我的
Android应用程序的一项活动包含一个显示GrooveShark播放器网页的WebView.当用户点击网页的播放按钮时,活动会自动启动播放该轨道的默认MediaPlayer.一切正常,问题出现在用户关闭此活动和MediaPlayer时,虽然不再播放音轨,但它仍然存在……即使应用程序关闭,MediaPlayer仍然存在.杀死它的唯一方法就是强迫应用程序停止……我似乎没什么大不了的,但在某些设备中,当用户在通话后挂机时,这个“僵尸”MediaPlayer突然开始播放即使该应用程序之前已被破坏,该轨道……
这是我的活动代码的摘要：
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_song);
myWV = (WebView) findViewById(R.id.webview);
WebSettings webSettings = myWV.getSettings();
webSettings.setJavaScriptEnabled(true);
myWV.setWebViewClient(new MyWebViewClient());
myWV.setWebChromeClient(new WebChromeClient());
myWV.loadUrl(url);
}
@Override
protected void onPause() {
// TODO Auto-generated method stub
super.onPause();
myWV.onPause();
myWV.pauseTimers();
}
@Override
protected void onResume() {
// TODO Auto-generated method stub
super.onResume();
myWV.onResume();
myWV.resumeTimers();
}
@Override
protected void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
myWV.destroy();
}
private class MyWebViewClient extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (Uri.parse(url).getHost().equals("grooveshark.com")) {
return false;
}
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
startActivity(intent);
return true;
}
}
这是第一次播放曲目时日志显示的内容：

我需要找到一种方法来检索“僵尸”MediaPlayer并停止它……
非常感谢
