Is that possible to make in app billing in Android instant apps?

Question

Here's my implementation:

private IabHelper mIabHelper;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    mIabHelper = new IabHelper(this, GOOGLE_BASE64_KEY);
    mIabHelper.startSetup(this);
}

@Override
public void onIabSetupFinished(IabResult result) {
    if (result.isSuccess()){
        mIabHelper.queryInventoryAsync(true, this);
    } else {
        Log.e("test","onIabSetupFinished-result:"+result.getMessage());
    }
}

Then I got this:

08-09 21:44:00.859 5839-5839/? D/IabHelper: IAB helper created.
08-09 21:44:00.859 5839-5839/? D/IabHelper: Starting in-app billing setup.

Google Play Billing is not yet supported with Instant Apps, but we are working on it.
