To make High Performance Android Apps by Mr. Tim Bray
- Don't use I/O or networking task in UI thread.
- 25ms loss even if you issue I/O task for 1 byte
- Ping on 3G takes 108, 350, 500, 800ms
- Show a progress dialog when a process takes longer than 200ms
- If it's not fast enough, don't guess. Measure and find out why.
- Indexing makes reading fast but writing slow (SQLite)
- Use text for loging
