Update

A library which helps to reduce the time to support in-app updates outside of the Play Store.

Publishing

Publishing can be done by running the following command (MavenLocal)

./gradlew publishReleasePublicationToMavenLocal

Installation

Add this to your root build.gradle file:

allprojects {
    repositories {
        maven { url "https://www.jitpack.io" }
    }
}

Add the library to the app/build.gradle file:

implementation "com.github.wesleydonk:update:update-core:{latest_version}"
implementation "com.github.wesleydonk:update:update-fetcher-pov3:{latest_version}"
implementation "com.github.wesleydonk:update:update-fetcher-pov4:{latest_version}"
implementation "com.github.wesleydonk:update:update-ui:{latest_version}"

implementation "com.github.wesleydonk:update:update-core-no-op:{latest_version}"
implementation "com.github.wesleydonk:update:update-ui-no-op:{latest_version}"
implementation "com.github.wesleydonk:update:update-fetcher-no-op:{latest_version}"

implementation "com.github.wesleydonk:update:update-ui-automation:{latest_version}"
implementation "com.github.wesleydonk:update:update-ui-automation-no-op:{latest_version}"

Features

• Provide in-app updates
• Separate artifacts for Tryoutapps, which uses Prince of Versions.
• Download and update .apk files directly from within the app itself when required.

Usage

There is a sample available in the repository. All that it requires is:

val url = "<link to configuration file>"
val fetcher = PrinceOfVersionFetcher(this, url)

val config = UpdateConfig.Builder()
    .fetcher(fetcher)
    .build(this)

val update = Update.Builder()
    .config(config)
    .build()

lifecycleScope.launch {
    update.synchronize()
    
    update.getLatestVersion().collect { version ->
        version.showUpdateDialogFragment(supportFragmentManager)
    }
}

When using the ui-automation library, it is possible to synchronize the Update from the Application class:

val update = Update.Builder()
    .config(config)
    .build()

update.synchronize(this, AutomationStrategy.DIALOG_FRAGMENT)

Connecting to a CI

By providing the config url dynamically from the CI, it can be parsed by the client app. Depending on the job/workflow that is running on the CI, the CONFIG_URL can be different. An empty string will be used whenever there is no url set in the environment.

Add the following in the app/build.gradle file:

def UPDATE_CONFIG_URL = 'UPDATE_CONFIG_URL'
def STRING = 'String'

android {
    defaultConfig {
        ...
        buildConfigField STRING, UPDATE_CONFIG_URL, '"' + getConfigUrl() + '"'
    }
}

static def getConfigUrl() {
    return System.getenv('CONFIG_URL') ?: ''
}

Providing the config url as buildconfig property makes it a breeze to use it in the above example.

Replace

val url = "<link to configuration file>"

with

val url = BuildConfig.UPDATE_CONFIG_URL
