This helper function retrieves all installed apps with the application name, package name, version-number and -code as well as the icons. The method getPackages() returns an ArrayList with all the apps.

It depends what you want to do, but you can use getPackages() to return you an ArrayList of all the installed items.

if you are getting error in Log.v(appname + "t" + pname + "t" + versionName + "t" + versionCode); then replace this line with System.out.println(appname + "t" + pname + "t" + versionName) + "t" + versionCode + "t");

I'm very new to Android development and I'm not really sure how to use this snippet. Would someone please provide me with an example? (Maybe a blank gui using this?)

Thanks!

Hi, been working on your snippets for quite some time now and unfortunately, it does show system apps, no matter what I do.

Tried modifying the continue statement to: if ((packs.get(i).versionCode & ApplicationInfo.FLAG_SYSTEM) == 1 && !getSysPackages) { continue; } it does screen most system apps but not all of them and also removes some user installed apps, so it's no good...

Would love if you can update you code or tell me what i'm missing here :)

Never mind, here is the right if statement: if ((packs.get(i).applicationInfo.flags & ApplicationInfo.FLAG_SYSTEM) == 1) { continue; }

Thank you for the rest of the great code!
