在奥利奥(8.1.0)上，未获得正确的Wifi SSID.显示< unknown ssid>虽然它已连接到具有SSID的wifi [英] On Oreo (8.1.0) not getting the correct Wifi SSID. It's showing <unknown ssid> though it is connected to a wifi with SSID

问题描述

我需要检查android上当前连接的wifi SSID.我分别使用诺基亚6和OnePlus 5以及奥利奥8.1.0和奥利奥8.0进行了检查.其他具有不同操作系统版本的手机可以与此代码一起正常工作.我的代码有什么问题吗?

private WifiInfo wifiInfo;
private String ssid = "";
private WifiManager wifiManager;

private boolean getWifiStatus() {
    wifiManager= (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
    wifiInfo = wifiManager.getConnectionInfo();
    ssid = "";
    ssid = wifiInfo.getSSID();
    ConnectivityManager cm =
            (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
    boolean isWiFi = false;
    if(activeNetwork != null){
        isWiFi = activeNetwork.getType() == ConnectivityManager.TYPE_WIFI;
    }

    Log.d(TAG, "getWifiStatus: " + ssid);
    if(ssid.contains("TripleMZim") && wifiManager.isWifiEnabled() && isWiFi ){
        return true;
    }
    else{
        return false;
    }
}

清单文件中的权限:

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.INTERNET"/>

解决方案

Oreo 8.1+设备需要粗略的位置运行时权限以及需要打开的位置服务，才能检索连接的SSID，因为它可以推断用户位置.

I need to check the current connected wifi SSID on android. I checked with Nokia 6 and OnePlus 5 with respectively Oreo 8.1.0 and Oreo 8.0. Other phones with different OS version is working fine with this code. Is there anything wrong with my code?

private WifiInfo wifiInfo;
private String ssid = "";
private WifiManager wifiManager;

private boolean getWifiStatus() {
    wifiManager= (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
    wifiInfo = wifiManager.getConnectionInfo();
    ssid = "";
    ssid = wifiInfo.getSSID();
    ConnectivityManager cm =
            (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
    boolean isWiFi = false;
    if(activeNetwork != null){
        isWiFi = activeNetwork.getType() == ConnectivityManager.TYPE_WIFI;
    }

    Log.d(TAG, "getWifiStatus: " + ssid);
    if(ssid.contains("TripleMZim") && wifiManager.isWifiEnabled() && isWiFi ){
        return true;
    }
    else{
        return false;
    }
}

permission in Manifest file:

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.INTERNET"/>

解决方案

Oreo 8.1+ devices require the coarse location runtime permission as well as location services to be turned on before being able to retrieve the connected SSID as it can infer the users location.
