Chess for Android is a chess application for the Android platform that supports the Universal Chess Interface (UCI) and Chess Engine Communication Protocol (often simply called the XBoard or WinBoard protocol). This feature allows replacing the built-in Java chess engine with more powerful third party engines. Users can either play an imported engine directly, use infinite analysis to study games, or even run tournaments between engines.
Applications that target API level 29 and run on Android 10 can no longer install engines from SD card due to new security-related restrictions on W^X violations. In such cases, only properly packaged engine binaries (OEX or Chessbase) can be imported by other chess applications.
