Is there a font file?

Caused by: java.lang.RuntimeException: Font asset not found fonts/digital-7_mono.ttf

I downloaded and copied a file with that name to Files/fonts the demo compiles but without any logs (from an emulator) says "unfortunately, digit has stopped!" no other error!?

Thanks

Attached is the 2 .ttf files. Make a folder called fonts inside the /Files folder of your B4A project and then copy the attached 2 files to be inside the fonts folder

tried with your files, that where the same as my files, in the same location and same result! no log output (on my emulator) runs, then message "Unfortunately, b4aDigitSpeedView has stopped!"

Try and run with only of the two indicators on the emulator and see if it runs (i.e juts try with dsv1 and comment out everything related to dsv2)

That works, but i wanted 3 of them, Im now using a gauge "Velocimeter"from donmanfred, but that now seems to have issues!

Thanks
