我想以编程方式检测我的双卡Android手机中是否有两张SIM卡.我发现了一个API(TelephonyManager.getSIMState()),但它适用于普通的单SIM卡手机.是否有任何API可以检测我的双卡手机中是否插入了两个SIM卡？
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？
