ANRs in Google's developer console for some old devices

cocos2d-x C++
#1

I have a bunch of ANRs in Google’s developer console, they are grouped under “ANR Broadcast of Intent { act=android.intent.action.SCREEN_OFF flg=0x40000000 }”. They are typically occurring on some old devices (S5360, S5570, etc). They occur rarely, I see thousands of users of S5360 and S5570 in statistics, but only 20-30 ANRs each day for those devices.

The problem is that there are many 1-star ratings from those unhappy users with ANRs. But I do not want to remove S5360 and S5570 from the list of supported devices on Google Play, because they are working fine for many users.

Does anybody have any ideas on how to fix those ANRs? I’m not expert in cocos2dx internals, but why SCREEN_OFF may sometimes cause “Application not responding” dialog? As I know, SCREEN_OFF is sent when user turns off the device. I’m unable to reproduce the problem on my Android devices.

Below is a typical ANR report from my Google’s developer console:

Yeah I had the same problem with Arrow Mania. My 4 sprite sheets were 1024x2048 pixels. Basically, the phone couldn’t handle it. I halved all sprite sheets and detected lower res phones and made my game run that way (wasn’t too hard as I already did that for iOS retina and non-retina phones).

It is well worth doing, most of India, Spain, eastern Europe, etc players are using these phones. In my Google Analytics two models of Galaxy Y are 3rd and 6th most popular devices.

The other thing to look out for is to make sure you are using 2.1.5 Cocos2D-x, there was also a problem with CocosDension on a number of phones like the S2 and Galaxy Y, and a black screen problem, both have now been fixed.

I’m also using smaller images for low-res screens, but ANRs are still occurring. Do you mean that with Cocos2dx 2.1.5 you have no SCREEN_OFF ANRs in developer console? I’m still using Cocos2dx 2.0.4, because it works fine for me, the only problem is ANRs.
