Question

I have an android app that appears to be working fine – but I wish to ensure that I have not just been getting away with problems like memory leaks, thread lockups etc. Is there some utility, or mode within eclipse, that will highlight potential problems that may occur in the future.

Answer 1

• StrictMode is a way of guarding against accidental disk or network access on the main thread.
• Android Lint is a recent addition to the SDK tools, to catch potential bugs and usability issues.
• FindBugs is another non-Android-specific static analysis tool.
• Android 4.0 (ICS) devices have several development options (in the Settings menu) you can enable to catch potential problems:
  • Don’t keep activities forces activities to be destroyed on exit
  • Show screen updates so you can tell if you’re doing too much rendering
  • …and more
• Traceview can tell you what your threads are doing.
