Android compilation tool ant

AntIs a Java-based build tool, similar to make in (UNIX) C. Unlike the extension mode based on shell commands, ant extends with Java classes, you do not have to write shell commands. Ant is a process script engine used to automatically call programs to compile, package, and test projects. In addition to Java, the script format is based on XML (default: Build. XML), which is easier to maintain than make scripts.
