以编程方式连接到程序的热点

Question

在我的课程中有两种能力

1. 创建热点
2. 连接到此热点

我在两个不同的设备上安装此程序。三星gallaxyS2和HTC oneM8。创建热点没有问题。如果我在三星gallaxyS2上创建热点，我可以轻松连接到HTC oneM8，但如果我在HTC oneM8上创建热点并尝试连接三星gallaxyM8，则addNetwork函数返回-1。 这是我的连接代码：

private void JoinToNetWork(){
    ScanResult AP= scanAP();
    if (AP!=null){
        try{
            txt.setText("Hotspot named ''" + AP.SSID +"'' is found !  \n");
            wConfig=new WifiConfiguration();
            wConfig.SSID=AP.SSID;
            wConfig.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
            wConfig.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
            wConfig.allowedProtocols.set(WifiConfiguration.Protocol.WPA);
            wConfig.allowedAuthAlgorithms.clear();
            wConfig.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
            wConfig.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
            wConfig.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP40);
            wConfig.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP104);
            wConfig.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
            wConfig.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);
            int NetId=wfMgr.addNetwork(wConfig);
            try{
                txt.append("Disconnect : " + wfMgr.disconnect() +"\n");
                txt.append("Enabling network ... " + wfMgr.enableNetwork(NetId, true) + "\n");
                txt.append("Reconnect to " + AP.BSSID + "/" + AP.SSID + ".... " + wfMgr.reconnect() + "\n");
                wfMgr.setWifiEnabled(true);
                txt.append("connected");
            }catch(Exception e){
                txt.setText(e.toString());
            }
        }catch(Exception e){
            Toast.makeText(this.getBaseContext(), e.getMessage()+"..."+e.toString(),Toast.LENGTH_LONG).show();
        }
    }else 
        Toast.makeText(this.getBaseContext(), "There is no BluffGame AccessPoint",Toast.LENGTH_LONG).show();
}
