- Find out the cause of app crash when pressing “BACK” button on “Cocos2dx Activity”.
- Please try if the crash happens on your device
- Please let me know any hint about the cause of the problem
This Android project is created for debugging app crash of cocos2dx activity at pressing BACK button.
This app has "Hybrid” structure with a standard "Android activity" and "Cocos2dx activity". And users can switch both activities using UI and “BACK” navigation button.
I released an app which also has the same “Hybrid” structure but my app user informed me that my app crashes when “BACK” button is pressed. Unfortunately, in my development environment, the crash does not happen every time and cannot find out the cause of the problem from the debug logs.
That’s why I created this simple project which has only simplified activities with almost no functionality to find out the cause of the crash.
- Cocos2d-x 3.15.1 Cocos2d-x 3.16 is the latest version at this moment but it has another problem. So that the app still uses the version 3.15.1
- Android Studio 3.0.1
- Android SDK Build-Tools 27.0.3
- Android TargetSDK 26
- Ubuntu 16.04 LTS
- Classes : C++ files for cocos2d-x
- Resources : images and fonts for cocos2d-x
- cocos2d : modified files for enabling “BACK” button
- proj.android-studio : Android project files
- Clone this project for Android Studio
- Some Cocos2d-x source files have been modified especially for enabling “BACK” button on cocos2d-x activity. The files are saved under cocos2d/cocos folder. Overwrite those files on your project.
- Open “proj.android-studio” folder from Android Studio and build it.
