Make sure you have these added as gradle dependencies :-
implementation "android.arch.lifecycle:livedata:1.1.1"
implementation "android.arch.lifecycle:viewmodel:1.1.1"
implementation "android.arch.lifecycle:extensions:1.1.1"
And also make sure to add google() to your repositories in project level gradle and you are connected to internet !!
Edit
For androidx use :-
def lifecycle_version = "2.0.0"
// ViewModel and LiveData
implementation "androidx.lifecycle:lifecycle-extensions:$lifecycle_version"
Add these two lines in gradle.properties
android.useAndroidX=true
android.enableJetifier=true
when you add these two lines you will get an error in activity.
You need to modify all components from android to androidX
Eg: android.support.v7.app.AppCompatActivity to androidx.appcompat.app.AppCompatActivity

I have added #Database(entities = {Class_.class}, version = 1) in AppDatabase.java . The #Database annotation for your database class, and #Entity for your entity. I have given as correct. Then the issue solved.
I faced the same problem even after adding correct dependency in my
build.gradle of my app module. My problem was ,I have used different module for separating database layer and I have moved my dependency to build.gradle of corresponding module solved my problem.
Hope this will helpful to someone else !!!
#Database annotation is missing
add annotation something like this
#Database(entities = [Articles::class], version = 1)
abstract class NewsDatabase : RoomDatabase() {
abstract fun articlesDao(): ArticlesDao
}
also for kotlin add following line to dependencies
kapt "android.arch.persistence.room:compiler:1.1.1"
also i was using kotlin and all my data class members were non nullable.
worked fine after i changed them to nullable types

Add below line to application tag in AndroidManifest.xml if you don't have any class which extends Application class
android:name="android.support.multidex.MultiDexApplication"
or add below to onCreate() method if you have any class which extends Application class
MultiDex.install(getBaseContext());
Create an Application Class
Initialize it MultiDex in onCreate()
public class MyApplication extends Application {
private static MyApplication applicationContext;
public static boolean isNotificationProcessing = false;
public MyApplication() {
applicationContext = this;
}
#Override
public void onCreate() {
super.onCreate();
MultiDex.install(getBaseContext());
}
}
Rebuild and run again
I have tried a great deal debugging this issue but unable to find the cause. Dagger simply doesn't create the DaggerComponent classes. I've checked SO for duplicates but none of the solutions provided worked.

Dagger is failing to generate the component class in my Application class. I've tried clean building, I've tried invalidating cache but nothing works.
You can start a fresh project by yourself instead of following the tutorial project. If you do so, here is the solution.
These two lines are responsible to generate the compile-time framework in Dagger 2.
compile 'com.google.dagger:dagger:2.14.1'//generates framework in compile time
annotationProcessor 'com.google.dagger:dagger-compiler:2.14.1' //generates framework in compile time based on the annotations you provided.
Full setup Dagger
//dagger 2
compile 'com.google.dagger:dagger:2.14.1'
annotationProcessor 'com.google.dagger:dagger-compiler:2.14.1'
//to enable DaggerActivity, DaggerBroadcastReceiver, DaggerFragment etc classes
compile 'com.google.dagger:dagger-android:2.14.1'
annotationProcessor 'com.google.dagger:dagger-android-processor:2.14.1'
//support libraries with dagger 2
compile 'com.google.dagger:dagger-android-support:2.14.1'
Note: You need to configure Annotation Process as provided in the screenshot below. You can do this File>Other Settings>Default Settings>search"Annotation processor"

Im trying to use Dagger 2 on android. I previously had it working and i had an appModule injecting dependencies into specific classes in the app. My Issue is that iam getting the error
Error:(14, 55) error: cannot find symbol class DaggerAppComponent
which attempting to import. this is an autogenerated class
below are my Dagger specific dependencies in my build.gradle file
compile 'com.google.dagger:dagger-compiler:2.0.2'
compile 'com.google.dagger:dagger:2.0.2'
provided 'javax.annotation:jsr250-api:1.0'
Ive tried cleaning and rebuilding the app numerous times but the class wont generate. Ive also tried using
compile 'org.glassfish:javax.annotation:10.0-b28'
for my annotations but Iam having no luck still? If anyone can help me out id appreciate. Its kind of difficult to see exactly what is going on for me at present? Thanks
EDIT: Component code
this was working before and i just added 1 extra class to inject into?
#Singleton
#Component(modules = AppModule.class)
public interface AppComponent {
void inject(RegHelper reghelper);
void inject(headerFooterRecViewAdapter headadapter);
void inject(SectionListExampleActivity seclistactivity);
}
This did the trick for me with the (current) latest dagger dependecies.
`dependencies{
...
compile 'com.google.dagger:dagger:2.11'
compile 'com.google.dagger:dagger-android-support:2.11'
annotationProcessor "com.google.dagger:dagger-compiler:2.11"
}`
Please add
apt 'com.google.dagger:dagger-compiler:2.x'
to your app build.gradle file

You need to install this plugin https://bitbucket.org/hvisser/android-apt in order for Android Studio to see the Dagger Components.
I was having a similar issue with Dagger 2. I had an AppComponent and an ActivityComponent (being a subcomponent). And as soon as I would add a new inject() function in the AppComponent, I would get the above errors.
There was more errors besides the 'cannot find symbol' error but they were very vague and I couldn't debug my issues. After digging and researching stackoverflow and different tutorials, I realized I was using Dagger incorrectly. Specifically the way my AppComponent and ActivityComponent was setup.
I was under the assumption that I could inject my 'Activity' or 'Fragment' with both my AppComponent and ActivityComponent. This turned out to be wrong, at least I found out that it wasn't the right way of using Dagger.
My Solution:
AppComponent
#Singleton
#Component(modules = {AppModule.class})
public interface AppComponent {
void inject(MyApp application);
void inject(ContextHelper contextHelper);
// for exports
MyApp application();
PrefsHelper prefsHelper();
}
App Module
#Module
public class AppModule {
private final MyApp application;
public AppModule(MyApp application) {
this.application = application;
}
#Provides #Singleton
public MyApp application() {
return this.application;
}
#Provides #Singleton
public PrefsHelper providePrefsHelper() {
PrefsHelper prefsHelper = new PrefsHelper(application);
return prefsHelper;
}
}
ActivityComponent
#ActivityScope
#Component (dependencies = {AppComponent.class}, modules = {ActivityModule.class})
public interface ActivityComponent {
void inject(MainActivity activity);
void inject(OtherActivity activity);
void inject(SomeFragment fragment);
}
ActivityModule
#Module
public class ActivityModule {
private final MyActivity activity;
public ActivityModule(MyActivity activity) {
this.activity = activity;
}
#Provides #ActivityScope
public ContextHelper provideContextHelper(MyApp application) {
// My ContextHelper depends on certain things from AppModule
// So I call appComponent.inject(contextHelper)
AppComponent appComponent = application.getAppComponent();
ContextHelper contextHelper = new ContextHelper(activity);
appComponent.inject(contextHelper);
return contextHelper;
}
}
Application
public class MyApp extends Application {
private AppComponent appComponent;
#Override
public void onCreate() {
super.onCreate();
initializeDepInj();
}
private void initializeDepInj() {
appComponent = DaggerAppComponent.builder()
.appModule(new AppModule(this))
.build();
appComponent.inject(this);
}
public LockAppComponent getAppComponent() {
return appComponent;
}
}
Activity
public class MainActivity extends AppCompatActivity {
// I get it from ActivityModule
#Inject
ContextHelper contextHelper;
// I get it from AppModule
#Inject
PrefsHelper prefsHelper;
ActivityComponent component;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setupInjection();
}
protected void setupInjection() {
MyApp application = (MyApp) getApplication();
component = DaggerActivityComponent.builder()
.appComponent(application.getAppComponent())
.activityModule(new ActivityModule(this))
.build();
component.inject(this);
// I was also doing the following snippet
// but it's not the correct way since the ActivityComponent depends
// on AppComponent and therefore ActivityComponent is the only
// component that I should inject() with and I'll still get classes
// that are provided by the AppComponent/AppModule
// application.getAppComponent().inject(this); // this is unneccessary
}
public ContextHelper getContextHelper() {
return contextHelper;
}
}
I don't know if it directly resolves your issue but it should at least shed some light on how to use Dagger properly.
Hope it helps.
I had the same problem on my setup, Android Studio 2.2 within the following application class:
public class NetApp extends Application {
private NetComponent mNetComponent;
#Override
public void onCreate() {
super.onCreate();
// Dagger%COMPONENT_NAME%
mNetComponent = DaggerNetComponent.builder()
// list of modules that are part of this component need to be created here too
.appModule(new AppModule(this)) // This also corresponds to the name of your module: %component_name%Module
.netModule(new NetModule("https://api.github.com"))
.build();
// If a Dagger 2 component does not have any constructor arguments for any of its modules,
// then we can use .create() as a shortcut instead:
// mNetComponent = com.codepath.dagger.components.DaggerNetComponent.create();
}
public NetComponent getNetComponent() {
return mNetComponent;
}
}
I'm using the following gradle declaration for dagger 2:
//Dagger 2
// apt command comes from the android-apt plugin
apt 'com.google.dagger:dagger-compiler:2.7'
compile 'com.google.dagger:dagger:2.7'
provided 'javax.annotation:jsr250-api:1.0'
I could solve the problem by rebuilding the complete project (with errors) and then adding the import of the DaggerNetComponent that was missing before.
Just add #Module to Api class & rebuild the project.
Hope you all doing well.
I was facing the same problem and spent a lot of time over stack overflow. At last I go through this and able to find solution. Briefly, You have to make some changes in your module level Gradle file. Please remove
apply plugin: 'com.neenbedankt.android-apt'
at the top of the file. And replace
apt 'com.google.dagger:dagger-compiler:2.11'
with
annotationProcessor 'com.google.dagger:dagger-compiler:2.11'
After that rebuild your project and you will be able to import your Dagger prefix classes. Hopw it will help you out.
