Android Emulator Showing Empty Screen?

I am developing a news app previously it was showing JSON response but now showing the empty white screen below fragment class where I have implemented dagger 2 and retrofit' publi

Solution 1:

Regarding Dagger setup, this line of cast does not seem correct:

// BBCSportFragment.onCreate > Callback.onResponse
(BBCSportFragmentComponent) DaggerApplicationComponent.builder().contextModule(newContextModule(getContext())).build();

A correct setup should not require you to cast the result of .build().

If BBCSportFragmentComponent is using component dependency (with an annotation like @Component(dependencies = ApplicationComponent.class)), maybe you mean this:

bbcSportFragmentComponent =
    DaggerBBCSportFragmentComponent.builder()
        .applicationComponent(applicationComponent)
        .contextModule(newContextModule(getContext()))
        .build();
bbcSportFragmentComponent.injectBBCSportFragment(BBCSportFragment.this);

Then, the fields that Dagger should inject should be annotated @Inject. Otherwise bbcSportFragmentComponent.injectBBCSportFragment will run successfully doing nothing.

Then, Dagger documentation suggests injecting a Fragment inside onAttach before super.onAttach().
