How to fix android.os.NetworkOnMainThreadException
What is NetworkOnMainThreadException:
In Android all the UI operations we have to do on the UI thread (main thread). If we perform background operations or some network operation on the main thread then we risk this exception will occur and the app will not respond.
How to fix it:
To avoid this problem, you have to use another thread for background operations or network operations, like using asyncTask and use some library for network operations like Volley, AsyncHttp, etc.
