Question

我在Playstore上有一个应用，最近我只在Android 8.0设备上遇到了这些错误。请查看我从Google Play控制台收到的android stacktrace。我还包括了Firebase助手类。在此先感谢:)

'config';
$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = '1234';
$cfg['Servers'][$i]['extension'] = 'mysqli';
$cfg['Servers'][$i]['AllowNoPassword'] = true;
$cfg['Lang'] = '';

MyFirebaseMessagingService类

public class MyFirebaseInstanceIdService extends FirebaseInstanceIdService {

    private static final String REG_TOKEN = "REG_TOKEN";

    @Override
    public void onTokenRefresh() {

        String recent_token = FirebaseInstanceId.getInstance().getToken();
        Log.d(REG_TOKEN, recent_token);

    }
}

成绩文件：

public class MyFirebaseMessagingService extends FirebaseMessagingService {

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        Intent intent = new Intent(getApplicationContext(), OnlineActivity.class);
        intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent pendingIntent = PendingIntent.getActivity(getApplicationContext(), 0, intent, PendingIntent.FLAG_ONE_SHOT);
        NotificationCompat.Builder notifcationBuilder = new NotificationCompat.Builder(getApplicationContext());
        notifcationBuilder.setContentTitle("Dictionary Notification");
        notifcationBuilder.setContentText(remoteMessage.getNotification().getBody());
        notifcationBuilder.setAutoCancel(true);
        notifcationBuilder.setSmallIcon(R.mipmap.ic_launcher);
        notifcationBuilder.setContentIntent(pendingIntent);
        NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        if (notificationManager != null) {
            notificationManager.notify(0, notifcationBuilder.build());
        }

    }
}

这可能是由于Android 8 Oreo中引入了新的后台服务限制而导致的，请参阅： https://developer.android.com/about/versions/oreo/android-8.0-changes#back-all

一个建议的解决方案是使用JobScheduler（我这样做了），但这似乎不适合Firebase邮件接收器，因此您可能需要检查文档，以了解是否有一些提示。

android.app.ContextImpl.startServiceCommon上的java.lang.IllegalStateException
