Не удается остановить AppOpsManager от утечки памяти

0 голосов
/ 06 апреля 2020

LeakCanary сообщает AppOpsManager утечка памяти, когда я думаю, что это не должно произойти (на основании OnOpChangedListener перезапуска). Я что-то не так делаю?

Запрос разрешений: 

    AppOpsManager.OnOpChangedListener onOpChangedListener = null;
    AppOpsManager appOpsManager = null;

    public void requestUsagePermissionAndWait(){

        appOpsManager = (AppOpsManager) getContext().getSystemService(Context.APP_OPS_SERVICE);
        onOpChangedListener = new AppOpsManager.OnOpChangedListener(){
            @Override public void onOpChanged(String op, String packageName) {
                    if(appOpsManager != null){
                        appOpsManager.stopWatchingMode(this);

                        if(onOpChangedListener != null){
                            appOpsManager.stopWatchingMode(onOpChangedListener);
                            onOpChangedListener = null;
                        }
                        appOpsManager = null;
                    }
                    ((Activity) getContext()).runOnUiThread(new Runnable() {
                        @Override
                        public void run() {
                            onPermissionGranted();
                        }
                    });

            }
        };
        appOpsManager.startWatchingMode(AppOpsManager.OPSTR_GET_USAGE_STATS, getContext().getPackageName(), onOpChangedListener);
    }
