Hi Manish,
to generate the Mobile Project and test as you can see in the Online Training Lesson, you need to use the "Generate and Run" button.
Instead, if you want to create an apk or ipa to load on the store or to install on the device, you can use the "Build" button and refer to the following articles that explain how to build and test an app with Android or iOS device:
- How to build for Adroid device http://my.webratio.com/learn/learningobject/how-to-build-and-test-an-android-application-v-80
- How to build for iOS device http://my.webratio.com/learn/learningobject/how-to-build-and-test-an-ios-application-v-80
Best regards,
