本篇文章将跟大家分享一下如何配置ijkplayer的编译脚本，使得我们可以在android studio IDE下调试android端c层的代码。
环境要求
Android studio3.0.1版本 （可以使用其他版本，但是下面的配置就要做相应的改变，但必须是3以上的版本）
Android NDK12+版本 （这个是官网要求的，只有在12+以上才支持c层调试）
操作步骤
-
拉取ijkplayer代码 （git clone https://github.com/Bilibili/ijkplayer.git ijkplayer-android）
-
cd ijkplayer-android
-
git checkout -B latest k0.8.8
-
运行sh android/patch-debugging-with-lldb.sh armv7a，这一步很可能出错，可以改为下列步骤进行:
1). 查看一下patch-debugging-with-lldb.sh文件中需要patch的文件，可以看出对于armv7a来说需要添加的patch有:
android/patches/0001-gitignore-ignore-.externalNativeBuild.patch
android/patches/0002-gradle-upgrade-build-tool-to-2.2.0-beta2.patch
android/patches/0003-armv7a-enable-debugging-with-LLDB.patch
android/patches/0004-armv7a-link-prebuilt-staic-libraries-of-ffmepg.patch
2). 按照patch文件做相应的修改，修改如下（因为版本原因，与ijkplayer提供的修改内容不太一样）：
