I try to implement dynamic feature module in my app. I have button in Activity. When user click I check module already installed or not. if not i start Install using startInstall(request). But I always goes to else state.

Code

 if (manager.installedModules.contains("sample")) 
-----> Always go to this block 
 Toast.makeText(this, "Already Downloaded", Toast.LENGTH_SHORT).show()
 Intent().setClassName(packageName, "com.example.sample.SampleActivity")
 .also 
 startActivity(it)
 
 else 
 // Never came to this state
 // Create request to install a feature module by name.
 val request = SplitInstallRequest.newBuilder()
 .addModule("sample")
 .build()
 // Load and install the requested feature module.
 manager.startInstall(request)
 

In Dynamic feature module I set onDemand="true"

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:dist="http://schemas.android.com/apk/distribution"
package="com.example.sample">

<dist:module
 dist:onDemand="true"
 dist:title="@string/title_sample">
 <dist:fusing dist:include="true" />
</dist:module>

<application>
 <activity android:name="com.example.sample.SampleActivity">
 <intent-filter>
 <action android:name="android.intent.action.VIEW" />
 </intent-filter>
 </activity>
</application>

Currently the only way to test your implementation of onDemand delivery is by uploading the .aab to the PlayStore.

The standard deployment from Android Studio deploys all modules to the attached device.

In a development environment the flow is correct, that the module is already installed when it's deployed to device.

As for code, take a look at the sample app, in particular the download and listener implementation of MainActivity.

add split="dynamic-feature-test" in your manifest
split="split_name" : Defines the name of the module, which your app specifies when requesting an on demand module using the Play Core Library.

use <dist:fusing dist:include="false" /> in order to exclude the feature module.

this is only required devices with API level < 20 ...in case the minSdkVersion permits this.

see the documentation, below paragraph 6 c.
