- When working on a project, close all unrelated projects.
- If things get a little screwy, try closing everything and restarting Eclipse.
- If things get a little screwy, use the menu option Project/Clean and see if that helps.
- An error in an xml resource will prevent the app from running, and Eclipse may not flag it as an error. Be very careful!
- Put the cursor on a field or function and use Ctrl+Shift+G to search for all references. This is very useful!
- Put the cursor on a function and press F3 to go to that function directly.
- Be very careful in moving projects from workspace to workspace. Back up everything first!
- Don't be afraid to reinstall Eclipse in Windows -- it's just copying files, not a full windows installation. Just back up your workspace and import your projects afterwards.
- When there appear to be lots of errors (red underlines) under code that is totally correct, try copying the code, deleting it, and pasting right back where it was. That may clear it up.
