I have some typical codes which used HttpURLConnection to get a file with an URL. They worked fine in android 1.x and 2.x. But failed in Android 4.1!
I searched on the web but found little similar information. Would anybody please help to investigate this issue?
private String mURLStr;
private HttpURLConnection mHttpConnection;
...
url = new URL(mURLStr);
...
mHttpConnection = (HttpURLConnection) url.openConnection();
mHttpConnection.setDoOutput(true);
mHttpConnection.setRequestMethod("GET");
...
InputStream is = mHttpConnection.getInputStream();
The getInputStream method throws an exception:
