I’m getting random crashes in the middle of the game, and I mean
random
, meaning sometimes it happens, sometimes it doesn’t. It also happens at random points in the game. I think it’s memory related.
This is what Eclipse LogCat shows me. I can’t figure out what it means though.
It also sometimes gives me one of the best error messages there is: “debugger committed suicide to free the zombies!”
I’m using cocos2d-x 2.0.4, Eclipse Juno, and Kindle Fire for testing.
Anyone else experiencing this?
I made a bit of a progress and I want to share what I did.
When you get errors like this on the LogCat, they are saved on $PROJECT_PATH/obj/local/armeabi where $PROJECT_PATH is the path to your cocos2d-x android project. To symbolicate the messages to something understandable, you can use the ndk-stack tool.
Open up the Terminal (or Cygwin, not sure though) and type in
cd $ANDROID_NDK
adb logcat | ./ndk-stack -sym $PROJECT_PATH/obj/local/armeabi
where: $ANDROID_NDK is the path to your android NDK PROJECT_PATH is the path to your cocos2d-x android project
After that, you will get a stack trace which points to certain files and line number where the crash occurred. Something like this:
********** Crash dump: **********
Build fingerprint: 'generic/blaze/blaze:2.3.4/GINGERBREAD/6.3.1_user_4107920:user/release-keys'

( more here pointing to cocos2d-x classes )
From the dump above, you can see that on Stack frame #01 points to TowerObj.cpp:150, so I can now go to TowerObj.cpp at line 150 and fix stuff.
Hope this helps.
Additional information
If your Application.mk define that “armeabi”, that link is correct.
$PROJECT_PATH/obj/local/armeabi
But if you define that armeabi-v7s , the correct one is
$PROJECT_PATH/obj/local/armeabi-v7s
Thank you very much, and I also have a question (about logcat out “I/DEBUG”), I use the adb logcat > d: \ log.txt ,after opening It ,it shows like this 60bc66229097a475.png773×472
, how can I be my android application to print out a similar "I/DEBUG log information?
I am facing a similar problem. My code is running for iOS, but not for android.
Here is the crash dump:
