Question

I am working on the dynamic feature module. I uploaded the .aab file into playstore some times app is unable to open the module throwing the error like this.

This is the error getting in logcat:

java.lang.RuntimeException: Unable to instantiate activity 

ComponentInfo{com.testDynamic/com.testDynamic.zco.ZcoActivity}: 
java.lang.ClassNotFoundException: Didn't find class 
"com.testDynamic.zco.ZcoActivity"
 on path: DexPathList[[zip file
 "/data/app/com.testDynamic-1/base.apk",
    
    

This issue here is my code.

This is my Main app manifest file:

<?xml version="1.0" encoding="utf-8"?> 

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

    <uses-permission android:name="android.permission.INTERNET" />

    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

    <dist:module dist:instant="true" />

    <application
        android:name=".Application"
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">

        <activity android:name=".MainActivity">
 
            <intent-filter>

                <action android:name="android.intent.action.MAIN" />

                <action android:name="android.intent.action.VIEW" />
                   
                <category android:name="android.intent.category.LAUNCHER" />

            </intent-filter>

        </activity>

    </application>

</manifest>

</manifest>

         versionName "3.1"
    }

    dynamicFeatures = [":dynamicmodule",":dynamic_feature2",":dynamiczco"]

    compileOptions {
        sourceCompatibility = '1.8'
        targetCompatibility = '1.8'
    }

Answer 1

Hi after researching i got the solution. Now the module was downloading without any crash.

I changed the module manifest

   <dist:module

        dist:onDemand="true"

        dist:title="@string/title_test">

        <dist:fusing dist:include="true" />

to

   <dist:module

    dist:instant="true" 

    dist:onDemand="false"

    dist:title="@string/title_test">

    <dist:fusing dist:include="true" />

</dist:module>

It is working fine. Thank you all
