"RuntimeError: Wrong Nr of events" executing the app-launch-profiler

[Sergio Cazzolato]

I am getting errors when running the lttng profiler for the apps: Calculator, music, Camera, Clock, Here, Gallery , Ebay

See the commands executed and the result here: http://paste.ubuntu.com/16053036/
I also tested with different parametes and always got the same error (sometimes it works)

To get the process to use, run ubuntu-app-triplet with the following names for each app.

calculator: com.ubuntu.calculator
music: com.ubuntu.music
camera: com.ubuntu.camera
clock: com.ubuntu.clock
here: com.nokia.heremaps
gallery: com.ubuntu.gallery
ebay: com.ubuntu.developer.webapps.webapp-ebay

For the following apps, the results are ok: Messaging, Web Browser, System Settings, Dialer, Address Book

The blind guess is that the sleep time is too short.

The tool works in a way that it starts the app and expects the first frame event. After the defined sleep time the app gets stoped. This error happens when the first frame is not drawn before the app gets closed. Try to use longer sleep. Like 10secs

I have used longer times (12s), I am gonna try with even longer ones to see if it is the solution.

Tried with 12 and 15 seconds and I got the same error.

These are the event I got when I executed the here app with command
profile_appstart.sh -u 127.0.0.1 -p 0000 -a com.nokia.heremaps_here_1.0.9 -c 10 -s 15

It is clear that the qtmir:firstFrameDrawn event is arriving twice. This app is the only one it is being executed in the device.
