Question

当我尝试在IntentService中保存Realm对象时，我收到以下异常。我的猜测是服务在Realm save实际发生之前被杀死了，但是我不确定如何解决这个问题？

我认为这里的问题是由IntentService管理的另一个线程。系统将使用与此线程关联的Handler，特别是如果您还尝试处理某些UI（如Toast，将数据发送到activity，片段等等）。

要解决此问题，您可以尝试以这种方式打开领域：

Realm realm = Realm.getInstance(getApplicationContext());

并设置

realm.setAutoRefresh(false);

如何在IntentService中保存Realm对象？
