@lemonisdead ; The same php works fine with another app. So I don't want to do any change at the server. If there is something can be done at the app, I prefer this.
I have another app for customers (TAKSİ'M Internet Taxi). I used same webview codes as in the TAKSİ'M Driver. Crash never happened. I didn't see until now. So I don't know black screen will be seen when I try to open app after crash.
TAKSİ'M Driver is killed or crashed? I think it is a crash because when there is a black screen, I go to the application manager and I can press on "Force stop". If app is killed by android, i could not press on the Force stop. Because it is already stopped by the android. Am I right?
If the above statements are ok, why app is crashed? Can you see the error logs at the release mode?
@klaus said error log says there is a problem at the JobDone routine and I corrected it. Where can I see error logs during release mode?
TAKSİ'M Internet Taxi zip file and apk ara given attached.
