To persist the step count across device reboots, you can use shared preferences to store the total step count.
Here is an example of how you can implement this:
This code will read the current total step count from shared preferences when the app starts, and then use a sensor listener to increment the total step count every time the step sensor fires an event. The updated total step count is then saved back to shared preferences.
This way, the total step count will be persisted across device reboots, and you can retrieve the current total step count from shared preferences at any time by calling getInt("TOTAL_STEPS").
I hope this helps! Let me know if you have any questions.
Here is an example of how you can implement this:
Code:
// Get an instance of shared preferences
val sharedPreferences = getSharedPreferences("STEP_COUNTER_PREFS", Context.MODE_PRIVATE)
// Get the current total step count from shared preferences
val totalSteps = sharedPreferences.getInt("TOTAL_STEPS", 0)
// Register the step counter sensor listener
sensorManager.registerListener(object : SensorEventListener {
override fun onAccuracyChanged(sensor: Sensor?, accuracy: Int) {}
override fun onSensorChanged(event: SensorEvent?) {
// Increment the total step count by the number of steps taken
totalSteps += event?.values?.get(0)?.toInt() ?: 0
// Save the updated total step count to shared preferences
sharedPreferences.edit().putInt("TOTAL_STEPS", totalSteps).apply()
}
}, stepSensor, SensorManager.SENSOR_DELAY_UI)
