迁移到 Jetpack 撰写错误:不允许未绑定的符号 [英] Migrate to Jetpack compose error: Unbound symbols not allowed

问题描述

我想迁移我现有的项目以部分使用 Jetpack compose.
所以我使用 Android studio 4.2-canary9 打开它并添加了一个 compose 活动，以便 Android studio 添加所需的配置.

I wanted to migrate my existing project to partially use Jetpack compose for it.
So I opened it using Android studio 4.2-canary9 and added a compose activity so that Android studio adds needed configurations needed.

当我尝试运行该项目时，它给了我一个错误:

When I tried to run the project it gave me an error:

e: java.lang.AssertionError: Unbound symbols not allowed

使用 Run with --stacktrace 我向我抛出了这个堆栈跟踪:

Using Run with --stacktrace I have this stacktrace thrown at me:

第一条路线提到了 activity_main 这是一个不是使用 compose 制作的活动.它指的是Kotlin android extensions，用于替换findViewById(state 是一个TextView ID)

The first route mentions activity_main which is an activity not made using compose. It refers to Kotlin android extensions which is used to replace findViewById (state is a TextView ID)

Unbound public symbol for public kotlinx.android.synthetic.main.activity_main/state.<get-state>|-5663767092261428579[0]

以下是一些配置:

• 撰写:1.0.0-alpha02 &1.0.0-alpha04
• kotlin:1.4.0 &1.4.10
• android-gradle-plugin:4.2.0-alpha09 &4.2.0-alpha13
• kotlin-stdlib:jdk8 和 jdk7

• compose: 1.0.0-alpha02 & 1.0.0-alpha04
• kotlin: 1.4.0 & 1.4.10
• android-gradle-plugin: 4.2.0-alpha09 & 4.2.0-alpha13
• kotlin-stdlib: either jdk8 and jdk7

提前致谢

推荐答案

我遇到了同样的问题.作为一种解决方法，我用 ViewBinding 替换了所有 Kotlin 合成.在我做完之后，一切都奏效了.

I had the same problem. As a workaround, I replaced all Kotlin synthetic with ViewBinding. After I did it everything worked.
