Error in my flutter project after trying to change sdk target

Question

I can't run my app anymore since i tried to change the target sdk from 33 to 34. Now even when I change it back I get the same error:

---

FAILURE: Build failed with an exception.

• Where: Build file 'C:\Users\dicov\Downloads\Flutter-Dating-App-master\android\build.gradle' line: 28

• What went wrong: A problem occurred evaluating root project 'android'. A problem occurred configuring project ':app'. Failed to notify project evaluation listener. > 'com.android.build.api.variant.SourceDirectories$Flat com.android.build.api.variant.Sources.getByName(java.lang.String)'

This is my build.gradle

    id "kotlin-android"
    id "dev.flutter.flutter-gradle-plugin"
    id "com.google.gms.google-services"
}
def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
    localPropertiesFile.withReader('UTF-8') { reader ->
        localProperties.load(reader)
    }
}
def keystoreProperties = new Properties()
def keystorePropertiesFile = rootProject.file('key.properties')
if (keystorePropertiesFile.exists()) {
    keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
}


def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
    flutterVersionCode = '1'
}

def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
    flutterVersionName = '1.0'
}



android {
    compileSdkVersion 34
    ndkVersion flutter.ndkVersion

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8

    }

    defaultConfig {

    }

    signingConfigs {
        release {
            keyAlias keystoreProperties['keyAlias']

    }

}

flutter {
    source '../..'
}

dependencies {

    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:1.8.22"
    implementation 'com.google.android.gms:play-services-ads:23.1.0'

And this my manifest:

This is my build.gradle android level:

buildscript {
    ext.kotlin_version = '2.0.0'
    repositories {
        google()
        mavenCentral()

    }

    dependencies {
        classpath 'com.android.tools.build:gradle:7.4.2'
        classpath 'com.google.gms:google-services:4.4.2'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.9.0"
    }
}

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

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
    project.evaluationDependsOn(':app')
}

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

And the android SDK upgrade assistant isn't helping me either, I do everything it says and it still doesn't verify the components I did do to upgrade my SDK from 33 to 34.

Can anyone please help me, thank you.

Answer 1

Please add the target sdk version and compileSdkVersion 33 to 34. after open the project android folder for android studio and upgrade your all the gradel and kotline version.
