AIDE vs DrJava

AIDE is an integrated development environment for creating Android apps and other mobile projects directly on an Android device. It supports Java, C/C++, HTML5, CSS, and JavaScript, with Android and PhoneGap/Cordova listed as targets. The editor includes code completion, error checking, refactoring, and code navigation. A mobile Android SDK is included, so the maker says a separate SDK installation is unnecessary for Android app development. AIDE also supports Android NDK work with C/C++ on Arm devices, provides Git and Dropbox support, and opens Eclipse projects plus basic Android Studio projects using the default structure. The full Gradle build system is not supported. Interactive lessons teach programming step by step while letting learners build apps. A visual UI designer and app packaging are included. AIDE is freemium: Android Edition is free; UI Designer costs 2.99 USD once, while Premium Key and PhoneGap Edition cost 9.99 USD once. Final prices depend on country.

DrJava is a free, open-source development environment for writing Java programs, designed primarily for students. Its intelligent editor supports coding, while the Interactions pane lets users evaluate Java code interactively. The environment includes JUnit testing, a source-level debugger and Javadoc generation for source files. It runs on Windows, macOS and Linux under a standard BSD open-source license. The current beta is compatible with Java 8, identified by the project page as the only supported version of traditional Java. That beta is distributed only as a JAR, which the page says is intended to reduce cross-platform compatibility issues. The Eclipse plugin is described as very old and compatible only with Eclipse versions from the same era. The Linux FAQ reports an incompatibility with the Compiz window manager and recommends disabling Compiz if it occurs. Bug reports and feature requests require a SourceForge account login. The Free plan costs nothing, with no free trial listed.
