Memory Leaks

Setup Leak Canary

• https://github.com/square/leakcanary
• Add to gradle. initialize on app startup, ensure debug is off

Context Leaks via Threads

• When not static will retain reference to outer class beyond lifecycle of container (Activity, Fragment). In below example MyTask will retain a reference to Activity
