Not knowingly. Sounds like there is a phony app as a phishing style infection vector:
"The malware masquerades as a legitimate or popular app that uses the names App, MMS, whatsapp, and even Pokemon GO. When the app is launched, it base64-decodes a string from the resource file and writes it down, which is actually the malicious Android Application Package (APK)."
The user has a legitimate expectation that the app sandbox containment provided by the OS works and nothing bad should happen if s/he tries out the aforementioned apps.
That link says right at the top, "The difference between this type of malware and a legitimate application with similar functionality is that the installation is done without the user’s knowledge."
I agree with @debatem1, this is not what "backdoor" commonly means, phishing does not count as "without the user's knowledge". Phishing is a trick to get in the front door.

This type of malware are commonly called backdoors, see eg. http://www.virusradar.com/en/glossary/backdoor
