我正在开发一项服务来获取当前的 sim 卡值并检测 sim 卡是否更改，如果是，我想在我的服务中实现 JavaMail API，这意味着我的服务能够发送电子邮件。
下面是我的代码，MyService.java 中的代码错误
在排队
public class GMailAsync extends AsyncTask<String, Void, String>
显示错误
illegal modifier for the local class GMailAsync; only abstract or final is permitted
有人可以指导我吗？我想让我的服务在没有用户交互的情况下发送电子邮件。
我的服务.java

String storedSimSerial;

storedSimSerial = telephoneMgr.getSimSerialNumber();
Log.e("SimSerial::",storedSimSerial);
TelephonyManager tmMgr = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
currentSimSerial = tmMgr.getSimSerialNumber();
Log.e("Current Sim Serial::",currentSimSerial);
if(currentSimSerial.equals(storedSimSerial))
{
Log.e("Sim Status","Sim no changed !!!");
