Check if color is dark or light in Android

Android doesn’t provide it, you can implement a method to determine this. Here a method to do that:

public boolean isColorDark(int color){
    double darkness = 1-(0.299*Color.red(color) + 0.587*Color.green(color) + 0.114*Color.blue(color))/255;
    if(darkness<0.5){
        return false; // It's a light color
    }else{
        return true; // It's a dark color
    }
}
