I'm having a issue implement Hilt on android app...
The error is:
Expected #HiltAndroidApp to have a value. Did you forget to apply the Gradle Plugin?
Project gradle file
buildscript {
repositories {
google()
mavenCentral()
}
dependencies {
//Hilt
classpath 'com.google.dagger:hilt-android-gradle-plugin:2.38.1'
classpath "com.android.tools.build:gradle:7.0.4"
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.5.20"
}
}
Model gradle file
id 'kotlin-kapt'
id 'dagger.hilt.android.plugin'
dependencies {
def dagger_hilt_android = "2.38.1"
implementation("com.google.dagger:hilt-android:$dagger_hilt_android")
kapt("com.google.dagger:hilt-android-compiler:$dagger_hilt_android")
}
It is an issue with Kotlin-gradle-plugin: 1.5.20 as mentioned here https://github.com/google/dagger/issues/2684. Try upgrading your plugin to 1.5.21, and it will work.
Mohmd.h.bh,
Try applying this plugin in your build.gradle of your Android Gradle
apply plugin: 'com.google.dagger.hilt.android'
android {
// .......
}
I don't think you need to change the version of the kotlin-gradle-plugin
Regards
When I am using Hilt in android with Room I got this kinda error.
The full log is here:
home/someone/Desktop/Calculator/app/build/tmp/kapt3/stubs/debug/com/hamidjonhamidov/calculator/MyApplication.java:7: error: [Hilt]
public class MyApplication extends android.app.Application {

Expected #HiltAndroidApp to have a value. Did you forget to apply the Gradle Plugin?
[Hilt] Processing did not complete. See error above for details./home/someone/Desktop/Calculator/app/build/tmp/kapt3/stubs/debug/com/hamidjonhamidov/calculator/ui/main/MainActivity.java:7: error: [Hilt]
Anyone knows solution for this?
I had this issue after upgrading Kotlin to 1.5.20.
Adding kapt.use.worker.api=false in gradle.properties worked for me the problem
Checkout dagger issue Support for Kotlin 1.5.20
Fortunately, there is simple solution.
In build.gradle in database scheme, we should use arguments += instead of arguments = .
defaultConfig{
javaCompileOptions {
annotationProcessorOptions {
arguments += ["room.schemaLocation": "$projectDir/schemas".toString()]
}
}
}
Or/And in buld.gradle
You should apply plugin like:
apply plugin 'dagger.hilt.android.plugin'
This solved the problem)
UPDATE
Upgrade Hilt to v28.1.0 and Kotlin to v1.5.21 should fix this issue
OLD ANSWER
If you are on kotlin 1.5.20, answer of Mr-wil will decrease build speed as said in official doc:
To improve the speed of builds that use kapt, you can enable the
Gradle worker API for kapt tasks. Using the worker API lets Gradle run
independent annotation processing tasks from a single project in
parallel, which in some cases significantly decreases the execution
time.
Instead, set:
kapt {
javacOptions {
// These options are normally set automatically via the Hilt Gradle plugin, but we
// set them manually to workaround a bug in the Kotlin 1.5.20
option("-Adagger.fastInit=ENABLED")
option("-Adagger.hilt.android.internal.disableAndroidSuperclassValidation=true")
}
}

This generic error message can also appear in many circumstances. As a more generic check, ensure that your module's build.gradle file, ensure that you has:
apply plugin: 'dagger.hilt.android.plugin'
at the top.
This was due to a bug in Kotlin 1.5.20. It is fixed in Kotlin 1.5.21.
So all you need to do is to upgrade to the latest version of Kotlin.
I had the same problem and it seems like there is a problem in kotlin-kapt plugin. If you guys have tried out all the above answers and didn't get resolved, please try the below code in your build.gradle(module-level) outside the dependencies{} block
kapt {
javacOptions {
option("-Adagger.hilt.android.internal.disableAndroidSuperclassValidation=true")
}
}
in the build.gradle of your Android Gradle modules apply the plugin:
apply plugin: 'com.android.application'
apply plugin: 'dagger.hilt.android.plugin'
android {
// ...
}
see detail here
I'm still facing the same issue in 2022
I have solved the problem by adding
classpath 'com.google.dagger:hilt-android-gradle-plugin:2.38.1'
to build.gradle project and adding
id 'dagger.hilt.android.plugin'
to plugins in build.gradle app
In my case it solved by declaring plugin:
plugins {
id("dagger.hilt.android.plugin")
}
Check if all these are added.In my case I had missed adding one of the below line.
In project level build.gradle
buildscript {
dependencies {
classpath "com.google.dagger:hilt-android-gradle-plugin:2.44"
}
}
In app level build.gradle
plugins {
id 'com.android.application'
id 'org.jetbrains.kotlin.android'
id 'kotlin-kapt'
id 'dagger.hilt.android.plugin'
}
dependencies {
implementation "com.google.dagger:hilt-android:2.44"
implementation "androidx.hilt:hilt-common:1.0.0"
kapt "com.google.dagger:hilt-android-compiler:2.44"
}
-In app level build.gradle---add the following in newer versions
plugins {
id 'com.android.application'
id 'org.jetbrains.kotlin.android'
id 'kotlin-android'
id 'kotlin-kapt'
id 'dagger.hilt.android.plugin'
}
In project level build.gradle
buildscript {
ext.kotlin_version = "1.7.21"
repositories {
google()
mavenCentral()
}
dependencies {
classpath "com.android.tools.build:gradle:4.2.2"
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
classpath 'com.google.dagger:hilt-android-gradle-plugin:2.42'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
I am getting this Error while updating one signal Dependency.
how can I rectify this??
Dependency failing: com.onesignal:OneSignal:3.12.6 -> com.google.android.gms:play-services-base#[10.2.1, 16.1.99], but play-services-base version was 17.1.0.
In your app/build.gradle where you applied the plugin
apply plugin: 'com.onesignal.androidsdk.onesignal-gradle-plugin'
make sure its is before
apply plugin: "com.android.application"
Android studio also gives a warning if the order of the above statements is not correct.
I was missed out updating the classpath in dependencies
dependencies {
classpath 'gradle.plugin.com.onesignal:onesignal-gradle-plugin:[0.12.6, 0.99.99]
}
Is it possible to use kotlin-allopen gradle plugin for android testing with mockito?
I've tried to add kotlin-allopen plugin to my build.gradle and define the annotation.
buildscript {
ext.kotlin_version = '1.0.6'
dependencies {
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
classpath "org.jetbrains.kotlin:kotlin-allopen:$kotlin_version"
}
}
apply plugin: 'com.android.application'
apply plugin: 'kotlin-allopen'
apply plugin: 'kotlin-android'
allOpen {
annotation("com.mycompany.OpenForTest")
}
And these for annotation itself
annotation class OpenForTest
It's not working for me. Maybe I miss something?
Yes you can.
Because it's a compiler plugin, you'll get all-open code after compilation.
So it should work with tests.
Don't worry.
Edit: according to the comment area, updating the kotlin plugin version seems work. Currently the newest version is 1.2.41.
First add the dependency in your build.gradle (project) file:
dependencies {
classpath "org.jetbrains.kotlin:kotlin-allopen:$kotlin_version"
}
After that apply the plugin in your build.gradle (app mobdule) file:
apply plugin: 'kotlin-allopen'
Then specify the list of annotations that will make classes open:
allOpen {
annotation('com.example.myproject.OpenForTesting')
}
And use this annotation for every class which you want to be open
#OpenForTesting
Here is the Kotlin official documentation about All-open: https://kotlinlang.org/docs/reference/compiler-plugins.html
Hope this help
i want to add
https://github.com/gabrielemariotti/cardslib
but android studio give me this error :
Error:(9, 0) Cause: cannot get property 'compileSdkVersion' on extra properties extension as it does not exist
The best way to use this library with Andriod Studio is to add this dependency in your build.gradle
dependencies {
compile 'com.github.gabrielemariotti.cards:library:1.9.1'
}
If you want to clone locally you should check the top level build.gradle (in the root) inside the github repo.
It sets some variables, and you have to add these parts in your top level build.gradle
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:0.12.2'
classpath 'com.jakewharton.sdkmanager:gradle-plugin:0.12.0'
}
}
ext {
compileSdkVersion = 19
buildToolsVersion = "20.0.0"
}
I had same problem with ChangeLog Library.(https://github.com/gabrielemariotti/changeloglib)
I thought there is no need for applying android-sdk-manager plugin for a library, android library plugin is enough. So i removed android-sdk-manager plugin from build.gradle left only android library plugin like below.
Change this:
apply plugin: 'android-sdk-manager'
apply plugin: 'com.android.library'
to this:
apply plugin: 'com.android.library'
It worked without any problem in my case. I hope it will help someone else too.
