  2. Start Android Studio and open project from Vision > Android > Sample folder.

  3. In Android Studio -> "Project" panel -> "Android" view, open file "app/res/values/strings.xml", and find the keys subscription_key and subscription_apiroot. Replace the placeholder values with those obtained in step 1 above. If you cannot find the file "strings.xml", it is in folder "Sample\app\src\main\res\values\string.xml".

  4. In Android Studio, select menu "Build > Make Project" to build the sample, and "Run" to launch this sample app.
