Android – Find distance between two points on map using Google Map API V2

androidgoogle-maps-api-2

I am using google map api v2 in my android application, I am able to show the map and put markers on it, but now I am stuck with the problem in which I need to find out the distance between two markers or points placed on map, I have already gone through the docs but didn't find anything helpful in this case.

If anyone knows how to solve this then please help me.

Thanks

In Google Map API V2 You have LatLng objects so you can't use distanceTo (yet).

You can then use the following code considering oldPosition and newPosition are LatLng objects :

// The computed distance is stored in results[0].
//If results has length 2 or greater, the initial bearing is stored in results[1].
//If results has length 3 or greater, the final bearing is stored in results[2].
float[] results = new float[1];
Location.distanceBetween(oldPosition.latitude, oldPosition.longitude,
                newPosition.latitude, newPosition.longitude, results);

Android – Why fragments, and when to use fragments instead of activities

#1 & #2 what are the purposes of using a fragment & what are the advantages and disadvantages of using fragments compared to using activities/views/layouts?

Fragments are Android's solution to creating reusable user interfaces. You can achieve some of the same things using activities and layouts (for example by using includes). However; fragments are wired in to the Android API, from HoneyComb, and up. Let me elaborate;

The ActionBar. If you want tabs up there to navigate your app, you quickly see that ActionBar.TabListener interface gives you a FragmentTransaction as an input argument to the onTabSelected method. You could probably ignore this, and do something else and clever, but you'd be working against the API, not with it.
The FragmentManager handles «back» for you in a very clever way. Back does not mean back to the last activity, like for regular activities. It means back to the previous fragment state.
You can use the cool ViewPager with a FragmentPagerAdapter to create swipe interfaces. The FragmentPagerAdapter code is much cleaner than a regular adapter, and it controls instantiations of the individual fragments.
Your life will be a lot easier if you use Fragments when you try to create applications for both phones and tablets. Since the fragments are so tied in with the Honeycomb+ APIs, you will want to use them on phones as well to reuse code. That's where the compatibility library comes in handy.
You even could and should use fragments for apps meant for phones only. If you have portability in mind. I use ActionBarSherlock and the compatibility libraries to create "ICS looking" apps, that look the same all the way back to version 1.6. You get the latest features like the ActionBar, with tabs, overflow, split action bar, viewpager etc.

Bonus 2

The best way to communicate between fragments are intents. When you press something in a Fragment you would typically call StartActivity() with data on it. The intent is passed on to all fragments of the activity you launch.

Android – how to find distance using google places api

I Think As you said- you want to refrain yourself from using

any mathematical formula so you can Also try this-

You can get distance from address of location

http://maps.googleapis.com/maps/api/distancematrix/xml?origins="+a+"&destinations="+b+"&mode=driving&language=en-EN&sensor=false with a=addressFrom, b=addressTo

If you have lat,long of location, you can get address of that location as:

 double latiTude = 10.3929393;
 double longiTude = 150.93984884;

 Geocoder geocoder = new Geocoder(getBaseContext(), Locale.getDefault());
  GeoPoint p= new GeoPoint((int) (latiTude * 1E6), (int) (longiTude * 1E6));
  List<Address> address = geocoder.getFromLocation(
                                                    p.getLatitudeE6() / 1E6,
                                                    p.getLongitudeE6() / 1E6, 1);
    if (address.size() > 0) 
    {
    String addressFroLatLong= "";
    for (int i = 0; i < address.get(0).getMaxAddressLineIndex(); i++) 
    {   addressFroLatLong+= address.get(0).getAddressLine(i) + "\n";
    }   
   }

PLease upvote if helped. nothing else. Thanks, happy to help enjoy..
