Get pixel color in Android

How to get the color at fixed pixels:

this is my code 

public static void getColor(Bitmap btm,Activity act){
    int w = 300;
    int h = 500;
    btm=Bitmap.createScaledBitmap(btm, w,h, true);

    color1= btm.getPixel(30, 50);
    color2= btm.getPixel(50, 70);

}

Try this. I've used it to get the predominant color of an image. 

public static int getDominantColor(Bitmap bitmap) {
    Bitmap newBitmap = Bitmap.createScaledBitmap(bitmap, 1, 1, true);
    final int color = newBitmap.getPixel(0, 0);
    newBitmap.recycle();
    return color;
}

The problem is not in the method that you have shared, its the way you are generating the bitmap and passing it to this function that has different sizes on different devices.

Just because you are scaling the device to a definite size does not mean that all pixels will have the same color for different screen sizes. This problem cannot be fixed by reading color from bitmap, so you have to explain the actual purpose, so we can solve it with different techniques.
