There is a very old and abandoned app that I used to like a lot. It is very simple (the size was just 99KB). It is simply creating a floating icon above other apps that initiates screenshots.
When I tried to install and use it on my OnePlus 5, I got the message that this application needs to be updated.
The thing is that there is no update available for this app because the developer for his own reasons abandoned the project.
Could this be because of the modified Android version my device is running? Or is it because the app is no longer compatible for the latest Android versions in general? (My old device was under 4.4 KitKat)
Is there a way to resolve this manually perhaps by decompiling , editing and recompiling the apk?
Is there a way to recreate the same apk to be compatible with the latest bunch of Android versions?
Is there perhaps a way to avoid all the hassle and "trick" the app thinking that everything is O.K.?
Since I am a complete and utter n00b, please explain to me.
I wish to thank you all in advance for your time and effort to answer to me.
