I'm going out on a bit of a limb here asking this but I'm struggling to find any information about this anywhere.
I have built an app with a barcode reader and it works in that it reads the barcode and displays the result. But the result is just the barcode number which we can already see. I want to build it so that it will read the barcode and then give me product information.
I've heard about APIs and how Amazon have one but I can't find out anywhere how to go about this.
Can anyone please point me in the right direction?
Scanning a barcode only gives you the bar code number. The barcode does not inherently contain any data about the product. You need another source for that information. However, once you have the barcode you can just lookup the data from a Google search or some sort of database.

I want get elevation of point offline in my app
I searched a lot but could not find anything for this.How can I do this?
We have a dem file and we may get altitude of point with coordinate (latitude and longitude)
This library seems promising: https://github.com/komoot/batch-dem-reader
This Kotlin app also seems relevant: https://github.com/raynigon/raylevation
If none of the options give you what you need, you'll probably have to implement parsing the file yourself. For that, you can get inspiration from libraries written in other languages (e.g. https://github.com/tkrajina/srtm.py)

You have made facebook clone and whatsapp clone.So you can easily help me.Can you please give me the source code for that or i have made a similar app in android studio and can I convert it to Codename one
The full source code for these applications is available as part of this course https://codenameone.teachable.com/p/build-real-world-full-stack-mobile-apps-in-java
Pulling out a snippet for something like this is nearly impossible as the apps are large and intertwined. There are samples for file upload in the javadocs and a sample image gallery in the kitchen sink demo.

i was searching about some api's for printers but i can't find anything, maybe cause i'm searching that bad.
I wonder if there is any API which i can send some json code (or like that) as that example:
nameFile:"document.pdf",
url:"blabla/documents/document.pdf",
pages:"5"
etc. And the printer "understands" that and start printing.
At all what i'm searching is some code that give's data to printer and these printer starts printing (fck, i need more English classes..)
Thank you all!
Use Javax Print API, and write a utility to convert your own JSON input format to appropriate print api calls.
Refer this for sample program.

I am working on a program which gathers data and stores it in a file. I need to be able to write a program which reads from the created file and plots a scatter/bar/pie graph from it. Does anyone know any Graphing Libraries which I can use to do this? I've seen suggestions for libraries which can graph nodes, vertices etc. but none for common graphs. Help would be appreciated. Thanks
For charts you can use JFreeChart. It is an open sorce java library with a good API.
If you want to draw graphs (trees for example) you can use JGraphX which is also an open source library.

I'm looking for a way to read GS1 DataBar style barcodes from an Android app. Has anyone tried that? Are there any open source barcode scanner projects that I can take advantage of to read GS1 barcodes?
Yes
http://code.google.com/p/zxing/
That will scan GS1 codes, but GS1 isn't a bar code format as much as its a format of the number encoded into the barcode. Processing what those numbers mean is outside zxing's realm.
