"GoogleMapsAnimations is an awesome android library to show radar and multiple types of circular ripple effects on google map.

GoogleMapsAnimations

"GoogleMapsAnimations" is an awesome first of its type android library for showing a ripple and radar animations on a google map, e.g show catchment area of an earthquake where ripples have been felt, give prominence to certain markers which need to be highlighted. Also add a ripple when your user is moving on the map and give a #PokemonGo type ripple effect and also add a radar type effect to show users that you are searching in certain area

Below samples show the ripple effect in action:

##Ripple Animation

###Default Ripple animation Just two lines of code :
Use .startRippleMapAnimation() and .stopRippleMapAnimation() methods to start and stop Animation.
Example is given below (Preview shown above in first sample)

    // mMap is GoogleMap object, latLng is the location on map from which ripple should start
          
            MapRipple mapRipple = new MapRipple(mMap, latLng, context);
            mapRipple.startRippleMapAnimation();      //in onMapReadyCallBack
    
            @Override
            protected void onStop() {
                super.onStop();
                if (mapRipple.isAnimationRunning()) {
                    mapRipple.stopRippleMapAnimation();
                }
            }
    // Start Animation again only if it is not running
            if (!mapRipple.isAnimationRunning()) {
                mapRipple.startRippleMapAnimation();
            }

###Advanced Ripple animation

Example is given below (Preview shown above in second sample)

    // mMap is GoogleMap object, latLng is the location on map from which ripple should start
          
            mapRipple = new MapRipple(mMap, latLng, context);
            mapRipple.withNumberOfRipples(3);
            mapRipple.withFillColor(Color.BLUE);
            mapRipple.withStrokeColor(Color.BLACK);
            mapRipple.withStrokewidth(10);      // 10dp
            mapRipple.withDistance(2000);      // 2000 metres radius
            mapRipple.withRippleDuration(12000);    //12000ms
            mapRipple.withTransparency(0.5f);
            mapRipple.startRippleMapAnimation();
    // Use same procedure to stop Animation and start it again as mentioned anove in Default Ripple Animation Sample

###Update center of ripple as location changes(Needed when user moves) Just one line of code is needed:
Use .mapRipple.withLatLng(LatLng changedLatlng) method anytime in future to update center of ripple.

// after implementing **LocationListener** interface to current class use:
    	@Override
    	public void onLocationChanged(Location location) {
       		mapRipple.withLatLng(new LatLng(location.getLatitude(), location.getLongitude()));
    	}
//See the sample for more help.

##Radar Animation

###Simple Clockwise Radar animation Just two lines of code :
Use .startRadarAnimation() and .stopRadarAnimation() methods to start and stop Animation.
Example is given below (Preview shown above in third sample)

    // mMap is GoogleMap object, latLng is the location on map from which ripple should start
          
            MapRadar mapRadar = new MapRadar(mMap, latLng, context);
	mapRadar.withDistance(2000);
	mapRadar.withOuterCircleStrokeColor(Color.parseColor("#fccd29"));
	mapRadar.withRadarColors(Color.parseColor("#00fccd29"), Color.parseColor("#fffccd29"));
		//withRadarColors() have two parameters, startColor and tailColor respectively
		//startColor should start with transparency, here 00 in front of fccd29 indicates fully transparent
		//tailColor should end with opaqueness, here f in front of fccd29 indicates fully opaque
	mapRadar.startRadarAnimation();      //in onMapReadyCallBack
    
            @Override
            protected void onStop() {
                super.onStop();
                if (mapRadar.isAnimationRunning()) {
                    mapRadar.stopRadarAnimation();
                }
            }

###Advanced Clockwise and AntiClockwise Radar animation

Example is given below (Preview shown above in fourth sample)

    // mMap is GoogleMap object, latLng is the location on map from which ripple should start
          
            MapRadar mapRadar = new MapRadar(mMap, latLng, context);
	mapRadar.withDistance(2000);
	mapRadar.withOuterCircleStrokeColor(Color.parseColor("#fccd29"));
	mapRadar.withOuterCircleStrokewidth(7);
	mapRadar.withOuterCircleTransparency(0.4f);
	mapRadar.withClockWiseAnticlockwise(true);		//enable both side rotation
	mapRadar.withClockwiseAnticlockwiseDuration(2);
	//withClockwiseAnticlockwiseDuration(duration), here duration denotes how much cycles should animation makes in 
	//one direction
	mapRadar.withOuterCircleFillColor(Color.parseColor("#12000000"));            
	mapRadar.withRadarColors(Color.parseColor("#00fccd29"), Color.parseColor("#fffccd29"));
		//withRadarColors() have two parameters, startColor and tailColor respectively
		//startColor should start with transparency, here 00 in front of fccd29 indicates fully transparent
		//tailColor should end with opaqueness, here f in front of fccd29 indicates fully opaque
	mapRadar.withRadarSpeed(5);	//controls radar speed
	mapRadar.withRadarTransparency(0.4f);
	mapRadar.startRadarAnimation();      //in onMapReadyCallBack
	
            @Override
            protected void onStop() {
                super.onStop();
                if (mapRadar.isAnimationRunning()) {
                    mapRadar.stopRadarAnimation();
                }
            }

###Update center of radar as location changes(Needed when user moves) Just one line of code is needed:
Use .mapRadar.withLatLng(LatLng changedLatlng) method anytime in future to update center of radar.

// after implementing **LocationListener** interface to current class use:
    	@Override
    	public void onLocationChanged(Location location) {
       		mapRadar.withLatLng(new LatLng(location.getLatitude(), location.getLongitude()));
    	}
//See the sample for more help.

#Build the sample To build the sample project, enable the project explorer under Android view, just go to res/values and find google_maps_api.xml(debug). Generate a google maps API key for yourself and enter it in this file, the SHA-1 fingerprint already given in the file is mine but you should generate your own. Follow these if you need some help. http://stackoverflow.com/questions/15727912/sha-1-fingerprint-of-keystore-certificate https://developers.google.com/maps/documentation/android-api/start

#Compatibility

Minimum Android SDK: This library requires a minimum API level of 11.
