So while working on bug 965369 I instrumented the code in hal/gonk/GonkSensor.cpp and observed that the poppit app receives orientation sensor results every 50ms from the moment it is launched. These results seem to ultimately be translated into 'devicemotion' events for the app.
In contrast, other apps do not trigger my GonkSensor.cpp instrumentation in a repeated manner like this. Can anyone tell me what we look for to see how we enable the accelerometer sensor for an app? I thought maybe registering for 'devicemotion' would do it, but poppit does not do that immediately. It only does that the first time it needs acceleration information, which is much later during a game. I also stripped the manifest down to just the name, icon, and invocation path using app-manager. Still the poppit app spends a ton of time processing these sensor results. Can anyone point me in the right direction? Thanks!
