Regarding Trace files generation

[sandhya]

Hi ,

I was able to generate trace files using apitrace code  on emulator using
the below steps:

PROCNAME=com.kiloo.subwaysurf
adb root
adb shell setprop wrap.$PROCNAME LD_PRELOAD=/data/egltrace.so
adb shell setprop debug.apitrace.procname $PROCNAME
adb shell am start -n com.kiloo.subwaysurf/.RRAndroidPluginActivity



But i was unable to generate trace files for running application on android
phone .Are the steps same for this? My phone is non rooted phone and /data
doesnot have permissions .Can  any one suggest me how to proceed.(adb shell
setprop wrap.$PROCNAME LD_PRELOAD=/data/egltrace.so   is not working
properly,when i use getprop iam getting null value)
