Question

So i’m trying to implement that into my app, however the problem is that it doesn’t work as a solo application so it crush evrytime i start it. I do evry thing as in followed tutorial http://damianflannery.wordpress.com/2011/06/13/integrate-zxing-barcode-scanner-into-your-android-app-natively-using-eclipse/ however, it somehow doesn’t work. So i tryied to start the captureActivity as application rather than library, and it crashes on start when it tries to do that:

 private static final Set<ResultMetadataType> DISPLAYABLE_METADATA_TYPES =
  EnumSet.of(ResultMetadataType.ISSUE_NUMBER,
             ResultMetadataType.SUGGESTED_PRICE,
             ResultMetadataType.ERROR_CORRECTION_LEVEL,
             ResultMetadataType.POSSIBLE_COUNTRY);

That leads to the problem that i didn’t compile core.jar correctly. However i can’t see where would i do a mistake. I run ant -f in core directory, and it gives me core.jar. Any ideas what could i do?

Now i downloaded the core from here http://mvnrepository.com/artifact/com.google.zxing/core/2.0 and used it and steal same mistake so it must be something else…

Answer 1

Go to Properties -> Java Build Path -> “Order and Export”

Then order the core.jar to the first position and select it!

you must clean your project after your operation. Project -> clean

That solves the problem. I hope it saves somebody’s time.
