android-discuss, using TraceView

 

using TraceView

 Hi,
I have recently started working on an app which has both Java and
native components. I am trying to generate trace information for both
components using Debug.startMethodTracing("myapp") and
Debug.startNativeTracing() alternately. However, both are behaving
unexpectedly. When I use Debug.startMethodTracing("myapp"), I can see
a file "/sdcard/myapp.trace" being created but it is always empty no
matter how long I run my app. When I use Debug.startNativeTracing()
and start the emulator with the -trace <tracename> switch, I see a
message saying "Trace started", but when I try to run my app, the
emulator crashes. Am I missing something obvious here? How do I debug
this problem?

Thanks for any help.

1. Noob Question

I am following the directions to create the Hello, Android application
shown in the tutorial (http://developer.android.com/guide/tutorials/
hello-world.html), but instead of the expected Hello, Android text
appearing, all I see are, first of all, the letters A N D R O I D
onscreen for a few seconds, followed by a logo-like ANDROID word next
to an iimage (of a stylized android).  Anyone know what I am doing
wrong?  Everything I've done seems exactly according to directions. Of
course, I probably screwed up somewhere, but I'll be darned if I can
see where.
