SecurityException: Permission denied (missing INTERNET permission?), it clearly indicates that you are not allowed to do networking.
Usually it is either due to missing <uses-permission android:name="android.permission.INTERNET" /> entry in your AndroidManifest.xml file
OR
As internet permission is granted at installation not at run time, by long standing, missed bug in Android framework that causes your app to be successfully installed, but without expected permission grant.
