एंड्रॉयड: प्रोग्राम

Question

मैं पोर्टेबल WiFi हॉटस्पॉट पर चालू करने के लिए कोशिश कर रहा हूँ, इस लिंक का हवाला देते हुए WiFi हॉटस्पॉट को चालू करें:।
how to set advanced settings of android wifihotspot

यह सैमसंग गैलेक्सी एस 3 एंड्रॉयड v4.4.2 पर अच्छी तरह से काम कर रहा है (कोई मुद्दों)
लेकिन समान या निम्न एंड्रॉइड संस्करण वाले अन्य उपकरणों पर, एप्लिकेशन क्रैश और डिवाइस को पुनरारंभ करता है।

इस प्रकार मैं निम्नलिखित प्रश्न हैं:

• मुझे पता है क्यों इस एप्लिकेशन सैमसंग S3 पर लेकिन अन्य उपकरणों पर नहीं सामान्य रूप से बर्ताव कर रही है चाहते हैं?
  
• मैं इस समस्या को कैसे ठीक कर सकता हूं?

Answer 1

मुझे एक ही समस्या थी। आपको निम्नलिखित कोड लाइन को मिटाना होगा:

netConfig.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);  

यह संस्करण 4.1.1, 4.2 और 4.3 में मेरे लिए काम करता है।

 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(); 
       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.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP); 
       netConfig.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP); 
       netConfig.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK); 
       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,false); 
        mWifiManager.saveConfiguration(); 
        return true; 

       } catch (Exception e) { 
        e.getMessage(); 
       } 
      } 
     } 
     return false; 
    } 

सम्मिलित AndroidManifest में इस अनुमति:

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

Answer 2

एंड्रॉयड 5.0.1 में इस कोड मैं परीक्षण की कोशिश करो गुप्त कुंजी।

 netConfig.preSharedKey = "testPassword"; 
     netConfig.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK); 

अन्यथा यह डिवाइस को क्रैश और पुनरारंभ करेगा।

Answer 3

WifiConfiguration netConfig = new WifiConfiguration(); 

netConfig.SSID = "MyAP"; 
netConfig.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.OPEN); 
netConfig.allowedProtocols.set(WifiConfiguration.Protocol.RSN); 
netConfig.allowedProtocols.set(WifiConfiguration.Protocol.WPA); 
netConfig.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE); 

try { 
    Method setWifiApMethod = wifiManager.getClass().getMethod("setWifiApEnabled", WifiConfiguration.class, boolean.class); 
    boolean apstatus=(Boolean) setWifiApMethod.invoke(wifiManager, netConfig,true); 

    Method isWifiApEnabledmethod = wifiManager.getClass().getMethod("isWifiApEnabled"); 
    while(!(Boolean)isWifiApEnabledmethod.invoke(wifiManager)){}; 
    Method getWifiApStateMethod = wifiManager.getClass().getMethod("getWifiApState"); 
    int apstate=(Integer)getWifiApStateMethod.invoke(wifiManager); 
    Method getWifiApConfigurationMethod = wifiManager.getClass().getMethod("getWifiApConfiguration"); 
    netConfig=(WifiConfiguration)getWifiApConfigurationMethod.invoke(wifiManager); 
    Log.e("CLIENT", "\nSSID:"+netConfig.SSID+"\nPassword:"+netConfig.preSharedKey+"\n"); 
} catch (Exception e) { 
    Log.e(this.getClass().toString(), "", e); 
} 

Answer 4

आप WPA_PSK प्रमाणीकरण का उपयोग कर रहे हैं, आपको यह निर्दिष्ट करना
