Is there a recommended method for app updates?

 So as of Android 1.1 (which almost everyone has been running for the
past few months), the Market app automatically checks for updates
without any extra work on the developer's part.  It shows a
notification to the user, something like "3 updates available" and the
user can choose which ones to upgrade.

You could also roll your own update checking if you'd like, and
several developers have open-sourced small libraries to help with

1. RGB from bitmap

        if you are using bitmap, use an integer array to store the bitmap.
use bitmap.getPixel() to get the corresponding bitmap in integer array. By
using bitwise rotation operation, we will get RGB values. (Also byte array
can be used). See the code below.

             int[] pix = new int[picw * pich];
            bitmap.getPixels(pix, 0, picw, 0, 0, picw, pich);

            int R, G, B,Y;

            for (int y = 0; y < pich; y++)
            for (int x = 0; x < picw; x++)
                int index = y * picw + x;
                int R = (pix[index] >> 16) & 0xff;     //bitwise shifting
                int G = (pix[index] >> 8) & 0xff;
                int B = pix[index] & 0xff;

                //R,G.B - Red, Green, Blue
                 //to restore the values after RGB modification, use //next
                pix[index] = 0xff000000 | (R << 16) | (G << 8) | B;

2. how does one change the font COLOR in an applicaton

How would one go about changing the FONT COLOR in your app??  Most
font colors are black with a white background with an EdiTText or
TextView.  Does anyone know of a "LIBRARY" that out there that can be
used with Eclipse.??
