I'm running an android app that displays a webview on specific URL, I want to check if the application server I'm accessing is alive and that I can view HTML, if failed I should terminate the webview, this check should be every 10 seconds (or whatever), what is the best approach for this ?
推荐答案
创建定时器 (在这里你有资料),当计时器滴答,平任何主机:
Create Timer (here you have information) and when timer tick, ping any host :
URL url = new URL("http://microsoft.com");
HttpURLConnection urlc = (HttpURLConnection) url.openConnection();
urlc.setRequestProperty("User-Agent", "Android Application:"+Z.APP_VERSION);
urlc.setRequestProperty("Connection", "close");
urlc.setConnectTimeout(1000 * 30); // mTimeout is in seconds
urlc.connect();
if (urlc.getResponseCode() == 200) {
Main.Log("getResponseCode == 200");
return new Boolean(true);
}
} catch (MalformedURLException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
如果还真:连接处于活动状态。否则无效。
If return true : connection is active. Else isn't active.
