Best practice: Minimizing memory use

To minimize runtime memory, consider the following guidelines:

  • Use primitive types (such as int or Boolean) instead of objects (such as String or Integer).
  • Do not depend entirely on the garbage collector.
  • Avoid creating many objects quickly.
  • Set object references to null when you are finished using them.
  • Reuse objects as much as possible.
  • Move heavy processing to the server. For example, you can filter or sort data before sending it to the BlackBerry® device.
