I confirm it success download the files and save it on :
code: 
INTENT URI: content:///storage/emulated/0/Download/Laporan Transaksi Member.xlsx

I think it must use file sharring or something copy it to serviceprovider shared folder ?

Click to expand...
and more confusing, if run on debug mode it can catch download, on release mode it not catch anything, as I run Your code (release mode) and that run well on my code (on debug mode) if I change my app to release , nothing happen with click export button. Log show :
code: 
*** Service (starter) Create ***

** Activity (main) Create (first time) **

The logs shows this is not my code.

It open B4xMainPage with blank n button bellow. click button on first b4xmainpage, it show report page, that load web link .
Click to expand...
This is expected. The WebView already moved from B4XMainPage layout to a new B4XPage layout as you wished.
B4XMainPage only has a button to open the new Page.
The new B4XPage has a WebView that loads the url.

Sorry, I don't want to help anymore and work with people with such attitude.

code: 
*** Receiver (firebasemessaging) Receive (first time) ***
*** Receiver (httputils2service) Receive (first time) ***
:frmbrowser,18
and this part obbiously from my project log, I has inspected your code and even not enable #BridgeLogger, there for log pure from java log bellow. And last but not least :
I never modified your sample code , I run as it is and honestly show log file to you, if it has mistaken copy and paste , mix with my project log because I trial some other B4A project windows code with enable #BridgeLogger, Im sorry for that U think I dishonest. Thats not on purpose.
