App crashes on a few older android devices

App crashes on a few older android devices
0

I’m trying to update my game to the cocos2dx 3.17.2. It’s a simple game. The previous release supported >99% of devices with v3.4. The current version works just fine with the vast majority of tested devices using v4.4.2+.

We are getting a few reports of crashes on a few old devices. We have only been able to see what we think is the bug on a Nexus Player running AndriodTV6. The bug has been reported on 4.4.2, 5.1 & 6.

I’m using:
Android Gradle Plugin Version: 3.5.3

Questions:

  1. There are so many variables with these Android builds, is there a reference somewhere of which SDK works best with which cocos version, etc?
  2. Any troubleshooting ideas?

TIA.

You are right. Sadly, Cocos2d-x doesn’t run below Android api 19. I reported the case here: https://github.com/cocos2d/cocos2d-x/issues/20456. I tested this with a newly created project without touching anything.

I have a few device below android 19. Send me an apk to test.

Thanks. Yes, I want to support API 19+. I’ve been experimenting with APIs and NDK’s without luck, however I have narrowed this crash down to asset loading. It’s a “The Fatal signal 11 (SIGSEGV), code 1, fault addr 0x0 in tid 17633 (GLThread 1062)” which happens at asset decompression ZipUtils::inflateToBuffer(). All is fine on the vast majority of devices. I can reproduce this on an old Nexus Player running Android 6. I’m experimenting with preloading assets, or possibly finding local code that can replace the system calls. Any advice is appreciated!
