Memory Monitor

When you hear the term memory management in an Android app, it is basically the Random Access Memory (RAM). Managing the RAM is the most critical section in the Android app development process, as the physical memory is often constrained. The fundamental principle of memory management is to avoid a memory leak from your app.

In Android Studio there is a tool we can use to check the memory usage in the App. To check this you could follow these steps:
