I am to create a shared library for Android OS. Although I have done some Android apps in Eclipse I decided to start my native development with Visual Studio and vs-Android add-on:

http://code.google.com/p/vs-android/

I am really familiar with VS and Google found that add-on as one of the first results. I have gone through the whole setup procedure, installed JDK, NDK, Ant, set system variables and finally got a working project. It works like a charm! But there is a BIG drawback. I am not able to debug the native code.

I know there is NDK-GDB tool, but I am constantly failing when trying to setup it. I have read NDK-GDB.html document, threw away the initial vs-Android solution and successfully gone through the following tutorial:

but now I am stuck again when trying to go through the:

http://mhandroid.wordpress.com/2011/01/23/using-cgdb-with-ndk-debug-and-cgdb-tutorial/

I also tried WinGDB – just imported working Eclipse project containing both native and Java code, but it doesn’t even compile.

In short, there are many pieces of the puzzle, but I am still missing some of them. I am afraid that I am missing the whole idea of debugging code with a command line tool like NDK-GDB is.

Can someone provide me some explanation and clear steps how to debug native libraries (doesn’t matter if with vs-android or Eclipse or whatever else)? Please be aware I am not a Linux guru and also not familiar with cygwin or gdbserver.

    The steps I take to be able to debug using ndk-gdb

    To build

    Set the -g compiler flag in jnk/Android.mk to build the gdb-server 

    LOCAL_CFLAGS := -g

    Build the native lib for debugging NDK_DEBUG=1

    ndk-build NDK_DEBUG=1

    Set the application debuggable in the manifest.

    android:debuggable=true

    Open cygwin and cd to the project path. Set the path to adb.

    export PATH=$PATH:/path_to_android_sdk/platform-tools

    And then start gdb

    ndk-gdb --verbose --adb=adb.exe

    You will have to type continue when you have connected to the gdb-server
