我正在尝试在android应用程序的代码块上编写一个Android测试用例。该代码块将与数据库（sqlcipher库函数）进行交互，具体为dbopen（）函数。运行应用程序时，它工作正常。当我们尝试为该代码块执行测试用例时（涉及数据库交互）。它给出以下错误：java.lang.UnsatisfiedLinkError：dbopen
可以看看并建议。
测试用例无权调用调用sqlcipher库函数的函数。 是否需要任何权限，或者此类测试用例是否有任何特定的过程？

代码：
测试用例中的下面一行是间接调用sqlcipher库函数。
ApplicationController.getInstance（）startDatabase（this.getContext（）getApplicationContext（））;

我在为Android安装SQLCipher时遇到了同样的错误。我的解决方案是打电话
SQLiteDatabase.loadLibs(Context context)
在按照建议使用数据库本身之前。在Application的派生类中调用它的好地方。

这个“不满意链接”错误可能是由于已经加载了一个类，而是由运行时类加载器层次结构中的错误类加载器引起的。
通常的猜测是Sqllite包存在于Classpath中，但是在运行测试的场景中，错误的加载器实例已经加载了数据包。
