Use this code in "onCreate()" method

//////////////////////////////////////////////////////////////////////////////////

try {
if(android.os.Build.VERSION.SDK_INT>9)
{
StrictMode.ThreadPolicy policy=new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
}

} catch (Exception e) {
// TODO: handle exception
}
