I would like to know about the 'service discovery' mechanisms supported by android - particularly, Printer Discovery. Does android provide such a discovery option? example: support for snmp broadcast? I tried out an application "PrinterShare" link:

I have successfully gotten JmDNS working on Android 2.1 testing on a Motorola Droid by using MulticastLock, but recently got an HTC Incredible as second test device, and JmDNS discovery doesn't work at all.I should mention that broadcasting a service still works and everything appears to run normally, but serviceAdded never gets called. Does anyone have thoughts on why this might be?

If I have my app fetching content from my server, what mechanism should I use on my server to ensure that its my app making the request? Is there any way that I can sign the request to using my app's signature to show its come from my app and not from a stolen version or copycat?
View 4 Replies View RelatedPer the current implementation in Sensor Manager, the SensorThread is polling data per below code, final int sensor = sensors_data_poll(values, status, timestamp); it then checks the sensor type if it is registered and processes the data further. For an application which has registered for only one sensor, still to get that particular sensor data, SensorThread has to execute for atleast N-1 loop most of the time. Can anybody provide the insight as to, why SensorThread is waiting to check the sensor type to be returned by the HAL instead of sending sensor information which is currently registered by that application. Wouldn't that increase the performance?
View 2 Replies View RelatedI'm wondering how vector drawing in Android with the Shape class may resemble another vector drawing standard. Since Shape is a Drawable, and Drawables are usually defined as XML, it sounds a lot like the vector drawing commands in SVG. My question is this: Has anybody created an XSLT transformation, or other mechanism, for converting an SVG drawing description into Android Shapes?
View 3 Replies View RelatedWhat I need is to perform some network operations in background inside a service. I want them to run in a service because, as pointed out in the "developing rest client application" talk from google io, I don't want to loose the result if the activity is brought in background. What sounds quite obvious is to use an Intent Service, and get the result as a broadcast. In this way I am sure the service will die and no consume any other resources when its done, but I need to convert the actions I want to perform to intents and back. Well, I was now wondering if it makes sense to bind to the service instead, at least for getting the result. And a more general question: is the bind mechanism suitable for one shot services, or it just make sense for persistent services? What happens if I call the startService method but the service is already active? Will it start another service, or will it call the onStartCommand of the same service? I am asking this because if I use "regular" non sticky service, it could happen that I need it to perform some action and I don't know if it is already active (and I don't want to have a queue of action waiting for onServiceConnected to be called.

I write a sample code to discovery a Bluetooth headset(jabra BT2035). referece http://developer.android.com/guide/topics/wireless/bluetooth.html#DiscoveringDevices
But it can only discovery my notebook computer. If my notebook computer enables Bluetooth and sets Enabling discoverability.
The SDK document snippet:
android.bluetooth.device.action.FOUND"
public static final String ACTION_FOUND
Since: API Level 5
Broadcast Action: Remote device discovered.
Sent when a remote device is found during discovery. I think the remote device means a remote notebook computer except a Bluetooth headset. Could someone please help with this?
Did anyone else see the article on how to print from your handheld to a printer...from anywhere? Uses dropbox. I didn't see a thread on it.

I was trying that and in holding the focus spot on the screen after a second or so the camera snapped the shot. No push of track thingy. Replicated. Did I just miss this info? I was really surprised. For me, this makes the shot really steady and clear.

View 1 Replies View RelatedThere has been a lot of discussion on Engadget about whether the soft keyboard has multi-touch. Engadget insists no, and Rob here insists yes.I think I discovered where the problem lies. Josh at Engadget was saying that you had to release one key before pressing another or they would not both register. Rob said in his review that you COULD press them at the same time and both would register. I think I found out that both are right.I did some experimenting and would love to see whether others come to the same conclusion. It seems that when the keys are far enough apart (more than a couple of keys away), then you can, indeed, press the second before the first is released and they both register.BUT, if the keys are close to each other, it will not do this. You have to release one key before pressing the other.I think this must be to avoid accidentally hitting two keys with one finger.So, whether you think this is a good feature or too much babysitting of our typing abilities, it does seem intentional.

View 7 Replies View RelatedI am looking for a way to print Office Documents from my phone. I have a WiFi printer. Currently using OfficeSuite Pro. But it has no printing provision that I can discover. So far my workarounds are.
1. Transferring the file from SD card to PC. Opening the file and printing from there.
2. Attach the file and email to myself. Open the attachment and print from there.
I would like to be able to send the file directly from the phone to the WiFi printer. I saw some print apps in the market, but none seemed to do Office Documents.
In the last 3 weeks, I've found that Chrome To Mobile has stopped working for my Chrome browsers on mulitple desktops, to multiple devices. "Print" requests on the Cloud Printer Beta page show my requests, stuck in a perpetual state of "Queued" ... until I delete them.
Deleting and adding the devices hasn't worked. Neither has stopping and restarting Chrome sync.
