In this post I explain how to load and send data from SOAP web service in your android application. What is SOAP? SOAP is a standards-based web services technology that allows providers to abstract data and transport implementations over the web. It relies on Extensible Markup Language (XML) for its message format, and usually relies on other Application Layer protocols, most notably Hypertext Transfer Protocol (HTTP) and Simple Mail Transfer Protocol (SMTP), for message negotiation and transmission. Now we will see it though an example(here the data is fetch from web and set in drop-down) Step 1. Create new project in Android Studio. Step 2.  Before we start creating our project we need external library for SOAP to load data from SOAP based web service. I use KSOAP2 library to load and send data to service. You download from here  or add the dependencies in build.gradle as given, compile 'com.google.code.ksoap2-android:ksoap2-android:3.1.1' and r

In this tutorial, we will see about how to design an Android layout for chat application using Chat Bubbles  and the main part is chat via Bluetooth . Main objective of this post is to give an idea about how to allow two-way text chat over Bluetooth in android. Bubbles: Chat bubbles are background image that expands horizontally and vertically as required based on the message posted. Bubbles are Nine-patch Images. Image Nine-patch Image In creating Android chat bubbles, nine-patch image plays a crucial role.  Nine-patch image  is a bitmap which stretches to fit the content posted in the View where it is applied as a background. A NinePatch drawable is a standard PNG image that includes an extra 1-pixel-wide border. It must be saved with the extension  .9.png , and saved into the  res/drawable/  directory of your project. The border is used to define the stretchable and static areas of the image. You indicate a stretchable section by drawing one (or more) 1-pixel-w

What is Volley library exactly for? Android volley is a networking library was introduced to make networking calls much easier, faster without writing tons of code. By default all the volley network calls works asynchronously, so we don’t have to worry about using asynctask anymore. Advantages of using Volley: Volley automatically schedule all network requests. It means that Volley will be taking care of all the network requests your app executes for fetching response or image from web. Volley provides transparent disk and memory caching. Volley provides powerful cancellation request API. It means that you can cancel a single request or you can set blocks or scopes of requests to cancel. Volley provides powerful customization abilities. Volley provides Debugging and tracing tools. How to add Volley Library? Open build.gradle located under your app module and add below dependencies. compile ' com.mcxiaoke.volley:library:1.0.19 ' After addin
