android 编译facebook/fresco图片库

参考 http://www.liaohuqiu.net/cn/posts/about-red-apricot-and-compiling-fresco/

1、准备工作 ，安装ndk 并设置环境变量 ~/.bash_profile
首先要 配置 android_home  和 ndk 环境变量 
记住你下载的ndk版本 后面有用
我下载的是 11

mac 下在 ~/.bash_profile 中配置

export ANDROID_NDK_ROOT=/Users/zhou/Library/Android/NDK
export ANDROID_HOME=/Users/zhou/Library/Android/sdk
export PATH=${PATH}:${ANDROID_HOME}/platform-tools
export PATH=${PATH}:${ANDROID_NDK_ROOT}

保存后 做下  
$source ./bash_profile

或者重启让环境生效

2\下载 fresco 源码 
website : https://github.com/facebook/fresco
https://github.com/facebook/fresco/archive/master.zip

3\解压缩 到自己的工作目录 fresco-master

4\ 进入fresco-master
运行
$./gradlew

就会显示：

BUILD SUCCESSFUL
＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝
各种下载


5\然后在android 中打开此工程 open…
貌似很久 ，我用了一个晚上，如果网速快，会很好，也会各种下载
进行clean project 或者rebuild 或者运行时 会各种报错


============================================
以上只是步骤，以下是遇到的问题
问题 ：

问题1
==========
* What went wrong:
A problem occurred configuring project ':drawee'.
> Failed to notify project evaluation listener.
   > SDK location not found. Define location with sdk.dir in the local.properties file or with an ANDROID_HOME environment variable.
   > SDK location not found. Define location with sdk.dir in the local.properties file or with an ANDROID_HOME environment variable.

解决：
==========
需要设置 android_home 环境变量

问题二 
==========
FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring project ':drawee'.
> Failed to notify project evaluation listener.
   > failed to find Build Tools revision 23.0.0
   > failed to find Build Tools revision 23.0.0

解决：
==========
需要下载build tools 23.0.0 ，不知到为啥要下载这个，更不知道为啥下载不下来

估计是要翻墙，你可以尝试去红杏出墙

或者 用一种智慧的方法 
查看你本地已经安装的 build tools ，但最好要高于 他要求的23.0.0，比如我有23.0.2

那就修改fresco的配置文件
fresco-master/gradle.properties中的BUILD_TOOLS_VERSION
BUILD_TOOLS_VERSION＝23.0.2


问题3
==========
如果 报错中有关于GRADLE_DOWNLOAD_TASK_VERSION 这个的
我把他修改成了
GRADLE_DOWNLOAD_TASK_VERSION=2.1.0
，随便改的 ，当时就过去了
文件位置同上

问题4
==========
FAILURE: Build failed with an exception.


* What went wrong:
Execution failed for task ':imagepipeline:ndk_clean_bitmaps'.
> A problem occurred starting process 'command 'ndk-build''


解决：
==========
需要配置ndk
在imagepipeline中的gradle.properties 中配置
ndk.path=/Users/zhou/Library/Android/NDK


问题5
==========
FAILURE: Build failed with an exception.


* What went wrong:
Execution failed for task ':static-webp:ndk_clean_static-webp'.
> A problem occurred starting process 'command 'ndk-build''


解决：
==========
需要配置ndk
在static-webp中的gradle.properties 中配置
ndk.path=/Users/zhou/Library/Android/NDK


问题6
==========

解决：
==========
这里就要用到刚才配置的ndk ，

根据上面宝错的提示
查看 ndk某目录下 的版本号
/Users/zhou/Library/Android/NDK/toolchains/arm-linux-androideabi-4.9

我的是4.9 ，报错的地方是4.8
在androidstudio 中全局搜索4.8 ，然后替换成4.9

/Users/zhou/Downloads/fresco-master/imagepipeline/src/main/jni/Application.mk 中
NDK_TOOLCHAIN_VERSION := 4.8

/Users/zhou/Downloads/fresco-master/static-webp/src/main/jni
NDK_TOOLCHAIN_VERSION := 4.8

都换成
NDK_TOOLCHAIN_VERSION := 4.9

然后 
重新rebuild
