与Android Q中一样，几个WiFi API也受到限制。我正在尝试使用备用API连接到Internet的不同Wifi AP。

下面是我的代码：

    WifiNetworkSpecifier.Builder builder = new WifiNetworkSpecifier.Builder();
    builder.setSsid("wifi-ap-ssid");
    builder.setWpa2Passphrase("wifi-ap-password");

    WifiNetworkSpecifier wifiNetworkSpecifier = builder.build();

    NetworkRequest.Builder networkRequestBuilder1 = new NetworkRequest.Builder();
    networkRequestBuilder1.addTransportType(NetworkCapabilities.TRANSPORT_WIFI);
    networkRequestBuilder1.setNetworkSpecifier(wifiNetworkSpecifier);

    NetworkRequest nr = networkRequestBuilder1.build();
    ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
    cm.requestNetwork(nr, callback);

这使我可以连接，但互联网已禁用。这正在按照Android文档中的定义运行。

我尝试的替代方法如下：

    WifiNetworkSuggestion.Builder wifiNetworkSuggestionBuilder1 = new WifiNetworkSuggestion.Builder();
    wifiNetworkSuggestionBuilder1.setSsid("wifi-ap-ssid");
    wifiNetworkSuggestionBuilder1.setWpa2Passphrase("wifi-ap-password");
    WifiNetworkSuggestion wifiNetworkSuggestion = wifiNetworkSuggestionBuilder1.build();
    List<WifiNetworkSuggestion> list = new ArrayList<>();
    list.add(wifiNetworkSuggestion);
    wifiManager = (WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE);
    wifiManager.removeNetworkSuggestions(new ArrayList<WifiNetworkSuggestion>());
    wifiManager.addNetworkSuggestions(list);

在清单中声明允许：

<uses-permission android:name="android.permission.CHANGE_WIFI_STATE"/>

使用它并没有改变任何行为。

请告知API序列，以成功连接到具有Internet功能的其他Wifi AP。

我目前正在尝试连接到 wifi 网络。我使用了下面的代码。

        WifiNetworkSpecifier specifier = new WifiNetworkSpecifier.Builder()
                .setSsid(ssid)
                .setBssid(MacAddress.fromString(bssid))
                .setWpa2Passphrase(password)
                .build();

        NetworkRequest request = new NetworkRequest.Builder()
                .addTransportType(NetworkCapabilities.TRANSPORT_WIFI)
                .setNetworkSpecifier(specifier)
                .build();

        ConnectivityManager manager = (ConnectivityManager) context.getApplicationContext().getSystemService(Context.CONNECTIVITY_SERVICE);

        manager.requestNetwork(request, new ConnectivityManager.NetworkCallback() {

            @Override
            public void onAvailable(@NonNull Network network) {
                ConnectivityManager.setProcessDefaultNetwork(network);
                super.onAvailable(network);
                NetworkInfo info = manager.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
                if (info != null && info.isConnectedOrConnecting()) {
                    if (!emitter.isDisposed()) {
                        emitter.onSuccess(true);
                    }
                } else {
                    if (!emitter.isDisposed()) {
                        emitter.onError(new RuntimeException("OS Disconnected"));
                    }
                }

            }

            @Override
            public void onUnavailable() {
                super.onUnavailable();
                if (!emitter.isDisposed()) {
                    emitter.onError(new RuntimeException("Could not connect Wifi")); …
