so文件相关

2018-08-31

今天尝试了一下编译so文件。

最开始是按照这个博主来操作的https://blog.csdn.net/tianshuai4317618/article/details/79073836

后来我的Android Studio (v3.1.3)说这种方式不再支持了，叫我换CMake。

然后我就换CMake了，可是一直报这个错

一直以为要配置什么变量，就去学CMakeLists.txt的语法，也没找到那个变量，不了了之了。

天无绝人之路，后来我碰运气，打到了解决办法

感谢博主https://blog.csdn.net/qq_36630050/article/details/80708685

我以前的ndk是17的，我按他说的改为ndk 16的就好了。

今天打aar模块包的时候，不知道为什么，so文件没有打包进去，我是手动加进去的。好奇怪，导出aar没有包括so文件。

原因是我依赖了一个其它的第三方动态库so，但是我把那个so加进apk直接闪退，晕，如果把那个依赖库去掉就ok了。

用别人打好的so包。如果是

System.loadLibrary("swresample");//导入生成的链接库文件
System.loadLibrary("avcodec");//导入生成的链接库文件
System.loadLibrary("avutil");//导入生成的链接库文件

这样的顺序，就会报上面的错误 ：

正确的写法是

System.loadLibrary("avutil");//导入生成的链接库文件
System.loadLibrary("swresample");//导入生成的链接库文件
System.loadLibrary("avcodec");//导入生成的链接库文件

。不过后来我自己打的包，却没这个限制。

这个是我启用了ndk编译后，没有找到对应的架包造成的，就是ndk打出来的是全平台的，而第三方SDK只是指定平台的。所以要在build.gradle加上

android{
    defaultConfig {
          ndk{
                abiFilters "armeabi"
           }
    }
}

指定只打包armeabi平台的。

如果加了还是会有，“就清缓存” 。build\intermediates\cmake，这里面的删除了。我的就是多了一个arm64-v8a平台。
