java.lang.UnsatisfiedLinkError:dbopen

Question

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)特定的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

可以看看这个并提出建议.

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？

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.调用它的好地方是在Application的派生类中.

请参阅此处的说明

Answer 2

No implementation found for native Linfo/guardianproject/database/sqlcipher/SQLiteDatabase;.dbopen (Ljava/lang/String;I)V
