What happened?

A strange bug caused by a "missing feature of java" cause this :react-native-video:compileDebugJavaWithJavac error: /exoplayer/ReactExoplayerView.java:522: error: switch expressions are not supported in -source 11 and tell me to: (use -source 14 or higher to enable switch rules)

I use Azul Zulu JDK 17 on a iMac. So it's really strange that is complaining about a source 11 error (assuming is intending Java 11)

java -version

openjdk version "17.0.11" 2024-04-16 LTS OpenJDK Runtime Environment Zulu17.50+19-CA (build 17.0.11+9-LTS) OpenJDK 64-Bit Server VM Zulu17.50+19-CA (build 17.0.11+9-LTS, mixed mode, sharing)

No bug has been reported nor in react-native-video nor in ExoPlayer repo

Reproduction Link

repository link

Reproduction

Step to reproduce this bug are: Use react-native-video Run react-native run-android, with Azul Zulu JDK 17

which react native version do you use ?

[freeboub]

just for information, your comment is right: The syntax you provided, which uses the enhanced switch expression with the -> arrow notation and returning a value, is supported starting from Java 12 under the preview feature, and it became a standard feature in Java 14.

Here’s a summary of the relevant Java versions:

Java 12: Introduced the new switch expression as a preview feature. Java 13: Continued the preview of this feature with some refinements. Java 14: The switch expression became a standard feature. So, starting from Java 14, this syntax is fully supported and no longer requires enabling preview features.

React native is version 0.71.7. And so, it seems to be a error related directly to ExoPlayer. But it affects react-native-video in the matter that i can't compile app for android. Did i have to open a issue to google/ExoPlayer repo? Because is a thing that is abnormal to happen with JDK 17...and now i'm questioning myself if is a error that happen in non-react native apps that use ExoPlayer...

Like i said, no issue about this i've found online, nor on react-native-video nor in Exoplayer repos. And neither in StackOverflow like sites...So i deduce that is a new error of some update in react-native-video or ExoPlayer

This fixed for me:

Updated(In ReactExoplayerView):

            float speed = switch (which) {
                case 0 -> 0.5f;
                case 2 -> 1.5f;
                case 3 -> 2.0f;
                default -> 1.0f;
            };

TO

            switch (which) {
                case 0:
                    speed = 0.5f;
                    break;
                case 2:
                    speed = 1.5f;
                    break;
                case 3:
                    speed = 2.0f;
                    break;
                default:
                    speed = 1.0f;
                    break;
            }

Then did: npx patch-package react-native-video

Is solved. Thank you very much for help @Ajmal0197

I reopen this because you can track the fix for package. I can confirm that the solution is that of the user i thanked. Thanks again to everyone.

I hade same issue, i'm not a fan of patch, the workaround that work for me was explicit define java version on android/build.gradle

I add this peace of code

subprojects {
    afterEvaluate { project ->
        if (project.hasProperty("android")) {
            project.android.compileOptions {
                sourceCompatibility JavaVersion.VERSION_14
                targetCompatibility JavaVersion.VERSION_14
            }
        }
    }
}

        }
    }
}

This is a better solution.
