错误:带有roboelectric和realm的java.lang.UnsatisfiedLinkError

问题描述

我正在为应用程序使用realm数据库，并使用roboelectric单元测试框架来执行单元测试.我看到realm是用本机c代码编写的，它具有librealm-jni.so文件用于其功能.

Hi I am using realm database for my application and using roboelectric unit testing framework for performing unit testing. I see realm is written in native c code, it has librealm-jni.so file for their functionality.

我收到UnsatisfiedLinkError错误，在robolectric不支持本机库的地方阅读.我相信必须有某种方法来解决它.我尝试了此如何在使用Robolectric时加载.so的可接受答案.但没有运气.

I am getting UnsatisfiedLinkError error, read somewhere that robolectric does not support native libraries. I believe that there must be some way to resolve it. I tried accepted answer of this How to load .so when using Robolectric? but no luck.

选中此退出

Realm不支持Robolectric是一个未解决的问题.

It is an open issue that Realm doesn't support Robolectric (yet).
