Multiple File Selection Does Not Work For Android 4.04 and 4.3

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
