DuplicateClass Conflict with com.google.guava.guava-28.1-android.jar and guava-31.1-android.jar

[AshleyTuring]

Describe the issue
Player does not play on Android. Same code works on iOS.

The line of code breaking on Android is:
bool isOpening = videoPlayer.OpenMedia(new MediaPath(videoClipUrls[j], MediaPathType.AbsolutePathOrURL), autoPlay: false);

NOTE:

We had duplicateClass

#630

We solved this by DELETING ONE ONLY of the following jar files:

1. Assets\Plugins\Android\com.google.guava.guava-28.1-android.jar
   or
2. \Assets\AVProVideo\Runtime\Plugins\Android\guava-31.1-android.jar

To Reproduce

1. Install Unity 2020.3.1f1

2. Install Firebase 7.2.0 SDK all packages

3. Install AVPro "AVPro Video v2.5.0 - 5 May 2022"

4. Run this code

   for (int j = 0; j < videoClipUrls.Count; j++)
   {

            _fuckup.text += "Creating media player: " + j;
   
            //Create new Object to hold the Video and the sound then make it a child of this object
            GameObject vidHolder = new GameObject("VP" + j);
   
   
   
   
            MediaPlayer videoPlayer = vidHolder.AddComponent<MediaPlayer>();
            //videoPlayerList.Add(videoPlayer);
   
   
            ////Add VideoPlayer to the GameObject
            //VideoPlayer videoPlayer = vidHolder.AddComponent<VideoPlayer>();
            //    videoPlayerList.Add(videoPlayer);
   
            //Add AudioSource to  the GameObject
            //AudioSource audioSource = vidHolder.AddComponent<AudioSource>();
   
            //Disable Play on Awake for both Video and Audio
            //videoPlayer.playOnAwake = false;
            //audioSource.playOnAwake = false;
   
            videoPlayer.AutoStart = false;
   
            _fuckup.text += "OpenMedia starting: " + videoClipUrls[j];
   
            bool isOpening = videoPlayer.OpenMedia(new MediaPath(videoClipUrls[j], MediaPathType.AbsolutePathOrURL), autoPlay: false);
   
   
            _fuckup.text += "OpenMedia Completed: " + videoClipUrls[j];
   
            //Changing the media hints for content loaded via Path
   
   
            _fuckup.text += "getting hints: ";
   
            MediaHints hints = videoPlayer.FallbackMediaHints;
            hints.stereoPacking = StereoPacking.TopBottom;
   
            _fuckup.text += "settings hints: ";
   
            videoPlayer.FallbackMediaHints = hints;
   
   
            // UNCOMMENT HERE
            ////We want to play from video clip not from url
            //videoPlayer.source = VideoSource.Url;
   
   
   
            ////Set video Clip To Play 
            //videoPlayer.url = videoClipUrls[j];
            ////Set Audio Output to AudioSource
            //videoPlayer.audioOutputMode = VideoAudioOutputMode.Direct;
            //videoPlayer.isLooping = true;
            ////Assign the Audio from Video to AudioSource to be played
            //videoPlayer.EnableAudioTrack(0, true);
            //videoPlayer.SetTargetAudioSource(0, audioSource);
   
   
   
   
            _fuckup.text += "adding Listener: ";
   
            videoPlayer.Events.AddListener(HandleEvent);
   
   
        }
    }
    catch (Exception e)
    {
   
        Settings.LogError(e);
        _fuckup.text += e.ToString();
    }
   

5. Deploy on iPhone works

6. Deploy on Android Samsung S10, Pixel 5, all

This issue has been resolved.

Steps to solve the problem:

1. Ensure "Project Settings/Player/Publishing" Minify disabled
2. Look for alternate .guava.jar files and remove if not in AVPro file

Thanks for reporting this @livetreetech. In our last release (v2.5.0) we were forced to upgrade the version of the guava library due to ExoPlayer requiring it. We did put in a pre-build process step to detect and offer removal of the old guava library file found in releases prior to v2.5.0 (guava-27.1-android). But this is limited to AVPro Video plugin files.

It looks in your case like guava.28.1-android was brought in by another plugin (Firebase I assume). This will be the case for any plugins that also use guava I suspect.
