Android 杀掉自己进程的方法

Process.killProcess(Process.myPid());
代码如下
       protected void quit()       {
             int size = activityManager.activityStackCount();             for(int i =size-1  i > 0 i--)               {
                Activity activity =  activityManager.allTaskActivity().get(i);                  activityManager.popActivity(activity);               }
              activityManager = null;              getActivity().finish();
            //目前最为通用的关闭进程的方法以后的版本使用
            Intent startMain = new Intent(Intent.ACTION_MAIN);             startMain.addCategory(Intent.CATEGORY_HOME);             startMain.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);             startActivity(startMain);
           android.os.Process.killProcess(android.os.Process.myPid());      }

android.os.Process.killProcess(appProcessInfo.pid);只能杀死自己所创建的进程，其它进程是杀不掉的，要用到另外一个方法
activityManager.killBackgroundProcesses(processName);,同是权限也要加上 android:name="android.permission.KILL_BACKGROUND_PROCESSES" />
以下是我的测试代码
public class ListViewActivity extends Activity {
/** Called when the activity is first created. */
private Button button;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
  setContentView(R.layout.main);
  button = (Button) findViewById(R.id.button);
  button.setOnClickListener(
new OnClickListener() {
@Override
   public void onClick(View v) {     killAll(getApplicationContext());    }   });  }
public static void killAll(Context context) {    //获取一个ActivityManager 对象
        ActivityManager activityManager =
(ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);    //获取系统中所有正在运行的进程
       List appProcessInfos =
activityManager.getRunningAppProcesses();   //获取当前activity所在的进程
      String currentProcess=context.getApplicationInfo().processName;
  //对系统中所有正在运行的进程进行迭代，如果进程名不是当前进程，则Kill掉
for (RunningAppProcessInfo appProcessInfo : appProcessInfos) {
String processName=appProcessInfo.processName;
if (!processName.equals(currentProcess)) {
          System.out.println("ApplicationInfo-->"+processName);
          activityManager.killBackgroundProcesses(processName);
           System.out.println("Killed -->PID:"+appProcessInfo.pid+"--ProcessName:"+processName);
}           }   } }
