BLOCKv SDK for Android

This is the official BLOCKv SDK. It allows you to easily integrate your own apps into the BLOCKv Platform. It handles a number of operations on your behalf, including:

• Wrapping API endpoints,
• Parsing JSON to native Java models,
• Managing OAuth2 tokens,
• Interacting with the web socket, and
• Visually representing vAtoms using faces. (new)

Requirements

• Android API 19+
• Kotlin

The BLOCKv SDK is dependant on Kotlin, if your version of Android Studio < 3.0 you will need to install it. Go to File | Settings | Plugins | Install JetBrains plugin… and then search for and install Kotlin. If you are looking at the "Welcome to Android Studio" screen, choose Configure | Plugins | Install JetBrains plugin… You'll need to restart the IDE after this completes.

Install and configure the SDK

Add the BLOCKv maven repository and Kotlin plugin to the root-level build.gradle file:

buildscript {
  ext.kotlin_version = '1.2.61'
  //...
  dependencies {
    //...
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
  }
}
allprojects {
  //...
  repositories {
    //...
    maven {
      url "https://maven.blockv.io/artifactory/BLOCKv"
    }
  }
}

Next, add the Kotlin plugin and following dependencies to your module Gradle file (usually the app/build.gradle):

apply plugin: 'kotlin-android' //This should be at the top of the file.
// ...
//
dependencies {
  // ...
  implementation 'io.blockv.sdk:face:3.0.1'
  // Make sure android Studio version is > 3.0 or include the Kotlin Plugin
  implementation 'org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version'
}

Finally, add the following uses-permission element to the manifest:

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

To access the BLOCKv SDK in your application code, import the class:

import io.blockv.core.Blockv;

Configure your BLOCKv integration

To configure your integration, create an instance of the BLOCKv SDK.

public class ExampleActivity extends Activity
{ 
  //...
  protected void onCreate(Bundle savedInstanceState) {
    //...
    //BLOCKv instance should be maintained as a singleton
    Blockv blockv = new Blockv(this,"Your app id"); 
  }
}

At this point you will need an App Id. See FAQ

Example

Please see the BLOCKv Android Sample for an example on using the BLOCKv SDK.

Dependencies

1. nv-websocket-client is used for the web socket.

Recommendations

We recommend you use Dagger 2, or a similar library, for singleton management for the BLOCKv SDK.
