NoSuchMethodError: libcore.io.IoUtils.closeQuietly when using URLConnection

Question

I get NoSuchMethodError: libcore.io.IoUtils.closeQuietly when I use URLConnectionon android 2.3.x

I use URLConnection to save file locally and use cache.

My app should run on android 2.3.x but compiled with API17 because of some AndroidManifest.xml defs.

I use JRE7. Maybe downgrading to JRE6 would help?

Any what causes it or how to solve it?

My code:

    public synchronized boolean saveFileLocally(String strUrl, String fileName) {
    boolean res = false;
    if (strUrl == null || fileName == null)
        return res;

    URL url = null;
    InputStream input = null;
    OutputStream output = null;
    try {
        url = new URL(strUrl);
        URLConnection connection;
        connection = url.openConnection();
        connection.setUseCaches(true);
        connection.connect();
        input = connection.getInputStream(); // HERE I GET THE EXCEPTION

        byte[] buffer = getTempBitmapStorage();
        output = new FileOutputStream(fileName);

        int bytesRead = 0;
        while ((bytesRead = input.read(buffer, 0, buffer.length)) >= 0) {
            output.write(buffer, 0, bytesRead);
        }

        res = true;
    } catch (MalformedURLException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } catch (Exception e) {
        e.printStackTrace();
    }

    if (input != null) {
        try {
            input.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    if (output != null) {
        try {
            output.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    return res;
}

See your error in locat and go to this link here:

public void closeSocketAndStreams() {
    IoUtils.closeQuietly(sslOutputStream);
    IoUtils.closeQuietly(sslInputStream);
    IoUtils.closeQuietly(sslSocket);
    IoUtils.closeQuietly(outputStream);
    IoUtils.closeQuietly(inputStream);
    IoUtils.closeQuietly(socket);
}

line 136 is: IoUtils.closeQuietly(inputStream);

We can see this method call IoUtils.closeQuietly with a InputStream parameter.

But when you see here to view IoUtils class

You can not find closeQuietly with a InputStream parameter. So, I think this is the cause of error. You should find another library or under version.

My english is not good. I'm sorry for the inconvenience caused to you
