问题
I developed a hybrid mobile app integrating SalesForce Mobile SDK with Ionic using Brett Nelson's set of blog posts -
After following the set of instructions in this post - https://wipdeveloper.com/2017/06/27/saleforce-mobile-sdk-ionic-setup-mobile-sdk/ and setting up the org and running the app in Android Studio -> emulator, the app opened up alright.
After following these set of instructions - https://wipdeveloper.com/author/brettmn/page/6/
wherein I integrated (basically copy pasted) - package.json elements, resources etc. - from the CLI generated Ionic app to the SalesForce SDK project in Step 1, I cannot get to run the project in emulator.
While running, the LogCat emits the following information:

The manifest file looks like this ->
The project structure is as below ->
What is the configuration that is missing? Or incorrect?
Note: This question here seems to have a similar problem, but no resolution: Unable to instantiate application com.salesforce.androidsdk.phonegap.app.HybridApp: java.lang.ClassNotFoundException:

After step 2 in your question, you may have to remove and then re-add the platform you are targeting.
For iOS
ionic cordova platform remove ios
ionic cordova platform add ios@4.4.0
Or for Android
ionic cordova platform remove android
ionic cordova platform add android@6.2.3
If you do that and still have problems try removing and re-adding the salesforce mobile sdk.
cordova plugin remove com.salesforce
cordova plugin add https://github.com/forcedotcom/SalesforceMobileSDK-CordovaPlugin --force
