如何在cocos2d-x中使用android ndk检查崩溃日志

Question

我使用cocos2d-x开发游戏,在iOs中运行完美后,我转向Android平台.

但它在android中运行,我只收到一些错误日志:

08-26 10:49:23.823: A/libc(2884): Fatal signal 11 (SIGSEGV) at 0x0000000c (code=1), thread 2917 (Thread-285)

有了这个,我无法修复崩溃日志.

所以我的问题是如何检查崩溃日志的堆栈？

在SO中,有一些类似的问题,但对我没有任何有用的答案.

使用ndk-stack读取崩溃日志

无法从android ndk中的堆栈跟踪中获取行号

如何获得有用的崩溃日志信息Android Cocos2dx C++

Answer 1

我在http://www.cocos2d-x.org/boards/6/topics/20437中找到了完美的答案.

解决方案是:

当你上了logcat的这样的错误,它们将被保存在$PROJECT_PATH/obj/local/armeabi这里$PROJECT_PATH是通向你的cocos2d-X的Android项目.要将消息符号化为可理解的内容,可以使用ndk-stack工具.

打开终端(或Cygwin,但不确定)并输入

cd $ANDROID_NDK
adb logcat | ./ndk-stack -sym $PROJECT_PATH/obj/local/armeabi

哪里:

$ANDROID_NDK 是你的Android NDK的路径

$PROJECT_PATH 是你的cocos2d-x android项目的路径

我尝试了,并得到以下堆栈跟踪:
