Trying to learn about how to verify an image which is stored inside android app ( somewhere in Asset folder ) to a card which already has some logo (check if both the logo are identical) using camera .
Was reading about Open CV but it is all in C++ . Need Java code.
Any rough idea or document or link or tutorial anything will be appreciated.
Why don't you make use of JavaCV, it's a port of OpenCV.

Is we have a screen capture token on android , what information can we get from that file about the source device ( we can know the screen resolution for exemple , but what else ? ) .
as I know, the basic screenshot have the default jpg metadata, which contain just basic date and maybe the android version of the device.
but if you want to look into the metadata of a photo you can try to look for EXIF tool to get it.
I have a doc/ppt/xls file located in my sd card. I want to open it without any third party app (i.e within my app itself) using webview. Though I am able to open documents by embedding it in google docs url like -
http://docs.google.com/gview?embedded=true&url=[filelinkHere]
But how to open a file located in internal or external storage in webview ?
Also, Suggest me any third party ALL-IN-ONE library for android to view all types of documents. I have tried ASPOS but it has few unresolved bugs and APACHE-POI is difficult to use.
I had the same issue few days ago .
i found Android PdfViewer best to view PDF files and Android PdfMyXml best to create pdf files in android.
For working with Word and Excel as a most reliable answer I suggest you to take a look at OliveDocLibrary .
If your documents are in cloud so there is an alternative way to display docx,pptx,pdf and such formats with a combination of Webview and googleDoc.
You might find other possible solutions in server-side machines or maybe a creative way!
Hope it help
You can integrate some library project to your project with which you can open the pdf file inside your app.
Reference :
https://github.com/tekinarslan/AndroidPdfViewer

In my project I have to load the contents of a PDF located in the assets folder onto a WebView.Can It be achieved directly just by reading the contents onto a WebView.. I googled a lot and I found that i need to use third party PDF readers to achieve the same?
If so, Plz give me the links of the source of the PDF reader of GITHUB. Am not able to find it..
If you load pdf inside the webview, unicode text type or images wont be visible. So you want
to go for OCR tool.
Use set of libraries and sdk

mupdf is the best library in terms of performance and all i have found till now, you can also use it in your application.
But it needs knowledge of ndk.

I want to create an PDF that contains images. I have used the iText library to create the text portion of the PDF, but have been unable to find any way to add images.
Separately, I would also like to upload this to dropbox after creating the PDF.
Does anybody have any suggestions of where to look?
You can try ImageMagick: http://www.imagemagick.org/script/index.php.
It is a c/c++ library and is required to use as JNI in android. You can use JMagick as wrapper for java
