从协程调用 ion 客户端时出错 "No interface method setCallback"

Question

根据 Kotlin Extensions - async/await 测试，要使用异步 Web 请求，我应该将调用封装在协程中，如下例所示，取自测试：

private fun myGetAsync(url: String) = GlobalScope.async {
    try {
        Ion.with(App.instance.applicationContext)
                .load(url)
                .asString()
                .await()
    }
    catch (e: Exception) {
        Log.e(TAG,"Fail",e)
    }
}

问题是当我尝试调用协程时，像这样：

runBlocking {     // but this expression blocks the main thread
            Log.d(TAG,"RESULT" + myGetAsync("https://somewhere.earth/notExists").await())
        }

我收到以下库错误：

java.lang.NoSuchMethodError: No interface method setCallback(Lcom/koushikdutta/async/future/FutureCallback;)Lcom/koushikdutta/async/future/Future; in class Lcom/koushikdutta/async/future/Future; or its super classes (declaration of 'com.koushikdutta.async.future.Future' appears in /data/app/com.byte_artisan.mchat2.qua-Rd32X2D4BZg92hn423sVxA==/base.apk!classes4.dex)

我应该如何使用它？

Answer 1

我使用的是旧版本的 com.koushikdutta.ion，与 androidasync-kotlin 库扩展不兼容。我通过将离子库设置为这些版本来修复：

implementation 'com.koushikdutta.ion:ion:3.0.8' 
implementation 'com.koushikdutta.async:androidasync-kotlin:3.0.9'
