MCPE-17693Force close if Android app backgrounded while loading textures at startup
To reproduce:
1) open Minecraft PE (preferably on a slower device, like the Nexus 7 (2012))
2) immediately after the title screen shows up, press the Multitask button to put Minecraft PE into the background
3) tap on Minecraft PE to bring it back to the foreground
Expected result: MCPE goes back into the foreground
Actual result: MCPE crashes as it tries to access a TextureAtlas that isn't loaded in MinecraftClient::onAppResume

Is this still happening as of 1.0.4.11 (1.0.4 official release) and/or 1.0.6.0 (1.0.6 build 1)?
@SuperGeniusZeb I can't trigger it on 1.2.0b22 on a Nexus 6P anymore, but maybe that device is too fast; I can check on the Nexus 7 again if you want.
Zhuowei Zhang, sorry for taking so long to respond... please do test on the Nexus 7 to see if this issue is still occurring in 1.2.5.52 and/or 1.2.6.2.
Thank you for your report!
