Android App Icon Filemanager

Question

I want to add an option in my file manager to show the App Icons of a directory. The code below didn't work; what did I do wrong?

ImageView icon;
private static Activity activity;
String temp = mFileMang.getCurrentDir();

} else if (sub_ext.equalsIgnoreCase("apk")) {
                final Drawable appicon;
                try {
                    PackageInfo packageInfo = activity.getPackageManager()
                            .getPackageArchiveInfo(temp,
                                    PackageManager.GET_ACTIVITIES);
                    ApplicationInfo appInfo = packageInfo.applicationInfo;

                    appInfo.sourceDir = temp;
                    appInfo.publicSourceDir = temp;

                    appicon = appInfo
                            .loadIcon(activity.getPackageManager());
                    mViewHolder.icon.setImageDrawable(appicon);

                } catch (Exception e) {
                    mViewHolder.icon.setImageResource(R.drawable.appicon);
                }

File file = new File(temp + "/" + mDataSource.get(position));

} else if (sub_ext.equalsIgnoreCase("apk")) {

    try {
        Drawable icon = getApk(file);
        mViewHolder.icon.setImageDrawable(icon);

    } catch (Exception e) {
        mViewHolder.icon.setImageResource(R.drawable.appicon);
    }


private Drawable getApk(File file2) {
    try {
        String path = mFileMang.getCurrentDir();
        File file = new File(path);
        String[] list = file.list();

        for (String str : list) {
            String not_installed_apk_file = path + "/" + str;
            PackageManager pm = mContext.getPackageManager();
            PackageInfo pi = pm.getPackageArchiveInfo(
                    not_installed_apk_file, 0);
            if (pi == null)
                continue;
            // the secret are these two lines....
            pi.applicationInfo.sourceDir = not_installed_apk_file;
            pi.applicationInfo.publicSourceDir = not_installed_apk_file;
            //
            res = pi.applicationInfo.loadIcon(pm);
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
    return res;
}
