httpclient.getCredentialsProvider().setCredentials(new AuthScope(null, -1),
                    new UsernamePasswordCredentials("kyaw", "password"));
get.setHeader("Authorization","Basic a31hdzpwYXNzd29yZA==");

The error is "You must supply a layout_width attribute" (copy pasted from your stack trace).

The error is unrelated to the code you are showing. You are missing a layout_width="" attribute in one of your components XML declaration.
