问题 I am working of new Android L preview and now dealing with tinting concept on drawable. I want to know if there is anything new regarding drawable tinting in Android L Developer Preview.

You can create these assets only

问题 According to what I've read, you can use a gradientDrawable and have three colors set for it, for example: <gradient startColor="#00FF00" centerColor="#FFFF00" endColor="#FFFFFF"/> But what if I want more than three colors, and not only that, I want to be able to set where to put each (in weight/percentage)?

问题 I am successfully building a 9patch drawable at runtime on Android 3.0+ using the excellent gist provided by Brian Griffey (found here). Essentially I load the raw (no patches) graphic file from the network and the filename contains the cap insets that I need to use in order to scale the image accordingly.
