无法在诺基亚S60上检索CELL-id和LAC在E50中试用

编程问答 2022-04-26

问题描述

我一直在尝试获取celllid，lac，mcc和mnc。虽然可以找到mcc和mnc，但cell-id和lac仍然为null。这是代码（众所周知，它根据正在进行的线程数工作，但我仍然无法使它工作）

} 我从这里获取了代码（我现在希望它在nokia e50上运行，因此使用了com.nokia.mid.cellid（事实上，我也尝试过此链接上提到的所有其他选项））Cellid和lac都返回当正确返回mcc和mnc时为null。     

解决方法

        我确认无法从E50收到单元ID。但是我已经写了一种多平台解决方案，我将在广泛的设备（我们的生产环境中> 1000个设备）上对此进行检查。我从相同的链接获得了原型，但是老实说-编写它的人并没有透露细节。 我非常怀疑我的代码能否在至少一半的设备上运行，但是无论如何我们很快就会看到它。
