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:

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-gdbTo build
Set the
-gcompiler flag in jnk/Android.mk to build the gdb-serverBuild the native lib for debugging
NDK_DEBUG=1Set the application debuggable in the manifest.
Open cygwin and cd to the project path. Set the path to adb.
And then start gdb
You will have to type
continuewhen you have connected to the gdb-server
