升级到 Jetpack Compose Alpha 12 会导致 setContent 错误 [英] Upgrading to Jetpack Compose Alpha 12 causes errors on setContent

问题描述

我升级到 Jetpack Compose 1.0.0-alpha12 并开始遇到问题.

I upgraded to Jetpack Compose 1.0.0-alpha12 and started to run into issues.

首先，我使用的 setContent 方法显示为已弃用.

Firstly, the setContent method I was using showed as deprecated.

来自 Alpha 12 发行说明，我注意到它说:

From the Alpha 12 release notes, I noticed that it said:

ComponentActivity.setContent 已移至 androidx.activity:activity-compose 模块中的 androidx.activity.compose.setContent.(Icf416)

ComponentActivity.setContent has moved to androidx.activity.compose.setContent in the androidx.activity:activity-compose module. (Icf416)

所以我删除了我的 import androidx.compose.ui.platform.setContent 并将其切换到 import androidx.activity.compose.setContent，这删除了弃用.

So I removed my import androidx.compose.ui.platform.setContent and switched it to import androidx.activity.compose.setContent, which removed the deprecation.

但是，我收到了一个错误消息:

However, I then got an error that says:

w: Flag is not supported by this version of the compiler: -Xallow-jvm-ir-dependencies
w: ATTENTION!
This build uses unsafe internal compiler arguments:
-XXLanguage:+NonParenthesizedAnnotationsOnFunctionalTypes
This mode is not recommended for production use,
as no stability/compatibility guarantees are given on
compiler or generated code. Use it at your own risk!
e: Classes compiled by an unstable version of the Kotlin compiler were found in dependencies.
Remove them from the classpath or use '-Xallow-unstable-dependencies' to suppress errors
e: /[my path]/MainActivity.kt: (39, 9): Class 'androidx.activity.compose.ComponentActivityKt' is
compiled by an unstable version of the Kotlin compiler and cannot be loaded by this compiler

再一次，我可以通过更改我的 build.gradle 文件来解决这个问题:

And again, I was able to work around that by changing my build.gradle file to have:

kotlinOptions {
    jvmTarget = '1.8'
    useIR = true
    // I added this line
    freeCompilerArgs += "-Xallow-unstable-dependencies"
}

虽然让我编译我的应用程序，但我现在在运行时遇到以下异常:

While that let me compile my app, I now get the following exception at runtime:

java.lang.NoSuchMethodError: No static method setContent(
Landroidx/activity/ComponentActivity;Landroidx/compose/runtime/Com
positionContext;Lkotlin/jvm/functions/Function2;)V in class 
Landroidx/activity/compose/ComponentActivityKt; or its super classes
(declaration of 'androidx.activity.compose.ComponentActivityKt' appears in [my apk]

如何解决此问题并将我的应用升级到 Jetpack Compose 1.0.0-alpha12?

How can I fix this and upgrade my app to Jetpack Compose 1.0.0-alpha12?

推荐答案

根据这个问题，这个问题与新的 androidx.activity:activity-compose:1.3.0-alpha01 工件有关.

As per this issue, this issue is related to the new androidx.activity:activity-compose:1.3.0-alpha01 artifact.

来自那个问题:

活动 1.3.0-alpha02 已发布并修复了此问题.

Activity 1.3.0-alpha02 has been released and fixes this issue.

使用 Compose alpha12 的应用程序，特别是像 androidx.compose.ui:ui-test-junit4:1.0.0-alpha12 这样的内部使用 setContent 的工件应该添加 activity-compose:1.3.0-alpha02 对其 dependencies 块的依赖，以确保不使用 1.3.0-alpha01 工件

Apps using Compose alpha12 and specifically artifacts like androidx.compose.ui:ui-test-junit4:1.0.0-alpha12 that internally use setContent should add the activity-compose:1.3.0-alpha02 dependency to their dependencies block to ensure that the 1.3.0-alpha01 artifact is not used

因此，要修复您的应用，您应该:

So to fix your app, you should:

1. 从 build.gradle 文件中删除 freeCompilerArgs += "-Xallow-unstable-dependencies" 行(因为不再需要它)

1. Remove the freeCompilerArgs += "-Xallow-unstable-dependencies" line from the build.gradle file (as it is no longer needed)

添加对 Activity Compose 1.3.0-alpha02 的特定依赖:

Add a specific dependency on Activity Compose 1.3.0-alpha02:

implementation 'androidx.activity:activity-compose:1.3.0-alpha02'

通过添加该依赖项，setContent 的任何直接使用以及 androidx.compose.ui:ui-tooling:1.0.0-alpha12 或 的内部使用code>androidx.compose.ui:ui-test-junit4:1.0.0-alpha12 将使用固定的 Activity Compose 1.3.0-alpha02 版本.

By adding that dependency, any direct usages of setContent as well as internal usages by androidx.compose.ui:ui-tooling:1.0.0-alpha12 or androidx.compose.ui:ui-test-junit4:1.0.0-alpha12 will use the fixed Activity Compose 1.3.0-alpha02 release.
