I upgraded from B4A 6.x to 8.50 and tried to compile and getting the following errors on each file that start with number, such as 1.mp3, 1.png, etc..
why?

java.lang.RuntimeException: Unable to create service takziv.financhick.com.starter: java.lang.RuntimeException: java.io.FileNotFoundException: /storage/emulated/0/Android/data/takziv.financhick.com/files/virtual_assets/1.png: open failed: ENOENT (No such file or directory)

I moved from 6.x to 8.50, so I am unaware of legacy none legacy mode
I am choosing from the drop down (release / debug, ..) so debug

This is not a temporary solution. It disables a debugger optimization. You can safely use it.

@Shay which device are you using? Does it work if you add this line to the manifest editor:
B4X: 
AddPermission(android.permission.WRITE_EXTERNAL_STORAGE)
?

Certainly Erel, but I think that it is not a definitive solution for me, since I would like to return to the situation previous to the recent update of B4A where this command was not necessary in my project. Would it be possible?. Thanks.
