Avast is reporting application as Torjan

I have updated my applciation on Playstore. Now whenever user installs this app, system scans it and report it as trojan. I checked it, only definition from Avast are reporting it as trojan. I tried to check what code snippet is triggering this, but I wasn’t able to identify any. Please help me resolving this issue, or atleast there should be some report which identifies which portion of the code is actually making problem.

here is the link of my application:

https://play.google.com/store/apps/details?id=com.secapp.tor.conion&hl=en_US

please help me.

My APK has size of 39MB, I am trying to upload my file here, after sometimes it fails. Anyway I am trying again.

Limit is 50 MB, so it should work.
