Android 通知 Firebase 云

Question

我有一个带有 Android Studio 的应用程序和一个 phone 带有 Android 9 的单元格，我也使用 firebase 云消息传递。

发送消息时，到达 phone，但如果应用程序在后台休眠，则 activity 仅打开 MainActivity。

我有那个实现：

implementation 'com.google.firebase:firebase-auth:16.0.5'
    implementation 'com.google.firebase:firebase-messaging:17.5.0'
    implementation 'com.google.firebase:firebase-database:16.0.4'
    implementation 'com.google.firebase:firebase-storage:16.0.4'
    implementation 'com.google.firebase:firebase-firestore:17.1.2'

这是我在 Android

上的 Java 代码

private final String ADMIN_CHANNEL_ID ="admin_channel";

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    NotificationManager notificationManager =
            (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);

    int notificationID = new Random().nextInt(3000);

  /*
    Apps targeting SDK 26 or above (Android O) must implement notification channels and add its notifications
    to at least one of them. Therefore, confirm if version is Oreo or higher, then setup notification channel
  */
  System.out.println("Sdk " + Build.VERSION.SDK_INT);
    Notification.Builder notificationBuilder = null;
    final Intent intent = new Intent(this, DashboardActivity.class);
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK
            | Intent.FLAG_ACTIVITY_CLEAR_TASK );
    PendingIntent pendingIntent = PendingIntent.getActivity(this,
            0, intent,PendingIntent.FLAG_UPDATE_CURRENT);

    Uri notificationSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        //setupChannels(notificationManager);
        CharSequence name = "New notification";
        String description = "Device to devie notification";
        int importance = NotificationManager.IMPORTANCE_HIGH;
        NotificationChannel channel = new NotificationChannel(ADMIN_CHANNEL_ID, name, importance);
        channel.setDescription(description);
        notificationManager.createNotificationChannel(channel);

        notificationBuilder = new Notification.Builder(this, ADMIN_CHANNEL_ID)
                .setSmallIcon(R.drawable.logopqno)
                .setContentTitle(remoteMessage.getData().get("title"))
                .setContentText(remoteMessage.getData().get("message"))
                .setAutoCancel(true)
                .setSound(notificationSoundUri)
                .setOnlyAlertOnce(false)
                .setChannelId(ADMIN_CHANNEL_ID)
                .setContentIntent(pendingIntent);

    } else {
        notificationBuilder = new Notification.Builder(this, ADMIN_CHANNEL_ID)
                .setSmallIcon(R.drawable.logopqno)
                .setContentTitle(remoteMessage.getData().get("title"))
                .setContentText(remoteMessage.getData().get("message"))
                .setAutoCancel(true)
                .setSound(notificationSoundUri)
                .setOnlyAlertOnce(false)
                .setContentIntent(pendingIntent);
    }
    //Set notification color to match your app color template
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP){
        notificationBuilder.setColor(getResources().getColor(R.color.colorPrimaryDark));
    }
    notificationManager.notify(notificationID, notificationBuilder.build());
}

@RequiresApi(api = Build.VERSION_CODES.O)
private void setupChannels(NotificationManager notificationManager){
    CharSequence adminChannelName = "New notification";
    String adminChannelDescription = "Device to devie notification";

    NotificationChannel adminChannel;
    adminChannel = new NotificationChannel(ADMIN_CHANNEL_ID,
            adminChannelName, NotificationManager.IMPORTANCE_HIGH);
    adminChannel.setDescription(adminChannelDescription);
    adminChannel.enableLights(true);
    adminChannel.setLightColor(Color.RED);
    adminChannel.enableVibration(true);
    if (notificationManager != null) {
        notificationManager.createNotificationChannel(adminChannel);
    }
}

Answer 1

在 FCM 中将 Click_action 设置为 activity 您想要打开。

{
"to": "some_device_token",
"content_available": true,
"notification": {
    "title": "hello",
    "body": "yo",
    "click_action": "Notification_activity" // for intent filter in your activity
},

"data": {
    "extra": "juice"
}

在 Manifest.xml

中添加 intent-filter
