Bug? [v9.0] Rapid debugger fails to connect on restart

[Computersmith64]

Didn't notice this as an issue with the v9.0 Betas, however since installing the release version this morning I find that if an app is running in debug mode & I click on the Restart button in the B4A IDE, the app fails to restart & I get the "Rapid debugger failed to connect to process" dialog. There is no error in the log.

If I then recompile by clicking the Run or Restart button, the app does a full compile & runs as expected.

On further investigation, it seems that his only happens if the app is restarted without making any changes. If I make a change (I tested by adding a simple Log("Hello") statement to Activity_Create in the Main activity), it restarts OK.

I thought it might just be an issue with one particular project, however I have tested this on multiple different projects & it's the same.

I can confirm same behavior.
If the app is restarted without making any changes I get the "Rapid debugger failed to connect to process. Prease try to run again."

Just for info: I've just tested, but it works ok for me, I can't reproduce the issue.

It doesn't happen here. Does it happen each time when you test it? Does it work properly if you click on the stop button and then on the run button?

Yes it did happen on every restart & with every project I tested it on. It worked properly if I clicked on the stop button & then on the run button (but not if I clicked on the restart button).

Having said that, it now appears to be working correctly. The only difference between when I submitted the bug report & now is that I ran the SDK manager yesterday & downloaded / updated all the packages it recommended - so perhaps there was something in there that resolved the issue?

I don't think that it is related to the SDK version. It seems like a timing issue where the IDE restarts the app too fast, before the app process is killed. I will add a half second delay and see whether it helps. It does happen here from time to time.

That makes sense. I have seen it happen on occasion in the past too, but yesterday it was every time.
