我们只是将应用程序的目标api迁移到Android API 27（8.1），当在后台运行该应用程序时，当通知特别到达时，它会继续崩溃。

这是解决问题的方法：

为什么会发生此问题？

由于新版的Android 8 Background Execution Limits，您应该无法启动服务背景。

我如何修复

将您的GCMIntetService迁移到JobIntentService而不是IntentService。

请按照以下步骤操作： 1）将BIND_JOB_SERVICE权限添加到您的服务中：

<service android:name=".service.GCMIntentService"
        android:exported="false"
        android:permission="android.permission.BIND_JOB_SERVICE"/>

2）在您的GCMIntentService中，而不是扩展IntentService，请使用android.support.v4.app.JobIntentService并覆盖onHandleWork 然后从您的override中删除onHandleIntent。

public class GCMIntentService extends JobIntentService {

    // Service unique ID
    static final int SERVICE_JOB_ID = 50;

    // Enqueuing work in to this service.
    public static void enqueueWork(Context context, Intent work) {
        enqueueWork(context, GCMIntentService.class, SERVICE_JOB_ID, work);
    }

    @Override
    protected void onHandleWork(@NonNull Intent intent) {
        onHandleIntent(intent);
    }

    private void onHandleIntent(Intent intent) {
        //Handling of notification goes here
    }
}

最后，在您的GCMBroadcastReceiver中，将您的GCMIntentService放入队列。

public class GCMBroadcastReceiver extends WakefulBroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        // Explicitly specify that GcmIntentService will handle the intent.
        ComponentName comp = new ComponentName(context.getPackageName(),
                GCMIntentService.class.getName());
        // Start the service, keeping the device awake while it is launching.
        // startWakefulService(context, (intent.setComponent(comp)));

        //setResultCode(Activity.RESULT_OK);

        GCMIntentService.enqueueWork(context, (intent.setComponent(comp)));
    }
}

在我们将目标sdk更新为27之后，该实现对我有用，我希望它对您有用。
