广播接收器未在Android Pie中注册（工作） [英] Broadcast receiver is not registering (working) in Android Pie
本文介绍了广播接收器未在Android Pie中注册（工作）的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
在这里，我的代码在棉花糖设备上都可以使用，但是在我的Pie设备上不能使用。
我阅读了一份Google文档，发现从清单中删除了接收者标签，添加活动，但我不知道如何添加。
主要问题是，当我在离线模式下添加值时，它会在SQLite中存储一个值，但是返回时在线模式下，它不会将SQLite数据发送到nogout设备上方的服务器。
这是我的活动：
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）;
}
}）;
}
私人无效的SubmitMethode（）{
preName = Objects.requireNonNull（editTextPremises.getText（））。toString（）;
prewifiName = Objects.requireNonNull（editTextwifiName.getText（））。toString（）;
prewifiUrl = Objects.requireNonNull（editTextwifiUrl.getText（））。toString（）;
reserverUrl = Objects.requireNonNull（editTextserverUrl.getText（））。toString（）;
preImage = getStringImage（bitmap）;
Log.d（ responseT，preName + == + prewifiName + == + prewifiUrl）;
saveToAppServer（preName，prewifiName，prewifiUrl，preserveUrl，preImage）;
editTextPremises.setText（）;
editTextwifiName.setText（）;
editTextwifiUrl.setText（）;
editTextserverUrl.setText（）;
textViewSelect.setText（ Select Image）;
}
private void readFromLocalStorage（）{
sqPremisesList.clear（）;
DBHelper dbHelper =新的DBHelper（this）;
SQLiteDatabase sqLiteDatabase = dbHelper.getReadableDatabase（）;
光标游标= dbHelper.readFromLocalDatabase（sqLiteDatabase）;
while（cursor.moveToNext（））{
String前提名称= cursor.getString（cursor.getColumnIndex（DBContact.PREMISES_NAME））;;

sqPremisesList.add（新的SqPremises（premisesName，pres前提，WifiName，
前提，WifiUrl，前提，ServersUrl，前提，ImagesPath，sync_status））
}

@Override

super.onPause（）;
unregisterReceiver（broadcastReceiver）;

添加到清单文件中的是接收者：
< receiver android：name =。utils.NetworkMonitor>
< intent-filter>
< action android：name = android.net.conn.CONNECTIVITY_CHANGE />
< / intent-filter>
< / receiver>
在这里，我要添加我的网络监视器文件：
if（checkNetworkConnection（context））{
final DBHelper dbHelper = new DBHelper（context）;
最终SQLiteDatabase sqLiteDatabase = dbHelper.getWritableDatabase（）;
光标游标= dbHelper.readFromLocalDatabase（sqLiteDatabase）;
while（cursor.moveToNext（））{
int sync_status = cursor.getInt（cursor.getColumnIndex（DBContact.SYNC_STATUS））;;
if（sync_status == DBContact.SYNC_STATUS_FAILED）{
最终字符串premisName = cursor.getString（cursor.getColumnIndex（DBContact.PREMISES_NAME））;;
最终字符串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前提前提ImagePath = cursor.getString（cursor.getColumnIndex（DBContact.PREMISES_IMAGEPATH））;
字符串网址=常量。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，新的JSONObject（params），
新的Response.Listener< JSONObject>（）{
@Override
public void onResponse（ JSONObject response）{
Log.d（ responseJ，String.valueOf（response））;
try {
String statusObject = response.getString（ status）;
字符串msgObject = response.getString（ msg）;
if（statusObject.equals（ 200））{
dbHelper.updateLocalDatabase（premisName，premisWifiName，premisWifiUrl，
premisServerUrl，前提ImagePath，DBContact.SYNC_STATUS_OK，sqLiteDatabase）；
context.sendBroadcast（new Intent（DBContact.UI_UPDATE_BROADCAST））;
}
} catch（JSONException e）{
e.printStackTrace（）;
}
}
}，新的Response.ErrorListener（）{
@Override
public void onErrorResponse（VolleyError错误）{
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（））;
}
如何解决此问题？我是广播接收器的初学者。
解决方案
我遇到的问题仅与某些用于Android Pie的项目的网络通话有关。 / p>
如果遇到与网络通话相关的问题，请在<$ c中添加 android：usesCleartextTraffic = true AndroidManifest.xml 文件中的$ c>< application> 标记。这可能会解决您的Pie问题。
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();
DBHelper dbHelper = new DBHelper(this);
SQLiteDatabase sqLiteDatabase = dbHelper.getReadableDatabase();
Cursor cursor = dbHelper.readFromLocalDatabase(sqLiteDatabase);
while (cursor.moveToNext()){
String premisesName = cursor.getString(cursor.getColumnIndex(DBContact.PREMISES_NAME));
String premisesWifiName = cursor.getString(cursor.getColumnIndex(DBContact.PREMISES_WIFI_NAME));
String premisesWifiUrl = cursor.getString(cursor.getColumnIndex(DBContact.PREMISES_WIFIURL));
String premisesServerUrl = cursor.getString(cursor.getColumnIndex(DBContact.PREMISES_SERVERURL));
String premisesImagePath = cursor.getString(cursor.getColumnIndex(DBContact.PREMISES_IMAGEPATH));
int sync_status = cursor.getInt(cursor.getColumnIndex(DBContact.SYNC_STATUS));
sqPremisesList.add(new SqPremises(premisesName, premisesWifiName,
premisesWifiUrl, premisesServerUrl, premisesImagePath, sync_status));
}
//
sqPremisesAdapter.notifyDataSetChanged();
cursor.close();
/*TODO: // this is new line code*/
dbHelper.close();
}
private void saveToAppServer(final String pName, final String pWifiName, final String pWifiUrl,
final String pServerUrl, final String pImage){
if (checkNetworkConnection()){
progressDialog.setTitle("Adding....");
progressDialog.setMessage("please wait while we are waiting your premises");
progressDialog.show();
String Url = Constant.BASE_URL + "addpremises/";
HashMap<String, String> params = new HashMap<String, String>();
params.put("user", userID);
params.put("name", preName);
params.put("wifi_name", prewifiName);
params.put("online_url", prewifiUrl);
params.put("offline_url", preserverUrl);
params.put("image", preImage);
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));
progressDialog.dismiss();
try {
String statusObject = response.getString("status");
String msgObject = response.getString("msg");
if (statusObject.equals("200")) {
Toast.makeText(PremisesManagementActivity.this, msgObject, Toast.LENGTH_SHORT).show();
saveToLocalStorage(pName, pWifiName, pWifiUrl, pServerUrl, pImage, DBContact.SYNC_STATUS_OK);
linearLayoutAsk.setVisibility(View.GONE);
relativeLayoutAdd.setVisibility(View.GONE);
imageButtonPlus.setVisibility(View.VISIBLE);
linearLayoutRecycler.setVisibility(View.VISIBLE);
/* String value = "false";
SharedPreferences.Editor editor = sharedPreferences.edit();
editor.putString("value",value);
editor.commit();*/
}else {
Toast.makeText(PremisesManagementActivity.this, msgObject, Toast.LENGTH_SHORT).show();
// linearLayoutAsk.setVisibility(View.VISIBLE);
// imageButtonPlus.setVisibility(View.VISIBLE);
// linearLayoutRecycler.setVisibility(View.GONE);
// relativeLayoutAdd.setVisibility(View.GONE);
saveToLocalStorage(pName, pWifiName, pWifiUrl, pServerUrl, pImage, DBContact.SYNC_STATUS_FAILED);
}
}catch (JSONException e){
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
// error.printStackTrace();
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.
解决方案
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.
