Cocossharp freezes when the applcation returns from sleep.

I am using Xamarin Android with Cocossharp with Visual Studio 2017(15.9.12) on Windows 10.

This happens on Android. I already implemented PauseScene and ResumeScene in OnPause() and OnResume() of Android's lifecycle event.

When application is running and user presses the Sleep button on device, after waking up the device and returning from sleep state, Cocossharp will freeze and stop responding to user actions. Pressing Home button on device to minimize the app and selecting the app to run it again makes Cocossharp continues to function again.

I am experiencing the exact same issue. Did you figure anything out @shico ?

Hi @kodamasama

I had tried a lot of things to fix this issue, nothing worked.

But since pressing Home button on device to minimize the app(when Cocossharp freezes) and selecting the app to run it again makes Cocossharp functions again,
I ended up sending the app to background by code when user presses Sleep button on device, after waking up the device, user will have to select the app to run it again manually.
This way, the app can continue working.

Ideally, by sending the app to background by code when user presses Sleep button on device, then relaunching it by code when returning from sleep state could make the app appears to user like normally expected behavior. Unfortunately, relaunching the app by code does not work in this case, Cocossharp will return in frozen state. So manually selecting the app to relaunch it is necessary. It is not beautiful but it is better than the app freezing.

The method I used as a workaround is not ideal so I did not post it here.
I hope this can help you.

I am still hoping to get answer from the dev team.

Thanks for the reply. You're right about that not being ideal, but it does give me some ideas to work with. I'll let you know if I come up with anything better.

Any news on this?

Hi @Junior-OliveiraDeveloper
I used the method mentioned in my answer post to circumvent this issue.

Thanks for answering. I'll go your way

Same issue here.

I suggest switching to SkiaSharp. CocosSharp is abandoned

@Junior-OliveiraDeveloper Thank you for your suggestion.
