Welcome to the JUMP platform libary for Android. This library is available open-source under a Berkeley license, as found in the LICENSE file.

Getting Started: Docs/

Phonegap Plugin:

Report bugs or ask questions:

Old git repo: New git repo: (Both are exactly the same, for now.)

Updating from 3.x to 4.0:

  • 4.0 adds and focuses on Capture support, renames the library project / IDE metadata to "Jump"
  • See the developers integration guide,
  • There's a new initializer signature

Updating from 2.x to 3.0:

  • See the documentation on

Updating from 1.x to 2.0:

  • Replace the activity declarations in your AndroidManifest.xml with fresh copies from JREngage/AndroidManifest.xml
  • Update your Android target to Android 13 / Honeycomb 3.2 (still deployable to Android 4+ / Donut / 1.6) (Alternately, remove the "screenSize" configuration change handler from the "configChanges" portion of each JREngage Activity declaration in your AndroidManifest.xml and then target your app at lower versions of Android.)
  • Ensure that the JREngage/libs/android-support-v4.jar is added to your IDE's project (ant builds work without updating)
  • Ensure that the jackson-core-lgpl-1.6.4.jar and jackson-mapper-lgpl-1.6.4.jar libraries are removed from your IDE's project.

Using tablet support:

  • Tablet support works in two modes, either embedded as a UI Fragment or as a modal dialog.
  • To show a modal dialog simply continue to call JREngage#showAuthenticationDialog() or JREngage#showSocialPublishingDialog(...)
  • To start a Fragment in a specific container call JREngage#showSocialPublishingFragment(...)
  • Or, if you wish to manage the Fragment yourself (e.g. to add it to the back stack), use JREngage#createSocialPublishingFragment(...)
  • Embedded mode requires a host activity sub-classed from, is incompatible.
