This week's developer video features Jason Tomlinson of Hands-On Mobile. He wrote Amazed, an application open sourced in the apps-for-android project. Things Jason mentions in the videos include:
Amazed was built primarily to get familiar with the accelerometer. This helped him in his work on Guitar Hero® World Tour Mobile for Android.
Using traceview to track down which methods take the most CPU cycles.
