Pedram Davoodi :
I'm new to android and I build my first test project in android studio but get this error
Java compiler
error: annotations are not supported in -source 1.3
(use -source 5 or higher to enable annotations)
how should i fix it?
And this is my gradle
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
ext.kotlin_version = '1.3.50'
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.5.0'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
classpath "org.jetbrains.kotlin:kotlin-android-extensions:$kotlin_version"
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir

I also had the same issue, the problem was that mysourceCompatibility and targetCompatibility in compileOptions were pointing to kotlin_version set them to your correct java versions in your project level build.gradle file.
android {
compileSdkVersion 28
defaultConfig {
applicationId "x.y.z"
minSdkVersion 22
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
compileOptions {
sourceCompatibility = JavaVersion.VERSION_1_8
targetCompatibility = JavaVersion.VERSION_1_8
}
buildToolsVersion = '28.0.3'
}
