How to secure Intent data while sending it across applications

I am working on the security aspects of my android application.

I would like to know about the ways to secure the Intent data and extras while sending it from one application to another so that no other application other than these two can snoop it.

One of the brute-force approaches would be to use android's encryption-decryption to encode intent data, is there a better way to achieve the same ??

Thanks in advance.
