What reasons could lead to the garbage collector not removing the context stored in the application?

Garbage collector in Android will not delete a context stored in an application if there are still strong references to it. Main reasons:

• Memory leaks caused by static variables. If the context is stored in a static variable, it will live until the process ends.
• Long-lived references from other objects. For example, if the context is passed to an object with a long lifecycle (like a singleton), the collector cannot delete it.
• Internal reference cycles. Although Java GC can handle cycles, if the context is linked to objects that are actively used themselves, it will not be removed.
• Using Activity context instead of Application. Activity context lives only while the activity is active, but if stored in long-lived objects, it can lead to leaks.
