Suppose I get a call at my android phone. What I want is this call to be routed to my bluetooth/wifi connected PC just like it is routed to any other android audio device.
If you have embedded Bluetooth hardware just use accompanying software and set your PC (after pairing) headset/speakers as a Hands-free device. That's it.
If you have BT USB-dongle try to install Bluesoleil software and do the same as above. It's simple but not very stable piece of s..oftware, so it may work or it may not. In this case you can try Broadcom WIDCOMM Bluetooth Driver 12.0.1.940 and again set that so you could use your PC headset as a Hands-free device.
I'm sorry I can't tell you exact steps because I don't have Bluetooth on my PC atm. But believe me it's very easy. It was some time ago but it was like half a minute to set things up.
Hope this will help.

My question is how can I forward a port automatically in a server.
If anyone knows the game "Minecraft" the user have an option to create a server so anyone can join.
Now what I didn't get is how the server automatically forward the port.
Currently i do not have any code to show.
Thanks In advance.
What minecraft does is creates a local port that is listening for connections. I think what you are asking though is how does the other user get through your router to your server. The answer to that is it uses UPnP to tell your router what ports to forward from the wider Internet.
If you want to implement something similar, look for UPnP libraries for Java or whatever language you are writing in.

I have an android application APK that has been burnt in the android OS. So it becomes its native application. So can you please guide me how I remove it after OS burnt on the phone. If I cant remove it without root access. Can I update this native application by any way. It is not uploaded on Google Play. So can I do this that I can upload its newer version on Google Play Store and then update manually from device android market/play store application?
Please guide me if this option is valid or not. If yes then How? And If No then how can I achieve this.
Thanks in Advance...
been burnt in the android OS
No. It's only installed on (by default) read-only partition.
So can you please guide me how I remove it after OS burnt on the phone
You need write access to that partition => root
Can I update this native application by any way
Yes. Just install any new app with the same package id and singed with the same certificate the ROM-installed version is and you got it updated

I want to send the input of a couple of wireless (network) bar code scanners to my java web application. I couldn't find any documentation on how these wireless scanners work or if it is even possible to send the input of multiple bar code scanner devices to a single server. The best option would be a scanners that could connect to a ReST API via wireless network.
Is it possible to send data from multiple bar code scanners to one server?
And how could it work? Or do I need some kind of client software on a PC to read the bar codes and then send them over the network to my server?
Thanks
Claus
A scanner usually works as a keyboard. Wireless probably means just cordless, So yes, you need some application in between.

I was wondering if it was possible to write a Java Android coder output a short 5V pulse out the datawire of the USB port, on the Android device
USB is not designed for such a use, so your choices are either to misapply it, or to use it to ask something external to do what you want.
From the bare USB port, you could only do this by briefly enabling the USB VBus charge pump on a device with that capability, which would be a root-access (or quite possibly, kernel-driver) level task - and that would not of course be on the data line, but instead on the VBus line.
With an external microcontroller and circuitry connected, you could accomplish your end goal using either the ADK interface or USB host mode if supported, by having an app communicate a request to the micro to do it.
Most likely no, the developers would never implement something like that. It's only possible by modificating the Android software, you would find it here http://developer.android.com/reference/android/hardware/usb/package-summary.html otherwise (I searched a bit but didn't find a method like that, you can only send data and stuff but you can't control the voltage and stuff like that).

I'd like to do some development of smart phone apps and my native programming language is java.
The first application I'd like to write will need to be able to (attempt to) connect to a network (LAN or WiFi) automatically in the background (on a schedule).
would an android phone be the best path or are there competitive purer java options?
I would definitely go with Android, extensive SDK, community, and increasing popularity. I think the What is Android answer on the developer web site says it all.
"Android is a software stack for
mobile devices that includes an
operating system, middleware and key
applications. The Android SDK provides
the tools and APIs necessary to begin
developing applications on the Android
platform using the Java programming
language."
I think Android is the best start path today.
The main options would probably be BlackBerry, J2ME for Nokia ect, or Android. I personally would recommend Android. BlackBerry is overall a little more work than Android and the pure J2ME option is incredibly underpowered in comparison to either.
Blackberries use java applications, so that wouldn't be a bad choice.
