One of my logs is returning the following message:
12-07 10:42:45.201 6622-17013/? D/DownloadManager: 23 Starting {Apk-apks_1.1.017-812_releaseVersion.apk} by {10112:com.google.android.gm}
I believe com.google.android.gm
represents my gmail account but not sure. Need more insights.
Yes that is indeed the Gmail android app. Any links clicked via the Gmail app have this as the traffic source.
You can see the ID here: https://play.google.com/store/apps/details?id=com.google.android.gm
