我试图评估我的手机连接到WiFi网络的能力。我想找出身份验证到我的WiFi接入点需要多长时间，获取IP地址需要多长时间等。
我通过这个网站和大量测试取得了很多进展。然而，我似乎永远无法让我的广播接收器触发某些连接状态。我真的很想知道何时检测到身份验证的时间。
现在我知道Android文档上说的认证状态应该是一个容易访问的东西。但是在实践中，使用多个设备，该状态从未达到。我甚至尝试使用以下代码进行轮询。

public void start(long delayMillsec) {
handler.postDelayed(new Runnable() {
@Override
public void run() {
long timeout = System.currentTimeMillis() + 5000;
running = true;
while(true)
{
int oldState = state;
showWifiStatus();
int newState = state;
if(newState != oldState)
{
Log.e("STATE", stateString + ": " + System.nanoTime());
}
}
} }
, delayInMillsec);
}
public void showWifiStatus() {
boolean connected = false;
boolean associated = false;
ConnectivityManager connManager = (ConnectivityManager) thisContext.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo mWifi = connManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
DetailedState val = mWifi.getDetailedState();
if (val == NetworkInfo.DetailedState.SCANNING) {
//Log.e("Detailed Wifi Info"," wifi state is SCANNING ");
state = 0;
stateString = "SCANNING";
}
if (val == NetworkInfo.DetailedState.CONNECTING) {
//Log.e("Detailed Wifi Info"," wifi state is CONNECTING ");
associated = true;
state = 1;
stateString = "CONNECTING";
}
if (val == NetworkInfo.DetailedState.AUTHENTICATING) {
//Log.e("Detailed Wifi Info"," 3wifi state is AUTHENTICATING");
associated = true;
state = 2;
stateString = "AUTHENTICATING";
}
if (val == NetworkInfo.DetailedState.OBTAINING_IPADDR) {
//Log.e("Detailed Wifi Info"," wifi state is OBTAINING_IPADDR");
associated = true;
state = 3;
stateString = "OBTAINING_IPADDR";
}
if (val == NetworkInfo.DetailedState.CONNECTED) {
//Log.e("Detailed Wifi Info"," wifi state is CONNECTED ");
connected = true;
associated = true;
state = 4;
stateString = "CONNECTED";
}
if (val == NetworkInfo.DetailedState.DISCONNECTED) {
//Log.e("Detailed Wifi Info"," wifi state is DISCONNECTED ");
state = 5;
stateString = "DISCONNECTED";
}
if (val == NetworkInfo.DetailedState.DISCONNECTING) {
// Log.e("Detailed Wifi Info"," wifi state is DISCONNECTING ");
state = 6;
stateString = "DISCONNECTING";
}
if (val == NetworkInfo.DetailedState.FAILED) {
//Log.e("Detailed Wifi Info"," wifi state is FAILED");
state = 7;
stateString = "FAILED";
}
if (val == NetworkInfo.DetailedState.IDLE) {
//Log.e("Detailed Wifi Info"," wifi state is IDLE");
state = 8;
stateString = "IDLE";
}
if (val == NetworkInfo.DetailedState.SUSPENDED) {
//Log.e("Detailed Wifi Info"," wifi state is SUSPENDED");
state = 9;
stateString = "SUSPENDED";
}
}
我将立即从后台服务调用start函数，然后在已知的wifi AP之间走动，断开连接并重新连接等等...
我还尝试使用连接性接收器来获取任何可能的信息。
我使用了这个意图过滤器：
IntentFilter ConnectedFilter = new IntentFilter(ConnectivityManager.CONNECTIVITY_ACTION);
ConnectedFilter.addAction(WifiManager.WIFI_STATE_CHANGED_ACTION);
ConnectedFilter.addAction(WifiManager.SUPPLICANT_CONNECTION_CHANGE_ACTION);
ConnectedFilter.addAction(WifiManager.NETWORK_STATE_CHANGED_ACTION);
getApplicationContext().registerReceiver(ConnectedToAPReceiver,
ConnectedFilter);
使用这个接收器，可以输出所有接收到的东西。并且从来没有任何迹象表明身份验证状态被触发过。
private BroadcastReceiver ConnectedToAPReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
Bundle extras = intent.getExtras();
if (extras != null) {
Log.e("NEW Action", intent.getAction());
for (String key: extras.keySet()) {
Log.e("CONN_ACTION", "key [" + key + "]: " +
extras.get(key));
}
Log.e("NEW THING", "------------");
}
else {
Log.e("CONNACTION", "no extras");
}
}};
我正在使用以下权限：
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission>
有没有Android专家可以帮我解决这个问题？最好能够提供一些可用的代码，但是即使能够提供一些关于为什么永远无法到达该状态的信息也会非常有帮助。这是一个错误吗？
谢谢！
