我正在尝试更新数据库中存在的位置。该位置以包含城市ID和城市名称的城市数组列表的形式存储。我正在尝试让应用知道位置。如果用户位置发生更改，则从Home Frame Activity的onCreate（）方法调用此函数。如果您可以看一下这段代码，并让我知道这是否是更新数据库的过程，或者是否需要进行任何代码更改，那就太好了。到目前为止，即使在检测到用户的当前城市（不同于用户注册的城市）并使用此功能更新数据库中的城市之后，不同的API（如callGeneralListAPI，callConnectAPI等）仍使用旧的城市ID。
我已经附上了日志文件的屏幕快照，该屏幕快照显示即使检索了当前城市（加尔各答市ID 7），不同的API仍使用孟买的旧城市ID（城市ID 1）。
如果我在这里缺少某些代码逻辑，请告诉我。
帮助将不胜感激。

最佳答案
我认为您应该通过以下调试过程。
如果可能，请回应RequestHandler.getInstance().postWithHeader(this,getString(R.string.baseurl) + getString(R.string.settings), locationChange,this, AppConstants.ApiRequestCodeKey.SAVE_APP_SETTINGS
操作成功或失败。如果失败，那么问题就在那里。如果成功的话
检查它在哪里保存值，实际上是否在更改所需的值（我想它没有更改）。如果没有改变，那么问题就出在这里。但是如果改变，
检查其他API调用从何处获取此值。
