What happens if you do not call `super.onCreate(savedInstanceState)` in an Activity?

When you do not call super.onCreate(savedInstanceState) in an Activity, the inherited behaviors from the superclass (which is typically AppCompatActivity or Activity) will not be executed. This is significant because the onCreate method in the superclass contains essential initialization that sets up the Activity's state and environment.

By skipping this call, you essentially bypass all the foundational work that the superclass does, such as creating the window, setting up the content view, handling configuration changes, and initializing various components and system services that are necessary for the Activity to function correctly. This can lead to unpredictable behavior or issues within your Activity, as the framework expects that the lifecycle and set-up processes are followed correctly.

The other options suggest more severe consequences, such as crashing the application or preventing variable initialization, but the primary issue lies in not adhering to the expected lifecycle management protocol defined by the Android framework, leading to incomplete Activity setup.
