Cordova vk plugin does not work

After installing https://github.com/akveo/cordova-vk/

cordova plugin add cordova-vk --variable VK_APP_ID=…

It says about adding vksdk_library You should add

'android.library.reference.2=vksdk_library' to project.properties

If add it to my platforms\android\project.properties as

android.library.reference.1=CordovaLib
android.library.reference.2=app
android.library.reference.3=vksdk_library

in build time i got error * What went wrong: A problem occurred configuring project ‘:vksdk_library’.

Cannot read packageName from C:\games\cordova\gamename\platforms\android\vksdk_library\src\main\AndroidManifest.xml

The file looks like this:
<?xml version="1.0" encoding="utf-8"?>

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="19" />

    <application>
        <activity android:name="com.vk.sdk.VKOpenAuthActivity" />
    </application>

</manifest>

If i do not add vksd_library to the project i got nothing happen in
when i use VkSdk.init(‘123456’)

Maybe i can go without “vksdk_library”?
