๐ง Mastering Memory Leaks in Android: A Step-by-Step Guide ๐ฑ

Memory leaks occur when your app retains resources that it no longer needs, occupying precious memory space. Understand it as leaving unused items in a room, taking up space you could use for something more valuable.
๐ก "Failure to releaseย unused objects from theย memory means that there are unused objects in the application that the GC cannot clear from memory."

Garbage collection in Android is an automatic memory management process that identifies and reclaims memory occupied by objects that are no longer reachable or in use by the application, helping to prevent memory leaks and ensure efficient memory utilization.

Stay away from static views that never get cleared from memory, causing potential leaks.

Never use context as static, as this can lead to unintended retention of resources.

Unregister listeners in onPause, onStop, or onDestroy to avoid keeping the activity alive and waiting.

When using inner classes, make them static to prevent retaining the outer class implicitly.

Be cautious when using collections that store views, especially WeakHashMap which stores hard references.

Avoid holding references to UI-specific views(TextViews/Edittext/ImageView) in background tasks, as this can lead to memory leaks.
