android-wifi

i want to make a modification to my project and right now the project status is..... it is searches the available WiFi networks and shows the list with info of the network this works properly.Now i want to search and see the details of the devices connected to the network. Is there any way to find these devices ? Your comment will be useful for me, Thanks. Would you like to discover a specific device ? Or you need the list of all connected devices? The second I don't think is possible. EDIT Discovering specific devices: Using UDP Broadcast . Some reference can be found here ! There are some

i tried to explain the problem in this gif basically, this test app receives an "RSSI_CHANGED" intent and displays the scan results on the screen. scan results are always empty unless GPS is enabled. I guess my question is why? To access the hardware identifiers of nearby external devices via Bluetooth and Wi-Fi scans, your app must now have the ACCESS_FINE_LOCATION or ACCESS_COARSE_LOCATION permissions I have "ACCESS_COARSE_LOCATION" granted You must declare ACCESS_COARSE_LOCATION or ACCESS_FINE_LOCATION . A location permission is required because Bluetooth scans can be used to gather

this has many similar questions (google for: "no internet access detected. won't automatically reconnect." or: android force wifi connection programmatically). i thought i had a answer here , but it stopped working after installing 6.0.1 updates (i have may 1 security patches). seems like this is a behaviour change . i have some 2013 nexus 7's with 6.0.1 that run a kiosk type app and want to connect programmatically to a specific wireless network that has no internet connection. each tablet has a unique static ip address of the form: 192.168.0.xx. i use the normal java socket constructors and

As of Android 4.1, your device can detect if it's connected to a mobile hotspot (given that the mobile hotspot is also running Android 4.1 or higher). Also, you have the option to flag networks as mobile hotspots (under Settings / Data Usage / Overflow menu / Mobile Hotspots). But how do I detect this as a -user- I meant developer? It's not stored in the WifiConfiguration, so where is it? Some context: I want to build a simple tool for Android that checks if you are connected to a network that you or Android has flagged as a mobile hotspot. If so, it will check if no other (non-hotspot)

It seems to me that there is a lot of confusing resources regarding the proxy topic on Android. First of all, it seems that all the methods of the Proxy class are declared deprecated and it's suggested to: "Use standard java vm proxy values to find the host, port and exclusion list. This call ignores the exclusion list." The official java vm proxy values can be accessed in the following way: System.getProperty("http.proxyHost") System.getProperty("http.proxyPort") System.getProperty("http.nonProxyHosts") This could seem confirmed by the documentation of the ProxySelector class . But trying on

I've tried to register a Wifi BroadcastReceiver to get the wifi state when it changes. But so far I have no luck receiving the broadcast. <application android:icon="@drawable/ic_launcher" android:label="@string/app_name" > <receiver android:name=".WifiReceiver" > <intent-filter> <action android:name="android.net.wifi.WifiManager.WIFI_STATE_CHANGED_ACTION" /> <action android:name="android.intent.action.PHONE_STATE" /> </intent-filter> </receiver> //activity declaration here... </application> Do you guys know how to register the BraodcastReceiver in manifest? I don't want to register it in
