I am changing my android mobile app to support both tablets and mobile phone. For this I am changing my activity class into fragment. In my activity class I have an instance of my application class created as below:
appCtx = (UnityMobileApp) getApplication();
Where UnityMobileApp is my Application class.
Now I want to create the same instance in my fragment class. Can you guys please help me solve this?
The method getActivity() may have possibility to return null. This may crash your app.So it is safe to use that method inside the onActivityCreated(). Eg:
private UnityMobileApp appCtx;
.
.
...
@Override
public View onCreateView(...){
...
}
@Override public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
appCtx = ((UnityMobileApp) getActivity().getApplication());
}
...
//access the application class methods using the object appCtx....

If someone is looking for a Kotlin version. This works for me:
(activity?.application as YourApplicationClass)
Alternatively using Kotlin
fun bar() {
(activity?.application as UnityMobileApp).let {
it.drink()
} ?: run {
Log.d("DEBUG", "(╯°□°）╯︵ ┻━┻")
}
}
