DDMS를 통해 heap 과 Thread 확인시 문제

thread updates not enabled for selected client

이걸 함 보고 싶었는데...걍 안나와 버려서 방법찾았다.

For posterity, I found the answer.   I didn't find any button which 
was referenced by the error message above, but I was able to locate 
under Windows->Preferences->Android->DDMS to check the 'Thread Updates 
Enabled by Default' and then thread data was available (after 
restarting the emulator).
