("RECYCLER", "COMPLETE");
        }
    };

void getAll(mSubscriber);


//and

@Override
public void onDestroy() {
    super.onDestroy();
    mSubscriber.dispose();
    Log.d("RECYCLER","onDestroy");
}
