android:关闭应用程序后它仍在运行 [英] android: after closing the app its still running

问题描述

我正在使用 webview，并且我正在附加一些带有 URL 的查询字符串.假设 URL 是 file:///android_asset/www/index.html 并且我添加了查询字符串 ?urlid=MindTree_Projects&city=bangalore&firstTimeRule=%7B%22EEI ....something.所以整个 URL 看起来像 file:///android_asset/www/index.html?urlid=MindTree_Projects&city=bangalore&firstTimeRule=%7B%22EEI....something.现在假设我打开应用程序然后关闭它，它仍在运行，但在前台已关闭.

I am using webview, and I'm appending some query string with the URL. Say URL is file:///android_asset/www/index.html and I have added the query string ?urlid=MindTree_Projects&city=bangalore&firstTimeRule=%7B%22EEI....something. So the whole URL looks like file:///android_asset/www/index.html?urlid=MindTree_Projects&city=bangalore&firstTimeRule=%7B%22EEI....something. Now suppose I open the app and then close it, still its running, but in foreground its closed.

只有我能看到它在 chrome://inspect 中运行.这是调试网络应用的方法之一.

Only I can see it running in chrome://inspect. Which is one of the way to debug web apps.

任何人都可以告诉我为什么会发生这种情况，这对我来说是值得的.

Can any body tell me why this is happening, it worth for me.

推荐答案

您可能需要调用 onPause() 和 onResume()="http://developer.android.com/reference/android/webkit/WebView.html" rel="nofollow">WebView 类.

You may have to call the methods onPause() and onResume() of the WebView Class.

@Override
protected void onPause()
{
    super.onPause();
    mWebView.onPause(); // pauses the WebView (JavaScript, flash etc.)
}

@Override
protected void onResume()
{
    super.onResume();
    mWebView.onResume(); // resumes the WebView (JavaScript, flash etc.)

}

@Override
protected void onDestroy()
{
    super.onDestroy();
    relativeLayoutPlaceholder.removeView(mWebView); // removes the WebView from its Placeholder
    mWebView.destroy(); // destroys the WebView
    mWebView = null;
}
