If you are working on Android Studio and you get the above Stack-trace while running your Android Application, then the reason mostly is that you have missed adding ACCESS_NETWORK_STATE user permission in the AndroidManifest.xml file.

Just add the following lime above the application tag in the Manifest.

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
