我的Android的cocos2d-x的遊戲墜毀在一些三星手機，但logcat的沒有顯示出它崩潰

Question

的cocos2d-X採用Android，NDK，我使用了cocos2d-x 2.1.4版，

我用LUA作爲遊戲腳本，我的遊戲會崩潰在一些便宜的手機，如三星s7562c，e120l。遊戲會在不同的地方崩潰。 logcat看起來像下面這樣：

03-26 13:01:18.203: I/DEBUG(106): backtrace:

03-26 10:58:18.135: I/DEBUG(11409): stack: 

我的問題是爲什麼回溯有那麼有意義的信息？

有沒有一些方法可以從ndk崩潰獲得更多信息？

看來，崩潰發生在內存相關的驅動程序，所以我不得不減少遊戲中的內存使用情況？有沒有什麼好的方法來定位這樣的內存問題？ 感謝

這是一個完全轉儲文件：

Answer 1

Error happens in android device driver. These device is shared memory device which seems to be used for cpu and gpu. According to Android OpenGLES document http://developer.android.com/guide/topics/graphics/opengl.html#textures

etc1 format is supported in most android device. So I use this format to compress my game texture. This will save much memory for gpu. I modify cocos2d-x code to make etc1 support alpha channel, according to the below doc. http://malideveloper.arm.com/cn/develop-for-mali/sample-code/etcv1-texture-compression-and-alpha-channels/

有關ETC1更多信息，請查看維基 en.wikipedia.org/wiki/Ericsson_Texture_Compression
