Android基于JNA加载第三方.so库报错：java.lang.UnsatisfiedLinkError Native library (com/sun/jna/android-aarch64/libjnidispatch.so)

> java.lang.UnsatisfiedLinkError Native library (com/sun/jna/android-aarch64/libjnidispatch.so)

原因是缺失JNA项目所需的Android平台支撑so库。在这里下载对应Android 平台的jar包：

[jna/dist at master · java-native-access/jna · GitHubJava Native Access. Contribute to java-native-access/jna development by creating an account on GitHub.![fluidicon.png][]https://github.com/java-native-access/jna/tree/master/dist][jna_dist at master _ java-native-access_jna _ GitHubJava Native Access. Contribute to java-native-access_jna development by creating an account on GitHub._fluidicon.png_https_github.com_java-native-access_jna_tree_master_dist]

如果是arm64-v8a架构，则选择下载 [android-aarch64.jar][]

![ad7a30245a9a40b2a75abdd2e45c60d6.png][]

把

[android-aarch64.jar][]

解压，里面是一个libjnidispatch.so，把libjnidispatch.so放到Android项目的libs\\arm64-v8a\\里面即可。

注意，此时libs需被设置为jniLibs:
