Hi johan, perhaps can you give me a light

, I discovered something interesting. when I open a new project in B4A IDE, and only add this 2 libraries SecretTextView and the FusedLocationProvider
The Compiler say this. apparently we have the same class or jar file twice (I had been reading the forums about this type of errors), I did not really understand 100% where is the conlfict. I did not put any code in the IDE, only the two libraries for test.
something is doind a conflict. perhaps is in Library FusedLocationProvider.
Now why ? RequieresPermission ??
Thanks
Daniel White
