android - java.lang.UnsatisfiedLinkError : dbopen 错误

Question

我正在尝试在 android 应用程序的代码块上编写 Android 测试用例。该代码块将与数据库(sqlcipher 库函数)交互，特别是 dbopen() 函数。运行应用程序时，它工作正常。当我们试图为该代码块(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调查并提出建议。

测试用例不能有权调用正在调用 sqlcipher 库函数的函数。 是否需要任何权限，或是否有针对此类测试用例的任何特定程序？

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());

Answer 1

我在为 Android 集成 SQLCipher 时遇到了同样的错误。我的解决方案是调用

SQLiteDatabase.loadLibs(Context context)

按照建议，在使用数据库本身之前。在应用程序的派生类中调用它的好地方。
