    PackageInfo info = pm.getPackageArchiveInfo(apkPath, 
            PackageManager.GET_ACTIVITIES);
    if (info != null) {
        ApplicationInfo appInfo = info.applicationInfo;
        appInfo.sourceDir = apkPath;
        appInfo.publicSourceDir = apkPath;
        try {
            return appInfo.loadIcon(pm);
        } catch (OutOfMemoryError e) {
            Log.e(TAG, e.toString());
