      • 3. Use adb logcat, and write the result to a file -> Might increase the overhead
      • 4. Use PR_LOG, but open log file per process -> Somehow fail to open the log file with "Homescreen" process.
    • Coordinate with Gina and alive about the log format.

  • JPEG encoder/decoder. /CTai
  • Study JPEG encoder/decoder theory. /CTai
  • Understand what is NEON /CTai
  • study Android RenderScript / JW
