Debug native c code on android phones

Environment:

CentOS 1, 5.4

[Root @ localhost bin] # cat/etc/redhat-release
CentOS release 5.4 (Final)
[Root @ localhost bin] # uname-
Linux localhost. localdomain 2.6.18-164. el5 #1 SMP Thu Sep 3 03:33:56 EDT 2009 i686 i686 i386 GNU/Linux

VMware 9.0.1 build-894247

I. preparations:

1. Download ndk

Http://dl.google.com/android/ndk/android-ndk-r9c-linux-x86.tar.bz2

2. Download adt

Http://dl.google.com/android/adt/adt-bundle-linux-x86-20131030.zip

Official Website address http://developer.android.com/sdk/index.html

I don't understand what adt is.

Http://blog.csdn.net/aizquan/article/details/8974750

After that, extract the above two items to the virtual machine.

2. Set environment variables and add the following paths to PATH

Android-ndk-r9c
Adt-bundle-linux-x86-20131030/sdk/platform-tools
Adt-bundle-linux-x86-20131030/sdk/tools

3. Run gdbserver on the mobile phone (this step may be difficult to complete)

Push the gdbserver to your mobile phone. Start gdbserver with adb. Pay attention to the version number !!

130 | shell @ android:/$ gdbserver -- version
GNU gdbserver (GDB) 7.3.1-gg2
Copyright (C) 2011 Free Software Foundation, Inc.

Shell @ android:/$ gdbserver 192.168.100.184: 1234/data/test
Process/data/test created; pid = 1877
Listening on port 1234

4. Execute

[Root @ localhost bin] # cd/home/randy/android-ndk-r9c/toolchains/arm-linux-androideabi-4.6/prebuilt/linux-x86/bin
[Root @ localhost bin] #./arm-linux-androideabi-gdb/Mnt/hgfs/CodeBlocks/TTS/arm-linux/test the red part is your executable file (cross-compiled)
