Google Play In-app Billing

What is Google In-app Billing?

From Android Developer: In-app Billing is a Google Play service that lets you sell digital content from inside your applications. You can use the service to sell a wide range of content, including downloadable content such as media files or photos, virtual content such as game levels or potions, premium services and features, and more. You can use In-app Billing to sell products as:

  • Standard in-app products (one-time billing), or
  • Subscriptions (recurring, automated billing)

This feature may soon be coming into AiLiveComplete! Some uses of this In-app billing would be:

  • Unlocking game-levels when user buys a Product
  • Selling digital subscriptions (monthly / recurring)
  • Selling game items like coins, treasures, additional lives, etc
  • Instead of having LITE and PRO version, having only one-version that can be unlocked from LITE to PRO when user buys the PRO product

Here is the output of a sample app that was created using AiLiveComplete:

Reading / Parsing CSV File

App Inventor includes a Storage File component that can be used for reading and writing. One use of this component can be for reading CSV (Comma Separated File) as key value pairs.

Assume you have a a file called myDataFile.csv with contents that includes authors (key) and books (values) like below. Note that in below example, the value can be varible-size tokenized string (string with multiple values):

Hossein,Absolute App Inventor 2|Amazon|Google Play Book|Apple Book Store
Dave Wolber,App Inventor|Google

The code below shows how we can use a TEXT field to get a user-entered key and then search the data-file and return the search data into another TEXT filed. The code below will loop through the tokenized string value and print each token.
