【问题描述】：
我正在尝试在 android 应用程序中的代码块上编写 Android 测试用例。代码块将与数据库（sqlcipher 库函数）特别是 dbopen() 函数进行交互。运行应用程序时，它工作正常。当我们尝试为该代码块（涉及数据库交互）执行测试用例时。它给出以下错误：java.lang.UnsatisfiedLinkError: dbopen
任何人都可以对此进行研究并提出建议。
测试用例不能有权调用正在调用 sqlcipher 库函数的函数。 需要任何权限，或者这种类型的测试用例是否有任何特定的程序？

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());
【问题讨论】：
-
可能你正试图获取已经可读/可写的数据库副本的可读/可写。
-
您找到解决方案了吗？您已将以下答案检查为“解决了问题”，但它并没有真正说明该怎么做。
