Google Translate on Android can now be used to translate text inside any Android app.
“Tap to Translate” as they called it, is available for anyone running Android 4.2 and above. It allows users to access Google Translate from any part of their smartphone without switching apps. To enable the option, users can simply copy the text they want translated and tap on the Google Translate icon that pops up.
There is also an option for responding, which allows users to write in their own language, immediately have it translated, then copy and paste to send. Tap to Translate is available offline as well, notes Google.
This is one of finest features we have seen in Android this year.
