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 [email protected] 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 * [email protected] 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" />
