wifiManager.addNetwork(WifiConfiguration);
@Deprecated
public int addNetwork(WifiConfiguration config) {
if (config == null) {
return -1;
}
config.networkId = -1;
return addOrUpdateNetwork(config);
}这是WifiManager.class中addNetwork方法的描述，注意注释中最后一行
{@link android.os.Build.VERSION_CODES#Q} or above, this API will always return {@code -1}.
android Q或者更高的版本，这个方法始终返回-1，至此问题原因分析完毕，接下来开始解决：官网一顿操作：Android 10 的新方案如下连接：https://developer.android.google.cn/guide/topics/connectivity/wifi-bootstrap
代码如下：
public void test()
{
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.Q)
{
NetworkSpecifier specifier =
new WifiNetworkSpecifier.Builder()
.setSsidPattern(new PatternMatcher("此处WiFi名称", PatternMatcher.PATTERN_PREFIX))
.setWpa2Passphrase("此处WiFi密码")
.build();
NetworkRequest request =
new NetworkRequest.Builder()
.addTransportType(NetworkCapabilities.TRANSPORT_WIFI)
.removeCapability(NetworkCapabilities.NET_CAPABILITY_INTERNET)
.setNetworkSpecifier(specifier)
.build();
ConnectivityManager connectivityManager = (ConnectivityManager)
context.getSystemService(Context.CONNECTIVITY_SERVICE);
ConnectivityManager.NetworkCallback networkCallback = new ConnectivityManager.NetworkCallback() {
@Override
public void onAvailable(Network network) {
// do success processing here..
}
@Override
public void onUnavailable() {
// do failure processing here..
}
};
connectivityManager.requestNetwork(request, networkCallback);
// Release the request when done.
// connectivityManager.unregisterNetworkCallback(networkCallback);
}
}注：我用的是WPA的 加密模式，亲测可用。至此完结，撒花。
