Any useful instant translate app on Android phone and tablet?

[Strong Iris]

Is there an instant professional translation software that I can use?
I recently chatted with a Brazilian on WhatsApp. Due to language problems, he spoke Portuguese and I spoke English. I could only copy his message into Google Translate, read it clearly, then input my answer, convert it into Portuguese and forward it to him.

Thank you. I also think Google translator is very useful.
I want to fine easier way-- a suitable app or plug-in that can directly understand the other party's language on the WhatsApp page. It would be best if I can type in English and the chat box will automatically convert it to the target language (I know it's a bit difficult, but I want to find it)
