App下架后推送通知
App下架后推送通知
提问于 2017-02-27 11:44:32
我似乎无法收到我发送的FCM推送通知，我从FCM控制台发送的应用程序在android上被杀死，因为在长时间按下概述按钮并滑动要被杀死的应用程序。当应用程序在前台或后台运行时，它工作得非常好。这可能看起来是一个重复的问题，但我已经尝试了其他方法，但我似乎仍然无法理解。
NotificationService.java
public class NotificationService extends FirebaseMessagingService
{
private static final String TAG = "FCM Service";
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
Log.d(TAG, "From: " + remoteMessage.getFrom());
Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody());
sendNotification(remoteMessage.getNotification().getBody());
}
private void sendNotification(String messageBody) {
Intent intent = new Intent(this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent,
PendingIntent.FLAG_ONE_SHOT);
Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
android.support.v4.app.NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle("Firebase")
.setContentText(messageBody)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, notificationBuilder.build());
}
}TokenRefresh.java
public class TokenRefresh extends FirebaseInstanceIdService {
private static final String TAG = "FirebaseIDService";
@Override
public void onTokenRefresh() {
// Get updated InstanceID token.
String refreshedToken = FirebaseInstanceId.getInstance().getToken();
Log.d(TAG, "Refreshed token: " + refreshedToken);
// TODO: Implement this method to send any registration to your app's servers.
sendRegistrationToServer(refreshedToken);
}
/**
* Persist token to third-party servers.
*
* Modify this method to associate the user's FCM InstanceID token with any server-side account
* maintained by your application.
*
* @param token The new token.
*/
private void sendRegistrationToServer(String token) {
// Add custom implementation, as needed.
}
}MainActivity.java
public class MainActivity extends AppCompatActivity {
Context context;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
FirebaseMessaging.getInstance().subscribeToTopic("global");
String token = ("fcm"+ FirebaseInstanceId.getInstance().getToken());
}

你需要标记你的Firebase服务类，以避免与你的主应用程序一起被杀死。
ComponentName componentName = new ComponentName(
applicationContext,
FCMService.class);
applicationContext.getPackageManager().setComponentEnabledSetting(
componentName,
PackageManager.COMPONENT_ENABLED_STATE_ENABLED,
PackageManager.DONT_KILL_APP);Stack Overflow用户

我也有同样的问题。在前台和后台模式下，通知显示得很好，但在应用程序被终止时就不行了。最终我发现了这个：https://github.com/firebase/quickstart-android/issues/41#issuecomment-306066751
问题出在Android Studio的调试模式上。要正确测试您的通知，请执行以下操作:在Android Studio中通过调试运行您的应用程序。把它刷走就会被杀掉。通过手机上的启动器图标重新启动应用程序。再次刷掉它(这样它就会被杀死)。
发送您的通知，现在您将看到它！
希望这解决了你的问题。

尝试向MainActivity.java添加BroadcastReceiver
BroadcastReceiver mRegistrationBroadcastReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
// checking for type intent filter
if (intent.getAction().equals(Config.REGISTRATION_COMPLETE)) {
// gcm successfully registered
// now subscribe to `global` topic to receive app wide notifications
FirebaseMessaging.getInstance().subscribeToTopic(Config.TOPIC_GLOBAL);
displayFirebaseRegId();
} else if (intent.getAction().equals(Config.PUSH_NOTIFICATION)) {
// new push notification is received
String message = intent.getStringExtra("message");
Toast.makeText(getApplicationContext(), "Push notification: " + message, Toast.LENGTH_LONG).show();
txtMessage.setText(message);
}
}
};
displayFirebaseRegId();
}
// Fetches reg id from shared preferences
// and displays on the screen
private void displayFirebaseRegId() {
SharedPreferences pref = getApplicationContext().getSharedPreferences(Config.SHARED_PREF, 0);
String regId = pref.getString("regId", null);
Log.e(TAG, "Firebase reg id: " + regId);
if (!TextUtils.isEmpty(regId))
txtRegId.setText("Firebase Reg Id: " + regId);
else
txtRegId.setText("Firebase Reg Id is not received yet!");
}
@Override
protected void onResume() {
super.onResume();
// register GCM registration complete receiver
LocalBroadcastManager.getInstance(this).registerReceiver(mRegistrationBroadcastReceiver,
new IntentFilter(Config.REGISTRATION_COMPLETE));
// register new push message receiver
// by doing this, the activity will be notified each time a new message arrives
LocalBroadcastManager.getInstance(this).registerReceiver(mRegistrationBroadcastReceiver,
new IntentFilter(Config.PUSH_NOTIFICATION));
// clear the notification area when the app is opened
NotificationUtils.clearNotifications(getApplicationContext());
}
@Override
protected void onPause() {
LocalBroadcastManager.getInstance(this).unregisterReceiver(mRegistrationBroadcastReceiver);
super.onPause();
}
