Bluecove now supports android.
to use bluecove on android do the following
- Include latest bluecove-<...>.jar and bluecove-gpl-<...>.jar in classpath (for now, use the snapshot not the latest released version). (you may want to modify these libraries by removing all native libraries from them as android native library will be packaged in another way and these native libraries will create uneeded additional size to the android app and won't be removed by dx compiler).
- If you are using eclipse, create a directory libs/armeabi under the project root and put attached libbluecove.so inside it to be packaged with the resulted android package. (if you are using other tools, make sure resulted .apk package includes directory lib/armeabi and libbluecove.so is inside it). (take care, inside project directory named "libs" and inside .apk is named "lib").
- Use standard JSR-82 APIs just normal.

Hi,

Androbex runs fine on my Google IO handset (like the MyTouch), so this
is not the same problem you have on the hero or galaxy.
JNI_OnLoad looks like it is in intelbth.cpp ()
FYI, I'm building my android app under eclipse which is running on
OSX. JNI_OnLoad is also in OSXStack.mm
I don't think that it should matter that I am building it on OSX but
just mentioned it as I saw OSXStack when I went looking for
JNI_OnLoad.
Any suggestions?

We use bluecove on OSX, Windows and Linux to connect to our Lego
robots. I'm using the same code we use to connect with those.
Maybe our code makes different calls that Androbex and that is why
there is a problem. I am not a good programmer but some people in our
project are, and you are so hopeful we can get this to work.
Anyway, our code which runs fine for OSX, Windows and Linux fails for
Android. Is that because of the Android implementation on the handset
is incomplete or because libbluecove.so needs to be changed. Is there
anything we can do on our projects side?
Can you guess from the error I got. Sorry to not know bluetooth very
well. Thank you very much for your work. Our project appreciates
your time!!!!

This thread
http://groups.google.com/group/android-developers/browse_thread/thread/d80b1157cda06a79/7f6a3fee79713011
suggests to
implement this JNI_OnLoad() in following way:
/*-------------------------------------------
* do nothing but return the version of JNI
-------------------------------------------*/
JNIEXPORT jint JNICALL
JNI_OnLoad (JavaVM * vm, void * reserved)
{
return JNI_VERSION_1_6;
}
What file do I do that in though. I'll try to implement it and
rebuild libbluetooth.so
Any suggestions are welcome.

AFAIK, not implementing a JNI_OnLoad causes a warning or just a trace message not an error.
if you want to implement it, I think returning JNI_VERSION_1_5 may be better because AFAIK android is compatible with java 5 not 6.
but anyway, bluecove works on android without a change as you see in Androbex.
If you can not run bluecove on android, you probably have a different problem.
if you suspect a wrong native library is loaded, review what System.getProperty() returns for these properties on your phone ("os.name", "os.arch", and "java.runtime.name").
bluecove uses these properties to select one of native libraries to load.
are you trying to run a server on the android phone? I think it isn't possible because of a bug in the android platform. see this, http://code.google.com/p/android/issues/detail?id=2537
you can implement a workaround easily as described in the issue detail, but your phone need to be rooted!

You are right. Androbex gives the same warning but works great!

No JNI_OnLoad found in /data/data/com.androbex.activity/lib/
libbluecove.so 0x430c7270
I/System.out( 5879): BlueCove version 2.1.1-SNAPSHOT on bluez

How did you do that? In eclipse, I just put those libraries in the
build path.
I never saw I/System.out( 5879): BlueCove version 2.1.1-SNAPSHOT on
bluez in my app.
Am I not including the jars correctly?

OS_ARCH looks a little funny to me but ...

For some reason the code that works under Linux,Windows and OSX fails
to make a connection. I'll try to debug why. I suspect either:
1) my android build isn't setting up the Bluecove jars correctly
or
2) our code to make a connection is not telling the android where to
find the jars
or
3) OS_ARCH is not right
Any thoughts? Thanks alot for your input!!! It is appreciated.

Hi Mina,
I think your work looks fine. I expect Bluecove to work on Android.
Right now my app is throwing some error due to our looging.
E/dalvikvm( 7139): Could not find method
org.apache.log4j.Logger.getLogger, referenced from method
com.intel.bluetooth.DebugLog4jAppender.<init>
I working on this now and will let you know if it resolves everything.
Thanks again for your work and help!

Hi Shawn,
these 3 properties returns as expected on android.
OS_ARCH is a known bug on android. I think it is fixed and the fix will be ready in next android releases.
the problem of Log4j is because your are trying to compile bluecove on android. this isn't supported yet.
compile bluecove separately and take resulted jars (or use ready made jars) and include them in your android application.

Hello,
I had the same problem as Shawn with the Log4j. Now I've downloaded
the log4j.jar (version 1.2.15), I copied this file to my jre/lib/ext
folder and to the system/framework folder on the android phone. I also
put a reference to this library on my Eclipse project. After that, I
don't get the previous error, but when my application executes the
LocalDevice.getLocalDevice() method, it breaks without exception. Here
is the logcat information:

you don't need to deal with log4j.
just compile bluecove normally (using standard java tools not android-sdk) or use a prebuilt snapshot (found here http://snapshot.bluecove.org/distribution/download/2.1.1-SNAPSHOT/), use the resulted library in your application with the attached native library (or build the native library yourself if you'd like) and this should work.

I try to find the problem by adding the bluecove sources to my
project and it seems to be a problem with the library loading
(libbluetooth.so), but I´m not sure of this. I put this library in a
folder libs/armeabi in my project as you indidcate in the first post
and I put both jars (bluecove-2.1.1-SNAPSHOT and bluecove-gpl-2.1.1-
SNAPSHOT) in the folder system/framework of the phone. Is the file
bluecove-bluez.jar also needed?
I am desperate with this issue, I need it for my projects at work.
Thanks for your time.

Adding bluecove sources to your project will result in problems you talked about of log4j. Use precompiled jars.

I never tried this. may be this is the problem because bluecove jars you are using are built for standard VM which isn't case in android (android doesn't execute standard .class files)
Instead, include these jars in the project to let (.class) files inside them be recompiled with android dx tool and merged with your classes inside one classes.dex file of your application. This should work.
Then be sure that the resulted package contains the native library correctly as I described in the first post.

references in my eclipse project (this is the way I can use it in my
code) and I create a libs/armeabi folder in the root of the project to
include the libbluecove.so as you indicate previosuly. That was my
fist attempt and it doesn't work.

Ok, I can view the content of the resultant apk with winrar, and the
folder lib/armeabi contains the libbluecove.so. Is there any method to
check if the classes.dex contains the .jars of the SNAPSHOTS?

if you are on linux (and may be Mac) you can execute this command
dexdump -h <your classes.dex file> | grep 'Class descriptor' > ~/classes_list.txt
this will printout class names to classes_list.txt
on windows, use dexdump and read the result yourself!

That is a native code crash I believe.

That is fine then.
In Eclipse you can "reference" a project but that doesn't mean the
jars from the project are in the build path. I thought maybe you did
this, but you didn't.
You have added the jars to your build path so that is fine.

One more idea: I put the libbluecove.so file in the libs/armeabi

the bluecove-gpl-2.1.1-SNAPSHOT.jar file. Is it correct? Is it a
possible problem?

Hi,
I had some problems like:
1. When i use the setDiscoverable() method to change to discoverable,
i got this
"Bluetooth Device is not ready. [1] Operation not permitted"
exception.
2. When i use this "notifier = (L2CAPConnectionNotifier)Connector.open
(url);", i got an exception:
"Can not open SDP session. [13] Permission denied".
Is this normal for the 1.6?
I'm a beginner of bluetooth programming.
I don't understand the second exception.
why when i create the connection of l2cap, i got a permission denied
for SDP session?
L2cap work on low level than SDP, why i need open a SDP session for my
l2cap connection?
ps: For discovery devices, it function well.
Thanks so much.

Hello,
the first exception is because changing discovery state on bluez requires root permissions that your application doesn't have.
the second exception is because you are trying to open a server connection, opening a server connection includes adding a record using SDP to make your service discoverable to clients. this is a bug in android framework! there are wrong permissions on bluetooth socket and so, opeing server connections isn't supported unless you have root permissions and fix bluetooth socket permissions yourself before trying to open a server connection.

Hi Mina,
Do you know if there's a quick fix for changing the discovery state?
There was a quick fix for the SDP permission problem in the link that
you provided in the other thread ... just change something in init.rc.
I wonder whether something similar is possible that will fix discovery
state permissions, too.
Note that Android 2.0 allows apps to change discovery state, so it
can't be a fundamental problem.
Cheers
Hank

The key to this is to make your application run in root mode! I don't know if it is possible. It may be possible if you run a patched android image that run all apps in root mode. Do some search on xda-developers.com

Sorry but Android 2.0 apps can change discoverable mode and I am sure
they are not running root.
I guess there must be some permission change that enables this. I'll
keep looking.

to make my device permanently discoverable. Better always discoverable
than never, at least I can now continue to develop apps that rely on
being discoverable until I find a more permanent solution. I'll keep
you posted.

But i have no idea on how to utilise it and can't proceed further. If u can, can u pls mail me a working example to my mail pls.. My mail id is : rash...@enexl.com. Thanks in advance..
