MyFirebaseInstanceIdService没有调用为什么? [英] MyFirebaseInstanceIdService didn't invoked why?

问题描述

我已经启动MyFirebaseInstanseIdService以获得token，我将直接向您显示代码:

I have initiated MyFirebaseInstanseIdService in order to get token, directly i will show you the code :

    @Override
    public void onTokenRefresh() {
        super.onTokenRefresh();
        String refreshedToken = FirebaseInstanceId.getInstance().getToken();


        storeRegIdInPref(refreshedToken);


        sendRegistrationToServer(refreshedToken);


        Intent registrationComplete = new Intent(Config.REGISTRATION_COMPLETE);
        registrationComplete.putExtra("token", refreshedToken);
        LocalBroadcastManager.getInstance(this).sendBroadcast(registrationComplete);
    }

    private void sendRegistrationToServer(final String token) {
        // sending gcm token to server
        Log.e(TAG, "sendRegistrationToServer: " + token);
    }

    private void storeRegIdInPref(String token) {
        SharedPreferences pref = getApplicationContext().getSharedPreferences(Config.SHARED_PREF, 0);
        SharedPreferences.Editor editor = pref.edit();
        editor.putString("regId", token);
        editor.commit();
    }

我的manifest.xml:

My manifest.xml :

<service android:name=".services.MyFirebaseMessagingService">
        <intent-filter>
            <action android:name="com.google.firebase.MESSAGING_EVENT" />
        </intent-filter>
    </service>

    <service android:name=".services.MyFirebaseInstanceIdService">
        <intent-filter>
            <action android:name="com.google.firebase.INSTANCE_ID_EVENT" />
        </intent-filter>
    </service>

我也尝试通过共享首选项在我的活动中通过broadCast获取令牌，但似乎未调用该类.

I tried to get token via broadCast in my activity also with shared prefrences, but it seems this class didn't invoked.

在我的log中，我看到了以下几行:

In my log i see those lines :

D/FirebaseApp: com.google.firebase.auth.FirebaseAuth is not linked. Skipping initialization.
D/FirebaseApp: com.google.firebase.crash.FirebaseCrash is not linked. Skipping initialization.

还有这个

I/FirebaseInitProvider: FirebaseApp initialization successful

推荐答案

The onTokenRefresh() method only gets called when the current token expires. The current token could expire for the following reasons:

• 应用程序删除实例ID

• App deletes Instance ID

应用已在新设备上还原

用户卸载/重新安装应用

User uninstalls/reinstall the app

用户清除应用数据

在某些情况下，第一次调用getToken()时，它可能会返回一个null值，您应该从该值开始触发onTokenRefresh().

There's also the scenario where the first time you call getToken(), it might return a null value, from where you should expect onTokenRefresh() to trigger.

这样，您应该在初始活动中调用getToken()来生成令牌.

With that, you should call getToken() on your initial activity to generate a token.
