完全关闭Android应用

工作过程序中遇到一个需要完全关闭应用程序的问题，每篇都是用System.exit(0)或者android.os.Process.killProcess(android.os.Process.myPid())这两种方法，但是我试过了，System.exit(0)这个根本不行，而android.os.Process.killProcess(android.os.Process.myPid())这个只能关闭当前的Activity，也就是对于一个只有单个Activity 的应用程序有效，如果对于有多外Activity的应用程序它就无能为力了。
         
Android 方法名误导不少人呀！！！下面介绍一下对于多个Activity的应用程序的完全关闭方法：

Java代码：

/**

 

* Have the system perform a force stop of everything associated with

 

* the given application package. All processes that share its uid

 

* will be killed, all services it has running stopped, all activities

 

* removed, etc. In addition, a {@link Intent#ACTION_PACKAGE_RESTARTED}

 

* broadcast will be sent, so that any of its registered alarms can * be stopped, notifications removed, etc.

 

*

 

* You must hold the permission * {@link android.Manifest.permission#RESTART_PACKAGES} to be able to

 

* call this method.

 

*

 

* @param packageName The name of the package to be stopped.

 

*/

 

public void restartPackage(String packageName) {

 

try {

 

ActivityManagerNative.getDefault().restartPackage(packageName);

 

}

 

catch (RemoteException e) { }

 

}

       所以如果要关闭整个应用程序的话只需要运行以下两行代码就行：

Java代码：

ActivityManager activityMgr= (ActivityManager) this.getSystemService(ACTIVITY_SERVICE);

 

activityMgr.restartPackage(getPackageName());

<!-- 关闭应用程序的权限 -->

<uses-permission android:name="android.permission.RESTART_PACKAGES" />
