You can open this sample inside a Android Studio IDE using the project importer.

This sample shows how a simple Android application written in Java can be built with Gradle. The application was created following the Build your first app guide.

app/build.gradle.kts
plugins {
    id("com.android.application") version "8.3.0"
}

repositories {
    google()
    mavenCentral()
}

android {
    compileSdk = 30
    defaultConfig {
        applicationId = "org.gradle.samples"
        namespace = "org.gradle.samples"
        minSdk = 16
        targetSdk = 30
        versionCode = 1
        versionName = "1.0"
        testInstrumentationRunner = "androidx.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        getByName("release") {
            isMinifyEnabled = false
            proguardFiles(getDefaultProguardFile("proguard-android-optimize.txt"), "proguard-rules.pro")
        }
    }
}

dependencies {
    implementation("androidx.appcompat:appcompat:1.2.0")
    implementation("com.google.android.material:material:1.2.0")
    implementation("androidx.constraintlayout:constraintlayout:2.0.4")
    testImplementation("junit:junit:4.13.1")
    androidTestImplementation("androidx.test.ext:junit:1.1.2")
    androidTestImplementation("androidx.test.espresso:espresso-core:3.3.0")
}
app/build.gradle
plugins {
    id('com.android.application') version '8.3.0'

repositories {

    mavenCentral()

android {
    compileSdk = 30
    defaultConfig {
        applicationId = 'org.gradle.samples'
        namespace = 'org.gradle.samples'
        minSdk = 16
        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')
        }
    }
}

dependencies {
    implementation 'androidx.appcompat:appcompat:1.2.0'
    implementation 'com.google.android.material:material:1.2.0'
    implementation 'androidx.constraintlayout:constraintlayout:2.0.4'
    testImplementation 'junit:junit:4.13.1'
    androidTestImplementation 'androidx.test.ext:junit:1.1.2'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'
}

To build the application:

$ ./gradlew build
