问题
I downloaded a simple demo for Dropbox Chooser & it works fine for me, but how can I set the file type for chooser same as for JS Chooser?
JavaScript is able to set file type for chooser like so:
set options param with extensions: ['.pdf', '.doc', '.docx']
回答1:
The Chooser on Android doesn't support file extension filtering.
