How to stop the activity recognition after the quitting the application?

Question

I am working on a user activity tracking application. I need to track the user activity even the app is background or quits.

I have started the user activity tracking and quitting the app. After some point of time I want to stop the user activity tracking. Now the app is not having any instance. I don't have any instance to stop the user activity tracking.

After I remove the app from my recent application All the static references are cleared. Everything works fine. But I don't know How to stop the user activity tracking some time after the app quits.

/**
 * Make the actual update request. This is called from onConnected().
 */
private void continueRequestActivityUpdates() {
    /*
     * Request updates, using the default detection interval. The
     * PendingIntent sends updates to ActivityRecognitionIntentService
     */
    getActivityRecognitionClient().requestActivityUpdates(
            Constants.DETECTION_INTERVAL_MILLISECONDS,
            createRequestPendingIntent());

}

I want to know how to stop this when I was in background. Because once the app quits I don't have any instance to stop it.

Please help me on this. Thanks in advance.

To stop activity recognition updates, use the same pattern you used to request updates, but call removeActivityUpdates() instead of requestActivityUpdates(). Took this from here: link

Implement this method in the same class and call this whenever you want to remove updates:

private void removeActivityUpdates() {
    mActivityRecognitionClient = new ActivityRecognitionClient(mContext, this, this);

    Intent intent = new Intent(mContext, ActivityRecognitionIntentService.class);

    mActivityRecognitionPendingIntent = PendingIntent.getService(mContext, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

    mActivityRecognitionClient.removeActivityUpdates(mActivityRecognitionPendingIntent);
}
