Converting preview data to Bitmap?

Question

In following method,

public void onPreviewFrame4(byte[] data, Camera camera)

data is come in Yuv Format, is there any way for converting it to RGB, because i have tried it using following method

  static public void decodeYUV420SP(int[] rgba, byte[] yuv420sp, int width,
    int height) {
final int frameSize = width * height;

for (int j = 0, yp = 0; j < height; j++) {
    int uvp = frameSize + (j >> 1) * width, u = 0, v = 0;
    for (int i = 0; i < width; i++, yp++) {
        int y = (0xff & ((int) yuv420sp[yp])) - 16;
        if (y < 0)
            y = 0;
        if ((i & 1) == 0) {
            v = (0xff & yuv420sp[uvp++]) - 128;
            u = (0xff & yuv420sp[uvp++]) - 128;
        }

        int y1192 = 1192 * y;
        int r = (y1192 + 1634 * v);
        int g = (y1192 - 833 * v - 400 * u);
        int b = (y1192 + 2066 * u);

        if (r < 0)
            r = 0;
        else if (r > 262143)
            r = 262143;
        if (g < 0)
            g = 0;
        else if (g > 262143)
            g = 262143;
        if (b < 0)
            b = 0;
        else if (b > 262143)
            b = 262143;

        // rgb[yp] = 0xff000000 | ((r << 6) & 0xff0000) | ((g >> 2) &
        // 0xff00) | ((b >> 10) & 0xff);
        // rgba, divide 2^10 ( >> 10)
        rgba[yp] = ((r << 14) & 0xff000000) | ((g << 6) & 0xff0000)
                | ((b >> 2) | 0xff00);
    }
}

}

but it will not work properly for me.

Please provide any other way to convert it to Bitmap.

Thanks...!!!

You can set following property of camera to get preview in RGB image format than no need for conversion.

**Camera.Parameters.setPreviewFormat(ImageFormat.RGB_565);
