[问题]菜鸟求助，关于Java+Cpp调试，Android环境

2013/1/22镜像同步5 回复

需要在Android应用中调用Cpp文件处理一些后台数据。在Eclipse+CDT+NDT+JNI+cygWin下进行调试的时候，发现无法进入Cpp代码部分进行调试。 cygwin下的用ndk-gdb命令查看如下 $ ndk-gdb --verbose --force Android NDK installation path: /cygdrive/d/AndroidDev/android-ndk-r8d Using default adb command: /cygdrive/d/AndroidDev/adt-bundle-windows-x86/sdk/platform-tools/adb ADB version found: Android Debug Bridge version 1.0.31 Using ADB flags: Using auto-detected project path: .
