很抱歉，我是一个初学者。 由于违反了设备和网络滥用政策，我的第一个应用已被拒绝。
编辑：主要原因是关闭显示器后，Youtube视频不会停止播放... 一些信息在这里： Volating the Device and Network Abuse policy
我应该添加
@Override
public void onPause(){
super.onPause();
mWebView.onPause();
}
但是我应该在哪里插入这段代码？

答案 0 :(得分：0)
在“活动”类中想要的任何地方（您在问题中粘贴的那个）。
我通常会尝试按照Android执行生命周期方法的顺序对其进行排序，因此我将其放在onResume()
@Override
public void onResume() {
super.onResume();
asm_view.onResume(); //remember to add this so your WebView can resume
//Coloring the "recent apps" tab header; doing it onResume, as an insurance
if (Build.VERSION.SDK_INT >= 23) {
Bitmap bm = BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher);
ActivityManager.TaskDescription taskDesc;
taskDesc = new ActivityManager.TaskDescription(getString(R.string.app_name), bm, getColor(R.color.colorPrimary));
MainActivity.this.setTaskDescription(taskDesc);
}
get_location();
}
@Ovveride
public void onPause() {
super.onPause();
asw_view.onPause(); //your WebView variable is asm_view, not mWebView, which is just example code
}
答案 1 :(得分：0)
onPause是Activity（和Fragments）的生命周期方法，可以放置在Activity类的任何位置，但是将生命周期方法按执行顺序排列将有助于使代码更具可读性。
