Okay lets drive some people really freaking nuts including Motorola. The Android Hacker Quiz:
1. True or False. To get accurate profile data from the emulator or ADP you must run it in debug mode. Answer: False, under debug the emulator and or device runs a slower verifier. Thus, to get profile data you change a certain file to lengthen the number of times the traces.txt file is rolled over(default is 4 and that is not enough as logcat is written to screen or file in 64k chunks) and change stdio to output to the traces.txt file to get full logcat in those files. Reboot the device and grab those sets of traces.txt files.
2 The Dalvik verfier an be toggled on the emulator and the chocies are fast, portable, and debug. When testing for a new device that you do not have which verifier is more accurate or closer to actual device performance? Answer: Portable as the fast Dalvik verifier is optimized for current hardware not the future device you are attempting to get profiling data. While choosing the portable verifier will result in worse performance numbers when compared to fast it will be closer to the actual device until you have more accurate performance data.
