Firebase click_action仅在活动被杀死时执行一次 - Android

Question

我已经实现了有效负载中包含的clickAction Firebase，它将由Android清单的Intent过滤器处理。

在应用程序的前景或后台状态单击通知后，将执行.FcmNotificationTray活动。但是当应用程序被终止或强制关闭时，假设我们仍然在系统托盘上保留通知，则一旦点击该活动将被执行，但是第二次用户选择并单击它将不会执行的通知。

总而言之，当用户第二次选择并打开通知时（状态是应用程序被杀），它将不会执行活动，更可能是clickAction无法控制意图过滤器。

有效载荷：

{
   "notification": {
       "alert": "sample Alert | Green",
       "data": "Timestamp:\n 2016/09/04 13:16:44,
       "sound": "default",
       "gcmNotification": {
           "title": "Sample App,
           "body": "Sample Body | Red",
           "timeToLive": 10,
           "clickAction": "FIREBASE_ACTIVITY"
       }
   },
   "users": [
       "demo@firebase.com"
   ]
}

意图过滤器：

<activity
     android:name=".activities.FcmNotificationTray"
     android:label="TITLE"
     android:theme="@style/AppTheme.NoActionBar">
     <intent-filter>
         <action android:name="FIREBASE_ACTIVITY"/>
         <category android:name="android.intent.category.DEFAULT"/>
     </intent-filter>
</activity>

编辑1： 这是我在用户点击通知后将执行的活动的代码。

public class FcmNotificationTray extends AppCompatActivity {
        AppPreferences mPreferences;
        StringProcessor mStringsplit;
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            onShowPushNotifDialog();
        }
        @Override
        public void onResume(){
            super.onResume();
            onShowPushNotifDialog();
        }
        private void onShowPushNotifDialog(){
            /* Instantiate Preferences */
            mPreferences = new AppPreferences(this);

            /* Get data from notification tray center for the push notification */
            Bundle bundle = getIntent().getExtras();

            /* Call method to split string and set data for shared preference */
            mStringsplit = new StringProcessor();
            mStringsplit.onCreateSplitString(bundle.getString("data"),bundle.getString("alert"),this);

            /* This will be executed if the app is killed or no current activity */
            if (isTaskRoot()) {
                Intent intent = new Intent(this,SplashScreenActivity.class);
                intent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
                intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                startActivity(intent);
            }else{ finish();}
        }
}

编辑2 ：FCM接收器的代码

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {

    // Check if message contains a notification payload.
    if (remoteMessage.getNotification() != null) {

        /* Call Function to show notification */
        showPushNotification(remoteMessage.getData().get("data"),
                remoteMessage.getData().get("alert"));
    }
}

/* For Push Notification */
public void showPushNotification(String data,String alert){
    /* Call method to split string and set data for shared preference */
    mStringsplit = new StringProcessor();
    mStringsplit.onCreateSplitString(data,alert,getApplicationContext());

    /* Get shared Preferences for app in background or foreground */
    mPreference = new AppPreferences(getApplicationContext());
    Boolean actVisibility = mPreference.getVisiblityActivity();

    if(actVisibility) {
        /*  If application is in foreground execute the dialog
         *  The purpose of executing an acitivity is to get the context
         */
        Intent intentdemo = new Intent().setClassName(getPackageName(),getPackageName()
                + mPreference.getClassName());
        intentdemo.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        intentdemo.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP |
                Intent.FLAG_ACTIVITY_SINGLE_TOP);
        intentdemo.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
        startActivity(intentdemo);
    }
