What context should be chosen when developing a library?

When developing a library for Android, it is recommended to use a context that does not lead to memory leaks. Usually, this is the application context (ApplicationContext), not the activity context (Activity).

The reason is that the activity context is tied to the UI lifecycle and can be destroyed, whereas the application context lives longer and is safe to store in singletons and libraries.

Example of obtaining the application context:

Context appContext = context.getApplicationContext();

Using appContext in a library helps avoid memory leak issues and improper lifecycle management of components.
