When i run this code only a few lines of the HTML of website is downloaded and not the whole.

This is the logcat.

The end few lines are the HTML of website which i have removed. I accessed INTERNET permission also in AndroidManifest.xml. Tried using AsyncDownload <String, Void, String also but doesn't work and also its depricated now. I am pretty sure this problem is not because of my Internet connection as i am using a broadband so this is a problem of my code.

Please help me with this i am a beginner.
