我在初始化Google Mobile Ads SDK时遇到问题

Question

我想把谷歌广告添加到我的Android移动应用程序中。所以我经历了以下步骤：https://developers.google.com/admob/android/quick-start?hl=de#kotlin

我的问题：

1-当我将谷歌移动广告SDK的依赖项添加到模块的应用程序级渐变文件时，通常是应用程序/构建。格拉德尔：

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'com.google.android.gms:play-services-ads:20.5.0' }

我得到以下错误

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:checkDebugAarMetadata'.
> A failure occurred while executing com.android.build.gradle.internal.tasks.CheckAarMetadataWorkAction
   > The minCompileSdk (31) specified in a
     dependency's AAR metadata (META-INF/com/android/build/gradle/aar-metadata.properties)
     is greater than this module's compileSdkVersion (android-30).
     Dependency: androidx.work:work-runtime:2.7.0.
     AAR metadata file: C:\Users\moham\.gradle\caches\transforms-2\files-2.1\6ca6bfbb6ed79157a08fdd6548cc9e4d\work-runtime-2.7.0\META-INF\com\android\build\gradle\aar-metadata.properties.

2-当我想初始化谷歌移动广告SDK在MainActivity.kt我得到以下错误

e: C:\Users\moham\flutter\zwei\android\app\src\main\kotlin\com\example\zwei\MainActivity.kt: (4, 12): Unresolved reference: google
e: C:\Users\moham\flutter\zwei\android\app\src\main\kotlin\com\example\zwei\MainActivity.kt: (6, 22): Unresolved reference: AppCompatActivity

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:compileDebugKotlin'.
> Compilation error. See log for more details

3-当我将compileSdkVersion更新到32时，我收到此错误：

e: C:/Users/moham/.gradle/caches/transforms-2/files-2.1/683fded33b117c0eb9bb9deabca1a71e/work-runtime-2.7.0-api.jar!/META-INF/work-runtime_release.kotlin_module: Module was compiled with an incompatible version of Kotlin. The binary version of its metadata is 1.5.1, expected version is 1.1.15.

4-当我更新我的主要活动时。kt来自：

package com.example.zwei

import io.flutter.embedding.android.FlutterActivity

class MainActivity: FlutterActivity() {
}

为此：

package com.example.zwei

import io.flutter.embedding.android.FlutterActivity
import com.google.android.gms.ads.MobileAds

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        MobileAds.initialize(this) {}
    }
}

我犯了很多错误

我应该如何解决这些错误？

Answer 1

这次仔细看了错误。

Soln（1）：尝试将CompileSDK版本更新为31或32。如果错误仍然存在，请告诉我。

​ Android​

Soln（2）：另一种方法是实际上将库“降级”到不需要SDK版本的阶段

执行Soln（1）后，执行以下操作：ext.kotlin_version='1.4.32'（或可用的最新版本）

（应该可以解决您在评论中提到的错误）
