Java.lang.runtimeexception Error Occured While Executing Doinbackground()?

I am beginner in android, and for a project for a uny course we have to develop 5 simple apps and then 'combine' them in one.So you start each app from a single Activity/ListView.

Solution 1:

It appears you don't have the appropriate permissions. Add this line to your manifest.xml

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