CCLabelTTF - sometimes rendering as black boxes on Android
CCLabelTTF - sometimes rendering as black boxes on Android
Ok,
After tinkering I found the cause of the problem.
I was preparing my CCLabelTTF in applicationWillEnterForeground(). Simply moving the code to a runAction(…callfunc…) fixes the problem.
I don’t know if this is a bug or if the documentation just needs to be updated to warn people that they should schedule the work to be done on resuming the application.

Problem exists with new Label::createFromTTF. If i create a label label like so:
Label::createWithTTF(fontBig,"Example ttf text",TextHAlignment::RIGHT);
I hide app to background (pressing HOME button) and when i re-enter it i get "white boxes".
normal label:
after re-entering:
I think this is caused by not reloading ttfConfig created resources in reloadAllTextures.
This is bad and must be fixed, though i can't deal with this myself :(
Tested Device: Google Nexus 7(2013)
I'm using cocos2d-x ver3.2 and got the same issue, I think...
I'm newbie and I might just be doing something wrong but I'll report.
Is this problem already fixed in the newer versions?
-What I did
Use ui::Text to show some text on the screen (created with Cocos Studio)
Use jni and send an Intent to use the camera with startActivityForResult.
Call a c++ method in onActivityResult passing the path of the photo taken as a string.
Make a new ui::Text and show the path of the photo on the screen.
-What Happens
The ui::Text that was already on screen and the new ui::Text both become black boxes.
-When this problem doesn't occur
For me the problem doesn't occur when I don't do anything when returning from the java side.
(When I just use startActivity instead of startActivityForResult, in which case I can't access the photo...)
-Another situation this problem occurs
The problem also occurs if I try to move to a new scene in the c++ method called from onActivityResult.
Redmine issue system is closed, we are using github issue system instead.

From time to time, if I exit my game on Android while text is being displayed with CCLabelTTF, then when I re-enter the game, the text is replaced with black boxes. I’m guessing the texture is getting lost. All other textures are fine though.
Another way to reproduce the issue:
# start game
# launch some activity (such as an interstitial ad)
# close that activity and return to game
# at this point, have CCLabelTTF display some text ==> here the text is just black boxes
