我正在创建一个包含 FireBase 消息服务的应用程序。
我在 list 中添加了服务:
<service android:name="xxx.xxx.MyFirebaseInstanceIdService">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
</intent-filter>
</service>
<service android:name="xxx.xxx.MyFireBaseMessagingService">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter>
</service>
我有两个用于获取 token 和 firebase 消息的类:
public class MyFirebaseInstanceIdService extends FirebaseInstanceIdService {
@Override
public void onTokenRefresh() {
super.onTokenRefresh();
String recent_token = FirebaseInstanceId.getInstance().getToken();
SharedPreferences sp = getSharedPreferences("mypref", 0);
SharedPreferences.Editor editor = sp.edit();
editor.putString("token", recent_token);
editor.apply();
}
}
和消息类:
public class MyFireBaseMessagingService extends FirebaseMessagingService {
@Override
public void onMessageReceived(final RemoteMessage remoteMessage) {
super.onMessageReceived(remoteMessage);
Intent intent = new Intent(MyFireBaseMessagingService.this, AdvCreateActivity.class);
intent.putExtra("mode","notification");
intent.putExtra("text",remoteMessage.getNotification().getBody());
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(MyFireBaseMessagingService.this,0,intent,PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(MyFireBaseMessagingService.this);
notificationBuilder.setContentTitle(remoteMessage.getNotification().getTitle());
notificationBuilder.setContentText(remoteMessage.getNotification().getBody());
notificationBuilder.setAutoCancel(true);
notificationBuilder.setSmallIcon(R.mipmap.ic_launcher);
notificationBuilder.setContentIntent(pendingIntent);
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0,notificationBuilder.build());
}
}
当应用程序启动时,firebase 服务会自动启动。如果设备没有互联网连接,那么我就无法收到 token 。如果我打开数据或 wifi,firebase 将不会发送 token !
我的问题是:如何在应用程序启动后手动启动 firebase 服务? (我不希望 firebase 服务在启动应用程序时启动!!!)
最佳答案
请在任何您想获取您的 fcm id 的地方调用以下方法。
try {
String refreshedToken = FirebaseInstanceId.getInstance().getToken();
Log.d("Firbase id login", "Refreshed token: " + refreshedToken);
} catch (Exception e) {
e.printStackTrace();
}
