Answer 1

在清单中指定位置权限是不够的，您还需要实际请求它（就像您对WRITE_EXTERNAL_STORAGE和READ_PHONE_STATE的那样）。 这就是您在日志中看到SecurityException: UID 10293 has no location permission的原因。

您偶然发现的确实是 Android 10 中的新内容。 请注意，这只是一个记录在此处的错误。 您的应用不应崩溃，它只会从getConfiguredNetworks接收到一个空列表（并打印这些日志）。

但是，一旦您成功请求权限，您可能最终会被下一次检查捕获（除非您的应用程序是运营商应用程序）。 因此，您可能需要重新考虑是否要以 API 29 为目标（从长远来看不现实）或考虑其他解决方案来实现您的功能。
