I want to save the time as "dateString" when the gyro reading x = 0.0, y = 0.0, z = 0.0 and when x> 0.0 && & y> 0.0 && z> 0.0 save the time as "dateString1". I can’t time if the condition is met, because it takes the current time of my phone. It constantly works, so it is not possible to get the time when an event occurs, what is the solution for the same?
Example. If my phone is at rest, the gyro sensor will provide x = 0.0, y = 0.0, z = 0.0 if reading remains the same for three hours. Suppose this is the time that sleep begins. when the reading suddenly changes in terms of x, y, z, it will be the time of awakening.
( )?
x, y, z, 0,0,0,0,0,0 .
pic up x, y, z . , .
