Getting Android Traceview to work

When I try to run traceview I get:

'java' is not recognized as an internal or external command, operable program or batch file. SWT folder '' does not exist. Please set ANDROID_SWT to point to the folder containing swt.jar for your platfo rm.

I can't figure out how i开发者_如何转开发t get it working. Does anyone know?

If you're running under Windows, before calling traceview first run traceview.bat (in /tools) to set some environment variables, among other things.

Also, you need to call it with an absolute path to your trace file. At least in my environment, a relative path gives me an error.

I write my trace files to the emulator's SD card, then when I want to examine them first copy them to my machine:

adb pull /sdcard/app.trace /app/traces
traceview.bat c:/path/app/traces/app.trace
