Are there any frameworks out there which make it even more easy than it is to build Android applications and would you be interested in one?
Not really a 'software framework', but a tool to create simple apps easily (that's what Google says):

I don't use this tool since I'm not a big fan of this approach, but you could give it a try.
You can build many different types of apps with App Inventor. Often people begin by building games like MoleMash or games that let you draw funny pictures on your friend's faces. You can even make use of the phone's sensors to move a ball through a maze based on tilting the phone.
But app building is not limited to simple games. You can also build apps that inform and educate. You can create a quiz app to help you and your classmates study for a test. With Android's text-to-speech capabilities, you can even have the phone ask the questions aloud.
To use App Inventor, you do not need to be a developer. This is because instead of writing code, you visually design the way the app looks and use blocks to specify the app's behavior.
