Gradle同步失败报错：无法解析androidx.activiy:activity-ktx:1.9.0

核心问题：依赖拼写错误 #

错误提示Failed to resolve: androidx.activiy:activity-ktx:1.9.0的直接原因是依赖组名拼写错误——androidx.activiy少了一个字母t，正确组名为androidx.activity。此外配置中还存在依赖重复定义、libs依赖项冗余的问题，以下是具体修复步骤：

1. 修复libs.versions.toml的拼写错误并清理冗余 #

打开项目根目录下的libs.versions.toml，删除错误条目并统一版本：

• 移除拼写错误的androidx-activity-ktx条目
• 删除冗余的activityKtx版本定义，统一用activity版本关联activity-ktx

修改后的完整libs.versions.toml：

[versions]
agp = "8.6.1"
kotlin = "1.9.0"
coreKtx = "1.13.1"
junit = "4.13.2"
junitVersion = "1.2.1"
espressoCore = "3.6.1"
appcompat = "1.7.0"
lifecycleRuntimeKtx = "2.8.6"
material = "1.12.0"
activity = "1.9.2"
constraintlayout = "2.1.4"
roomRuntime = "2.6.1"

[libraries]
activity-ktx = { module = "androidx.activity:activity-ktx", version.ref = "activity" }
androidx-core-ktx = { group = "androidx.core", name = "core-ktx", version.ref = "coreKtx" }
androidx-lifecycle-runtime-ktx = { module = "androidx.lifecycle:lifecycle-runtime-ktx", version.ref = "lifecycleRuntimeKtx" }
androidx-lifecycle-viewmodel-ktx = { module = "androidx.lifecycle:lifecycle-viewmodel-ktx", version.ref = "lifecycleRuntimeKtx" }
androidx-room-compiler = { module = "androidx.room:room-compiler", version.ref = "roomRuntime" }
androidx-room-ktx = { module = "androidx.room:room-ktx", version.ref = "roomRuntime" }
androidx-room-runtime = { module = "androidx.room:room-runtime", version.ref = "roomRuntime" }
junit = { group = "junit", name = "junit", version.ref = "junit" }
androidx-junit = { group = "androidx.test.ext", name = "junit", version.ref = "junitVersion" }
androidx-espresso-core = { group = "androidx.test.espresso", name = "espresso-core", version.ref = "espressoCore" }
androidx-appcompat = { group = "androidx.appcompat", name = "appcompat", version.ref = "appcompat" }
material = { group = "com.google.android.material", name = "material", version.ref = "material" }
androidx-activity = { group = "androidx.activity", name = "activity", version.ref = "activity" }
androidx-constraintlayout = { group = "androidx.constraintlayout", name = "constraintlayout", version.ref = "constraintlayout" }

[plugins]
androidApplication = { id = "com.android.application", version.ref = "agp" }
jetbrainsKotlinAndroid = { id = "org.jetbrains.kotlin.android", version.ref = "kotlin" }

2. 清理应用级build.gradle.kts的重复依赖 #

打开app/build.gradle.kts，删除重复依赖项，确保每个依赖仅引用一次，并修正activity-ktx的引用：

修改后的dependencies块：

dependencies {
    val room_version = "2.6.1"
    implementation(libs.androidx.core.ktx)
    implementation(libs.androidx.appcompat)
    implementation(libs.material)
    implementation(libs.androidx.activity)
    implementation(libs.activity-ktx)
    implementation(libs.androidx.constraintlayout)
    implementation(libs.androidx.lifecycle.runtime.ktx)
    implementation(libs.androidx.lifecycle.viewmodel.ktx)
    implementation(libs.androidx.room.runtime)
    kapt(libs.androidx.room.compiler)
    implementation(libs.androidx.room.ktx)

    testImplementation(libs.junit)
    androidTestImplementation(libs.androidx.junit)
    androidTestImplementation(libs.androidx.espresso.core)
}

3. 同步Gradle #

完成修改后，点击Android Studio右上角的Sync Project with Gradle Files按钮，等待同步完成即可解决依赖解析失败问题。
