(1)ndk-stack 调试命令使用方法
1、在工程目录下的jni文件夹下Application.mk中添加 APP_OPTIM := debug
2、在windows 下使用运行输入 cmd 进入 android-ndk 目录
3、运行命令 adb logcat | ndk-stack -sym d:\documents\project\inferno3\android\obj\local\armeabi\libgame_logic.so
或者adb logcat | ndk-stack -sym d:\documents\project\inferno3\android\obj\local\armeabi查看所有的*.so调试信息
查看文件ndk-native 调试信息

(2)使用模拟器运行Inferno 疯狂城堡额外操作方法
1、使用cmd 进入android-sdk的plafrom-tools目录
2、运行 emulator -partition-size 512 -avd your_avd_name
