Answer 1

1) you can use LeakCanry for optimize memory. leakCanry will give you report for each individual leaks or when multiple instance of an activity will be on stack.

here is more info and integration guide https://github.com/square/leakcanary

2) you can check android studio memory monitor for your app's memory use. from that graph you can check when GC is being called and which activity or function is taking more memory so you can optimize through it.

3) i have gone through udacity tutorial and videos. you can see how to improving rendering for your layouts

• Need to reduce unnecessary views.
• dont apply unnecessary background.

4) one more important thing use ApplicationContext where you can use it because Activity context keeps in stack and wont be eligible for GC until that context related task is being finished.
