Multiple file selection Android bug or Chrome bug or Something else???

[marsleebrenda]

I have applied jqueryfileupload successfully in a website.
In windows XP /7/vista, I can select multiple files by hitting control key and clicking mouse's left button.

But, in the Android 4.04 and 4.3, I can't find a way to select multiple files.
In android 4.04/4.3 , after hitting "add files", it will pop a list of file pickers in OS such as gallery, file manager, astro,etc.

But none of the file pickers in Andrioid seem to able to select multiple files.

I can select one file, but not multiple files.

I 've tried android Chrome and firefox, and Multi file selection does not work.

The support page shows that multiple-file-selection is supported on Android4+ goggle Chrome

I search all over the web, and multiple file selection on Android seems to depend on file picker.

I tried it with Chrome on Sony Xperia phone (Android 4.3) and Samsung Galaxy Tab 10.1 (Android 4.04) and it doesn't work.

I have used the jQuery-File-Upload demo page to test the multiple file selection, and none of the Android devices can select multiple files. IOS and desktop work great.

According to chromium forum, there seems to a multiple file selection bug in Android Chrome.

I posted it yesterday, but blueimp said it is not reproducible.

Sorry for the long message, and I am completely lost now.

I hope someone familiar with Android and Jquery file upload can answer the following questions:
(If blueimp see it, can you tell me the answer of Question 1 ,2 and 3, thanks!)

Question 1: How can you select multiple file in Android? holding and pressing the picture thumbnail or something else?
Question 2: What file picker you use for selecting files? Astro or Gallery?
Question 3: What's version of Android and the phone model the multiple file selection works?

Thanks!
