Bluetooth File Transfer

Question

I am developing a Bluetooth application based on the Bluetooth Chat Example from the Android Developer Site. I need to do File Transfer via Bluetooth. Can anybody help me out?

Answer 1

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 . :)

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
