# Android Utility Classes

J2ObjC's `jre_emul` library includes a few utility classes from the Android API. These classes do not implement any core Android functionality, but are generally useful for cross-platform Java code. Also included are the Android [JSON](https://developer.android.com/reference/org/json/package-summary.html) and the [XML Pull Parsing](https://developer.android.com/reference/org/xmlpull/v1/package-summary.html) libraries.
