True, the amount is not quality and good examples cover the possible applications on Android (GPS, Internet, SMS, etc.), but flying over them. The source code, lack of space is not always well documented and often requires a real effort to understand (decryption for the neophyte that I am). I also found much clearer on the web, for example here: [...] In short, over 30 for a guided tour at a run on Android, it is expensive paid.
