We have found that these problems are caused by Adcolony, we’ll fix this in our next plugin for Corona. As a temporary solution, you might try to disable Adcolony through segments in your Appodeal dashboard.
I am glad that you managed to reproduce the problem.
I wrote several days ago that the data usage was mainly AdColony m4v videos 
I find it incredible that none of the developers of the Corona/Appodeal/AdColony SDKs and plugins can answer my questions, most of which are explicit although I admit that some are implicit.
For clarity I repeat them here:-
Why did I find more than 1.5GB of AdColony m4v videos on my phone?
Why does AdColony need these to be persistent?
Why can’t it just delete them on exit?
If this is to avoid reloading them, why do I find several files with identical content?
Why are they stored as data and not as cache?
The usage dropped from more than 1.5GB to less than 60MB between the 25th September and the 1st October.
I did not deliberately do anything to cleanup.
Does AdColony perform cleanups based on a “time to live”?
Does AdColony perform monthly cleanups, for instance on the 1st of each month?
I understand that Appodeal has acquired Corona Labs, that this is the appropriate forum for questions related to Appodeal and that Appodeal integrates AdColony.
Doesn’t anyone at Appodeal know how AdColony works?
Is there anyone competent from Appodeal on this forum?
Would it help to file an official bug report?
I am not a developer using Corona, just a user of a game that unfortunately uses Appodeal.
Please help the developers of the game to find a solution quickly.
Such enormous data usage will cause most users to uninstall their application causing loss of revenue for you.
Maybe this will motivate you to find a solution
Instead of suggesting that developers disable AdColony, why don’t you (i.e. Appodeal) disable it temporarily on your side ?
This has two advantages:
- developers need perform no action, apart from possibly a rebuild
- you can put pressure on AdColony to correct the problem if it is on their side
Thank you! Finally good news! I have only two quick questions about it:
- Is there a date for updating the plugin?
2. Can our revenue be lost if Adcolony is disabled?
I can not answer your questions.
However, Karina Shakh said they will make an update so our preoccupations should be resolved …
Please would you kindly indicate:
- the type of solution that you are working on
- whether it is a temporary workaround or a permanent fix
- an estimated release date
I am sure that the application developers concerned would be prepared to test a beta version.
I should be only too pleased to assist in testing at a user level.
