MySQL Function to Determine Zip Code Proximity / Range

由 ∥☆過路亽．° 提交于 2019-12-07 10:13:23
问题 I have been able to create php function to determine a list of zip codes within a certain range of a given zip code. However, my next task is a bit more complex. Lets say the table has the following columns: id, username info latitude longitude range Each record has a unique row id, some information, a latitude, a longitude, and a maximum range from those coordinates that the person wants this entry to be found for. So, if I create an entry with the coordinates -20, 50 with a range of 15,

由 假如想象 提交于 2019-12-06 16:55:37
I coded an app based on proximity sensor , but I would like to be able to give users the ability to change the sensitivity of the sensor. Is it possible? If yes how to do it? Just "implements SensorEventListener" and follow the code : public void onCallStateChanged(int state, String incomingNumber) { switch (state) { case TelephonyManager.CALL_STATE_IDLE: System.out.println("My Call IDLE"); CallState = false; StartAudioSpeacker(); System.out.println("Is phone speaker : "+ audioManager.isSpeakerphoneOn()); if (audioManager.isSpeakerphoneOn()) { audioManager.setSpeakerphoneOn(false);

I have configured proximeter successfully in my code. Now I want to turn off & on screen programmatically.

How best to perform corridor range search over a set of latitude / longitude coordinates

由 这一生的挚爱 提交于 2019-12-06 06:39:33
问题 What would be the best approach to finding the set of coordinates, from say about 5,00, which lie within a path of points, given a specified width. eg an aircraft following several waypoints. Is there a good way to also sort them in the same order as the route. Calculation speed would be more important than accuracy, since I'm looking at producing a list of suggestions. From what I've looked at, I presume it's not straightforward, and the question is a bit broad, but any suggestions/pointers

Proximity sensor in Swift (from Objective-C)

由 故事扮演 提交于 2019-12-06 03:58:07
问题 I'm a relatively new user to swift and now, I need to take advantage of the proximity sensor of an iPhone. I don't matter the distance, but I want to know when something is near the iPhone. So I found this code in Objective-C that worked, but I need it in Swift. I have tried some ways, but any worked. So here is the code I need: - (void) activateProximitySensor { UIDevice *device = [UIDevice currentDevice]; device.proximityMonitoringEnabled = YES; if (device.proximityMonitoringEnabled == YES)

Help with PROXIMITY_SCREEN_OFF_WAKE_LOCK in Android

由 允我心安 提交于 2019-12-06 00:30:52
问题 I've enabled the proximity wakelock in my app, and it turns off the screen when the proximity sensor detects something. But there is a problem when the screen wakes back up -- it goes to the lockscreen, not my app. This happens regardless of the time that the screen was off (even if the sensor is cleared after a few seconds). Here's the code I used: int PROXIMITY_SCREEN_OFF_WAKE_LOCK = 32; mProximityWakeLock = pm.newWakeLock(PROXIMITY_SCREEN_OFF_WAKE_LOCK, LOG_TAG); if(!mProximityWakeLock

Alert when two users/friends are near to each other - Android Proximity

I tried searching but i couldn't find anything. My Question is " How can i alert 2 or more users if they are nearby each other? " in android using Geo-fencing or something else. Say, If a UserA is in football ground and UserB walking nearby that football ground. Then UserA and UserB automatically gets notification that UserA/UserB are somewhere nearby. Rafique Mohammed Finally after spending a couple of hours thinking, I thought a better way to do this: Setup a database (MySQL,SQL etc) in your server which have users table and location table which have the locations data In Android create a
