In case of transferring the files you can make an explicit call to ACTION_SEND using intents as shown below.

You can send a file to a paired device through obex in a couple of ways:

With the ACTION_SEND intent, that will popup a menu with the application that can handle the file type you want to send, from which the user will need to select bluetooth, and then the device.

Intent i = new Intent(Intent.ACTION_SEND); i.setType("image/jpeg");    
i.putExtra(Intent.EXTRA_STREAM, Uri.parse("/sdcard/file.jpg")); 
startActivity(Intent.createChooser(i, "Send Image"));

I think this will help u . :)

  • File sourceFile = new File("//mnt/sdcard/TviderFB.apk"); Intent intent = new Intent(); intent.setAction(Intent.ACTION_SEND); intent.setType("image/jpeg"); intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(sourceFile)); ctx.startActivity(intent); – vidit Jul 04 '11 at 12:37

Follow these steps:

  1. Read your source file to a byte array (buffer)

  2. Call the write method of your chat service instance passing the bytes to be sent:

    // mChatService is your Bluetooth chat service  
mChatService.write(buffer);

  3. Edit the Handler for MESSAGE_WRITE and MESSAGE_READ cases
