android - FCM代币发行

Question

我在应用程序的版本 1 中实现了 UrbanAirship。现在，我在应用程序的版本 2 中扩展了 FirebaseMessagingService。我没有在 onNewToken() 中收到能够将 token 发送到我的服务器的调用。我的样板代码看起来像

AndroidManifest.xml

  <service
        android:name=".services.fcm.PushMessageReceiver"
        android:enabled="true"
        android:exported="true"
        android:stopWithTask="false">
        <intent-filter>
            <action android:name="com.google.firebase.MESSAGING_EVENT" />
        </intent-filter>
    </service>

和接收者

        public class PushMessageReceiver extends FirebaseMessagingService {  ...
            @Override
            public void onMessageReceived(RemoteMessage remoteMessage) {
            ...
            }

            @Override
            public void onNewToken(String s) {
            Log.i(Config.LOGTAG, "######**** new token for fcm called");
                Context ctx =ApplicationCustom.getContext();
                SharedPreferences preferences = ctx.getSharedPreferences(Config.SHARED_PREFERENCES, Context.MODE_PRIVATE);
                preferences.edit().putString(Config.SHARED_PREFS_DEVICE_TOKEN, s).apply();
                Intent intent = new Intent(this, XmppConnectionService.class);
                intent.setAction(XmppConnectionService.ACTION_FCM_TOKEN_REFRESH);
                intent.putExtra("token", s);
                startService(intent);
                pushToServer();
            }

               public static void getToken() {
                Log.i(Config.LOGTAG, "######**** get token for fcm called");

                try {
                    Log.i(Config.LOGTAG, "######**** delete token for fcm called");
                    FirebaseInstanceId.getInstance().deleteInstanceId();
                    FirebaseInstanceId.getInstance().getInstanceId();
                } catch (IOException e) {
                    e.printStackTrace();
                    Log.w(Config.LOGTAG, "######**** delete InstanceId failed", e);
                }

                FirebaseInstanceId.getInstance().getInstanceId().addOnCompleteListener(task
        -> {
                    if (!task.isSuccessful()) {
                        Log.w(Config.LOGTAG, "getInstanceId failed", task.getException());
                        return;
                    }

                    Log.i(Config.LOGTAG, "######**** getInstanceId successful");

                    // Get new Instance ID token
                    String token = task.getResult().getToken();
                    Context ctx = ApplicationCustom.getContext();
                    SharedPreferences preferences = ctx.getSharedPreferences(Config.SHARED_PREFERENCES, Context.MODE_PRIVATE);
                    preferences.edit().putString(Config.SHARED_PREFS_DEVICE_TOKEN, token).apply(); 
            pushToServer();
           }); 
        }

    public void pushToServer(){
        // Logic to push token to a server reading from preferences
    }
}

观察:

1) 永远不会为正在更新的应用程序调用 onNewToken。

2) 新安装获得 token

3) 在我添加对 FirebaseInstanceId.getInstance().deleteInstanceId() 的调用之后OnComplete 也不会被调用。

4) 在真实手机(而非模拟器)上调用 getToken(senderId, "FCM") 总是会导致

java.io.IOException: TOO_MANY_REGISTRATIONS

    at com.google.firebase.iid.zzr.zza(Unknown Source:79)
    at com.google.firebase.iid.zzu.then(Unknown Source:4)
    at com.google.android.gms.tasks.zzd.run(Unknown Source:5)

    at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:641)
    at java.lang.Thread.run(Thread.java:764)

我该如何解决观察 1。是否因为 token 已经交付给 UrbanAirship 而没有调用 onNewToken？Fyi getToken 在服务 onCreate() 方法中被调用。

Answer 1

您可以通过以下方式获得 fcm token :-

FirebaseInstanceId.getInstance().getInstanceId()
                .addOnCompleteListener(new OnCompleteListener<InstanceIdResult>() {
                    @Override
                    public void onComplete(@NonNull Task<InstanceIdResult> task) {
                        if (task.isSuccessful()) {
                            String firebaseToken = task.getResult().getToken();
                        } else {
                            getFirebaseToken();
                        }
                    }
                });
