Getting Started

Before You Begin​

This SDK is stored in the private maven repo and developed for use with the Cloudike Backend. If you need access, please Contacts Us

Requirements​

Installation​

To enable library in your app, you should add a link to our private repository in the application-level Gradle file (usually app / build.gradle). Then, add a dependency for the libraries cloudikecontacts и cloudikelog as shown below:

// ...
repositories {
  
    // ...
    maven {
        url "https://rt.cloudike.com/artifactory/libs-release-local"
        credentials {
            username = "${artifactory_username}"
            password = "${artifactory_password}"
        }
    }
}

// ...
dependencies {
    implementation "com.cloudike.cloudikecontacts:cloudikecontacts:5.2.7"
    implementation "com.cloudike.cloudikelog:cloudikelog:1.2.2"
}

Initialization​

Initialization is performed in two stages.

Stage 1. Initialize library​

The best place for the first stage is the method Application.onCreate(). The first step is to initialize the library Logger. Optionally, you can implement initRxErrorHandler() to log errors that occur in RxJava2.

private lateinit var contactManager: ContactManager

override fun onCreate() {
    super.onCreate()
    // ... 

    // Initialize logger first because Contact SDK uses it
    Logger.init(applicationContext)
    Logger.setDebugMode(true)

    // Optionaly
    // initRxErrorHandler()

    // Initialize library
    ContactManager.initInstance(
        context = applicationContext,
        competitionMode = ContactManager.CompetitionMode.STANDALONE,
        competitorPackageName = "com.package.name.sample_package",
        canScheduleBackup = true,
        allowNetworkUsageInRoaming = true)

    contactManager = ContactManager

    // ...
}

Lastly, initialize the contacts library using the method ContactManager.initInstance().

If you need to use the custom parametersSSL Socket Factory and Trust Manager, use the following guide.

Stage 2. Preparation for work.​

After user has logged in, it is necessary to call ContactManager.prepareToWork() for work:

ContactManager.prepareToWork(
    baseUrl = "Base URL of the backend",
    token = "Mountbit-Auth token received after user login",
    profileId = "User profile id",
    userAgent = "User agent string",
    deviceId = "Unique device id")

Optionally: initialization of the RxJava2 error handler​

To log errors that occur in RxJava2, it is advisable to initialize the handler:

private fun initRxErrorHandler() {
    RxJavaPlugins.setErrorHandler(Consumer { exception ->
        var e: Throwable? = exception
        if (e is UndeliverableException) {
            e = e.cause
        }
        if (e is OnErrorNotImplementedException) {
            // error received by observer that does not provide onError handler
            if (e.cause != null) {
                e = e.cause
            }
        }
        if (e is IOException || e is SocketException) {
            // fine, irrelevant network problem or API that throws on cancellation
            Logger.main().i("RxErrorHandler", "Exception caught", e)
            return@Consumer
        }
        if (e is InterruptedException) {
            // fine, some blocking code was interrupted by a dispose call
            Logger.main().i("RxErrorHandler", "Exception caught", e)
            return@Consumer
        }
        if (e is NullPointerException ||
            e is IllegalArgumentException ||
            e is UnsupportedOperationException) {
            // that's likely a bug in the application
            Logger.main().e("RxErrorHandler", "Exception caught", e)
            Thread.currentThread().uncaughtExceptionHandler
                .uncaughtException(Thread.currentThread(), e)
            return@Consumer
        }
        if (e is IllegalStateException) {
            Logger.main().e("RxErrorHandler", "Exception caught", e)
            // that's a bug in RxJava or in a custom operator
            Thread.currentThread()
                .uncaughtExceptionHandler
                .uncaughtException(Thread.currentThread(), e)
            return@Consumer
        }
        Logger.main().w("RxErrorHandler",
            "Undeliverable exception received, not sure what to do", e)
    })
}
