compileSdkVersion is not specified. Please add it to build.gradle: even though I have it defined in my build.gradle file

I tried adding the openweather api and when I try to sync the build.gradle file this error pops up
compileSdkVersion is not specified. Please add it to build.gradle
My File:
plugins {
id 'com.android.application'
id 'org.jetbrains.kotlin.android'
}
android {
namespace 'com.example.myapplication'
compileSdk 33
defaultConfig {
applicationId "com.example.myapplication"
minSdk 24
targetSdk 33
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
}
kotlinOptions {
jvmTarget = '1.8'
}
}
dependencies {
implementation 'androidx.core:core-ktx:1.7.0'
implementation 'androidx.appcompat:appcompat:1.6.0'
implementation 'com.google.android.material:material:1.7.0'
implementation 'androidx.constraintlayout:constraintlayout:2.1.4'
testImplementation 'junit:junit:4.13.2'
androidTestImplementation 'androidx.test.ext:junit:1.1.5'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.5.1'
}
I already have CompileSDK defined so idk why this still pops up.

This error defines that you haven’t mentioned compileSdkVersion and not compileSdk. Although both means same but still if you are facing this issue mention compileSdkVersion in the build.gradle file.
This issue is relates with the new gradle changes in 7.0.0 so you can use compileSdkVersion with string and with int values like below.
android {
compileSdkVersion = "S"
//or with same number version
}

Why android studio 3, show me this error?

somebody can tell me, why Android Studio 3.0.1, show me this error when make app?
Execution failed for task ':joy-android-game-gdx:transformDexArchiveWithExternalLibsDexMergerForDebugAndroidTest'.
> java.lang.RuntimeException: com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex
The next attach *my build gradle**
apply plugin: 'com.android.application'
android {
compileSdkVersion 25
buildToolsVersion '26.0.2'
defaultConfig {
applicationId "com.websmithing.gpstracker"
minSdkVersion 15
targetSdkVersion 25
versionCode 15
versionName "4.0.5"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:25.0.0'
compile 'com.google.android.gms:play-services:9.8.0'
compile 'com.loopj.android:android-async-http:1.4.9'
}
the app compila when i delete this line:
compile 'com.android.support:appcompat-v7:25.0.0'
but the app after moment automatic close

Try
apply plugin: 'com.android.application'
android {
compileSdkVersion 25
buildToolsVersion '25.0.0'
defaultConfig {
applicationId "com.websmithing.gpstracker"
minSdkVersion 15
targetSdkVersion 25
versionCode 15
versionName "4.0.5"
multiDexEnabled true
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:25.0.0'
compile 'com.google.android.gms:play-services:9.8.0'
compile 'com.loopj.android:android-async-http:1.4.9'
compile 'com.android.support:multidex:1.0.2'
}
Beside this, please review your dependency versions. They are not the latest versions and you might want to update them. Take care of the buildToolsVersion as well.

Android studio plain java library proguard

Is it possible to have different build types for plain java libraries in Android Studio with gradle? My intention is to run proguard and minify the jar file size.
Java build.gradle
apply plugin: 'java'
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
testCompile 'junit:junit:4.12'
}
Android build.gradle
android {
compileSdkVersion 23
buildToolsVersion '23.0.2'
defaultConfig {
applicationId "test.app"
minSdkVersion 23
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
packagingOptions {
exclude 'META-INF/services/javax.annotation.processing.Processor'
exclude 'META-INF/NOTICE.txt'
exclude 'META-INF/LICENSE.txt'
}
productFlavors {
buildWithSingleAlarmFlavour {
applicationId "test.app"
versionName ".1"
}
buildWithMultipleAlarmFlavour {
applicationId "test.app"
versionName "0.1"
}
}
}

Android Error Regarding MultiDex

I'm getting the following error when I build my application in Android:
Error:Execution failed for task ':app:packageAllDebugClassesForMultiDex'.
java.util.zip.ZipException: duplicate entry: oauth/signpost/http/HttpResponse.class
My build.gradle looks like this:
apply plugin: 'com.android.application'
android {
compileSdkVersion 22
buildToolsVersion "22.0.1"
defaultConfig {
applicationId "com.example.me.hey"
minSdkVersion 8
targetSdkVersion 22
versionCode 1
versionName "1.0"
multiDexEnabled = true
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
compile 'com.android.support:appcompat-v7:22.2.0'
compile 'com.semantics3:Sem3Java:1.2.2'
compile files('libs/Sem3Java-1.2.2-jar-with-dependencies.jar')
compile 'com.android.support:multidex:1.0.0'
}
Any ideas on what I might be doing wrong?

Coverage report says zero coverage on android with gradle

I've been unable to get code coverage to work on any of my android projects.
To simplify things I created a new project (selected empty activity).
Added a new utility class to the the project in src/main/java.
I then created a unit test for it in src/androidTest/java.
Updated the gradle file to enable coverage.
apply plugin: 'com.android.application'
android {
compileSdkVersion 21
buildToolsVersion "21.1.2"
defaultConfig {
applicationId "com.example.michaelkrussel.coverageapp"
minSdkVersion 15
targetSdkVersion 21
versionCode 1
versionName "1.0"
}
jacoco {
version "0.7.1.201405082137"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
debug {
testCoverageEnabled true
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.3'
}
I ran the tests then using ./gradlew createDebugCoverageReport. The unit test shows that the test I created passed, but the coverage report reports zero coverage.
I assume I'm either missing something in the gradle file or not running the correct gradle task, but I cannot figure out what.

I'm using this configuration in my project and work fine!
apply plugin: 'com.android.application'
android {
compileSdkVersion 21
buildToolsVersion "21.1.1"
defaultConfig {
applicationId "br.com.acs.app"
minSdkVersion 18
targetSdkVersion 21

testApplicationId "br.com.acs.app.test"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
debug {
testCoverageEnabled true
}
}
packagingOptions {
exclude 'LICENSE.txt'
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.3'
androidTestCompile 'junit:junit:4.11'
androidTestCompile('com.android.support.test:testing-support-lib:0.1') {
exclude group: 'junit'
}
}
