最小 Android 应用程序中正常方法调用的奇怪静态方法错误

Question

在使用 Android 编译后，在我的 Android 10 设备上运行一些非常简单的代码（8 行方法；只有 2 行相关）时，我得到一个奇怪的运行时异常Studio Canary 7（或 6）使用 Jetpack Compose alpha12。

错误：

java.lang.NoSuchMethodError: No static method copy-0d7_KjU$default(JFFFFILjava/lang/Object;)J in class Landroidx/compose/ui/graphics/Color; or its super classes (declaration of 'androidx.compose.ui.graphics.Color' appears in /data/app/com.example.myapplication-GbQdisqKhWdQawA6_DsPkQ==/base.apk)
    at com.example.myapplication.MainActivity.onCreate(MainActivity.kt:15)
    at android.app.Activity.performCreate(Activity.java:7955)

代码：

package com.example.myapplication

import android.os.Bundle
import androidx.appcompat.app.AppCompatActivity
import androidx.compose.material.MaterialTheme
import androidx.compose.material.Surface
import androidx.compose.material.Text
import androidx.activity.compose.setContent
import androidx.compose.ui.graphics.Color

class MainActivity : AppCompatActivity() {
 override fun onCreate(savedInstanceState: Bundle?) {
  super.onCreate(savedInstanceState)
  val x = Color(0xFFBB86FC)
  val y = x.copy() // ******* line 15 *******
  setContent {
   Surface(color = MaterialTheme.colors.background) {
    Text(text = "hello world")
   }
  }
 }
}

顶级 build.gradle:

buildscript {
    ext {
        compose_version = '1.0.0-alpha12'
    }
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath "com.android.tools.build:gradle:7.0.0-alpha07"
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.4.30-RC"
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir

}

Answer 1

罪魁祸首是行 classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.4.30-RC"，它应该是没有 -RC 的 1.4.30。我有初始 -RC 版本的原因是因为最新的 Android Studio Kotlin 插件版本确实是 -RC（令人沮丧的是 IntelliJ 没有发布正确的版本，即使它看起来是在 gradle 中可用），并且使用 1.4.30 给出了一个警告，它与 IDE 版本不同。忽略该警告并使用发布版本解决了该问题。

唉！
