WIFI简单的连接及常用密码破解

WIFI所需权限及配置

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

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

<!--使wifi在息屏情况下不断wifi,有需要的话-->
<uses-permission android:name="android.permission.WAKE_LOCK" />

开启WIFI

mWifiManager = (WifiManager) getSystemService(WIFI_SERVICE);
mWifiManager.setWifiEnabled(true);//开启wifi

扫描周围WIFI

//Todo 没有mWifiManager.startScan()就可以直接getScanResults,我试过好像23版本以下就不行了,你的测试机型应该也要25以上吧
//23以下有适配问题,比如startScan之后并不能直接getScanResults(),这样得不到数据
List<ScanResult> mScanResultList = mWifiManager.getScanResults();

连接WIFI

核心连接WiFi代码(可以换不同的密码尝试)
String usePassword = "password";
int netId = mWifiManager.addNetwork(createWifiConfig(scanResult.SSID, usePassword, WIFICIPHER_WPA));
boolean enable = mWifiManager.enableNetwork(netId, true);
//ssid为wifi名,password为wifi密码,type为wifi连接使用的加密算法(一般为WPA)
private WifiConfiguration createWifiConfig(String ssid, String password, int type) {
WifiConfiguration config = new WifiConfiguration();
config.allowedAuthAlgorithms.clear();
config.allowedGroupCiphers.clear();
config.allowedKeyManagement.clear();
config.allowedPairwiseCiphers.clear();
config.allowedProtocols.clear();
config.SSID = "\"" + ssid + "\"";

WifiConfiguration tempConfig = isExist(ssid);
if (tempConfig != null) {
mWifiManager.removeNetwork(tempConfig.networkId);
}

if (type == WIFICIPHER_NOPASS) {
config.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
} else if (type == WIFICIPHER_WEP) {
config.hiddenSSID = true;
config.wepKeys[0] = "\"" + password + "\"";
config.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.OPEN);
config.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.SHARED);
config.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
config.wepTxKeyIndex = 0;
} else if (type == WIFICIPHER_WPA) {
config.preSharedKey = "\"" + password + "\"";
config.hiddenSSID = true;
config.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.OPEN);
config.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);
config.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
config.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
config.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
config.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
config.status = WifiConfiguration.Status.ENABLED;
}

return config;
}
