+### Android ###
+
+The following instructions should work at least for Android Ice Scream
+Sandwitch:
+
+For standalone applications the instructions above for Linux should
+work. To trace applications started from within the Android VM process
+(app_process aka zygote) you'll have to wrap this process and enable
+tracing dynamically for the application to be traced.
+
+- Wrapping the android main VM process:
+
+ In the Android root /init.rc add the LD_PRELOAD setting to zygote's
+ environment in the 'service zygote' section:
+
+ """
+ service zygote ...
+ setenv LD_PRELOAD /data/egltrace.so
+ ...
+ """
+
+ Note that ICS will overwrite the /init.rc during each boot with the
+ version in the recovery image. So you'll have to change the file in
+ your ICS source tree, rebuild and reflash the device.
+ Rebuilding/reflashing only the recovery image should be sufficient.
+
+
+- Copy egltrace.so to /data
+
+ On the host:
+ $ adb push /path/to/apitrace/build/wrappers/egltrace.so /data
+
+
+- Adjust file permissions to store the trace file:
+
+ By default egltrace.so will store the trace in
+ /data/app_process.trace. For this to work for applications running
+ with a uid other than 0, you have to allow writes to the /data
+ directory on the device:
+
+ # chmod 0777 /data
+
+
+- Enable tracing for a specific process name:
+
+ To trace for example the Settings application:
+ # setprop debug.apitrace.procname com.android.settings
+
+ In general this name will match what 'ps' reports.
+
+
+- Start the application:
+
+ If the application was already running, for example due to ICS's way
+ of pre-starting the apps, you might have to kill the application
+ first:
+
+ # kill <pid of app>
+
+ Launch the application for example from the application menu.
+
### Mac OS X ###
Run the application you want to trace as
