Bitmap image = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
Canvas canvas=new Canvas (image);
int HEX=0xFF888888;
canvas.drawColor (HEX);

I think I may have the answer. Technically I believe it is much easier on Android than on a "pc". The last time I searched to create a bitmap (.bmp), I only found some Android functions and the BitmapFactory for non-android, which didn't work for me.

Please look at this site: http://developer.android.com/reference/android/graphics/Bitmap.html
This point could fit for you:

static Bitmap createBitmap(int[] colors, int offset, int stride, int width, int height, Bitmap.Config config)

Returns a immutable bitmap with the specified width and height, with each pixel value set to the corresponding value in the colors array.

Alternatively, you can use Bitmap.eraseColor() to set a solid color for your bitmap.

Example:

  import android.graphics.Bitmap;
  ...
  Bitmap image = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
  image.eraseColor(android.graphics.Color.GREEN);
