/** The IAP system for Android supporting the following stores:
 * <ul>
 * <li>via gdx-pay-android-openiab.jar: Google Play
 * <li>via gdx-pay-android-openiab.jar: Amazon
 * <li>via gdx-pay-android-openiab.jar: Samsung Apps
 * <li>via gdx-pay-android-openiab.jar: Nokia
 * <li>via gdx-pay-android-openiab.jar: Open Store
 * <li>via gdx-pay-android-openiab.jar: SlideME
 * <li>via gdx-pay-android-openiab.jar: Aptoide
 * <li>via gdx-pay-android-ouya.jar: Ouya
 * </ul>
 * <p>
 * To integrate into your Android project do the following:
 * <ul>
 * <li>1. add the jar-files to your project's lib directory as follows (IAP will work automatically once the files are present):
 * <ul>
 * <li>gdx-pay.jar: This goes into your "core"/lib project.
 * <li>gdx-pay-android.jar: ALWAYS include within your Android/lib directory to support the IAP systems below!
 * <li>gdx-pay-android-openiab.jar: into Android/lib if you want to support the stores listed from above mentioning OpenIAB.
 * <li>gdx-pay-android-ouya.jar: into Android/lib if you want to support OUYA.
 * </ul>
 * <li>2. AndroidManifest.xml: add the required permissions (i.e. "uses-permission...").
 * <li>3. proguard.cfg: add the required proguard settings for each store you want to support (see: TODO).
 * </ul>
 * Please note that no code changes for Android are necessary. As soon as you place the jar files everything will work out of the
 * box (instantiated via reflection).
