  • `BuildConfig.VERSION_CODE` provides the version code defined in your build.gradle file. – M. Palsich Jul 08 '17 at 01:32

Get all install app info:

 List<PackageInfo> packList = getPackageManager().getInstalledPackages(0);
            for (int i=0; i < packList.size(); i++)
            {
                PackageInfo packInfo = packList.get(i);
                if (  (packInfo.applicationInfo.flags & ApplicationInfo.FLAG_SYSTEM) == 0)
                {
                    String appName = packInfo.applicationInfo.loadLabel(getPackageManager()).toString();
                    ;
                    Log.e("App " + Integer.toString(i), appName +"  ver: "+packInfo.versionCode);
                }
            }

You need to iterate all application installed the app, then get each of the package name to get the package info.. in packageInfo have infomation about those app

final PackageManager packageManager = getPackageManager();
List<ApplicationInfo> installedApplications = packageManager.getInstalledApplications(PackageManager.GET_META_DATA);

List<String> vers = new ArrayList<>();

for (ApplicationInfo appInfo : installedApplications)
{
    PackageInfo packageInfo = getPackageManager().getPackageInfo(appInfo.packageName, 0);
    vers.add(packageInfo.versionName);
} 

Log.i(TAG,vers.toString());
