Method injection dagger2 null exception when asking for the dependency












0














Hi i'm trying to use method injection with dagger 2 and im getting null pointer exception when using the injected dependency i tried removing the @provide annotation and extracted the DialogManger in separate module here



@Module


public class DialogManagerModule {



Context context;

public DialogManagerModule(Context context){
this.context = context;
}

@Provides
DialogManager provideDialogManager(Context context){
return new DialogManager(context);
}

@Provides
ProgressDialogInteractor provideProgressDialogInteractor(){
return new ProgressDialog();
}

@Provides
Context provideContext(){
return context;
}


}



public class DialogManager {

Context context;

ProgressDialogInteractor progressDialog;

@Inject
public void setProgressDialog(ProgressDialogInteractor progressDialog) {
this.progressDialog = progressDialog;
}

public DialogManager(Context context) {
this.context = context;
}

public void showDatePickerDialog(DatePickerDialog.OnDateSetListener listener){
Calendar calendar = Calendar.getInstance();
new DatePickerDialog(
context
, listener
, calendar.get(Calendar.YEAR)
, calendar.get(Calendar.MONTH)
, calendar.get(Calendar.DAY_OF_MONTH))
.show();
}

public void showProgressDialog(@Nullable String progressText){

progressDialog
/* .setText(progressText)
.showText()*/
.show();

}


}



and here how i called the component



component =((App) getActivity().getApplication()).getComponent()
.newPersonalInfoFragmentComponent(new PersonalInfoFragmentModule(this), new DialogManagerModule(getContext()));

          You should provide your context like that in ContextModule class, and you have to provide all objects that you use in provide methods.



          @Singleton
          @Module
          public abstract class ContextModule {

          @Binds
          abstract Context provideContext(Application application);
          }
