Android Question Error On Compile

[RichardN]

I am returning to a previously good project I have not touched for a few weeks. At the first attempt to compile I get:

B4A Version: 8.50
Parsing code. (0.03s)
Building folders structure. (0.08s)
Compiling code. (0.09s)

Project uses Dialogs Library 2.92. Any ideas as to the cause?

You should upgrade to the latest version of the Dialogs library: https://www.b4x.com/android/forum/threads/dialogs-library.6776/#content

However this error probably happens because you are using old build tools. Follow the installation instructions and make sure to start with a new folder: https://www.b4x.com/b4a.html#installation
