回答1:

Well you can scrape the playstore app page for a given app and get the permissions it needs :)

Well that's just off the top of my head. On a serious note, you can do the following:

Intent intent = new Intent(Intent.ACTION_MAIN, null);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
List appsList = getPackageManager().queryIntentActivities(intent, 0);

for (Object app : appsList) {
    ResolveInfo resolveInfo = (ResolveInfo) app;
    PackageInfo packageInfo = null;
    try {
        packageInfo = getPackageManager().getPackageInfo(resolveInfo.activityInfo.packageName, PackageManager.GET_PERMISSIONS);
    } catch (NameNotFoundException ex) {
        ex.printStackTrace();
    }

    String[] requestedPermissions = packageInfo.requestedPermissions;
}
