我使用firebase云消息传递和firebase功能构建了一个聊天应用程序。但是我目前有两个问题。 1.当应用处于打开状态并且收到新消息时,该应用将自动移至该应用的主要活动。 2.其次,我希望仅在后台接收通知。
我该如何实现?
下面是我的onMessageReceived
public class MyFirebaseMessagingService extends FirebaseMessagingService {
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
// Check if message contains a data payload.
if (remoteMessage.getData().size() > 0) {
showNotification(remoteMessage.getData().get("name"), (remoteMessage.getData().get("click_action")), remoteMessage.getData().get("title"));
}
// Check if message contains a notification payload.
if (remoteMessage.getNotification() != null) {
}
}
private void showNotification(String name, String click_action, String title) {
Intent intent;
if (click_action.equals("Download")) {
intent = new Intent(this, Download.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
} else if (click_action.equals("Student_SystemsDevt")) {
intent = new Intent(this, Student_SystemsDevt.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
}
else {
intent = new Intent(this, LoginActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
}
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent, PendingIntent.FLAG_UPDATE_CURRENT);
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setContentTitle(title)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentText(name)
.setAutoCancel(true)
.setStyle(new NotificationCompat.BigTextStyle())
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}
}

答案 0 :(得分:1)
1-实际上,仅当您的应用程序位于enter link description here中时,才会触发onMessageReceived。因此,如果您不覆盖onMessageReceived,则当您的应用程序处于前台状态时,您将不会收到推送
2-根据fcm文档,当您的应用程序在后台运行时,不会触发onMessageReceived
数据有效载荷是根据启动器活动的意图提供的。
它说明了为什么您的推送会重定向到您的主要活动(您的启动器)。
到目前为止,您可以从意图上处理重定向。
您还可以指定要重定向的活动,例如enter link description here:
{
"to":"some_device_token",
"content_available": true,
"notification": {
"title": "hello",
"body": "test message",
"click_action": "OPEN_ACTIVITY_1"
},
"data": {
"extra":"juice"
}
}
不要忘记针对所需活动的意图过滤器:
<intent-filter>
<action android:name="OPEN_ACTIVITY_1" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>

还要在清单中添加“任务”权限。
private boolean isAppForeground() {
ActivityManager activityManager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
List<ActivityManager.RunningAppProcessInfo> appProcesses = activityManager.getRunningAppProcesses();
if (appProcesses == null) {
return false;
}
final String packageName = getPackageName();
for (ActivityManager.RunningAppProcessInfo appProcess : appProcesses) {
if (appProcess.importance == ActivityManager.RunningAppProcessInfo.IMPORTANCE_FOREGROUND && appProcess.processName.equals(packageName)) {
return true;
}
}
return false;
}
if(isAppForeground()){
// Handle notification silently without displaying in notification tray
}else{
// Do your regular stuff
// Check if message contains a data payload.
if (remoteMessage.getData().size() > 0) {
showNotification(remoteMessage.getData().get("name"), (remoteMessage.getData().get("click_action")), remoteMessage.getData().get("title"));
}
// Check if message contains a notification payload.
if (remoteMessage.getNotification() != null) {
}
}
