Hello all,
I am developing an app at my current internship and we use Expo Go to test it. However, just a couple seconds after my app loads, I lose the ability to interact with it. I can still interact with the rest of Expo Go (if I press the triangle back button, minimise, then maximise the application), but my particular app doesn’t acknowledge my input.
However, my app has not frozen even after I lose the ability to control it. I can tell because it sends a network request when it is opened and then changes its appearance when it receives a response - both of which are observable even after I can no longer interact with it.
This issue is not present on any of the other Android apps I use (Signal, Fennec, Protonmail), oddly enough.
So has anyone else had a similar issue? Any ideas on what can be done to troubleshoot or fix it? Any insight is greatly appreciated 
Not an Android developer, so prepare that grain of salt
As you probably can’t share the code, I’d suggest you make a parallel application and start ripping features (=code) out until it stays responsive. It sounds like some thread gets stuck in such way that the application self doesn’t mind, but the testing apparatus gets caught on it.
I forgot to mention this is the original post, but the application had been working perfectly for a while on Sailfish, and then, without me changing anything in the app’s source code, it stopped… I must have changed something on the phone, but I’ve retraced my steps as far as I can remember and cannot think of what it was. So I doubt being an Android developer helps much with the troubleshooting…
You are right, I cannot share the code.
Nice idea, but it does not seem to be working: I grabbed the earliest fully-functioning commit (just a button and a text-input field) and tried running it… the exact same issue arose.
I tried grabbing logs via logcat, but there doesn’t seem to be anything helpful there. Then, I tried reinstalling the Expo Go app; alas, no dice.
For now I’ll just package for web and test there, which is mostly fine.
