title: How to block ads in a 3rd party app: Android
body: <p>I am building an operating system for children; the app is a launcher. From this app, children are allowed to use 3rd party apps, except requirements are that the ads should be blocked because some ads are inappropriate for our 3-5 year old targeted audience. Without actually owning these 3rd party apps, I have not thought of too many options for accomplishing this. The only thing I could think of is to turn off network connection while using these apps. Without a network connection, these 3rd party apps will not be able to display their ads. However, I see a huge drawback to this solution. Many (dare I say most) apps are meant to work with an active network connection, and without one these apps do not function.</p>
  
  <p>Can you think of a better way of doing this? Is there a library that exists that I do not know of, or method for doing this that you can enlighten me on?</p>
  
  <p>Thank you in advance.</p>
