This morning I finally released my calculation application about current and voltage. I know there are a lot of other applications that can do this too, but I wanted to publish the application. I think the application is very basic but okay. Another thing is, that I developed the whole application in German.
A lot of things changed since I last published an application, and the tutorial got even longer: http://developer.android.com/tools/publishing/app-signing.html
The main reason I developed the app was that I wanted to work with the new Navigation Drawer. Take a look at it in the following screen:
But a least there is one good thing, the code of my app is opensource, so you can check it out yourself and feel free to download the app in the play store.
