Android : References to a Context and memory leaks

by

This is fine, and will not cause a memory leak.

As soon as onCreate finishes executing, h will be out of scope and become eligible for garbage collection. If h was static, then you would run into problems. Only when the reference to the context outlives the lifecycle of the context itself will a memory leak occur. A few helpful hints:

  • Use Context.getApplicationContext() when possible. This context will live as long as your application is alive.
  • Be careful when using static fields and inner classes.
  • Run your application through a profiler to check for leaks.
