  • Parse the “overview_polyline” from the JSON by providing the appropriate GET parameters. For eg:” +
+ “transit_routing_preference=less_driving&”
+ “origin=” + latitude + “,” + longitude + “&”
+ “destination=” + destination + “&”
+ “key=” + getResources().getString(R.string.google_directions_key)

  • Decode the polyline which will provide you with list of latitudes and longitudes that is List<LatLng> to be apt.
  • Create a value animator by providing the ofFloatValue, setting duration and adding update listener in Handler

ValueAnimator valueAnimator = ValueAnimator.ofFloat(0, 1);
valueAnimator.setInterpolator(new LinearInterpolator());
valueAnimator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
public void onAnimationUpdate(ValueAnimator valueAnimator) {

  • Finally set position of marker to the new position, also evaluating the bearing between the consecutive points so that it seems car is turning literally and finally update camera as:

marker.setAnchor(0.5f, 0.5f);
marker.setRotation(getBearing(startPosition, newPos));
(new CameraPosition.Builder()

Recently we discuss about Kotlin Native and daily used kotlin code, today we are going to discuss about Google’s Material Shadow library.

Add Material Shadow in Android

Material Shadow is a library for seamlessly integrating Material shadows. The library takes existing material shadows to next level by adding the following features :

  • Convex shadows : The shadows are not only rectangular or circular, they can take any convex shape depending on the view and its content.
  • Support for shadow offsets : The library allows developers to set X and Y offset for the shadows.
  • Support for shadow intensity : The library also has support for setting shadow intensity via shadowAlpha attribute.
  • Shadows for semi-transparent views : The library allows shadows for semi-transparent views.
  • Support for Async Shadow calculations : The library allows the operations to be async to avoid blocking the UI thread for long calculations.
  • Shadow animations : The library supports fade out animation for shadow.

How to use this library?

Just add the following dependency in your app’s build.gradle

dependencies {
compile ‘com.sdsmdg.harjot:materialshadows:1.2.5’

iPhone 8 will come with Samasung oLED like display 

iPhone 8 will have Samasung oLED like display

Samsung is developing many next generation display technologies supported OLEDs. Samsung has been developing a folding OLED device for a protracted time – which can dramatically change the mobile device market because it may enable smartphone to turn into tablets or phones that may be folded into smaller devices.

But Samsung display can doubtless not be the only supplier of OLED screens going forward, as several other screen manufacturers are adapting their production lines to deal with Apple’s iPhone needs — and Apple isn’t aiming to be the only smartphone maker which will want lots of OLED screens in the future.

Create First Android Kotlin application

Welcome to this series of articles where we are going to learn Kotlin, a new JVM language, while developing an Android App. I hope it will help you to learn this incredible language in the context of Android. This stories will be separated in different Parts. In the Content section you will have the different Parts and the main topics that are going to be discussing there, each Part will include different Kotlin features.

How to make Reddit like Android Kotlin app

My intention is not to create the best App in the world (I can’t do that hahah) but I’ll try to explain Kotlin and it’s main features while developing this app.

Libraries that we are going to use:

  • Retrofit 2.0: To consume public Reddit API.
  • RxJava: We will use Observables to decouple the UI thread with our background tasks. In this case to call the API and return this values to the UI.
  • Picasso: Load images from Reddit.
  • RecyclerView: We will use the RecyclerView to present the information and also to provide the infinite scroll behaviour.
  • Kotlin Android Extensions: to bind the UI (Views) with code.
  • Dagger 2: Dependency Injection
