检查 AAR 元数据值时发现的一个或多个问题：

Question

嘿，我正在尝试运行我的应用程序，但我收到了这个错误

build.gradle

plugins {
    id 'com.android.application'
    id 'kotlin-android'
    id 'kotlin-kapt'
}

android {
    compileSdk 30

    configurations.all {
        resolutionStrategy { force 'androidx.core:core-ktx:1.7.0-alpha01' }
    }

    defaultConfig {

        applicationId "com.example.listadapter"
        minSdk 21
        targetSdk 30
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
    kotlinOptions {
        jvmTarget = '1.8'
    }

    buildFeatures {
        viewBinding true
    }
}

dependencies {

    implementation 'androidx.core:core-ktx:1.7.0'
    implementation 'androidx.appcompat:appcompat:1.3.1'
    implementation 'com.google.android.material:material:1.4.0'
    implementation 'androidx.constraintlayout:constraintlayout:2.1.1'
    testImplementation 'junit:junit:4.+'

    implementation "android.arch.lifecycle:extensions:1.1.1"
    implementation 'androidx.fragment:fragment-ktx:1.3.6'
}

我尝试了这个中的所有示例，它不起作用

安装应用程序后出现错误。我刚刚创建了一个新的应用程序。我不明白为什么会这样。有谁知道如何解决这个问题？提前致谢。

如果我更改我的 compileSdk 31 它会给我另一个错误。

Answer 1

依赖关系：androidx.lifecycle:lifecycle-runtime-ktx:2.4.0。问题在于这种依赖性，可能存在一些传递依赖性错误。我建议使用此依赖项的 alpha 版本，对我有用。替换为此依赖项：androidx.lifecycle:lifecycle-*:2.4.0-alpha03

Answer 2

这是因为您刚刚升级了 Kotlin。

打开SDK Manager，安装Android12(API31)或以上，然后将compileSdkVersion改为31(或以上)，将targetSdkVersion改为31(或以上)。

那么你还需要将 minSdkVersion 更改为 19。

Answer 3

compileSdk和targetSdk都应该是31，你试过了吗？

Answer 4

将您的 compileSdk 30 更改为 31。

对我有用！

   compileSdk 31

    defaultConfig {
        applicationId "com.example.lifecycle"
        minSdk 21
        targetSdk 30
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

Answer 5

改变你的compileSdk 30 to 31.

就是这样。享受你的编码...
