Question

我正在获取令牌并通过Firebase Notification Composer发送通知。它已成功发送，但在onMessageReceived方法中未收到。我不知道这里是什么问题。我做了firebase控制台中提到的所有步骤。请帮助我。我的清单就是这样

KaROFirebaseInstanceIDService为

public class KaROFirebaseInstanceIDService extends FirebaseInstanceIdService {
    private static final String TAG = "MyFirebaseIIDService";

    /**
     * Called if InstanceID token is updated. This may occur if the security of
     * the previous token had been compromised. Note that this is called when the InstanceID token
     * is initially generated so this is where you would retrieve the token.
     */
    // [START refresh_token]
    @Override
    public void onTokenRefresh() {
        // Get updated InstanceID token.
        String refreshedToken = FirebaseInstanceId.getInstance().getToken();
//        KaHOAppController.setLoggedInUserDeviceID(refreshedToken);
        Log.d(TAG, "Refreshed token: " + refreshedToken);

        // If you want to send messages to this application instance or
        // manage this apps subscriptions on the server side, send the
        // Instance ID token to your app server.
        sendRegistrationToServer(refreshedToken);
    }
    // [END refresh_token]

    /**
     * Persist token to third-party servers.
     * <p>

     */
    private void sendRegistrationToServer(String token) {
        // TODO: Implement this method to send token to your app server.
    }
}

KaROFirebaseMessagingService为

public class KaROFirebaseMessagingService extends FirebaseMessagingService {
    private static final String TAG = "FCM Service";
    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        // TODO: Handle FCM messages here.
        // If the application is in the foreground handle both data and notification messages here.
        // Also if you intend on generating your own notifications as a result of a received FCM
        // message, here is where that should be initiated.
        Log.d(TAG, "From: " + remoteMessage.getFrom());
        Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody());
    }
}

对我来说，问题是我没有指定调试证书的SHA-1哈希。 docs中没有明确提及。

您可以按以下方式获取调试证书的哈希值：

keytool -list -v \
-alias androiddebugkey -keystore ~/.android/debug.keystore

找到更多相关信息，例如如何在Authenticating Your Client
