B4A Library Android-Water-Gauge

A wrap for this Github project. Download the attached zipped files. Extract LibRes.zip and then copy the folder with its contents to be on the same folder level as that of the /Files and /Objects folders of the B4A project.

Copy the library files to your additional library folder. Also make sure that you have AppCompat V3.51 in your additional library folder and that it is enabled in the IDE library tab
