How do I set up the latest version of Tesseract in Java?
Step 1 You will need a JNA wrapper to use tesseract in your java project. I have used tess4j for this. Download it from here JNA wrapper for Tesseract Step 2 Now extract the contents of the tess4j archive and found all the jars from lib and dist folder put them all together at new location. Step 3 Go to Eclipse your project and import all the jars into your project. Now you are ready to go ! Ref How to use the Tesseract API (to perform OCR) in your java code
Why would people build native mobile applications for Android/iOS using Java/Objective-C when they could use Xamarin/C# for all platforms if license cost isn't an issue?
Mostly religious reasons which usually narrow thinking ability to understand people - technology in this case and this is where discussion stops. And Church-Of-Apple is special breed (check previous answers) though my 1st box was IIe and today is MBP I was never infected. I can remember my 1st talk about MonoDroid later Mono for Android now in 211-2. The first question by java developer was Can you do F5? (start the app with single keystroke). I could but this exs most native developers and their mindset. Why native? Because the definition for native is needed (this sounds like organic or bio-something hype). When Android developer tells me Xamarin is not native it is easy to prove them wrong with iOS it is slightly more difficult but doable with longer discussion.n nUsual conversation with native Android dev actually this is almost stenogram of last discussion 2 weeks ago (AFB IFB XFB android ios xamarin fanboy respectively XFB - me) XFB So you develop natively with java and Android SDK?nAFB nods or says YesnXFB So what is NDK for?nAFB This is for native++ developmentnSmart ones use c-c++ cos they get that the question is leading them onto thin ice so for them I need more Qs to lower their quardnXFB So why c-c++? What is c++ used for?nNeed to wait for word native then the guard is lowered and hands are So theoretically I can write perfectly legal Android app natively in c++? Why do I need java? So it is easy with Android devs to prove that their definition of native lacks something. This is simply because of technology (VM bytecode etc). With iOS it is a bit different because there is no VM objective-c is superset of c and thus is closer to the metal. But questions like What is more native objective-c or swift? lowers their guard too. Those religious zealots do not understand technology and that programming language is only one parameter in thisplex topic and there is much more to it. In mobile world I personally define native as toolset vendor has chosen to back-up development on their platform so native (so-called-native) is java on Android and objective-c on iOS. It is possible to call java from c++ thus writing Android UI in c++. The same is for iOS with objective-c++. But is it feasible? In most cases not. On the other side try searching for libraries for VoIP (SIP protocol) or OCR for iOS and Android or even better try implementing those. There is no widely used fanboy-native libraries only those written in c++ (SIP -PJSIP OCR - tesseract). Yes there are SIP stack libs written in java or even c# but not for real-life use-case should define which tools can be used. SIP phone implementations on both Android and iOS call native (c++) from native world (objective-c) and this is exactly what Xamarin does but native is c## and native are (c++ libSomething.a or libSomething.a jar) How native or not-native Xamarin is check this one (with update 2 s) made by ex Googler Harry Cheungn 215-3n s@harrycheung s@harrycheung n215-2 n s@harrycheung s@harrycheung For decision making based on code sharing let us share code and reduce cost by reading answers about one use-casen Why did Trello choose Xamarin? question qid 319781 Today even Apple is copying ideas and well proven technologies to enable their multi-language paradigms and multiple hardware platforms and OS-es. Those technologies (il intermediate language bytecode quasi assemblers high level machine code) are used by mono for 15-2 years. Nobody's talking about Apple's biggest developer news Bitcode App Thinning (iOS watchOS) s App Thinning is what Microsoft already does with Windows Phone and Windows Store apps optimizing code in the store and final optimizations for device and OS after installation (download from store) on the device itself. But for the developers that don't want to have cost-reduced apps this might be difficult to accept due to religious beliefs.
