How do I discover memory usage of my application in Android?

Question

How can I find the memory used on my Android application, programmatically?

I hope there is a way to do it. Plus, how do I get the free memory of the phone too?

Answer 1

Android Studio 0.8.10+ has introduced an incredibly useful tool called Memory Monitor.

What it's good for:

• Showing available and used memory in a graph, and garbage collection events over time.
• Quickly testing whether app slowness might be related to excessive garbage collection events.
• Quickly testing whether app crashes may be related to running out of memory.

You can have plenty good information on your app's RAM real-time consumption by using it.
