Android VLC 编译出错处理

错误一：

解决方法：
进入下载的android vlc目录，执行以下指令：
# cd vlc
# git reset --hard origin
# git pull origin master
# git checkout -b android ${TESTED_HASH}
# git am ../patches/*

注：在老的git版本中git checkout并没有-B的选项，所以一开始执行的时候并没有下载android版本的vlc代码，故使用git checkout -b android ${TESTED_HASH}。



错误二：

出错信息：
BUILD FAILED
/usr/local/android-sdk-linux/tools/ant/build.xml:517: Unable to resolve project target 'android-15'

Total time: 3 seconds
make: *** [vlc-android/bin/VLC-debug.apk] Error 1
rm android-libs/libmedia.c android-libs/libutils.c android-libs/libstagefright.c android-libs/libbinder.c


解决方法：
进入到android-sdk-linux/tools目录，执行“./android“，下载Android 4.0.3（API15）相关文件。

解决方法：
在ie栏中直接输入“”（会开始下载你所需要的文件），然后将相应下载的压缩文件存放于contrib/tarballs/目录下，将名字改成speex-git.tar.gz。若碰到其它的库文件有类似的错误，可采用该办法。
