Question

I am working on an application that uses HttpUrlConnection, connects beautifully with the server, but when fetching data from it says connection time out IOException.

The internet, & network permissions are already set in the android.manifest; there are no bars showing up in the android emulator (does this says anything).

Read at developer.android.com:
The functional limitations of the emulator include:
– No support for determining network connected state
– and few others….

Any help will be highly appreciated. And I don’t have an actual device to test this.

Received server info do gets printed in the logcat.

Thanks…

Here is the code:

URL url = new URL(urlString);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
try {
    Log.i(INFO_TAG, "Received server:" + conn.toString());
    conn.setInstanceFollowRedirects(true);
    conn.setRequestMethod("GET");
    conn.setRequestProperty("Content-length", "0");
    conn.setUseCaches(false);
    conn.setAllowUserInteraction(false);
    conn.setConnectTimeout(25000 /* milliseconds */);
    conn.setReadTimeout(15000/* 10000 *//* milliseconds */);
    // conn.setDoInput(true);
    // Starts the query
    conn.connect();
    status = conn.getResponseCode();
    Log.d(DEBUG_TAG, "Status recevied is: " + conn.getResponseCode());
    responseCode = status;
    if (responseCode == 200) {
        Log.i(INFO_TAG, "URL Connection OK");
        contentIs = conn.getInputStream();
        BufferedReader reader = new BufferedReader(
                new InputStreamReader(contentIs));
        String line;
        while ((line = reader.readLine()) != null) {
            builder.append(line);
            Log.i(INFO_TAG, "Data Read is: " + line);
        }
    } else {
        Log.d(DEBUG_TAG, "Could not read data from web server");
        Log.e(ConnectAndGetData.class.toString(),
            "Failed to download content");
    }
}// end of try
catch (Exception ex) {
    // This is currently being printout
    Log.d(DEBUG_TAG, "Received an exception" + ex.toString(), ex);
    ex.printStackTrace();
    throw new IOException("Error Connecting" + ex.toString());// "Error connecting");
} finally {
    if (contentIs != null) {
        contentIs.close();
        conn.disconnect();
    }
}

One more thing since, it throws a connection timeout exception it does not debug info at this line is printed:
Log.d(DEBUG_TAG, “Status recevied is: ” + conn.getResponseCode());

The problem was not the code above, it was the server code (the main culprit). Now implemented a web service and the code above is working fine.
