The SDL forums have moved to discourse.libsdl.org.

Hi,

I have been using SDL2 for android with my apps/games.
It runs perfectly until 2 weeks ago when I had the latest build.

Today I updated the SDL from the 'http://hg.libsdl.org' and I build it.
It compiles fine but as soon as I run my app on my tablet I get this weird problem:
1) The app does not crash but shows a black screen when it should show the app.
2) There is no error in the logs.

What is it? Can you imaging?
Which change ij the last 2-3 weeks could have triggered this?

Thanks
Giorgos

Difficult to say... however there's a tool built into hg to troubleshoot this very problem.

All you need to do is pick a revision from 2 weeks ago which works and set that as the "good" revision, set the current head as the "bad" revision, and keep building/testing until you isolate which revision introduced the problem. If you can tell us this revision, we'd have a much better chance at suggesting a course of action.

It looks like I had old object files laying around.  With a clean build everything works correctly.
