esmasui / backport-android-bluetooth Goto Github PK

What steps will reproduce the problem?
1. The phone is paired to, but not connected to, my laptop and a serial 
bluetooth dongle
2. Bluetooth is ON
3. I call Set<BluetoothDevice> pairedDevices = 
mBluetoothAdapter.getBondedDevices(); in my application


What is the expected output? What do you see instead?

I expected it to find two devices. Appearently one of them (the laptop) makes 
it crash with an IllegalArgumentException in BluetoothDevice.<init>

What version of the product are you using? On what operating system?
HTC Magic with Android 1.5

Hi,

I got an error when I call getName() of BluetoothDevice class.
I'm using Hero. The following are the logs.

What steps will reproduce the problem?
1. Try to open a socket

What is the expected output? What do you see instead?
Expected: Open socket, or exception.
Actual: Process just crashes, and app restarts. No exceptions are thrown, but 
there is a BlueZ log:

Hi,

I'm just wondering if you have a sample application, you could make 
available to download, as i cant it working. I'm pretty sure its my 
implementation, so a sample application would be great.

Cheers

James

Could one please provide instructions on how to build the jar from source?

I have tried javac'ing src path, gen, and resource, but lost on the actual 
correct procedure. Am I supposed to compile against 1.6 android.jar or possibly 
2.0?

Great work! Thanks a bunch for the effort thus far. I have been able to 
successfully use the jar as built but would like to make modifications and 
rebuild.

Thanks again.

I was wondering if the developer of this backport API could contact me as I
have a few questions regarding this API.

I was wondering if it worked on the HTC Dream (G1) as well as how stable it is.

What steps will reproduce the problem?
1. BluetoothAdapter.getDefaultAdapter() causes unCaught Exception on Samsung 
Behold II
2.
3.

What is the expected output? What do you see instead?

Expect instance of BluetoothAdapter to be returned

What version of the product are you using? On what operating system?
jar version 2.2.2

After building and starting backport.android.bluetooth application, I see that 
exception occurred and program closed.

It seems that exception happens somewhere in 
ServiceLocator::getServiceStubInternal. Is it possible to avoid this issue on 
my device?

Device: LG GT540
Operating system: Android 1.6
Build: GT540-V10g-JUN-25-2010

Unfortunately I was not able to run debugging on device (i'm beginner in 
android). I hope that this information is enough to determine root cause.

Thanks

What steps will reproduce the problem?
1. Trying to connect socket using UUID for UUIDHelper.RFCOMM_PROTOCOL_UUID
and UUIDHelper.SERIAL_PORT_PROTOCOL_UUID and giving this exception
2- On debugging found that below line is returning value as false;

  mService.getRemoteServiceChannel(mDevice.getAddress(), uuid16, this);
in class BluetoothSocket$SdpHelper


What is the expected output? What do you see instead?
It should get connected properly to the already paired device but not
connecting. Stack trace is like

I am able to get the address and name of the devices available in range but

Can anyone help me to get solution or workaround of this?

I was trying to turn bluetooth off,so I wrote this code:
BluetoothAdapter btAdapter = BluetoothAdapter.getDefaultAdapter();
btAdapter.disable();

But it doesn't work.Instead,it throws an error.

android.bluetooth.IBluetoothDevice$Stub$Proxy.disable(IBluetoothDevice.java:522)

What steps will reproduce the problem?
1. Download and build backport-android-bluetooth201
2. Install on 1.6 device (HTC mytouch)
3. "Connect a device", then send a chat string
4. Android device throws an exception (full exception log is attached)

02-03 19:04:56.725: ERROR/BluetoothChatService(1088): Exception during write

02-03 19:04:56.725: ERROR/BluetoothChatService(1088): java.io.IOException:
Transport endpoint is not connected




What is the expected output? What do you see instead?
No exceptions, and some data over the bluetooth path.


What version of the product are you using? On what operating system?
Android FW 1.6, backport-android-bluetooth201


Please provide any additional information below.

Discovery and pairing works fine.  It just that I can't send a chat over
bluetooth.  I should also mention that I am connecting my android device to
a notebook.  Is that possible the problem?  Have you seen this code to work
with Android <-> notebook?

What steps will reproduce the problem?
1. Connect to a remove device
2. Disconnect remote device from power

What is the expected output? What do you see instead?

The currently open socket should indicate a connect loss, but nothing
happens at all. When I disconnect the remote device by a disconnect command
rather than just remove them from power then it works and the socket throws
an expected exception. But why not when the remote device disappears by a
power loss?


What version of the product are you using? On what operating system?
HTC Magic with Android 1.6

Please provide any additional information below.

Hi,

I run the backport successfully on a HTC Magic (Android 1.6), now I tried
to get the same app running on a Motorola Milestone (Android 2.0.1) which
does not work, see the log below. What do I miss? Any help is highly
appreciated.

What steps will reproduce the problem?
1. Get a BluetoothSocket via 
BluetoothDevice.createRfcommSocketToServiceRecord(UUID) from a device which is 
known but has Bluetooth disabled,
2. Call BluetoothSocket.connect()
3.

What is the expected output? What do you see instead?
I expect to get the promised IOException because the connection was not build 
up properly. Instead the connection process seems to work fine.

BluetoothSocket.getInputStream()/.getOutputStream() also return objects but 
using read() and write() lead to IOExceptions.

What version of the product are you using? On what operating system?
Version 2.2.2

Please provide any additional information below.
See BluetoothSocket.connectNative() in the sources. When catching the 
IOException only a Log.e() is done but no IOException is thrown.

Hi, I am using the latest svn version of backport-android-bluetooth and
just deployed it to my Hero (with rom HTC Generic 2.73.405.66 not rooted).

When I launch the bluetooth application it runs, but when I try to detect
devices I get null for every names.

I attached the logcat containing what happened starting from the run of the
app and I made my phone discoverable and after I tried to discover phones.

I didn't try yet to pair it with another phone and try exchanging message,
but I will in the next hour :)
