There is a android-support-v7-palette.jar in the SUPPORT-V7 library on API21 that allows you to extract some prominent colors from the image:
Palette p = palette.generate (Bitmap Bitmap);
• Vivid P.getvibrantcolor (int defaultcolor);
• Vivid Dark P.getdarkvibrantcolor (int defaultcolor);
• Vivid bright P.getlightvibrantcolor (int defaultcolor);
• Soft P.getmutedcolor (int defaultcolor);
• Soft Dark P.getdarkmutedcolor (int defaultcolor);
• Soft bright P.getlightmutedcolor (int defaultcolor);
Palette.generate (), used in a background thread, can use Palette.generateasync () if the Palette object is created in the foreground thread.
