我正在开发android wrein中的应用程序我调用一个服务，它会将一个xml文件上传到服务器上，单击一个按钮。问题是当我第一次单击该按钮时，上传，但当我点击按钮第二次获取上传...所以让我知道是否有任何解决方案..请帮助我。使用Android服务将xml文件上传到服务器

在onStart（意向意图，诠释startId）这种方法在API级别被废弃5.实现onStartCommand（意向，int，int）。 – mromer

尝试与onStartCommand（意图，诠释，int）但相同的结果..它不适用于第一次点击.. – Yogi

请将您的活动代码 – mromer

onStartCommand意图：

这可能是如果服务空在其进程已经消失后正在重新启动，并且它之前已经返回任何东西细节 START_STICKY_COMPTIBILITY。

http://developer.android.com/reference/android/app/Service.html

因此，尝试使用：

Intent intent = new Intent(Intent.ACTION_MAIN); 
intent.addCategory(Intent.CATEGORY_HOME); 
startActivity(intent);

而不是finish();

谢谢...我试过了并包括你说的ie wate而不是finish（），但同样的问题不工作的第一次，但第二次工作........ – Yogi

把登录onStart（）下面看看是否服务执行两次 – mromer
