Hallo, ich hab in meiner App kein Internetzugriff trotz gesetzter permission.INTERNET!

ich hab leider kein plan was, warum oder wie ich anfangen soll?!
gegoogelt hab ich schon, requestPermission() geht bei mir nicht, weil mein sdk version 14 ist!
deswegen schicke ich einfach mal den Code und mein Manifest, ich hoffe jemand kann mir weiterhelfen!

PS blutiger android studio anfänger aber nicht programmieranfänger

EDIT: app läuft auf einem emulator, falls das eine rolle spielt
