我试图评估我的手机连接到我的无线网络的能力。我想知道需要多长时间来验证我的wifi接入点，需要多长时间来获取IP地址等。缺少Android网络连接状态。
我已经取得了很多进展，这要归功于这个网站以及很多测试。然而，我永远不能缝合以让我的广播接收器触发某些连接状态。我真的想以某种方式检测身份验证发生的时间。
现在我知道了Android文档所说的内容，并且认证状态应该很容易访问。然而，在多个设备的实践中，该状态从未达到。我甚至试着用下面的代码进行轮询。
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";
}
}
当我立即拨打了启动功能，从后台服务，然后我走了知WiFi AP间的之间围绕和断开无线网络连接并重新连接等等
我也试过连接接收器拿起我所能做的。
我用这个意图过滤器：
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);
有了这个接收器，输出正被接收绝对一切。并且从来没有任何迹象表明认证状态曾经被触发过。
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");
}
}};
我使用以下权限过于：
<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>
是否有任何Android的专家那里谁可以帮我在这一个？理想情况下，我想获得一些我可以使用的工作代码，但即使是一些关于此状态从未达到的好信息也会非常有用。这是一个错误？
谢谢！
我错过了这一点：mIntentFilter.addAction（WifiManager.SUPPLICANT_STATE_CHANGED_ACTION）; 谢谢！ – Dave
