【问题描述】:
我尝试使用以下代码以编程方式更改 android 中的移动 hotsport 广播频道,但它没有更改任何值/频道。
注意:我可以通过编程方式更改 SSID 和密码。
我试图设置频道 11,
还是不行……
提前致谢
我的代码是
public void HotspotChannelWrite() {
WifiManager wifiManager = (WifiManager)getSystemService(WIFI_SERVICE);
if(wifiManager.isWifiEnabled())
{
wifiManager.setWifiEnabled(false);
}
netConfig = new WifiConfiguration();
netConfig.SSID = "TipturInfo";
netConfig.preSharedKey = "Sharath";
netConfig.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.OPEN);
netConfig.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
netConfig.allowedProtocols.set(WifiConfiguration.Protocol.WPA);
netConfig.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
netConfig.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);
netConfig.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
netConfig.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
netConfig.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
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.i("Writing HotspotData", "\nSSID:"+netConfig.SSID+"\nPassword:"+netConfig.preSharedKey+"\n");
// For Channel change
Field wcAdhocFreq = WifiConfiguration.class.getField("frequency");
int freq = 2462; // default to channel 11
wcAdhocFreq.setInt(netConfig, freq);
Log.i("HotspotData Channel", "\n Frequence:"+freq );
Log.i("HotspotData Channel", "\n Frequence:"+wcAdhocFreq );
// For Saving Data
wifiManager.saveConfiguration();
} catch (IllegalFormatException ife) {
ife.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
wifiManager.saveConfiguration();
}
我也尝试了其他方法:
Field wcFreq = WifiConfiguration.class.getField("channel");
wcFreq.setInt(netConfig,11);

@Adnanul,上面的链接用于以编程方式打开/关闭 WiFi 热点,但我的问题是专门更改移动热点广播频道..???谢谢,
-
kgsharathkumar ,你有可用的热点广播频道吗?这应该是第一步吧?
-
是的,我已经完成了,我需要最后一步吗??
