我目前正在開發一個Android項目。來自服務的運行活動中的調用方法
到目前爲止,我已經實現了火力地堡,特別是FirebaseInstanceIdService和FirebaseMessagingService:
public class FirebaseIDService extends FirebaseInstanceIdService {
private static final String TAG = "FirebaseIDService";
private Context context;
@Override
public void onTokenRefresh() {
context = getApplicationContext();
// Get updated InstanceID token.
String refreshedToken = FirebaseInstanceId.getInstance().getToken();
Log.e(TAG, "Refreshed token: " + refreshedToken);
SharedPreferences sharedPreferences = context.getSharedPreferences("token", context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPreferences.edit();
editor.putString("token", refreshedToken);
editor.commit();
sendRegistrationToServer(refreshedToken);
}
/**
* Persist token to backend.
* @param token The new token.
*/
private void sendRegistrationToServer(String token) {
SendRegistrationKey task = new SendRegistrationKey(context);
task.execute(token);
}
}
public class MessagingService extends FirebaseMessagingService {
private static final String TAG = "MsgService";
/**
* Called when message is received.
*
* @param remoteMessage Object representing the message received from Firebase Cloud Messaging.
*/
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
Log.e(TAG, "From: " + remoteMessage.getFrom());
// Check if message contains a data payload.
if (remoteMessage.getData().size() > 0) {
Log.e(TAG, "Message data payload: " + remoteMessage.getData());
}
// Check if message contains a notification payload.
if (remoteMessage.getNotification() != null) {
Log.e(TAG, "Message Notification Body: " + remoteMessage.getNotification().getBody());
sendNotification(remoteMessage);
}
// Also if you intend on generating your own notifications as a result of a received FCM
// message, here is where that should be initiated. See sendNotification method below.
}
// [END receive_message]
private void sendNotification(RemoteMessage remoteMessage) {
RemoteMessage.Notification notification = remoteMessage.getNotification();
PushNotificationManager PNManager = PushNotificationManager.getInstance(getApplicationContext());
PNManager.buildNotification(notification.getTitle(), notification.getBody());
}
我想實現的是以下幾點:
當應用程序處於後臺時,我只想在通知中心進行簡單的通知。 (這已經在工作)
但是,當應用程序處於前臺並且正在運行時,我想要有不同的行爲: 我想消費推送通知並顯示警報。
但我的問題是:我如何與服務中的正在運行的活動進行交互,或者實現預期行爲的正確方式是什麼?熱爾必須是一個簡單的靈魂,對不對?
在此先感謝
sendBroadcast從服務,並在活動中註冊自廣播接收機在活動
