Let’s start with the code
Let’s start with the code

Create an Android Project (App Module) Goto File-> New ->
New Module and select Dynamic Feature Module (>Kitkat)

On the next screen, you will get a few options
to configure your module.

Press Finish :)
Final Project Looks like :)
What we want to achieve ?
<RelativeLayout> <Button android:id="@+id/buttonClick"/> <Button android:id="@+id/buttonOpenNewsModule android:visibility="gone"/> <Button android:id="@+id/buttonDeleteNewsModule" android:visibility="gone"/> </RelativeLayout>
android { ....... dynamicFeatures = [":news_feature"] } In app’s build.gradle
file
apply plugin: 'com.android.dynamic-feature' dependencies { ..... implementation project(':app') } In
new_feature’s build.gradle file
<dist:module dist:instant="false" dist:onDemand="true" dist:title="@string/title_news_feature"> <dist:fusing dist:include="true"/> </dist:module> In the manifest
of the dynamic Module,
<dist:module dist:instant="false" dist:onDemand="true" dist:title="@string/title_news_feature"> <dist:fusing dist:include="true"/> </dist:module>
<dist:module dist:instant="false" dist:onDemand="true" dist:title="@string/title_news_feature"> <dist:fusing dist:include="true"/> </dist:module>
implementation 'com.google.android.play:core:1.6.3' To make your module downloadable on demand add
the following in the app-module's build.gradle,
Pro Tip #1 • Treat the dynamic-module as the individual
app itself
dependencies { ..... api 'androidx.appcompat:appcompat:1.0.2' api 'androidx.constraintlayout:constraintlayout:1.1.3' implementation 'com.google.android.play:core:1.6.1' }
In the manifest of the app’s module,
This is our project
dependencies { ..... api 'androidx.appcompat:appcompat:1.0.2' api 'androidx.constraintlayout:constraintlayout:1.1.3' implementation 'com.google.android.play:core:1.6.1' }
In the manifest of the app’s module,
dependencies { ..... api 'androidx.appcompat:appcompat:1.0.2' api 'androidx.constraintlayout:constraintlayout:1.1.3' implementation 'com.google.android.play:core:1.6.1' }
In the manifest of the app’s module,
Let's learn how to make the dynamic-feature downloadable from the
app's module.
class MainActivity : AppCompatActivity() { lateinit var splitInstallManager: SplitInstallManager lateinit
var request: SplitInstallRequest val DYNAMIC_FEATURE = "news_feature" override fun onCreate(savedInstanceState: Bundle?) { .... } } In App’s MainActivity
override fun onCreate(savedInstanceState: Bundle) { .... initDynamicModules() } private fun
initDynamicModules() { splitInstallManager = SplitInstallManagerFactory.create(this) request = SplitInstallRequest .newBuilder() .addModule(DYNAMIC_FEATURE) .build(); } In App’s MainActivity
Implement Clicks :)
In App’s MainActivity override fun onCreate(savedInstanceState: Bundle) { ........ buttonClick.setOnClickListener
{ if (!isDynamicFeatureDownloaded(DYNAMIC_FEATURE)) { downloadFeature() } else { buttonDeleteNewsModule.visibility = View.VISIBLE buttonOpenNewsModule.visibility = View.VISIBLE } } }
In App’s MainActivity private fun isDynamicFeatureDownloaded(feature: String): Boolean = splitInstallManager.installedModules.contains(feature)
In App’s MainActivity private fun downloadFeature() { splitInstallManager.startInstall(request) .addOnFailureListener {
//on Failure Handle } .addOnSuccessListener { buttonOpenNewsModule.visibility = View.VISIBLE buttonDeleteNewsModule.visibility = View.VISIBLE } .addOnCompleteListener { } }
None
Let’s Open the News Activity
In App’s MainActivity buttonOpenNewsModule.setOnClickListener { val intent = Intent() .setClassName(this,
"com.mindorks.news_feature.newsloader.NewsLoaderActivity") startActivity(intent) }
In App’s MainActivity buttonOpenNewsModule.setOnClickListener { val intent = Intent() .setClassName(this,
"com.mindorks.news_feature.newsloader.NewsLoaderActivity") startActivity(intent) }
In App’s MainActivity buttonDeleteNewsModule.setOnClickListener { val list = listOf(DYNAMIC_FEATURE) splitInstallManager.deferredUninstall(list)
.addOnSuccessListener { buttonDeleteNewsModule.visibility = View.GONE buttonOpenNewsModule.visibility = View.GONE } }
Library Modules
Create an Android Project (App Module) Goto File -> New
-> New Module
None
And Use it how you use other libraries :)
Pro Tip #2 • Checkout Darshan’s Talk to understand this
module for the library creation
