# Why

Detecting memory leaks on android is very hard. We should monitor our app and modules to prevent them.

# How

[Leak Canary](https://square.github.io/leakcanary/) is a memory leak detection tool for android, which constantly monitoring the app for leaks. When the leak is detected, the tool dumps and analyzes the heap, then categorizes leaks and provides a simple summary.
