Android Question Orientation and accelerometer

[luke2012]

Hi all,
Starting from @Erel Tutorial (https://goo.gl/h9XuDD) is it possible to:

1) Recording the data (h24 log) about Orientation and accelerometer sensors?
2) Recognize (intercept) if the phone is dropped ?
3) Implement this also within iOS App ?

Thanks in advance for your reply.

1) of course, using the correct PhoneWakeState and a SQLite database
2) of course, calculating the G and checking if it is between 0 (free fall) and a higher value (limit you choose) : G = Sqrt(x*x + y*y + z*z)
3) nope as far I know

 

[AlpVir]

G = Sqrt(x*x + y*y + z*z)

I do not think the formula is correct or it does not return the value of g we all know (9.81 cm/sec^2).

You need to have a foreground service.

You can monitor the orientation and accelerometer with B4i, however it is only possible to monitor the sensors when your app is in the foreground.

Thanks @Erel for your useful reply. What you mean exactly with "foreground server" ?

I don't know this one: g = 9.81 cm/sec^2 !
I only know this one: g = 9.81 m/sec^2

Swiss accuracy (in italian "Precisione svizzera") !!!

I meant foreground service (Service.StartForeground).
