我的应用只是在应用程序打开时播放声音（不在后台）。 应用程序收到了消息但未在通知中显示。
当我关闭应用程序或只是让app在后台时，会显示通知。
你能帮助我为什么会这样吗？我想在应用程序打开时显示通知消息 请帮帮我..
这是我的notificationutil.java

这是LoginActivity.java中的方法恢复
@Override
protected void onResume() {
SharedPreferences sharedPreferences = getSharedPreferences(Config.SHARED_PREF, Context.MODE_PRIVATE);
loggin = sharedPreferences.getBoolean(PREFS_LOGGED, false);
if (loggin) {
Intent intent = new Intent(this, MainActivity.class);
startActivity(intent);
finish();
}
LocalBroadcastManager.getInstance(this).registerReceiver(mRegistrationBroadcastReceiver,
new IntentFilter(Config.REGISTRATION_COMPLETE));
LocalBroadcastManager.getInstance(this).registerReceiver(mRegistrationBroadcastReceiver,
new IntentFilter(Config.PUSH_NOTIFICATION));
NotificationUtils.clearNotifications(getApplicationContext());
super.onResume();
}
答案 0 :(得分：0)
我解决了我的问题
更改此代码：
private void handleNotification(String message) {
if (!NotificationUtils.isAppIsInBackground(getApplicationContext())) {
// app is in foreground, broadcast the push message
Intent pushNotification = new Intent(Config.PUSH_NOTIFICATION);
pushNotification.putExtra("message", message);
LocalBroadcastManager.getInstance(this).sendBroadcast(pushNotification);
// play notification sound
NotificationUtils notificationUtils = new NotificationUtils(getApplicationContext());
notificationUtils.playNotificationSound();
}else{
// If the app is in background, firebase itself handles the notification
}
}
有了这个：
private void handleNotification(String message) {
if (!NotificationUtils.isAppIsInBackground(getApplicationContext())) {
// app is in foreground, broadcast the push message
// LocalBroadcastManager.getInstance(this).sendBroadcast(pushNotification);
Intent intent = new Intent( this , MainActivity.class );
intent.putExtra("message", message);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent resultIntent = PendingIntent.getActivity( this , 0, intent,
PendingIntent.FLAG_ONE_SHOT);
Uri notificationSoundURI = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder mNotificationBuilder = new NotificationCompat.Builder( this)
.setSmallIcon(R.mipmap.ic_bpnicon_48)
.setContentTitle("Android Tutorial Point FCM Tutorial")
.setContentText(message)
.setAutoCancel( true )
.setSound(notificationSoundURI)
.setContentIntent(resultIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, mNotificationBuilder.build());
}else{
// If the app is in background, firebase itself handles the notification
Log.e(TAG_DEBUG, "handleNotification: "+"background" );
}
}
