Answer 1

From the comments to the answers above, it seems like you want to create a Bitmap object from a stream of RGB values, not from any image format like PNG or JPEG.

This probably means that you know the image size already. In this case, you could do something like this:

byte[] rgbData = ... // From your server
int nrOfPixels = rgbData.length / 3; // Three bytes per pixel.
int pixels[] = new int[nrOfPixels];
for(int i = 0; i < nrOfPixels; i++) {
   int r = data[3*i];
   int g = data[3*i + 1];
   int b = data[3*i + 2];
   pixels[i] = Color.rgb(r,g,b);
}
Bitmap bitmap = Bitmap.createBitmap(pixels, width, height, Bitmap.Config.ARGB_8888);
