Android Question Help! java.lang.RuntimeException: Unable to create service

[juacochero]

Hi everyone!
Sorry to bother you with this, but I'm now getting this error whenever I start my app.
It did not do it yesterday, nothing changed (except I updated to v7.30), and it doesn't do it everytime I run the app (but most times):
Any ideas?
Thank you!

Is it possible to hook into a device running the app in debug mode to get more info? Secondly, the crash if involving a SocketException. It's something to do with your Socket connection failing and crashing the app. You may need a try and catch statement somewhere.

Also try move the connectioncode (init, open) to the Service_Start sub.

But the best would be if you create a small test project which shows the issue. Upload this project. File-Export as Zip

This error happens when you install a debug version and it is restarted. This often happens with widgets.

The solution is simple. Install your app in release mode.

Thank you Erel! That seemed to do the trick!

Thank you Erel! That seemed to do the trick!

I have this happen a lot with one of my larger apps with the emulator (not a widget) and is very annoying.
You can also solve the problem by reverting to using the legacy debugger (Tools > IDE Options > Use Legacy Debugger) or restart B4A.
