Unable to run the apk generated in release mode

dedeepya yarlagadda 50

I have .Net MAUI app, version .net8. The release build is built without errors but when I run it is not opening the app and it is crashing.

Please let us know if there are any additional settings required here.

Thanks

Hi Leon Lu,

Thanks for responding.

Yes, if I run the installed app it is crashing please find below the csproj.
In the device log I am seeing some null pointers due to dependency injection.

I create a demo with your released settings and the installed package. I can install generated APK in my emulator. Can you share a mini demo with us? And share these specific errors in the device log.

Hi Leon Lu,

Thanks for your response.

I have verified the device log and I am able to trace the issue, there is an issue of passing the bindingcontext in OnPageChanged() method due to which it is throwing a null pointer. Now the app is opening after installation.

Thanks

Hello,

You can open this Device log(Tools->Android->Device log), when you open your application, will you get some errors or exceptions in the device log?
