我在android中有上述服务。有时我得到未捕获的异常，我的服务停止。我的执行线程进入UnCaughtExceptionHandler。我尝试重新启动服务，但它无法正常工作。任何人都可以帮我解决这个问题。
谢谢，NEHA

如果Service为Serice，您可以使用START_STICKY重新启动killed。您只需在START_STICKY
onStartCommand(Intent, int, int)即可
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
//your stuff
return Service.START_STICKY;
}
如果您将某些Intent传递给Service并获得killed，则可以退回Intent，您可以将该标记用作START_REDELIVER_INTENT

重新启动在运行时终止的任何服务，然后使用 Service.START_STICKY
答案 2 :(得分：0)
在您的服务类中使用此方法
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
return Service.START_STICKY;
}
使它表现得你想要。
