Step 8 : The downloaded ZIP folder will contain a set of AAR filesThese files constitute a sample app, SDK files and UI Kit needed for integrating chat into your Android app
Now that you have completed the initial preparation, the next step is to start with the SDK integration process.
Step 1 : Android Studio IDE
Step 2 : Create a new project or Open an existing project
Step 3 : Add the following libraries to your project:
appbase.aar
flycommons.aar
flynetwork.aar
flydatabase.aar
videocompression.aar
xmpp.aar
Step 4 : Configure the methods compileOptions, kotlinOptions and packagingOptions in the app/build.gradle file
plugins {
...
id 'kotlin-android'
id 'kotlin-kapt'
}
android {
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
kotlinOptions {
jvmTarget = '1.8'
}
packagingOptions {
exclude 'META-INF/AL2.0'
exclude 'META-INF/DEPENDENCIES'
exclude 'META-INF/LICENSE'
exclude 'META-INF/LICENSE.txt'
exclude 'META-INF/license.txt'
exclude 'META-INF/NOTICE'
exclude 'META-INF/NOTICE.txt'
exclude 'META-INF/notice.txt'
exclude 'META-INF/ASL2.0'
exclude 'META-INF/LGPL2.1'
exclude("META-INF/*.kotlin_module")
}
}
Step : 5 Add the following dependencies in the app/build.gradle file.
dependencies {
... // your app dependencies
implementation files('libs/appbase.aar')
implementation files('libs/flycommons.aar')
implementation files('libs/flynetwork.aar')
implementation files('libs/flydatabase.aar')
implementation files('libs/videocompression.aar')
implementation files('libs/xmpp.aar')
}
Step 6 : Call the following classes in the app/build.gradle file:
dependencies {
... // your app dependencies
configurations {
all {
exclude group: 'org.json', module: 'json'
exclude group: 'xpp3', module: 'xpp3'
}
}
//For lifecycle listener
implementation 'android.arch.lifecycle:extensions:1.1.1'
annotationProcessor 'android.arch.lifecycle:compiler:1.1.1'
//For GreenDao
implementation 'de.greenrobot:greendao:2.1.0'
//For gson parsing
implementation 'com.google.code.gson:gson:2.8.1'
//for smack implementation
implementation 'org.igniterealtime.smack:smack-android:4.4.4'
implementation 'org.igniterealtime.smack:smack-tcp:4.4.4'
implementation 'org.igniterealtime.smack:smack-im:4.4.4'
implementation 'org.igniterealtime.smack:smack-extensions:4.4.4'
implementation 'org.igniterealtime.smack:smack-sasl-provided:4.4.4'
implementation 'androidx.localbroadcastmanager:localbroadcastmanager:1.0.0'
implementation 'androidx.multidex:multidex:2.0.1'
implementation 'com.google.android.gms:play-services-location:17.0.0'
//Dagger Dependencies
api 'com.google.dagger:dagger:2.40.5'
kapt 'com.google.dagger:dagger-compiler:2.40.5'
api 'com.google.dagger:dagger-android:2.40.5'
api 'com.google.dagger:dagger-android-support:2.40.5'
kapt 'com.google.dagger:dagger-android-processor:2.40.5'
//coroutines
implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-android:1.3.3'
implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-test:1.3.3'
//apicalls
implementation 'com.squareup.retrofit2:retrofit:2.6.1'
implementation 'com.squareup.retrofit2:converter-gson:2.6.1'
implementation 'com.squareup.okhttp3:okhttp:4.2.0'
implementation 'com.jakewharton.retrofit:retrofit2-kotlin-coroutines-adapter:0.9.2'
//stetho interceptor
implementation 'com.facebook.stetho:stetho-okhttp3:1.3.1'
//okhttp interceptor
implementation 'com.squareup.okhttp3:logging-interceptor:3.14.3'
//shared preference encryption
implementation 'androidx.security:security-crypto:1.1.0-alpha03'
}
Step 7 : to avoid library conflicts, add the below line in the gradle.properties file
<uses-permissionuses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
Step 8 : In the AndroidManifest.xml manifest, add the following permissions
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
To configure the MirrorFly Chat SDK in your Android app, add the following into the app/build.gradle file:
buildTypes {
debug {
buildConfigField 'String', 'SDK_BASE_URL', '"https://api-preprod-sandbox.mirrorfly.com/api/v1/"'
buildConfigField 'String', 'LICENSE', '"xxxxxxxxxxxxxxxxxxxxxxxxx"'
buildConfigField 'String', 'WEB_CHAT_LOGIN', '"https://webchat-preprod-sandbox.mirrorfly.com/"'
buildConfigField "String", "SUPPORT_MAIL", '"contussupport@gmail.com"'
}
}
To initialize the Chat SDK,
Step 1 : Navigate to your Application class
Step 2 : In the onCreate() method, use the following ChatSDK Builder
//For chat logging
LogMessage.enableDebugLogging(BuildConfig.DEBUG);
ChatSDK.Builder()
.setDomainBaseUrl(BuildConfig.SDK_BASE_URL)
.setLicenseKey(BuildConfig.LICENSE)
.setIsTrialLicenceKey(true)
.build();
//For chat logging
LogMessage.enableDebugLogging(BuildConfig.DEBUG)
ChatSDK.Builder()
.setDomainBaseUrl(BuildConfig.SDK_BASE_URL)
.setLicenseKey(BuildConfig.LICENSE)
.setIsTrialLicenceKey(true)
.build()
To run the app, we will need a user registered to the App. Use the below method to create an user in the sandbox live mode, based on the setIsTrialLicenceKey provided.
FlyCore.registerUser(USER_IDENTIFIER, (isSuccess, throwable, data ) -> {
if(isSuccess) {
JSONObject responseObject = (JSONObject) data.get("data");
// Get Username and password from the object
} else {
// Register user failed print throwable to find the exception details.
}
});
FlyCore.registerUser(USER_IDENTIFIER) { isSuccess, throwable, data ->
if(isSuccess) {
val responseObject = data.get("data") as JSONObject
// Get Username and password from the object
} else {
// Register user failed print throwable to find the exception details.
}
}
Once an user is registered, the app must establish a connection with the server to initialize the chat connection. This process will implement the capability of sending and receiving messages from one user to another.
| Argument | Type | Description |
|---|---|---|
| CALLBACK | ChatConnectionListener | callback listener for chat connection |
ChatManager.connect(new ChatConnectionListener() {
@Override
public void onConnected() {
// Write your success logic here to navigate Profile Page or
// To Start your one-one chat with your friends
}
@Override
public void onDisconnected() {
// Connection disconnected
//No need implementations
}
@Override
public void onConnectionNotAuthorized() {
// Connection Not authorized
//No need implementations
}
});
ChatManager.connect(object : ChatConnectionListener {
override fun onConnected() {
// Write your success logic here to navigate Profile Page or
// To Start your one-one chat with your friends
}
override fun onDisconnected() {
// Connection disconnected
//No need implementations
}
override fun onConnectionNotAuthorized() {
// Connection Not authorized
//No need implementations
}
})
The below method is used to send the messages. For this, we will need a unique user ID. Call the other user's username method String userJID = FlyUtils.getJid(USERNAME) to generate the unique user ID.
| Argument | Type | Description |
|---|---|---|
| USER_IDENTIFIER | String | JID of the end user |
| TEXT | String | Indicates the text message that needs to be sent |
| REPLY_MESSAGE_ID | String | Specifies the Message ID of replied message |
| CALLBACK | SendMessageListener | callback to observe the action status |
FlyMessenger.sendTextMessage(TO_JID, TEXT, new SendMessageListener() {
@Override
public void onResponse(boolean isSuccess, @Nullable ChatMessage chatMessage) {
// you will get the message sent success response
}
});
FlyMessenger.sendTextMessage(TO_JID, TEXT, listener = object : SendMessageListener {
override fun onResponse(isSuccess: Boolean, chatMessage: ChatMessage?) {
// you will get the message sent success response
}
})
Observe all the incoming messages and other feature listeners by extending the FlyBaseActivity from SDK into your app BaseActivity
public class MainActivity extends FlyBaseActivity { }
class MainActivity : FlyBaseActivity()
Only when the other user sends a message and is received at the user’s end, the listeners will be called.
@Override
public void onMessageReceived(@NonNull ChatMessage message) {
super.onMessageReceived(message);
// received message object
}
override fun onMessageReceived(message: ChatMessage) {
super.onMessageReceived(message)
// received message object
}
