Bug? Not stopping at breakpoint in debug mode

[Tim Chapman]

Breakpoints have worked on my project in the past, but are not now. My project is large and requires external files in File.DirRootExternal. I would be happy to use teamviewer to help troubleshoot this.

Check the unfiltered logs. Are there any error messages?

Does it break if there is a breakpoint in Activity_Create of the main activity?

 

[Tim Chapman]

It does not break on breakpoint in Activity_Create of the main activity.

Latest unfiltered logs are here:

Are you using the legacy debugger? Uncheck Tools - IDE Options - Use legacy debugger.

 

[Tim Chapman]

I unchecked use legacy debugger. Still no break for breakpoint in Activity_Create.

It looks like a network issue. Have you tried it with a different device?

 

[Tim Chapman]

I have tried it on the latest Nexus 7 2013 32gb device and my galaxy note s3 phone. Both skip the breakpoint.

 

[Tim Chapman]

Now also, when there is an error in my code, the app crashes instead of showing the error location with the yellow line in the code. So, I switched to the legacy debugger. With that, the yellow line appears in the code when there is an error and I can hover over variables to see their values. It still skips the breakpoint when using either debugger.

 

[Erel]

the app crashes instead of showing the error location with the yellow line in the code

This is the expected behavior. It should crash and show the error message in the logs.

If you like you can send me the project. As it doesn't stop on the first line, there is no need to send any other file.

I've ran your program with B4A-Bridge with a breakpoint set in line 106. It did pause.

Are you using B4A v6.80?

 

[Erel]

Have you tried to debug other applications (only with the non-legacy debugger)?

 

[Tim Chapman]

I tried the DialogsDemo in non-legacy mode. It stopped at a breakpoint in Activity_Create with no problem.

 

[Tim Chapman]

I just tried a breakpoint in legacy debug mode on my project and it worked. I found that I have to have the breakpoint on a line of code. It can't be between lines of code. Did not know that. Might have done this wrong before.
I also just tried the same breakpoint using non-legacy debug mode. Worked properly and gave me the yellow line and variables to hover over. Sorry if I caused a problem here. I might have had a breakpoint on a blank line between code before. I don't remember.

Erel,
this looks like the same problem I've been dealing with for over a year.
I can not compile with breakpoints set...
Regards,
Rusty
