I want to make notification when wifi signal strength is weak.
If there isn't a listener for wifi , can I create a custom listener for wifi?
The easiest thing to do would be register a listener for the RSSI_CHANGED_ACTION as can be found in the WifiManager.

Below you will find an excerpt from the utodesk documentation for the v7 viewer found here.
There are two event listeners im trying to reference. There is, however, no existing event strings for these. Autodesk.Edit2D.SELECTION_CHANGED and Autodesk.Edit2D.SELECTION_HOVER_CHANGED won't work in my console after the extension is loaded (they just return undefined. Is there a way to find the list of event strings for this extension?
Synchronizing selection
You can also synchronize selection with Edit2D for certain items in your UI using >edit2d.context.selection.
One way to do this is to register a handler. The handler ensures the application is notified if >selection changes.
In the following example, we’ve set the handler to listen for mouse clicks.
// Register your handler
ctx.selection.addEventListener(Autodesk.Edit2D.SELECTION_CHANGED, onSelectionChanged);
Similarly, you can set the handler to synchronize mouse hovering:
// Update UI state on hover changes
ctx.selection.addEventListener(Autodesk.Edit2D.SELECTION_HOVER_CHANGED, onHoverChanged);
You can find the event string for the two event under 'Autodesk.Edit2D.Selection.Events' like below code.
// Register your handler
ctx.selection.addEventListener(Autodesk.Edit2D.Selection.Events.SELECTION_CHANGED, onSelectionChanged);
// Update UI state on hover changes
ctx.selection.addEventListener(Autodesk.Edit2D.Selection.Events.SELECTION_HOVER_CHANGED, onHoverChanged);
I have use featherjs in server-side, unfortunately , feathers-client in android not supported anymore.So , i think i need to use only socket.io-client to listen to feathers serivce event, but i don't know how to do it
The direct Socket.io API is documented here and the listening to custom events section shows how to listen to a custom event:
socket.on('messages myevent', function(data) {
console.log('Got myevent event', data);
});
Make sure event channels are set up accordingly.
I'm using the web speech API but once a bit of time passes by (a minute or 2) without any vocal input, it stops listening entirely. I know this because I have it log its parsed text to the console, however, it stops doing this when I do not talk for a minute or two.
Is there any way to fix this?
You can listen to the end event and then restart the recognition on the SpeechRecognition object.
You should use a boolean flag for deciding (in the onend event handler), when to restart the recognition (and when not to restart).
You could use the other recognition-related events for this.
E.g. Chrome triggers the following event handlers when recognition is started:
1. onstart
2. onaudiostart
(only if sound / speech is detected)
3. onsoundstart
4. onspeechstart
If no sound speech is detected, only the first 2 will be triggered, and then, after some timeout, the corresponding end events (in reverse order).
A simple solution for this could probably be to listen for the end event and restart the recognition
recognition.addEventListener('end', recognition.start);
recognition.addEventListener('end', () => recognition.start()) works but Chrome browser seems to obstrruct the continuity by generating a pop-up to Allow or Block the microphone every 5-7 seconds.
I create app for android. I need catch event exit the application. On the PC all work - I catch exit event. When I testing on the devise event didn't work.
What kind of event it is? Please help.
Listening to the NativeApplication's EXITING event should work...
NativeApplication.nativeApplication.addEventListener(Event.EXITING, applicationExitHandler);
private function applicationExitHandler(event:Event):void
{
trace("exit")
}
However, the app on Android may be going into the background, and not actually exiting. To listen for this, use the DEACTIVATE event...
NativeApplication.nativeApplication.addEventListener(Event.DEACTIVATE, applicationDeactivateHandler);
private function applicationDeactivateHandler(event:Event):void
{
trace("background")
}
Likewise, listen for the ACTIVATE event when the app comes to the foreground.
Is there any event to detect internet conectivity in flex or actionscript3.I tried URLMonitor and networkInfo classes,is there any other event to detect because in URLMonitor class I need to add an url to it which is not possible in my case and in networkInfo class,it does not get called every time.
My requirement is when the application and suddenly if the connection goes off I need to raise an error.Any ideas??
Thanks in advance!!!
What I do in my applications is (I'm using amfPhp) have a onFault handler. So when x amount of time nothing comes from the server show the user a popup message. Yes, it's not as fast as you would want it , but it works.
