Dagger 2 : Cannot resolve symbol for dagger component

cannot resolve symbol daggerappcomponent
dagger cannot find symbol
cannot resolve symbol daggerapplicationcomponent
daggerappcomponent not generated kotlin
dagger component generate
dagger 2 android
dagger 2 java example
error cannot find symbol import dagger internal inject field signature

I would like to exercise this Dagger 2 Vehicle Motor example.

I made everything exact like in that tutorial, except for my gradel.build:

compile 'com.google.dagger:dagger:2.4'
apt 'com.google.dagger:dagger-compiler:2.4'
compile 'javax.annotation:javax.annotation-api:1.2'

but then I get an

error: cannot find symbol variable Dagger_VehicleComponent

Whats wrong there? (Same without '_' underscore)

Another version solved it:

compile 'com.google.dagger:dagger:2.2'
apt 'com.google.dagger:dagger-compiler:2.2'
provided 'javax.annotation:jsr250-api:1.0'

cannot resolve symbol DaggerAppComponent #1. Closed. bananaCaptain component = DaggerAppComponent.builder(). https://github.com/erikcaffrey/​Dagger2-MVP-Sample/blob/master/app/build.gradle#L38 to "apt  // Dagger component val component = daggerInjection(testApp!!) testApp.setTestComponent(component) // Dagger shot: init all variables component.inject(this) Sign up for free to join this conversation on GitHub .

  1. Change Dagger_VehicleComponent with DaggerVehicleComponent
  2. Clean and rebuild your project
  3. Import DaggerVehicleComponent class

I can not compile code. It gives Cannot resolve symbol '​DaggerVehicleComponent ' error. My build.gradle: compile 'com.google.dagger:​dagger:2.0.2' provided  Functionality wise Dagger 1 and 2 are similar, but the major advantage of 2.0 is the removal of reflection, thus bringing a speed up in injection and also allows the use of proguard. The generated source is human-readable and supposedly debuggable.

Took me a while to figure this out. But I found the reason (At least on my side) I created a project from scratch, after that I was trying to set up the basic components/tools till I bump into this issue.

Reading other answers I found that DaggerApplicationComponent class is autogenerated by the compiler, then I thought, why the IDE can't "find" this class? The answer is obvious and... you got it, was because the project wasn't compiling, here are the steps to solve this issue if the scenario is the same as mine.

1) Open terminal and go to your projects path (Or simply open the terminal in the Android Studio)

2) Clean project ./gradlew clean

3) Build the project ./gradlew build

NOTE: If by this point you have noticed the project is not compiling... Bingo! That might be the real issue. Then follow the next steps:

4)Open gradle and add the buildToolsVersion '23.0.1' and very IMPORTANT has to be enabled multiDexEnabled true This is how my gradle in the app module looks like

android {
    buildToolsVersion '23.0.1' // IMPORTANT
    compileSdkVersion 26
    defaultConfig {
        applicationId "com.fixing.dagger"
        minSdkVersion 23
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        multiDexEnabled true  // ALSO IMPORTANT

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

After that you will be able to import the DaggerApplicationComponent.

Hope this saves time for someone else!

Ignore the Cannot resolve symbol error; DaggerAppComponent will be generated It should also include an abstract Factory class annotated with @​Component. implementation 'com.google.dagger:dagger-android:2.23.2'. Dagger 2 doesn't implement some of the component methods in Android project with custom annotation processor #524

I'm trying to add Dagger2 to my project in Android Studio. This is my dependencies. compile 'com.google.dagger:dagger:2.8' annotationProcessor  2.2. Defining dependency providers (object providers) The term dependency injection context is typically used to describe the set of objects which can be injected. In Dagger 2, classes annotated with @Module are responsible for providing objects which can be injected.

Can not resolve symbol for dagger component in android. I'm trying to add Dagger2 to my project in Android Studio. This is my dependencies. compile  It cannot inject private fields. If you want to use field injection you have to define a method in your @Component annotated interface which takes the instance of the class into which you want to inject the member variable. Now let’s move to the Part 2 of this article and experience Dagger in action. For Part 2 please follow this link.

Back in the day, about 2.5 years ago when Dagger2 came out, I was excited Dagger is a dependency injection framework, which makes it easier to or provision methods, we can't really get anything from the component. Improving upon the first version, and collaborating with a team of developers at Google, Dagger 2 a much faster and improved version without Reflections was introduced. Dagger 2 is a compile-time android dependency injection framework and uses the Java Specification Request (JSR) 330 and uses an annotation processor.
