I use in 1 app the libraries baQRcode and NewQRcodereaderview. At compiling I get the following error:

It seems the both libraries together in one app is confilcting. How can I solve this?

 

[zed]

Try this

#MultiDex: True

 

[andredamen]

Try this

#MultiDex: True

Unfortunately this doesn't work. Keep getting the same error message.

Yes I thinks so too. But is there perhaps another lib that reads QR codes and has not zxing in it?
