Build error "The type 'BaseVideoView' already contains a definition for 'PlayerStateChanged'" when integrating android library in .net maui application

Suvarna KR 0

I have an native android library for video player and added this library(.aar) to android binding library in .net maui 8.0 to integrate the library with .net maui. I have followed the steps in the link "https://www.reddit.com/r/dotnetMAUI/comments/1blorzr/integrating_native_third_party_sdk_in_net_maui/" .But getting the build errors which are shown in screenshot. To fix these errors i added a metadata file by adding the class modes. After adding the metadata.xml all the build errors are resolved, but the .net classes generated by the metadata file added doesnot have the methods available in android library. Please provide the solutions to fix these build errors.

Thanks for the reply.

I am getting multiple build errors as i have attached in screenshot.

The type 'BaseVideoView' already contains a definition for 'PlayStateChanged'

'IjkPlayerFactory' does not implement inherited abstract member 'PlayerFactory.CreatePlayer(Context?)'

'AndroidMediaPlayerFactory' does not implement inherited abstract member 'PlayerFactory.CreatePlayer(Context?)'

The type or namespace name 'AudioFocusHelper' does not exist in the namespace 'Xyz.Doikki.Videoplayer.Player' (are you missing an assembly reference?)

'BaseVideoView' does not implement interface member 'IMediaPlayerControl.SetRotation(float)'

Below are the steps to reproduce this.

I have an native android library for video player.

I have created a .aar file from this library.

Created a new android binding library and added the above .aar file and building the project. But this project is giving build error as mentioned above

Thanks for your feedback.For these issues, does this document on common problems and solutions provided by Xamarin help them?

Troubleshooting Bindings

Since the binding library is quite special, for further investigation, could you please provide an AAR file without private information to reproduce this issue?

Thanks for your feedback.

I reproduced the issue using the project you provided and verified that the workaround in the official documentation does not resolve the issue. For the Binding Library, there are still a number of potential issues that are not easy to troubleshoot.

Therefore, it is recommended that you post this issue to the official repository so that the development team is aware of it.
