there are many images in drawable foder so instead manually creating array of all image resource ids , i want to get all images dynamically of drawable folder in array. cur
Well, If your image names are img1, img2 and so on, then you can create a variable like
String url = "drawable/"+"img"+i;
int imageKey = getResources().getIdentifier(url, "drawable", getPackageName());
you can also replace your getPackageName() method by your package name like "com.android.resource"
Simply,the general function is
public int getIdentifier(String name, String defType, String defPackage)
