// You are using RGBA that's why Config is ARGB.8888
    bitmap = Bitmap.createBitmap(100, 100, Bitmap.Config.ARGB_8888);
 // vector is your int[] of ARGB
    bitmap.copyPixelsFromBuffer(IntBuffer.wrap(vector));

//OR , you can generate IntBuffer from following native method
  /*private IntBuffer makeBuffer(int[] src, int n) {
        IntBuffer dst = IntBuffer.allocate(n*n);
        for (int i = 0; i < n; i++) {
            dst.put(src);
        }
        dst.rewind();
        return dst;
    }*/

int[] array  = your array of pixels here...
int   width  = width of "array"...
int   height = height of "array"...

// Create bitmap
Bitmap bitmap = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);

// Set the pixels
bitmap.setPixels(array, 0, width, 0, 0, width, height);
