Broadcast receiver is not registering (working) in Android Pie

Question

Here my code is working till Marshmallow devices but in my Pie devices it is not working.

I read a Google documentation and found remove the receiver tag from manifest and add in activity but I can't understand how to add.

Main problem is when I adding a value in offline mode its stores a value in SQLite but when come in back online mode it does not send SQLite data to server above nogout devices.

Here is my activity:

  broadcastReceiver = new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) {

                readFromLocalStorage();
            }
        };

     buttonAdd.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                SubmitMethode();
//                addPremises();
                relativeLayoutAdd.setVisibility(View.GONE);
                linearLayoutRecycler.setVisibility(View.VISIBLE);
                imageButtonPlus.setVisibility(View.VISIBLE);
            }
        });
    }


    private void SubmitMethode() {
        preName = Objects.requireNonNull(editTextPremises.getText()).toString();
        prewifiName = Objects.requireNonNull(editTextwifiName.getText()).toString();
        prewifiUrl = Objects.requireNonNull(editTextwifiUrl.getText()).toString();
        preserverUrl = Objects.requireNonNull(editTextserverUrl.getText()).toString();
        preImage = getStringImage(bitmap);
        Log.d("responseT",preName + "==" + prewifiName + "==" + prewifiUrl);

        saveToAppServer(preName, prewifiName, prewifiUrl, preserverUrl, preImage);
        editTextPremises.setText("");
        editTextwifiName.setText("");
        editTextwifiUrl.setText("");
        editTextserverUrl.setText("");
        textViewSelect.setText("Select Image");
    }

    private void readFromLocalStorage(){

        sqPremisesList.clear();

        SQLiteDatabase sqLiteDatabase = dbHelper.getReadableDatabase();

        Cursor cursor = dbHelper.readFromLocalDatabase(sqLiteDatabase);
        while (cursor.moveToNext()){

            int sync_status = cursor.getInt(cursor.getColumnIndex(DBContact.SYNC_STATUS));


            sqPremisesList.add(new SqPremises(premisesName, premisesWifiName,
                    premisesWifiUrl, premisesServerUrl, premisesImagePath, sync_status));
        }

                            }

                        }

                    saveToLocalStorage(pName, pWifiName, pWifiUrl, pServerUrl, pImage, DBContact.SYNC_STATUS_FAILED);

        requestQueue.add(jsonObjectRequest);

//            MySingleton.getInstance(PremisesManagementActivity.this).addToRequestQue(jsonObjectRequest);
        }else {
            saveToLocalStorage(pName, pWifiName, pWifiUrl,
                    pServerUrl, pImage, DBContact.SYNC_STATUS_FAILED);

    }
 private void saveToLocalStorage (String pName, String pWifiName, String pWifiUrl,
                                     String pServerUrl,String pImage, int sync){

        DBHelper dbHelper = new DBHelper(this);
        SQLiteDatabase sqLiteDatabase = dbHelper.getWritableDatabase();
        dbHelper.saveToLocalDatabase(pName, pWifiName, pWifiUrl, pServerUrl, pImage,  sync , sqLiteDatabase);
        readFromLocalStorage();
        dbHelper.close();

    }
//
    @RequiresApi(api = Build.VERSION_CODES.O)
    @Override
    protected void onStart() {
        super.onStart();
        registerReceiver(broadcastReceiver, new IntentFilter(DBContact.UI_UPDATE_BROADCAST));

//            IntentFilter filter = new IntentFilter(DBContact.UI_UPDATE_BROADCAST);
//            registerReceiver(broadcastReceiver, filter, Manifest.permission.CHANGE_NETWORK_STATE, null);
//            sendBroadcast();


    }


    @Override
    protected void onPause() {
        super.onPause();
        unregisterReceiver(broadcastReceiver);
    }

And it is receiver which is add on manifest file:

  <receiver android:name=".utils.NetworkMonitor">
            <intent-filter>
                <action android:name="android.net.conn.CONNECTIVITY_CHANGE" />
            </intent-filter>
        </receiver>

And here I am adding my Network monitor file:

if (checkNetworkConnection(context)){
            final DBHelper dbHelper = new DBHelper(context);
            final SQLiteDatabase sqLiteDatabase = dbHelper.getWritableDatabase();

            Cursor cursor = dbHelper.readFromLocalDatabase(sqLiteDatabase);

            while (cursor.moveToNext()){
                int sync_status = cursor.getInt(cursor.getColumnIndex(DBContact.SYNC_STATUS));
                if (sync_status == DBContact.SYNC_STATUS_FAILED){

                    final String premisName = cursor.getString(cursor.getColumnIndex(DBContact.PREMISES_NAME));
                    final String premisWifiName = cursor.getString(cursor.getColumnIndex(DBContact.PREMISES_WIFI_NAME));
                    final String premisWifiUrl = cursor.getString(cursor.getColumnIndex(DBContact.PREMISES_WIFIURL));
                    final String premisServerUrl = cursor.getString(cursor.getColumnIndex(DBContact.PREMISES_SERVERURL));
                    final String premisesImagePath = cursor.getString(cursor.getColumnIndex(DBContact.PREMISES_IMAGEPATH));



                    String Url = Constant.BASE_URL + "addpremises/";

                    HashMap<String, String> params = new HashMap<String, String>();
                    params.put("user", userID );
                    params.put("name", premisName);
                    params.put("wifi_name", premisWifiName);
                    params.put("online_url", premisWifiUrl);
                    params.put("offline_url", premisServerUrl);
                    params.put("image",premisesImagePath);
                    Log.d("responseV", String.valueOf(params));

                    JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Url, new JSONObject(params),
                            new Response.Listener<JSONObject>() {
                                @Override
                                public void onResponse(JSONObject response) {
                                    Log.d("responseJ", String.valueOf(response));

                                    try {
                                        String statusObject = response.getString("status");
                                        String msgObject = response.getString("msg");

                                        if (statusObject.equals("200")) {
                                            dbHelper.updateLocalDatabase(premisName, premisWifiName, premisWifiUrl,
                                                    premisServerUrl, premisesImagePath, DBContact.SYNC_STATUS_OK, sqLiteDatabase);

                                            context.sendBroadcast(new Intent(DBContact.UI_UPDATE_BROADCAST));
                                        }
                                    }catch (JSONException e) {
                                        e.printStackTrace();
                                    }
                                }
                            }, new Response.ErrorListener() {
                        @Override
                        public void onErrorResponse(VolleyError error) {
                            Log.d("responseE", String.valueOf(error.getMessage()));
                        }
                    });
                    requestQueue.add(jsonObjectRequest);
                }
            }


        }

    }

    public boolean checkNetworkConnection(Context context){

        ConnectivityManager connectivityManager =
                (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();
        return (networkInfo != null && networkInfo.isConnected());
    }

How can I solve this problem? I am a beginner to broadcast receiver.

Answer 1

I had the issue related to network call on some project for Android Pie only.

If you are getting issue related to Network call, please add android:usesCleartextTraffic="true" in <application> tag in AndroidManifest.xml file. This might fix your issue for Pie.
