Firebase onTokenRefresh() 未被调用 [英] Firebase onTokenRefresh() is not called

问题描述

在我的日志中的 MainActivity 中，我可以看到使用 FirebaseInstanceId.getInstance().getToken() 的令牌并显示生成的令牌.但似乎在我的 MyFirebaseInstanceIDService 延伸到 FirebaseInstanceIdService 的地方，onTokenRefresh() 没有被调用，在这个函数中它被称为令牌最初是在此处生成的.我需要调用 sendRegistrationToServer() 这就是为什么我想知道它为什么不进入 onTokenRefresh() 的原因.

In my MainActivityin my log, I can see the token using FirebaseInstanceId.getInstance().getToken() and it display the generated token. But it seems like in my MyFirebaseInstanceIDService where it is extends to FirebaseInstanceIdService, the onTokenRefresh() is not called, where in this function it was said that the token is initially generated here. I needed to call sendRegistrationToServer() that's why I'm trying to know why it doesn't go in the onTokenRefresh().

这是我的代码

public class MyFirebaseInstanceIDService  extends FirebaseInstanceIdService {


@Override
public void onTokenRefresh() {
    // Get updated InstanceID token.
    String refreshedToken = FirebaseInstanceId.getInstance().getToken();
    Log.d(TAG, "Refreshed token: " + refreshedToken);

        sendRegistrationToServer(refreshedToken);
    }
}

推荐答案

仅在生成新令牌时调用 FirebaseInstanceIdService 中的 onTokenRefresh.如果您的应用之前已安装并生成了令牌，则不会调用 onTokenRefresh.尝试卸载并重新安装应用程序以强制生成新令牌，这将导致 onTokenRefresh 被调用.

onTokenRefresh in FirebaseInstanceIdService is only called when a new token is generated. If your app was previously installed and generated a token then onTokenRefresh would not be called. Try uninstalling and reinstalling the app to force the generation of a new token, this would cause onTokenRefresh to be called.

还要确保您的 FirebaseInstanceIdService 在您的 AndroidManifest.xml 中正确定义

Also be sure that your FirebaseInstanceIdService is properly defined in your AndroidManifest.xml

在您的清单文件中.

 <service
        android:name="com.bnt.etailers.fcm.MyFireBaseInstanceIDService"
        android:exported="false">
        <intent-filter>
            <action android:name="com.google.firebase.INSTANCE_ID_EVENT" />
        </intent-filter>
    </service>

    <service
        android:name="com.bnt.etailers.fcm.GCMNotificationIntentService"
        android:exported="false">
        <intent-filter>
            <action android:name="com.google.firebase.MESSAGING_EVENT" />
        </intent-filter>
    </service>

FirebaseInstanceIdService 类

FirebaseInstanceIdService class

public class MyFireBaseInstanceIDService extends FirebaseInstanceIdService {


private static final String TAG = MyFireBaseInstanceIDService.class.getSimpleName();

@Override
public void onTokenRefresh() {
    // Get updated InstanceID token.
    String refreshedToken = FirebaseInstanceId.getInstance().getToken();
    Log.d(TAG, "Refreshed token: " + refreshedToken);

    if (refreshedToken!=null) {
        SettingPreferences.setStringValueInPref(this, SettingPreferences.REG_ID, refreshedToken);
    }
    // TODO: Implement this method to send any registration to your app's servers.
    sendRegistrationToServer(refreshedToken);
}
// [END refresh_token]

/**
 * Persist token to third-party servers.
 *
 * Modify this method to associate the user's FCM InstanceID token with any server-side account
 * maintained by your application.
 *
 * @param token The new token.
 */
private void sendRegistrationToServer(String token) {
    // Add custom implementation, as needed.
}}

FirebaseMessagingService 类.

FirebaseMessagingService class.

public class GCMNotificationIntentService extends FirebaseMessagingService {
// Sets an ID for the notification, so it can be updated


public GCMNotificationIntentService() {
    super();
}


@Override
public void onMessageReceived(RemoteMessage message) {

}}
