You can use the Palette API to extract the prominent colors from bitmap images. Add the following dependency in gradle:

dependencies {
  compile 'com.android.support:palette-v7:23.1.1'
}

Create the palette object :

 Palette.PaletteAsyncListener paletteListener = new Palette.PaletteAsyncListener() {
  public void onGenerated(Palette palette) {
    // access palette colors here
  }
}

Bitmap myBitmap = BitmapFactory.decodeResource(getResources(), R.drawable.nyancat);
if (myBitmap != null && !myBitmap.isRecycled()) {
    Palette.from(myBitmap).generate(paletteListener);
}
