Android调试本机代码

Question

我正在使用ndk-r9，我正在努力让ndk-gdb为我工作。我开始了一个名为“LittlestAndroid”的小型Android应用程序，它可以简单地调用返回硬编码字符串的本地C++方法。该应用程序构建/安装/运行得很好。现在我正在重新调整应用程序以了解ndk-gdb。我在清单中设置了debuggable =“true”。我已经设定这些ENV在我的化妆瓦尔：

APP_OPTIM=debug 
LOCAL_CFLAGS := -g 

，我已经破解了$ NDK_HOME /编译/核心/ build-binary.mk文件使用有条件剥离调试符号如下：

$(LOCAL_INSTALLED): $(LOCAL_BUILT_MODULE) clean-installed-binaries 
    @$(HOST_ECHO) "Install  : $(PRIVATE_NAME) => $(call pretty-dir,$(PRIVATE_DST))" 
    $(hide) $(call host-install,$(PRIVATE_SRC),$(PRIVATE_DST)) 
# $(hide) $(PRIVATE_STRIP_CMD) 
# CCC Modifications start 
ifneq ($(APP_OPTIM),debug) 
    @ $(HOST_ECHO) "Stripping the library for the release mode....." 
    $(hide) $(PRIVATE_STRIP_CMD) 
endif 
# CCC Modifications end 
#$(hide) $(PRIVATE_OBJCOPY_CMD) 

$(call generate-file-dir,$(LOCAL_INSTALLED)) 

endif 

当我尝试调试对抗模拟器我得到这个：

~/workspace/LittlestAndroid$ ndk-gdb -s emulator-5554 --start 
java.io.IOException: handshake failed - connection prematurally closed

辞职，并试图再次GDB连接（无需点击“强制关闭”在模拟器上）我得到这个后：

(gdb) c 
Continuing. 

我错过了什么或做错了什么？在这两种情况下，我都无法让调试器连接和/或继续执行我的应用程序。我也试着开始NDK-GDB后设置断点，但我得到以下几点：

(gdb) b libs/info.cpp:7 
No symbol table is loaded. Use the "file" command. 
Make breakpoint pending on future shared library load? (y or [n]) y 
Breakpoint 1 (libs/info.cpp:7) pending. 
(gdb) 

有没有人成功运行NDK-gdb的，如果这样你可以提供指导？我已经搜遍了所有的东西，但除了最基本的教程之外我什么都没发现，没有深入的解释如何真正设置断点（如上所述，我是否使用相对路径指向我的cpp，或者只是指出文件基本名称？解决我所看到的错误。

UPDATE 我刚刚发现this question这似乎表明在NDK-R9的问题。我会下载一个较早的版本并给它一个镜头。

Answer 1

是的，最新的ndk-r9调试工具确实存在问题。降级至修订版8e后，所有内容似乎都能像广告一样工作。

更新

我只是尝试了最新9D NDK和问题依然存在，虽然错误是稍有不同。我试图在运行4.4的摩托罗拉G上调试我的应用程序，调试器抛出一个套接字错误，试图建立连接。

第二次更新 我在想这个古老的问题，想知道NDK是否与特定操作系统有亲和力。换句话说，最新的NDK版本是否适用于以后的操作系统？我在4.4上试过V9，但失败了，但是9会在5.0或5.5上运行？食物的思考...
