如何在Android中使用ssid和密码创建自定义WPA热点? [英] How to create Custom WPA Hotspot with ssid and password in android?

问题描述

我正在使用以下代码创建Wifi热点配置. 我能够创建Hotspot配置并启用它.但是我已经为WPA-PSK提供了配置，但是它始终被视为OPEN网络.

I am using the following code for creating the Wifi-hotspot configuration. I am able to create the Hotspot configuration and able to enable it. but i have give configuration for WPA-PSK, But it always taken as OPEN network.

public boolean setHotSpot(String SSID,String passWord){
Method[] mMethods = mWifiManager.getClass().getDeclaredMethods();

    for(Method mMethod: mMethods){

        if(mMethod.getName().equals("setWifiApEnabled")) {
            WifiConfiguration netConfig = new WifiConfiguration();
             netConfig.SSID = SSID ;
                netConfig.preSharedKey = passWord;
                netConfig.hiddenSSID = true;
                netConfig.status = WifiConfiguration.Status.ENABLED;
                netConfig.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.SHARED);
                netConfig.allowedKeyManagement.set(4);
                netConfig.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
                netConfig.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_EAP);
                netConfig.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);
                netConfig.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
                netConfig.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
                netConfig.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
                netConfig.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
                netConfig.allowedProtocols.set(WifiConfiguration.Protocol.WPA);

            try {              
                mMethod.invoke(mWifiManager, netConfig,true);
                mWifiManager.saveConfiguration();
                return true;

            } catch (Exception e) {
                e.printStackTrace();
                CommonUtil.log(TAG,"Exception : "+e.getLocalizedMessage());
            }
        }
    }
return false; 

}

运行此应用程序后，热点已启用.请检查下面的图像.

After run this app the Hotspot got enabled. Please check the image below.

按照下面的答案，我已经修改了下面的代码.

As per below answer i have modified the code below.

public boolean setHotSpot(String SSID, String passWord) {
    boolean apstatus;
    WifiConfiguration netConfig = new WifiConfiguration();
    if (passWord == "") {
        netConfig.SSID = SSID;
        netConfig.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.OPEN);
        netConfig.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
        netConfig.allowedProtocols.set(WifiConfiguration.Protocol.WPA);
        netConfig.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
    } else {
        netConfig.SSID = SSID;
        netConfig.preSharedKey = passWord;
                /*netConfig.hiddenSSID = true;
                netConfig.status = WifiConfiguration.Status.ENABLED;
                netConfig.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.SHARED);
                netConfig.allowedKeyManagement.set(4);
                netConfig.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
                netConfig.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_EAP);
                netConfig.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);
                netConfig.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
                netConfig.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
                netConfig.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
                netConfig.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
                netConfig.allowedProtocols.set(WifiConfiguration.Protocol.WPA);*/
        netConfig.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.SHARED);
        netConfig.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
        netConfig.allowedProtocols.set(WifiConfiguration.Protocol.WPA);
        netConfig.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
    }

    try {
        Method setWifiApMethod = mWifiManager.getClass().getMethod("setWifiApEnabled", WifiConfiguration.class, boolean.class);
        //setWifiApMethod.invoke(mWifiManager, previousConfigurations, false);
        //Thread.sleep(2000);
        apstatus = (Boolean) setWifiApMethod.invoke(mWifiManager, netConfig, true);
    } catch (Exception e) {
        CommonUtil.log(TAG, e.getMessage());
        return false;
    }
    return apstatus;
}

推荐答案

我已经在我的应用程序中完成了此操作.请在下面检查我的代码.

I have done this in my app. Please check my code below.

首先在清单中添加以下权限.

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

然后在MyHotspotManager .java类下创建

public class MyHotspotManager {
    private WifiConfiguration wifiCon;
    private HotspotDetails hotspotDetails;
    private WifiManager mWifiManager;

    public MyHotspotManager(WifiManager wifiManager){
        this.mWifiManager = wifiManager;
    }

    public boolean setHotspot(HotspotDetails hotspotDetails) {
        this.hotspotDetails = hotspotDetails;
        boolean apstatus;
        wifiCon = new WifiConfiguration();
        wifiCon.SSID = hotspotDetails.getSsid();
        wifiCon.preSharedKey = hotspotDetails.getPassword();
        wifiCon.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.SHARED);
        wifiCon.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
        wifiCon.allowedProtocols.set(WifiConfiguration.Protocol.WPA);
        wifiCon.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
        try {
            Method setWifiApMethod = mWifiManager.getClass().getMethod("setWifiApEnabled", WifiConfiguration.class, boolean.class);
            //setWifiApMethod.invoke(mWifiManager, previousConfigurations, false);
            //Thread.sleep(2000);
            apstatus = (Boolean) setWifiApMethod.invoke(mWifiManager, wifiCon, true);
        } catch (Exception e) {
            Log.e(this.getClass().toString(), "", e);
            return false;
        }

        return apstatus;
    }

}

之后，您可以在活动中的任何位置调用setHotspot方法，如下所示.在这里，我必须检查应用程序是否具有ACTION_MANAGE_WRITE_SETTINGS权限.

public void OnButtonClick(View view) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            if (!Settings.System.canWrite(getApplicationContext())) {
                Toast.makeText(this, "Please try again after giving access to Change system settings", Toast.LENGTH_SHORT).show();
                Intent intent = new Intent(Settings.ACTION_MANAGE_WRITE_SETTINGS, Uri.parse("package:" + getPackageName()));
                startActivityForResult(intent, 200);

            }else{
                createHotspot();
            }
        }

    }

    private void createHotspot(){
        HotspotDetails hotspotDetails = new HotspotDetails();
        hotspotDetails.setSsid("TestStackOverFlow");
        hotspotDetails.setPassword("654321");
        new MyHotspotManager((WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE))
                .setHotspot(hotspotDetails);
    }

但是，如果需要，可以通过将build.gradle中的targetSdkVersion更改为21来省略权限请求部分.现在，您可以按以下方式调用它

    public void OnButtonClick(View view) {
//        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
//            if (!Settings.System.canWrite(getApplicationContext())) {
//                Toast.makeText(this, "Please try again after giving access to Change system settings", Toast.LENGTH_SHORT).show();
//                Intent intent = new Intent(Settings.ACTION_MANAGE_WRITE_SETTINGS, Uri.parse("package:" + getPackageName()));
//                startActivityForResult(intent, 200);
//
//            }else{
//            }
//        }

        createHotspot();
    }

    private void createHotspot(){
        HotspotDetails hotspotDetails = new HotspotDetails();
        hotspotDetails.setSsid("TestStackOverFlow");
        hotspotDetails.setPassword("654321");
        new MyHotspotManager((WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE))
                .setHotspot(hotspotDetails);
    }

这是我的HotspotDetails.java类

public class HotspotDetails {
    private String ssid;
    private String password;

    public String getSsid() {
        return ssid;
    }

    public void setSsid(String ssid) {
        this.ssid = ssid;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    @Override
    public String toString() {
        return ssid + ":" + password;
    }
}
