UninitializedPropertyAccessException: lateinit property pref has not been initialized

I know a similar question has been answered [Here](

). But that was due to butter knife library problem but my case is different. In my case when I use dagger injected properties in my base activity it shows me error **Caused by: kotlin.UninitializedPropertyAccessException: lateinit property pref has not been initialized**

But the same property when I use in my sub activity (Login activity) it works fine.

eg. **pref.setLanguage("abc") -> it works fine in login activity but throws error in base activity**

Here is my code:

**BaseActivity**

```kotlin
abstract class BaseActivity : AppCompatActivity() {
@Inject
lateinit var pref: AppSharedPreferences
@Inject
lateinit var utils: Utils
lateinit var mCurrentLanguage: String
protected lateinit var progressBarUtils: ProgressBarUtils

override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
progressBarUtils = ProgressBarUtils(this)
mCurrentLanguage = "EN"
pref.setSelectedLanguage(mCurrentLanguage)
}
}
```

**LoginActivity**

```kotlin
class LoginActivity : BaseActivity() {
private val TAG = this.javaClass.name
lateinit var loginViewModel: LoginViewModel
@Inject
lateinit var viewModelFactory: LoginViewModelFactory


override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_login)
AndroidInjection.inject(this)
loginViewModel = ViewModelProviders.of(this, viewModelFactory).get(
LoginViewModel::class.java)
loadData("abc", "xyz")
observerOnLoginResult()
observerOnLoginError()
}


private fun observerOnLoginError() {
loginViewModel.loginError().observe(this, Observer<String> {
progressBarUtils.cancelProgressDialog()
if (it != null) {
Toast.makeText(this, resources.getString(R.string.error_message) + it,
Toast.LENGTH_SHORT).show()
}
})
}

private fun observerOnLoginResult() {
loginViewModel.loginResult().observe(this,
Observer<LoginModel> {
progressBarUtils.cancelProgressDialog()
if (it != null) {
setData(it)
}
})
}

private fun setData(loginData: LoginModel) {
pref.setCurrentUserName(loginData.data.userName)
}

private fun loadData(email: String, password: String) {
progressBarUtils.showProgressDialog()
val builder = StringBuilder()
var auth = Base64.encodeToString(("$email:$password").toByteArray(), Base64.NO_WRAP)
builder.append("Basic ")
builder.append(auth)
loginViewModel.getLoginData(builder.toString())
}

override fun onDestroy() {
loginViewModel.disposeElements()
super.onDestroy()
}
```

**AppModule**

```kotlin
@Module class AppModule(val app: Application) {

@Provides
@Singleton
fun provideApplication(): Application = app


@Provides
@Singleton
fun provideSharedPreferences(): AppSharedPreferences = AppSharedPreferences(app)


@Provides
@Singleton
fun provideUtils(): Utils = Utils(app)
}
```

**Builder Module**

```kotlin
@Module abstract class BuildersModule {

@PerActivity
@ContributesAndroidInjector(modules = arrayOf(LoginModule::class))
abstract fun contributeLoginActivity(): LoginActivity

@PerActivity
abstract fun contributeBaseActivityActivity(): BaseActivity
}
```

**AppComponent**

```kotlin
@Singleton @Component(
modules = arrayOf(AndroidInjectionModule::class, AppModule::class, BuildersModule::class))

interface AppComponent {
fun inject(app: LotusApp)
}

```

You can't use an object before you initialize it.

override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState) // prefs called in parents onCreate!
setContentView(R.layout.activity_login)
AndroidInjection.inject(this) // injection happens here

Get your calls in order. Easiest way to fix would be to move `AndroidInjection.inject(this)` before the call to `super.onCreate(...)`.
