android - 以编程方式连接到它时 Wifi Internet 无法正常工作 android>=10

Question

我正在尝试在 android 中以编程方式连接到 Wifi，但问题是 wifi 正在连接，但互联网无法正常工作，虽然 wifi 有互联网但在应用程序上它不工作。当我尝试添加 NET_CAP_INTERNET 时，它会捕获块而不是连接到 wifi。我有oneplus手机，在其他一些手机中我也面临这个问题。我也尝试添加 NET_CAP_NO_RESTRICTION 但问题仍然存在。帮我解决这个问题。

同样对于低于 10 的 android，因为我们没有任何回调，所以我们怎么知道用户输入了错误的密码。就像当用户输入错误的密码时我们需要做一些事情一样。我们应该怎么做？

                wifiConfig.SSID = "\"" + ssid + "\"";
                wifiConfig.preSharedKey = "\"" + password + "\"";
                int netId = wifiManager.addNetwork(wifiConfig);
                wifiManager.enableNetwork(netId, true);
