HTC Android mobile phones cannot modify Hotspot SSID names and passwords

Some htc phones seems to use a class of type HotspotProfile to keep its configuration. So, before callingsetWifiApEnabled, you need set the ssid in htc's way: [java]

Boolean isHtc = false; try {isHtc = WifiConfiguration. class. getDeclaredField ("mWifiApProfile ")! = Null;} catch (java. lang. noSuchFieldException e) {isHtc = false;} WifiConfiguration apConfig = new WifiConfiguration (); apConfig. SSID = "H3c_xx"; apConfig. preSharedKey = "h3a7ch3c"; apConfig. allowedKeyManagement. set (WifiConfiguration. keyMgmt. WPA_PSK); if (isHtc) {setHTCSSID (apConfig) ;}// sets the hotspot Method through reflection call; method = wifiManager. getClass (). getMethod ("setWifiApEnabled", WifiConfiguration. class, Boolean. TYPE); // return the hotspot open state boolean flag = (Boolean) method. invoke (wifiManager, apConfig, true );

 

Set the SSID and password [java]

    public void setHTCSSID(WifiConfiguration config) {          try {              Field mWifiApProfileField = WifiConfiguration.class                      .getDeclaredField("mWifiApProfile");              mWifiApProfileField.setAccessible(true);              Object hotSpotProfile = mWifiApProfileField.get(config);              mWifiApProfileField.setAccessible(false);                  if (hotSpotProfile != null) {                  Field ssidField = hotSpotProfile.getClass().getDeclaredField(                          "SSID");                  ssidField.setAccessible(true);                  ssidField.set(hotSpotProfile, config.SSID);                  ssidField.setAccessible(false);                      Field localField3 = hotSpotProfile.getClass().getDeclaredField(                          "key");                  localField3.setAccessible(true);                  localField3.set(hotSpotProfile, config.preSharedKey);                  localField3.setAccessible(false);                      Field localField6 = hotSpotProfile.getClass().getDeclaredField(                          "dhcpEnable");                  localField6.setAccessible(true);                  localField6.setInt(hotSpotProfile, 1);                  localField6.setAccessible(false);              }          } catch (Exception e) {              e.printStackTrace();          }      }  

 

You can view the modifiable values by traversing the attributes: [java]

public void dumpHTCWifiFunction2() {      Log.e(TAG, "dumpHTCWifiFunction2++");      // Method[] classMethods = null;      Field localField1;      Field[] fieldlist;      WifiConfiguration apConfig = new WifiConfiguration();      try {          localField1 = WifiConfiguration.class                  .getDeclaredField("mWifiApProfile");          localField1.setAccessible(true);          Object localObject2 = localField1.get(apConfig);          localField1.setAccessible(false);          if (localObject2 != null) {              fieldlist = localObject2.getClass().getDeclaredFields();              for (int i = 0; i < fieldlist.length; i++) {                  Log.e(TAG, "found api: " + fieldlist[i].getName()                          + " type:" + fieldlist[i].toString());              }          }        } catch (NoSuchFieldException e) {          e.printStackTrace();      } catch (IllegalArgumentException e) {          e.printStackTrace();      } catch (IllegalAccessException e) {          e.printStackTrace();      }        Log.e(TAG, "dumpHTCWifiFunction2--");  }
