Load app hi-res icon

Short snippet how to load hi-res icon of the app by its package name.

By default when you request some app icon from PackageManager you get icon for device density, which is pretty obvious.

public static Drawable loadAppIcon(Context pContext, String packageName){
    try {
        PackageManager packageManager = pContext.getPackageManager();
        ApplicationInfo applicationInfo = packageManager.getApplicationInfo(packageName, PackageManager.GET_META_DATA);
        return applicationInfo.loadIcon(packageManager);
    } catch (PackageManager.NameNotFoundException e) {

    }
    return null;
}

But if you want to display this icon larger then it is (46dp) you need to load higher resolution version of icon to prevent pixilisation.

If your min sdk is >= 15 you can use this code:

try {
    PackageManager packageManager = pContext.getPackageManager();
    ApplicationInfo applicationInfo = packageManager.getApplicationInfo(packageName, PackageManager.GET_META_DATA);
    if (applicationInfo.icon!=0){
        Resources lResources = packageManager.getResourcesForApplication(applicationInfo);
        return lResources.getDrawableForDensity(applicationInfo.icon, DisplayMetrics.DENSITY_XXXHIGH);
    }
    return applicationInfo.loadIcon(packageManager);
} catch (PackageManager.NameNotFoundException e) {

}

Enjoy!
