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.

首先，我使用的 setContent 方法显示为已弃用.

摘录自 Alpha 12发行说明，我注意到它说:

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

因此，我删除了 import androidx.compose.ui.platform.setContent ，并将其切换为 import androidx.activity.compose.setContent ，从而删除了弃用项./p>

但是，我然后看到一条错误消息:

  w:此版本的编译器不支持标志:-Xallow-jvm-ir-dependenciesw:注意！此版本使用不安全的内部编译器参数:-XXLanguage:+ NonParenthesizedOnFunctionalTypes上的注释不建议将此模式用于生产环境，因为没有提供稳定性/兼容性保证编译器或生成的代码.需要您自担风险使用它！e:在依赖项中发现了由不稳定版本的Kotlin编译器编译的类.从类路径中删除它们，或使用"-Xallow-unstable-dependencies"抑制错误e:/[我的路径]/MainActivity.kt:(39，9):类'androidx.activity.compose.ComponentActivityKt'是由不稳定版本的Kotlin编译器编译，因此无法由该编译器加载 

再次，我可以通过将 build.gradle 文件更改为具有以下方法来解决此问题:

  kotlinOptions {jvmTarget ='1.8'useIR = true//我添加了这一行freeCompilerArgs + ="-Xallow不稳定依赖性"；} 

虽然可以编译我的应用程序，但现在在运行时出现以下异常:

  java.lang.NoSuchMethodError:没有静态方法setContent(Landroidx/activity/ComponentActivity; Landroidx/compose/runtime/CompositionContext; Lkotlin/jvm/functions/Function2;)V in classLandroidx/活动/撰写/ComponentActivityKt;或它的超类("androidx.activity.compose.ComponentActivityKt"的声明出现在[我的apk]中 

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

解决方案

根据此问题，此问题与新的 androidx.activity:activity-compose:1.3.0-alpha01 工件有关.

从该问题开始:

活动 1.3.0-alpha02 已发布并解决了此问题.

使用Compose alpha12的应用，尤其是内部使用 setContent 的工件(例如 androidx.compose.ui:ui-test-junit4:1.0.0-alpha12 )应添加 activity-compose:1.3.0-alpha02 依赖于其 dependencies 块，以确保不使用 1.3.0-alpha01 工件

因此，要修复您的应用，您应该:

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

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

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

通过添加该依赖关系， setContent 的任何直接用法以及 androidx.compose.ui:ui-tooling:1.0.0-alpha12 或 androidx.compose.ui:ui-test-junit4:1.0.0-alpha12 将使用固定的Activity Compose 1.3.0-alpha02版本.

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

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

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

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

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

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

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"
}

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]

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

解决方案

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

From that issue:

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

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

So to fix your app, you should:

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

2. Add a specific dependency on Activity Compose 1.3.0-alpha02:

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

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.
