ZBar Android SDK
================
ZBar Bar Code Reader is an open source software suite for reading bar
codes from various sources, such as video streams, image files and raw
intensity sensors. It supports EAN-13/UPC-A, UPC-E, EAN-8, Code 128,
Code 93, Code 39, Codabar, Interleaved 2 of 5, QR Code and
DataBar. These are the JNI wrappers for developing the library on
Android platform.
Check the ZBar home page for the latest release, mailing lists, etc.

Installation
------------
After downloading the ZBar-Android-Lib-<version>.zip file, you need to
unzip the file and add it to your Android project. Unzip the file
using your favorite method (ie: command-line, finder, windows
explorer...)
Follow one of the two options.
Option 1 - via command line
cd <android project>
cp -r ZBar-Android-SDK-<version>/libs .
Option 2 - via Eclipse
Right click on Android Project
Select "Import" -> "File System"
Select "Browse" (next to "From directory File" and select the
ZBar-Android-SDK-<version>/libs directory and click "Open".
Click the check box next to "libs" and the "Options" "Create top-level folder"
check box (below).
Then click "Finish".
You should then see a "libs" folder under your project.
Building
--------
Via Eclipse
You have to add the zbar.jar file to your build path
1) select zbar.jar under libs
2) right-click, select "Build Path" -> "Add to Build Path"
Via command-line
You are all set; ant will automatically find jar files under the "libs"
subdirectory.
Documentation
-------------
TDB
Examples
--------
You should be able to open and build the examples directly from the
unzipped directory. You will need to run the android tools to setup
the local.properties file which sets sdk.dir.
1) cd <unzip dir>/examples/CameraTest
2) android update project --path .
3) ant debug install
If you have problems with this, please create a new Android project
and copy the necessary files from the examples.
examples/CameraTest is a simple demonstration of how to integrate the
ZBar image scanner with the camera.
Manually building ZBar JNI library
----------------------------------
First download and unzip the iconv library source from
http://www.gnu.org/software/libiconv/
Then kick off the build from the ZBar android directory. You will
need to run the android tools to setup the local.properties file which
setups sdk.dir.
1) cd <zbar project>/android
2) android update project --path .
3) ant -Dndk.dir=<NDK path> -Diconv.src=<iconv library src> zbar-all
This will rebuild all source files, create zbar.jar and
ZBarAndroidSDK.zip file (which bundles the jar and shared
libraries). From here, you can follow the steps for "Integrating ZBar
JNI library in Android project".
To clean run:
ant -Dndk.dir=<NDK path> zbar-clean
See build-ndk.xml for additional target options.
