That is not the same problem. You need to enable Java 8 support: https://developer.android.com/studio/write/java8-support#supported_features
问题解决了吗
android {
...
// Configure only for each module that uses Java 8
// language features (either in its source code or
// through dependencies).
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
// For Kotlin projects
kotlinOptions {
jvmTarget = "1.8"
}
}

我设置了，但是无效，依然还会报错
@Blankyn 升级 AGP 看看，可能太旧了
经过测试，as运行没这个问题，但是打包apk就有这个问题。rxandroid 用2.1.1的也可以，唯独升级后有问题
此处要改成: .addCallAdapterFactory(RxJava3CallAdapterFactory.createSynchronous())

没用的，安卓部分机器有问题，我测试过，目前发现两款机器
确认下依赖 是否都是3系列 com.squareup.retrofit2:adapter-rxjava3:2.9.0io.reactivex.rxjava3:rxandroid:3.0.0io.reactivex.rxjava3:rxjava:3.0.0.addCallAdapterFactory(RxJava3CallAdapterFactory.createSynchronous())

I had this problem too, and finally I found the problem.
The scenario where the problem occurs is:
- I have a library project and an app project, and I package the library project as an aar, and then introduce it into the app project. The library project uses the static method (disposed) of the Disposable interface of rxjava3.
- The problem only occurs when aar is introduced and the app project is packaged as an apk to manually install and run to the device. If you directly depend on the library project, or run it directly with AndroidStudio (whether it is aar dependency or project dependency), there is no problem.
I found two ways to solve or circumvent this problem:
- Change the way to import aar。
from:
implementation(name:"libs",ext: "aar")
to:
implementation(files("libs/libs.aar"))
- Add a property to
gradle.properties
android.enableDexingArtifactTransform.desugaring=false
The cause of the problem lies in the process of desugaring.
When you look at the Dex file in the apk, you can find that the Disposable interface of rxjava3 will be divided into two parts, one of which is Disposable, which contains the declarations of two interface methods, and the other is Disposable$-CC , which contains all static methods. Our code calls static methods through Disposable, so the correct situation should be that when the class in our aar is converted to dex, the call to the static method needs to be replaced with Disposable$-CC.xxxx(), but when we aar is imported with (name,ext) , AGP will not do this for us.
More specific reasons require us to study the behavior of AGP or D8
