[android-developers] Re: Establishing WiFi connection to a chosen hotspot
A final comment: WifiManager.AddNetwork(conf) will fail if the the AP
you're trying to connect is protected by password and the password you
set in `conf` is incorrect
I have been debugging AddNetwork() failure for half a day, MY GOD!!!

[android-developers] Re: Establishing WiFi connection to a chosen hotspot
Ravi,
I think your current code looks pretty good. Please be aware that the
constant NETWORK_STATE_CHANGED_ACTION maps to
android.net.wifi.STATE_CHANGE.
I am running nearly the same code and I receive the
NETWORK_STATE_CHANGED_ACTION event. Please, make sure that the
addNetwork(configuration) is successful. But based on your post it is.
Could you post the catlog of the entents which you are receiving?

[android-developers] Re: Establishing WiFi connection to a chosen hotspot
I am receiving some events and not all I am looking for. Here is the simple
code that I wrote to experiment with my requirement.
All I wanted to accomplish with my code was:
1. get a list of WiFi hot spots. I have a BoadcastReceiver that gets the
WifiManager.SCAN_RESULTS_AVAILABLE_ACTION intent. I can iterate through the
list and find my hotspot.
2. Pick one, I am interested in. Once I find the hotspot I am interested in,
I create a WifiConfiguration using the results from scan, and add that with
wifiManager.addNetwork.
3. connect it. Then I call wifiManager.enableNetwork. HERE is WHRE I HAVE
PROBLEM. I am expecting this will create a connection, and trigger a
NETWORK_STATE_CHANGED_INTENT. But it doesn't.
Here is the code I am playing with:
package com.example.helloandroid;

import android.os.Bundle;

super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button button = (Button)findViewById(R.id.ok);

}

}

onReceive()===");
if(intent.getAction().equals(WifiManager.SCAN_RESULTS_AVAILABLE_ACTION)) {
if(enabled) return;
List hotSpots = wifiManager.getScanResults();
StringBuffer ssids = new StringBuffer();
for(ScanResult hotSpot: hotSpots) {
String hotSpotSsid = hotSpot.SSID;
String hotSpotBssid = hotSpot.BSSID;
System.out.println("SSID: "+hotSpotSsid+" BSSID:

StringBuffer sBuf = new StringBuffer("\"");
sBuf.append(hotSpotSsid+"\"");
hotSpotSsid = sBuf.toString();
ssids.append(hotSpotSsid+"..");
if(hotSpotSsid.indexOf(CHOSEN_HOTSPOT) > 0) {
List networks =
wifiManager.getConfiguredNetworks();
System.out.println("=> Number of configured
networks: "+networks.size());
Toast.makeText(context,"NUmber of confiured
Networks: "+networks.size(),Toast.LENGTH_LONG).show();
WifiConfiguration wifiConfiguration = new
WifiConfiguration();
wifiConfiguration.SSID = hotSpotSsid;
wifiConfiguration.BSSID = hotSpotBssid;
wifiConfiguration.hiddenSSID = false;
wifiConfiguration.priority = 10;
// add this to the configured networks
int inetId =
wifiManager.addNetwork(wifiConfiguration);
if(inetId < 0) {
System.out.println("Unable to add network
configuration for SSID: "+hotSpotSsid);
Toast.makeText(context,"Unable to add SSID:
"+hotSpotSsid,Toast.LENGTH_LONG).show();
return;
}
[android-developers] Re: Establishing WiFi connection to a chosen hotspot
Ravi,
I would first try to check out whether in general your code is able to
receive the intents you are looking for.
You can verify this with configuring the Wifi settings on the phone
first and then by turning on/off your AP. If you are bale to see the
events, then the next step would be to connect with your own code.

[android-developers] Re: Establishing WiFi connection to a chosen hotspot
Roman,
I have all the permissions you mentioned, plus the intent filters also in my
code. I am trying this code on G1 phone. Still the same problem.
What is the right approach to make a wifi connection to a specific hot spot?
Thanks
Ravi

[android-developers] Re: Establishing WiFi connection to a chosen hotspot
Are you using the following permissions?
How do u setup your broadcast receiver?
Write a method:
private void registerForWifiBroadcasts() {
IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction
(WifiManager.NETWORK_STATE_CHANGED_ACTION);
intentFilter.addAction
(WifiManager.SUPPLICANT_CONNECTION_CHANGE_ACTION);
intentFilter.addAction(WifiManager.WIFI_STATE_CHANGED_ACTION);
intentFilter.addAction
(WifiManager.SUPPLICANT_STATE_CHANGED_ACTION);
mContext.registerReceiver(this, intentFilter);
}
or do this in the Manifest file.
With doing this you should be able to get the state change intent.
