Referred Link from Github : https://gist.github.com/evandrix/7058235 can anyone help pls? Thanks in Advance..
I think error is here :
try
{
InputStream inputStream = ...
}
assert inputStream != null; // here
inputStream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
Try to declare InputStream inputStream; before oncreate() with all other variables.
