I developed a mobile app for Android and iOS.
Recently, I've come across an android tablet, QM734-8G, that uses Android 4.2.2. When launching the app on this device, I simply get a blank screen and no content is rendered. I know the app is running because when I debug it, I can see all the code executed and traces appearing in the console.
After a lot of testing, I narrowed down the issue; it has to do with the renderMode. The app uses CPU render mode because I don't use any Stage 3D stuff or perform any graphic intensive operations. When I set the render mode to GPU the content does get renreded but I lose the filters (which is a known limitation of GPU rendering) and scrollRect doesn't work as expected. When I set the render mode to DIRECT I can also see the content and this time with filters and everything but the app starts crashing as it seems the memory usage increases in that render mode.
I've done a quick test and created and empty text projetc in Flash Builder and I simply specify the background of the SWF and with that simple test I can replicate the issue, so it's not sometihng specific to the content in my app. I've tested using AIR 3.8 and AIR 3.9.
The tablet has low specs and it's really cheap, but from what I see, the specs are enough to support app deployed usign AIR. Is there something I'm missing?
Please see a screenshot of the device info page.
