App Memory Consumption

Question

I have been playing with optimizing my app, and I see that there are some general ideas on how much memory it should use... I'm running between 70-80Mb right now, is that a crazy number or just a little on the heavy side?

My second question is about the memory I am using. About 42Mb is taken up by graphics, whether I run the app with the layout graphics or run it without setting any views... any ideas on where to look? I feel like it is the theme, but I am not sure how to test that.

I've been searching for days to figure out why it uses so much and cannot figure it out. It remains constant regardless of which activity I am on, any ideas are welcome!

UPDATE:

• I ended up running it on an emulator and got about 26Mb, more what I was expecting, but it runs at 70Mb with the 42Mb of graphics on the actual device.
• The emulator allows for a 384Mb app after getting memoryclass information, while the device only allows 256Mb... the emulator has more storage and runs more efficiently.
• The emulator is Android 8.1 27api while the device is Android 7.0 24api.
• Tried on an older Android 5.1.1 api 22 below also.

Any ideas?

I have another question with about why the emulators have a such a difference in performance here if you know the answer on that, but I wanted to keep these questions separate: Other Question

Answer 1

You can use LeakCanary A memory leak detection library for Android and Java. Maintain by Square. This is one of the best developer's Tool for memory optimization and detecting leaks.here

Answer 2

Android Studio has an awesome tool called Memory Profiler. It helps you analyze possible memory leaks and see which calls are using up the most memory. You can even pause the processor and 'zoom in' to deep dive on the call stack.
