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.
