How to get icons of Installed Applications in Android

I wanted to get icons of running activities And here I done it.

List<PackageInfo> packs = getPackageManager().getInstalledPackages(0);

Drawable[] icons=new Drawable[packs.size];

for(int i=0;i<packs.size();i++) {

    PackageInfo p = packs.get(i);

    icons[i]= p.applicationInfo.loadIcon(getPackageManager());

 }

And you may need to convert the return values to Bitmap.
