我正在使用 jetpack compose 启动一个简单的基础项目Android Studio 2020.3.1 金丝雀 15。我遵循了这个指南https://developer.android.com/jetpack/compose/setup https://developer.android.com/jetpack/compose/setup添加了所需的依赖项,我还将它们更新为最新的beta06
因为它显示了警告。
现在,我运行时出现以下错误:
org.jetbrains.kotlin.codegen.CompilationException: Back-end (JVM) Internal error: Couldn't inline method call 'Column' into
local final fun <anonymous>(): kotlin.Unit defined in <packagename>.onCreate
{
Column(
modifier = Modifier.fillMaxSize(),
verticalArrangement = Arrangement.Center,
horizontalAlignment = Alignment.CenterHorizontally
) {
}
}
Cause: Not generated

My MainActivity
发生错误的代码:
import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import androidx.activity.compose.setContent
import androidx.compose.foundation.layout.Arrangement
import androidx.compose.foundation.layout.Column
import androidx.compose.foundation.layout.fillMaxSize
import androidx.compose.material.CircularProgressIndicator
import androidx.compose.material.Text
import androidx.compose.ui.Alignment
import androidx.compose.ui.Modifier
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContent {
Column(
modifier = Modifier.fillMaxSize(),
verticalArrangement = Arrangement.Center,
horizontalAlignment = Alignment.CenterHorizontally
) {
}
}
}
}
我已经尝试过这个:java.lang.AssertionError:CALL 'public final fun https://stackoverflow.com/questions/65462221/java-lang-assertionerror-call-public-final-fun-get-currentcomposer
还有其他这样的答案,但没有一个对我有用。
任何帮助深表感谢。谢谢。
