android-compose/sample问题汇总

最近项目不忙 就想学下compose. 官方github代码地址
https://github.com/android/compose-samples

嗯,第一步clone下来,是个文件夹,随便打开个项目先看下项目结构

编译一下,这里出现了第一个错误

This version of the Android Support plugin for IntelliJ IDEA (or Android Studio) cannot open this project, please retry with version 2020.3.1 or newer.

报as版本不是最新的
修改这里

  //  const val androidGradlePlugin = "com.android.tools.build:gradle:7.0.0-alpha14"
    const val androidGradlePlugin ="com.android.tools.build:gradle:4.2.0-rc01"

问题搞定 继续编译
出现了第二个问题

e: This version (1.0.0-alpha13) of the Compose Compiler requires Kotlin version 1.4.30 but you appear to be using Kotlin version 1.4.31 which is not known to be compatible.  Please fix your configuration (or `suppressKotlinVersionCompatibilityCheck` but don't say I didn't warn you!).

我以为是kotlin版本问题修改之后 发现根本解决不了，kotlin版本位置如下

    object Kotlin {
        private const val version = "1.4.30"
        const val stdlib = "org.jetbrains.kotlin:kotlin-stdlib-jdk8:$version"
        const val gradlePlugin = "org.jetbrains.kotlin:kotlin-gradle-plugin:$version"
        const val extensions = "org.jetbrains.kotlin:kotlin-android-extensions:$version"
    }

后来看到后面有一句这个suppressKotlinVersionCompatibilityCheck，根据这个问题查到这个文章

https://stackoverflow.com/questions/66369899/why-kotlin-collections-is-not-implicitly-imported-after-upgrading-to-jetpack-com

在app下的build.gradle加入以下代码

            //freeCompilerArgs += ["-P", "plugin:androidx.compose.compiler.plugins.kotlin:suppressKotlinVersionCompatibilityCheck=true"]

又解决一个问题，但是还没完，运行完装好了打开app就崩溃报错

java.lang.NoSuchFieldError: No static field Companion of type Landroidx/compose/foundation/layout/BoxScope$Companion; in class Landroidx/compose/foundation/layout/BoxScope; or its superclasses (declaration of 'androidx.compose.foundation.layout.BoxScope' appears in /data/app/com.example.jetcaster-r7o7MJoqD6RW9icxLk5_1Q==/base.apk)

明天再改吧。。。。
这个问题发现是改动了compose的版本问题,保持不动就好了

            private const val version = "1.0.0-beta04"
