I don't know if this is the right forum, so please forgive me if it isn't
During the development of Minimalistic Text I came across the lack of a good color picker view for Android.
In the first attempt I used the one from the samples (The "Ring").
The second attempt has been to integrate this one and add the possibility to change the alpha channel.
In the end I decided to build my own.
To let you use this color picker and - if you like to and are able to - improve it, I've extracted it into an Android library project and made it open source.
It's hosted at Google Code:
The code has almost no code comments. I will add them if I have time.
At the moment it is localized to German and English.
Please let me know what you think and write me an email if you want to contribute.
Here are some screenshots (in German):
