UIKit freamwork is a 100% native layout and devices specific layout. It has auto adjustment of UI based on device and its orientation.

How to use Android Video UIKit?

Follow these steps:

• Step#1: Download latest Android SDK (Android Archive Library)
• Step#2: Download latest Android UIKit (Android Archive Library)
• Step#3: Add downloaded AAR files to the lib folder.
• Step#4: Go to your Project’s root directory and edit build.gradle by placing the following code in the allprojects.repositories section:

allprojects{ 
repositories { 
		flatDir { 
			dirs 'libs' 
		} 
	} 
}

• Step#5: Go to your application level build.gradle file and add the following code in the dependencies section:

implementation fileTree(dir: 'libs', include: ['*.aar', '*.jar'], exclude: []) 
implementation('io.socket:socket.io-client:1.0.1') { 
	exclude group: 'org.json', module: 'json' 
} 
implementation 'org.webrtc:google-webrtc:1.0.32006' 

Define Device Permissions

Define permissions in AndroidMainfest.xml as shown below:

<uses-permission android:name="android.permission.CAMERA" /> 
<uses-permission android:name="android.permission.RECORD_AUDIO" /> 
<uses-permission android:name="android.permission.INTERNET" />

<uses-permission android:name="android.permission.BLUETOOTH_SCAN"android:usesPermissionFlags="neverForLocation"/> 
<uses-permission android:name="android.permission.BLUETOOTH_ADVERTISE" /> 
<uses-permission android:name="android.permission.BLUETOOTH_CONNECT" /> 

Implementation

Prerequisite

To use the Enx_UIKit_Android Framework user must have the following:

• A valid Token to join the room.
• Camera Permission
• Mic Permission

Code a little

• Step#1: Go to your Activity and import the packages shown below:

import com.enablex.enxuikit_android.observer.EnxVideoStateObserver 
import com.enablex.enxuikit_android.view.EnxVideoView 

• Step#2: Initialize the EnxVideoView class and then add the reference of EnxVideoView to your layout as shown below:

// You need to get Token to get connected
// Refer:https://www.enablex.io/developer/video-api/server-api/rooms-route/#create-token

// Initialize EnxVideoView
enxVideoView = EnxVideoView(this,token,this)

// Set Layout Parameters
val rlp = RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT)

// Add VideoView to your Layout
this.addContentView(enxVideoView, rlp) 

• Step#3: Handle Orientation

To handle Orientation please follow below 2 steps:

• Add the property given below to your activity inside AndroidMainfest.xml file:

android:configChanges="orientation|screenSize|keyboardHidden"

• Overide onConfigurationchanged function and call below function

enxVideoView?.configurationChanged(newConfig)

override fun onConfigurationChanged(newConfig: Configuration) { 
    super.onConfigurationChanged(newConfig) 
    enxVideoView?.configurationChanged(newConfig) 
} 

• Step#4: Handle Back Button

To handle the back button please follow step:

• Overide onBackPressed function and call below function    

override fun onBackPressed() {
    enxVideoView?.backPressed() 
}

• Step#5: Customize Bottom Bar

You can design the Bottom Bar according to you needs and you can set the desired sequence by passing a list of EnxButton to configureBottomOptionList function. While creating your own button use the setImage function and pass two images (first image for normal state and second image for selected state) except the disconnect button as it takes a single parameter for the image. For more detail, please refer to below code snippet:

val setting = EnxSetting.getInstance(this) 

// Enumerated values to use for BottomOption are
// AUDIO, VIDEO, SWITCH_CAMERA, SWITCH_AUDIO, GROUP_CHAT, DISCONNECT 

val audioButton = EnxButton(this,EnxSetting.BottomOption.AUDIO.tag) 
audioButton.setImage(R.drawable.audio_on,R.drawable.audio_off) 

val chatButton = EnxButton(this,EnxSetting.BottomOption.GROUP_CHAT.tag) 
chatButton.setImage(R.drawable.group_chat,R.drawable.group_chat_noti) 

val disconnectButton = EnxButton(this,EnxSetting.BottomOption.DISCONNECT.tag) 
disconnectButton.setImage(R.drawable.end_call_new) 
 
setting.configureBottomOptionList(listOf<EnxButton>(videoButton, cameraSwitch, chatButton, audioButton, disconnectButton)) 

• Steps#6 Customize Top Bar

You can design the Top Bar according to your needs and they can set the desired sequence by passing a list of EnxButton to configureTopOptionList function. For example, while creating your own button for REQUEST_FLOOR use the setImage function and pass two images (first image for normal state and second image for selected state). But for USER_LIST and MENU setImage function takes a single parameter. For details, please follow the below code snippet:

val setting = EnxSetting.getInstance(this)

// Enumerated values to use for TopOption are
// USER_LIST, MENU, REQUEST_FLOOR 

val userList = EnxButton(this,EnxSetting.TopOption.USER_LIST.tag) 
userList.setImage(R.drawable.participant_icon) 

val webinarButton = EnxButton(this,EnxSetting.TopOption.REQUEST_FLOOR.tag) 
webinarButton?.setImage(R.drawable.notification_icon, R.drawable.notification_icon_selected) 

val menu = EnxButton(this,EnxSetting.TopOption.MENU.tag) 
menu.setImage(R.drawable.ic_more_vert)  

 
setting.configureTopOptionList(listOf<EnxButton>(menu,userList, webinarButton)) 

• Steps#7 Set Background Color of Bottom Bar

You can update the background color of Bottom Bar by passing resource id of the color to updateBottomOptionView function.

val setting = EnxSetting.getInstance(this) 
setting.updateBottomOptionView(R.color.white) 

• Steps#8 Set Background Color of Top Bar

You can update the background color of Top Bar by passing resource id of the color to updateTopOptionView function.

val setting = EnxSetting.getInstance(this) 
setting.updateTopOptionView(R.color.white) 

• Steps#9 Handle Disconnection and Correction Error

Here you need to create an instance of EnxVideoView class which is the subclass of RelativeLayout. You also need to pass a reference of Activity, a valid Token, and Observer to receive callback. 

There are 2 callbacks for you to clear instance or for any other UI/UX implementation. You need to override these functions below:

• For Disconnection: You get notified when the user gets disconnected from the Video Room. The JSON you receive shows reason for disconnection.

override fun disconnect(jsonObject: JSONObject?) 

• For Connection Error: You get notified if the user doesn’t get connected to the Video Room. The JSON you receive shows related error.

override fun connectError(jsonObject: JSONObject?)
