当应用处于后台/未运行时，未在通知点击时打开特定活动

只有在打开应用程序并执行通知单击时，通知单击才会启动指定的活动。如果应用程序处于后台/未运行且执行了通知单击，则会打开应用程序的MainActivity。简而言之，就像应用程序在活动堆栈之后正常打开而不是在PendingIntent中打开指定的活动。

Firebase实例ID服务：

package com.example.tamzid.pushnotification;

 import android.util.Log;
 import com.google.firebase.iid.FirebaseInstanceId;
 import com.google.firebase.iid.FirebaseInstanceIdService;

 public class MyAndroidFirebaseInstanceIdService extends 
FirebaseInstanceIdService {

private static final String TAG = "MyAndroidFCMIIDService";

@Override
public void onTokenRefresh() {
    //Get hold of the registration token
    String refreshedToken = FirebaseInstanceId.getInstance().getToken();
    //Log the token
    Log.d(TAG, "Refreshed token: " + refreshedToken);
}
private void sendRegistrationToServer(String token) {
    //Implement this method if you want to store the token on your server
}
}

Firebase消息服务：

 package com.example.tamzid.pushnotification;

 import android.app.NotificationManager;
 import android.app.PendingIntent;
 import android.content.Context;
 import android.content.Intent;
 import android.media.RingtoneManager;
 import android.net.Uri;
 import android.support.v4.app.NotificationCompat;
 import android.util.Log;
 import com.google.firebase.messaging.FirebaseMessagingService;
 import com.google.firebase.messaging.RemoteMessage;

 public class MyAndroidFirebaseMsgService extends FirebaseMessagingService     
{
private static final String TAG = "MyAndroidFCMService";
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    //Log data to Log Cat
    Log.d(TAG, "From: " + remoteMessage.getFrom());
    Log.d(TAG, "Notification Message Body: " +     
remoteMessage.getNotification().getBody());
    //create notification
    createNotification(remoteMessage.getNotification().getBody());
}

private void createNotification( String messageBody) {
    Intent intent = new Intent( this , ResultActivity. class );
    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_launcher)
            .setContentTitle("Android Tutorial Point FCM Tutorial")
            .setContentText(messageBody)
            .setAutoCancel( true )
            .setSound(notificationSoundURI)
            .setContentIntent(resultIntent);

    NotificationManager notificationManager =
            (NotificationManager)  
getSystemService(Context.NOTIFICATION_SERVICE);

    notificationManager.notify(0, mNotificationBuilder.build());
 }
}

的AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.tamzid.pushnotification">

<application
    android:name="android.support.multidex.MultiDexApplication"

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity android:name=".ResultActivity"></activity>

            <action android:name="com.google.firebase.INSTANCE_ID_EVENT"

        </intent-filter>
    </service>

</application>

尝试使用remoteMessage.getData()代替remoteMessage.getNotification()

使用remoteMessage.getNotification()：如果邮件包含a   通知负载。

使用remoteMessage.getData()：如果邮件包含   数据有效载荷。

更新onMessageReceived()，如下所示：

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {

    // Check if message contains a data payload.
    if (remoteMessage.getData().size() > 0) 
    {
        //create notification
        createNotification(remoteMessage.getData().toString());
    }
}

点击推送通知时意图进行特定活动。
