Android – how to get time if some conditions encounter gyroscope reading

Invalid Sign

Example – if my phone is stationary, the gyro sensor will provide x = 0.0, y = 0.0, z = 0.0. If the reading is still the same within three hours. Suppose this is the start time of phone sleep. When the reading will suddenly change in X, y, Z, it will be the wake-up time

How do I detect this (sleep start time and wake-up time)?

The following code is to detect the gyro readings x, y and Z, which still display 0.0, 0.0 and 0.0 respectively

When the telephone values of PIC, x, y, Z increase, how can we add code to detect time, as described above

Note: please do not tell me that timestamp is the solution I have tried

resolvent:

In the sensoreventlistener, you can use the callback parameter sensorevent event to obtain the timestamp using the following code,

long timeStamp = event.timestamp;

Note: event.timestamp will return long

Edit: update the answers based on your comments

To check if the device has moved for more than three hours, use the following code

Initialize long lasttimestamp = 0; In the global variable of your class

SensorEventListener sensorEventListener = new SensorEventListener() {
            @Override
            public void onSensorChanged(SensorEvent event) {
                float x = event.values[0];
                float y = event.values[1];
                float z = event.values[2];
                if(Math.round(x) == 0 && Math.round(y) == 0 && Math.round(z) == 0) {
                    //device didn't move - store current timestamp
                    lastTimeStamp = event.timestamp;
                } else {
                    //below if condition is to check if device hasn't been idle 
                    if (lastTimeStamp == 0) {
                        return;
                    }

                    //(3 * 60 * 60 * 1000) checks if device wasn't moved for more than 3 hours
                    if ((event.timestamp - lastTimeStamp) > (3 * 60 * 60 * 1000)) {
                        //code goes here 
                    }
                    lastTimeStamp = 0;
                }
            }

            @Override
            public void onAccuracyChanged(Sensor sensor, int accuracy) {

            }
        };

I hope this will be clearer
