# ActivityStarter

A component that can launch an activity using the `StartActivity` method.

Activities that can be launched include:

* Starting another AppyBuilder app. To do so, first find out the *class* of the other application by downloading the source code and using a file explorer or unzip utility to find a file named "youngandroidproject/project.properties".

  The first line of the file will start with "main=" and be followed by the class name; for example, `main=com.appybuilder.pmathijssen.MaterialDesignColorPalette.Screen1`.

  To make your `ActivityStarter` launch this application, set the following properties:

  * `ActivityPackage` to the class name, dropping the last component (for example, `com.gmail.Bitdiddle.Ben.HelloPurr`)
  * `ActivityClass` to the entire class name (for example, `com.gmail.Bitdiddle.Ben.HelloPurr.Screen1`)
* Starting the camera application by setting the following properties:
  * `Action`: `android.intent.action.MAIN`
  * `ActivityPackage`: `com.android.camera`
  * `ActivityClass`: `com.android.camera.Camera`
* Performing web search. Assuming the term you want to search for is "vampire" (feel free to substitute your own choice), set the properties to:
  * `Action`: `android.intent.action.WEB_SEARCH`
  * `ExtraKey`: query
  * `ExtraValue`: vampire
  * `ActivityPackage`: `com.google.android.providers.enhancedgooglesearch`
  * `ActivityClass`: `com.google.android.providers.enhancedgooglesearch.Launcher`
* Opening a browser to a specified web page. Assuming the page you want to go to is "[www.facebook.com](http://www.facebook.com)" (feel free to substitute your own choice), set the properties to:
  * `Action`: `android.intent.action.VIEW`
  * `DataUri`: `http://www.facebook.com`
