Android app中可能有很多的.so文件，有时我们不确定这些.so文件都是来源于哪些库的，可以通过在build.gradle中添加代码来统计。具体方法如下：

1.在com.android.application模块的build.gradle文件最后添加如下代码：

// 获取所有的.so文件的打包路径
tasks.whenTaskAdded {task ->if (task.name == 'mergeDebugNativeLibs') {task.doFirst {println("list so files begin")it.inputs.files.each { file ->printSoPath(new File(file.absolutePath))}println("list so files end")}}
}def printSoPath(File file) {if (file != null) {if (file.isDirectory()) {file.listFiles().each {printSoPath(it)}} else if (file.absolutePath.endsWith(".so")) {println "so file: $file.absolutePath"}}
}

注意：
在task.name的if判断时的取值是按照当前启用的productFlavors和Build Variants来确定的，例如：
※当前未设置productFlavors、Build Variants为debug时，取值为：mergeDebugNativeLibs。
※当前未设置productFlavors、Build Variants为release时，取值为：mergeReleaseNativeLibs。
※当前启用的productFlavors为my、Build Variants为debug时，取值为：mergeMyDebugNativeLibs。
※当前启用的productFlavors为my、Build Variants为release时，取值为：mergeMyReleaseNativeLibs。
如果你不确定该怎么写，也可以Rebuild工程，然后在Build选项卡中的输出信息中查找关键字：NativeLibs，看到类似：Task :xxx:merge***NativeLibs的打印，其中merge***NativeLibs就是我们想要的取值。

2.添加完上述代码之后，执行Sync同步工程，然后执行如下任一步骤：
首先Clean Project，然后Run app。
Rebuild Project。
然后观察Build选项卡中的输出信息，会看到类似如下的打印：
 

> Task :app:mergeDebugNativeLibs

如果我们想知道libpl_droidsonroids_gif.so来源于哪个库，通过上述打印，得知其来源于android-gif-drawable库，并且其版本号为1.2.29。我们通过当前工程的依赖树进一步得知，此库的完整名称为：pl.droidsonroids.gif:android-gif-drawable:1.2.29。
