As mentioned, using acceleratedRendering on an Android device running OS 2.2 or earlier will launch to a black screen if you use the defaults. If you set the compositorType to "software" it works, but I got some unwanted artifacts when I did that. As far as I know it hasn't been fixed yet, so I had to require Android 2.3 or higher. Another thing is incompatibility with 4.1 Jelly Bean. I had to rebuild with 5.5.4 to fix that. Earlier versions of LiveCode apps opened to a black screen on Jelly Bean.
Thanks both, but it doesn't seem to be either of those. I've never used acceleratedRendering, I haven't got that far yet! (and after a careful search have confirmed that no trace of it has crept into my stack). One of my test devices is Android 2.3.4, the other is 4.0.3, but same result on both, including when building from LC 5.5.4.
I did have some success when, in despair, I opened took the "Orientation Example" stack and was able to build that succesfully so that it opened on Android. Then I copied all the elements of my stack into it - and it still worked. So now I have two apparently identical stacks - both one card, the same controls on each, the same scripts in the card and the stack - but one has developed Android-black-screen disease. I've not yet found the critical difference between them.
So I'm thinking that I've stumbled across another way to cause Android-black-screen, which isn't either of the ones you've mentioned (and which happens with the latest test version of LC as well as earlier ones). If anyone knows of any other causes, which I can test to see if that's what's going on here, please let me know. Otherwise (when I've got some time on my hands) I'll try to keep cutting down the problem stack to form a minimal version I can report to RunRev.
