I ran the pixelknot python detection script that was on here in the last few days on my cache of qresearch image files and found there was a few of them.
Uploaded what i found so far to https://anonfile.com/h8k8Adf3b6/pkfiles.zip as i don't have the computing power to tinker with them.
Wish i had a faster computer. Glad someone can make a go of it.
I do android programming and the C0217R code you psoted looks like resource ids compiled by the either android studio or gradle. They must be manually added because usually they are in R.java or sometimes in BuildConfig.java (in the final apk)
I ran the apk version 1.0.1 (last version listed on the playstore) and couldn't find the C0217R class, ran it through two decompilers and neither had it in its output set of files.
