I recently discovered a new file on my phone, named
.appodeal, at the base of the
Internal shared storage folder.
It appears to be a text file with just 4 characters:
How can I tell what app left it there, and what nefarious/tracking purpose it has?
The phone's currently running Android version 7.1.2.
It seems to be from an ad revenue targetted app by the same name appodeal on the play store and Google search reveals multiple references
Try to track it in your phone using Anti adware or use ad blockers from Izzy's list
This is generated by the Appodeal advertisement SDK integrated in some of your installed apps, likely to act as some sort of flag.
As for telling which app generated it, aside from going the hard way (installing and starting the apps one-by-one), you should also be able to use tools like MyAndroidTools to check the services and broadcast receivers an app possesses. Apps with ad SDKs will likely have services and receivers dedicated to maintaining the SDK.
Thanks to previous posters. In my case it seems to be the RainToday app as the file is regenerated each time I run the app. Fair enough as the app is free if you put up with ads.
