Consider using CMake or ndk-build integration. For more information, go to: https://d.android.com/r/studio-ui/add-native-code.html Alternatively, you can use the experimental plugin: https://developer.android.com/r/tools/experimental-plugin.html[/code] 
有的说在gradle.properties中添加：

android.useDeprecatedNdk=true


但是也会报错。

正确的修改方式是在build.gradle（Module：app）的buildType上面添加下面一段：

sourceSets {
main {
jni.srcDirs = []
}
}
buildTypes {
、、、
