BeeShell

Java REPL on Android with BeanShell.

Useful for quickly checking some framework API behavior, or calling Java APIs with the permissions of ADB shell.

This is not an officially supported Google product.

Preview

Built-ins

The application Context is available via the context variable in the global namespace.

An Activity instance is also available as activity when running with UI, and references to it in the global namespace will be cleared upon rotation to avoid memory leaks.

Other BeanShell built-ins are also available, though not guaranteed to work, e.g. Swing-based UI built-ins won't work on Android.

Running in ADB shell

Execute the following command in adb shell:

pm_path=`pm path me.zhanghai.android.beeshell` && apk_path=${pm_path#package:} && `dirname $apk_path`/lib/*/libbsh.so

Limitation

BeanShell was written for running on a desktop JVM instead of Android, and as a result class-related Java syntax may be unsupported in this app. Specifically, you cannot define new classes except for anonymous inner classes implementing an existing interface.
