Last week we introduced a couple Android developers who shared how they built their Android apps and gave their insight into Android app development. This week, we have videos of two developers who've built music-related apps.

The first is of Allan Hsu—he wrote imeem's Android app. A couple of things he mentions in his videos:

Using SQLite databases and regular expressions
Completing the app, including rewriting many of their Activities and web service API calls, in just 6 weeks.

The second video features Casey Langen—he wrote the Amazon MP3 for Android app. Things he mentions in the videos include:

Using Apache HTTPClient to download data from their servers. Also used ListView in all activities and the MediaPlayer for song previews.
Developers new to Android should get familiar with ViewGroups and how they're implemented.
