Re: bluetooth connection - paring required?

2009-11-25T02:07:51Z

Apparently, I was using the wrong pin for my device. (0000 didn't work
but 1234 did.)

But still a feature to consider. Though, I do appreciate the security
concerns this brings up.

Re: How do I backup my application signing key?

Don't feel too bad, that is bizarre behavior for jarsigner on Vista.
The same thing happened to me, so I made some notes to prevent getting
surprised should something like that happen again. I don't know if
Vista is at fault or if it is some attempt by the JDK to follow a
peculiar Windows convention.

What type of view is it? There are only a handful of view classes that
actually save and restore state (TextView and a few others). What type of
object is it returning? (You could print the state bundle in
onSaveInstanceState().)

So, I was able to successfully connect to the Bluetooth device! Like
you said I had to pair the device. The pin that work in my case was
1234. I was trying 0000 but that did not work.

Thank you!

Re: [android-developers] How to use the dpad button to pause and play audio while the device is locked

Sorry this isn't possible -- when the screen is locked the lock screen gets
focus and no input events are delivered to the app.

How to use the dpad button to pause and play audio while the device is locked

2009-11-25T01:41:34Z

I have an application that is playing audio, and I would like to allow
the listener to toggle between pause and play while the screen is
locked, as it is a hassle to have to unlock the screen in order to
pause the audio playback.

Is there any way to monitor for KeyEvent.KEYCODE_DPAD_CENTER while the

Only Droid Support Bluetooth API?

2009-11-25T01:40:49Z

Hi,
As we know, bluetooth-related APIs was not included until version 2.0.
And the current condition is Droid is the only 2.0-supported choice.

I've known there are many kinds of unofficial 2.0 build, but are they
stable enought to program? Does anybody has the experiences of
programming bluetooth on a non-Droid handset? What is it, and what is

Ah, sorry I assumed you were using Android <-> Android.

Sounds like your remote device already has an SDP record set up with the
well-known SPP UUID, so yes using that UUID on the Android client should
lead to a successful connection.

Android requires pairing to connect to a remote device, even if the remote

Yes I am using Windows Vista and the keystore was exactly where you
said.

When I created my keystore file I was in the directory where the
keytool.exe is located under c:\Program Files\Java\...\bin and it
actually created the keystore file under c:\<username>\AppData\Local
\VirtualStore\Program Files\Java\...\bin.

Re: bluetooth uuid

2009-11-25T01:16:53Z

This got me somewhere. That is, Android tried to connect to the
Bluetooth device but was unable to. I know that this is the 16-bit
UUID for the serial port profile (0x1101) promoted to a 128-bit UUID.
This is what I had initially tried but incorrectly converted.

In my case, I am trying to connect to a Bluetooth device which I

You know how google docs can allow you to share a doc to be edited real time
just like a wave or anything else can? I think that idea should be extended
to the code creation process so that coding can be done on the cloud as
well..

This way, depending on a system like mercurial to do a complex set of
