Import and Export on Android

[Ray]

Greetings,

Could anybody help me importing and exporting data on an Android phone?  
I can't even load the clipboard with;

    set the clipboardData["text"] to myData

It works within my app but if I move over to Memo or Google Sheets it's 
just not there.

Ideally I'd like to be able to write text files to a folder I create, or 
even better, write a file which I can send via Bluetooth or put in a 
Dropbox account.

Any ideas?

Many Thanks!
