怎么关闭chrome呀？

我试了好几天也不行：

1.把chrome弄到后台，然后调用

activityManager.killBackgroundProcesses("com.android.browser");

看看后台，chrome还在。

2.把chrome弄到后台，然后调用
public void killChromeProcess() {
ActivityManager activityManager = (ActivityManager) this
.getSystemService(ACTIVITY_SERVICE);

List<RunningAppProcessInfo> procInfos = activityManager
.getRunningAppProcesses();

for (int idx = 0; idx < procInfos.size(); idx++) {
String processName = procInfos.get(idx).processName;

Log.e("ActionService find chrome", Integer.toString(idx)+": "+processName);
Log.e("importance : ", Integer.toString(procInfos.get(idx).importance));

String chrome = "com.android.chrome";//"com.android.chrome:sandboxed_process";//

//kill chrome process
if (processName.indexOf(chrome) != -1) {
Log.e("ActionService kill chrome", Integer.toString(idx)+": "+processName);

activityManager.killBackgroundProcesses(processName);

//Method forceStopPackage = activityManager.getClass().getDeclaredMethod(forceStopPackage, String.class);
//forceStopPackage.setAccessible(true);
//forceStopPackage.invoke(activityManager, processName);
}
}
}

看看后台，chrome还在。
