check out zxing from Svn reository
then in zxing folder i found several folders ,i don't know which one is used to integrate zxing library in android app,here i am placing the zxing folder after checkout.
Checkout Integrating the ZXing library directly into my Android application question and answers on Embed Zxing library without using Barcode Scanner app question.
I'm quoting the answer of Sean Owen, one of the author's of Zxing library from this answer:
core.jar
from core/
and put it in your Android lib/
folder to include the core
decoder in your app. You do not want to include javase. You can look to the code in
android/
as it is the source to Barcode Scanner, but as the authors we'd suggest you
not just copy and paste it."Hope this helps.
