崩溃似乎与WiFi有关，但是Android模拟器无论如何都不应该支持WiFi.这里可能是什么问题?

It seems that crash is somehow related to WiFi, but Android emulator shouldn't have WiFi support anyway. What could be the issue here?

推荐答案

我设法自己修复了它.问题似乎是由于com.android.settings.wfd.WifiDisplaySettings.isAvailable报告WiFi可用，而wifip2p服务不存在.我去了WifiDisplaySettings.java:216并将此检查替换为false，因此它不会尝试查找服务.现在可以正确打开设置.

I managed to fix it myself. The problem seems to be due to com.android.settings.wfd.WifiDisplaySettings.isAvailable reporting that WiFi is available, while wifip2p service is absent. I went to WifiDisplaySettings.java:216 and replaced this check with false, so it won't try to locate the service. Now Settings can be opened properly.
