My source code for sending the file to

Answer 1

This code works with firmware from MediaTek. Tested on Android 4.0.4. Sends the file, without asking anything from the user

public boolean SendFileViaBluetoothOPP(String file_path, String destinationMAC){
    BluetoothAdapter btadapter = BluetoothAdapter.getDefaultAdapter();
    if(btadapter == null)
        return false;

    BluetoothDevice btdev = btadapter.getRemoteDevice(destinationMAC);
    if(btdev == null)
        return false;

    Uri uri = Uri.fromFile(new File(file_path));

    Intent shareIntent = new Intent(Intent.ACTION_SEND)
                        .putExtra(Intent.EXTRA_STREAM, uri)
                        .setType("application/zip");

    List resolvedActivities = getPackageManager().queryIntentActivities(shareIntent,  0);

    boolean found = false;
    for(ResolveInfo actInfo: resolvedActivities){
        if(actInfo.activityInfo.packageName.equals("com.mediatek.bluetooth"))
        {                   
            shareIntent.setComponent( new ComponentName(actInfo.activityInfo.packageName, actInfo.activityInfo.name ) );
            shareIntent.putExtra("com.mediatek.bluetooth.sharegateway.extra.DEVICE_ADDRESS", btdev);
            shareIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS);
            found = true;
            break;
        }
    }

    if(found){
        startActivity(shareIntent);
        return true;
    }

    return false;
}

On older phone from MediaTek with Android 2.2.1 this code launches BluetoothDevicePicker to complete the operation.
