Issues building the app with Android Studio Hedgehog

[leopic]

Hey folks, I just started with this lesson and I had a lot of issues getting the app build. I initially checked out the starter-code and went down a rabbit hole trying it to get the build and eventually gave up.

A coworker helped me and got the master branch to run, but I had to tweak both the compileSdkVersion and targetSdkVersion to version 34, up from 31

Android Studio info:

Android Studio Hedgehog | 2023.1.1 Patch 1
Build #AI-231.9392.1.2311.11255304, built on December 26, 2023
Runtime version: 17.0.7+0-17.0.7b1000.6-10550314 aarch64

Registry:
    external.system.auto.import.disabled=true
    ide.text.editor.with.preview.show.floating.toolbar=false

Non-Bundled Plugins:
    com.github.copilot (1.4.4.3955)
    google-java-format (1.17.0.0)
    idea.plugin.protoeditor (231.9225.5)

I was using JDK 17, the one bundled with Android Studio.

However the starter-code branch fails, from the get go, with this error:

Unsupported Java. 
Your build is currently configured to use Java 17.0.7 and Gradle 6.1.1.

Possible solution:
 - Upgrade Gradle wrapper to 7.2 version and re-import the project

Diffing between master and this branch helps, but without some Git-foo and my colleague's help it would have been a nightmare to get this to run.

Here are some fixes I applied to the gradle files:

Build gradle (project):

buildscript {

        ext {
//update kotlin version, I use 1.8.0
            kotlin_version = "1.8.0"
        }
    repositories {
        google()
        mavenCentral()
    }
    dependencies {

> 
//Update gradle classpath
        classpath 'com.android.tools.build:gradle:8.1.1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        mavenCentral()
    }
}

tasks.register('clean', Delete) {
    delete rootProject.buildDir
}

Build gradle (:app):

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'

// apply plugin: 'kotlin-android-extensions'

android {

// Not sure if these compile options are actually necessary
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_17
        targetCompatibility JavaVersion.VERSION_17
    }
    kotlinOptions {
        jvmTarget = '17'
    }

// UPdate the targetSdkVersion and compileSdkVersion
    compileSdkVersion 34
    defaultConfig {
        applicationId "com.example.android.dessertpusher"
        minSdkVersion 19
        targetSdkVersion 34
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
        vectorDrawables.useSupportLibrary = true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    buildFeatures {
        dataBinding true
    }
    productFlavors {
    }
//Set the namespace
    namespace 'com.example.android.dessertpusher'
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'androidx.appcompat:appcompat:1.6.1'
    implementation 'androidx.constraintlayout:constraintlayout:2.1.4'
    implementation 'com.jakewharton.timber:timber:4.7.1'
}

Make sure the gradle version you have installed (in my case 8.0) matches your file

gradle wrapper properties:

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/_gradle-8.0-bin.zip_
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists

Make sure to set android:exported="true" as this is required with the updated versions.

Android Manifest.xml:

   <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_dessert_pusher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_dessert_pusher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity"
            android:exported="true">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

Hey, had the same issue few months ago and submitted a PR to fix it, but it hasn't been merged. Here's the pull request fixing this. Can repo owners look into merging it? https://github.com/udacity/andfun-kotlin-dessert-pusher/pull/26
