B4J Question Is there a difference between Media Player in Debug Mode and Standalone ?

[Tecuma]

Hello Community,

I build a standalone version of my App with the integrated builder on a Windows 10-x86-64 VM. When I run the App it starts normaly. When I press a button where I play a mp3 file via MediaPlayer it quits without any error message. In the Windows logs I can not see anything.
When I run the App in Debug Mode everything works as expected.

Where is the difference between Media Player in Debug Mode and Standalone?
How can I catch such an error that the App does not quit silently?

Best regards

There are three different modes:
Debug
Release (inside the IDE)
Standalone

I guess that it work properly in release mode, right?

Have you tried to run the standalone package with the run_debug.bat file?

Yes, I mean release mode.

I tried run_debug.bat.

This looks the same as from my other thread where I try my app on Linux.

Is the location from the mp3 file wrong?

It means that it cannot play the file directly while it is packed. You can either copy it at runtime (once) to XUI.DefaultFolder or copy it to the bin folder as part of the packaging process and then play it from File.DirApp.

See tip #5 here: https://www.b4x.com/android/forum/t...-way-to-distribute-standalone-ui-apps.117880/

Thank you for the information and the tip.
How would tip #5 looks for Linux and for macOS?

 

[Erel]

You can copy manually copy the file.
