Curt is a simple activity.

Curt can not do much. But he can show the methods / callbacks in its LiveCycle. In each callback he gives a toast from a short message to show what's happening right now. This is not much, and certainly not exciting - but it should not be.

Curt is only for educational purposes and as it as an example of the methods of Live Cycles, in the lecture on the JAX in Mainz or in the revised edition of the book was presented to "Android Quick Start".
The short source code of the Java file can be downloaded at http://curt.punktuelles-in-web.net. If you want to have a small project with all the files, it can feel free to ask via email.
