After fixing "Android Gradle plugin requires Java 11 to run. You are currently using Java 1.8" Android studio emulator still doesn't work

Regards this type of issue we can create a demo to check the configuration.

For an instance, I created a demo with Empty Activity and using Kotlin.

The configuration looks like this:

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

android {
    compileSdkVersion 30
    buildToolsVersion "30.0.3"

    defaultConfig {
        applicationId "com.example.teststackoverflow"
        minSdkVersion 21
        targetSdkVersion 30
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }

// Please check this
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

// Please check this
    kotlinOptions {
        jvmTarget = '1.8'
    }
}

And we also need to check the configuration on the menu of Project Structure I always used the Embedded JDK which is in location of Android Sutido
Of course， you can specify other JDK you want to use.
