Android 4.0.4 showing blank screen

Solar2D Daily Builds and Public Releases
#1

There is an existing problem that was supposed to be fixed in build 894 regarding Android:

“Android: Fixed bug where native objects (TextFields, TextBoxes, WebViews, Ads, Alerts) would turn black and have rendering glitches after switching the screen off/on on some Android 4.0.4 or higher devices. Known to occur on Nexus 7 and Galaxy SIII. case #15600, 16386”

Unfortunately, the bug still exists and happens with any display objects, not necessarily native objects. Try the following with any of the sample code on build 909 or any higher than 894.

  1. Open app
  2. Press power to turn screen off
  3. Press power to turn screen on
  4. Without unlocking, press power to turn screen off
  5. Press power to turn screen on

Images are blank and rendered as a white screen. The event listeners for buttons etc still exist. If the power is cycled once more, the images come back. They will go away again anytime the power is cycled twice as above. Occurs on Galaxy SIII with any app such as DeviceInfo or ShapeTumbler. I admit to becoming frustrated with the number of rendering bugs on Android 4.0.4 and would love to hear confirmation of this experience (outside my two devices) and commentary regarding a solution. It’s possible, not desirable, to live with bugs like the objects drawing outside the screen bounds on resume, but the objects turning alpha to black or disappearing makes Corona apps on Android 4 nearly unusable.

I have the same problem on the Nexus 7. Please fix. [import]uid: 1884 topic_id: 31109 reply_id: 124392[/import]

Based on the steps you mentioned we were able to duplicate the problem on Android 4.04 devices. We were NOT able to reproduce the problem on Nexus 7 running 4.1. This is with build 914. There was a previous issue that affected native objects, which has been fixed. If I run NativeKeyboard2 sample code on an Android 4.04 device with the steps you outlined, the Display Objects are black but the native text fields are visible.

Thanks for the input and we will get this fixed ASAP.
