MODULE_UNAVAILABLE Error in Dynamic Module in Android

Question

Recently in 2018, Google has announced new feature in Android called Dynamic Feature Module

I tried same feature from this link http://www.tellmehow.co/know-android-dynamic-delivery-module/#

In my project, I got module app which is my application and dynamic module as bigbazaar,

I am using following method to download dynamic method at runtime.

private void downloadDynamicModule() {
    try {
        SplitInstallManager splitInstallManager =
                SplitInstallManagerFactory.create(this);

        SplitInstallRequest request =
                SplitInstallRequest
                        .newBuilder()
                        .addModule("bigbazaar")
                        .build();

        SplitInstallStateUpdatedListener listener = new SplitInstallStateUpdatedListener() {
            @Override
            public void onStateUpdate(SplitInstallSessionState splitInstallSessionState) {
                if (splitInstallSessionState.sessionId() == mySessionId) {
                    switch (splitInstallSessionState.status()) {
                        case SplitInstallSessionStatus.INSTALLED:
                            Toast.makeText(MainActivity.this,
                                    "Dynamic Module downloaded", Toast.LENGTH_SHORT).show();
                            cmdBigBazaar.setEnabled(true);
                            break;
                    }
                }
            }
        };

        splitInstallManager.registerListener(listener);

        splitInstallManager.startInstall(request)
                .addOnFailureListener(new OnFailureListener() {
                    @Override
                    public void onFailure(Exception e) {
                        switch (((SplitInstallException) e).getErrorCode()) {
                            case SplitInstallErrorCode.MODULE_UNAVAILABLE:
                                Toast.makeText(MainActivity.this, "MODULE_UNAVAILABLE", Toast.LENGTH_SHORT).show();
                        }
                    }
                })
                .addOnSuccessListener(new OnSuccessListener<Integer>() {
                    @Override
                    public void onSuccess(Integer sessionId) {
                        mySessionId = sessionId;
                    }
                });

    } catch (Exception e) {
        e.printStackTrace();
    }
}

From the given link & other bolgs, I found that we can test this feature via Google Play Store and at our end using a tool called "bundletool"

I have also change my Run configuration as per suggested in example link.

I have also define following attributes in my dynamic feature module's AndroidManifest.xml file,

<dist:module
    dist:onDemand="true"
    dist:instant="false"
    dist:title="@string/title_bigbazaar">

    <dist:fusing dist:include="false" />
</dist:module>

Question

I have tried many ways but everytime when I click on download button to download dynamic module, it is giving me error code -2 which is "MUDULE_UNAVAILABLE".

How can I solve this error ?

Answer 1

You can't test on-demand module delivery using bundletool. (Read the final note on this article: https://proandroiddev.com/dynamic-feature-module-android-ondemand-module-android-app-bundle-ea0d872b32d)

You should instead upload your bundle to internal app sharing (or some other testing track), share it via link to your device and then test on-demand delivery.
