我正在尝试评估我的手机连接到我的 wifi 网络的能力。我想弄清楚对我的 wifi 接入点进行身份验证需要多长时间，获取 IP 地址需要多长时间等。
由于这个网站和大量的测试，我取得了很大的进步。但是，我永远无法让我的广播接收器触发某些连接状态。我真的很想以某种方式检测身份验证发生的时间。
现在我知道 Android 文档是怎么说的，并且身份验证状态应该很容易访问。然而，在使用多个设备的实践中，永远不会达到该状态。我什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";
}
}
我立即从后台服务调用启动功能，然后我在已知的 wifi AP 之间走来走去，断开 wifi 并重新连接等...
我还尝试了连接接收器来接收我能接收到的任何东西。
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);
使用此接收器，可以绝对输出接收到的所有内容。并且从来没有任何迹象表明曾经触发过身份验证状态。
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");
}
}};
我也在使用以下权限：
<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 专家可以帮助我解决这个问题？理想情况下，我想获得一些我可以使用的工作代码，但即使是一些关于为什么永远不会达到这种状态的好信息也会非常有帮助。这是一个错误吗？
谢谢！
