currently I'm working on an app in which I have a small IDE. Now I need code-completion and syntax-highlighting. How can I realize something?
Does somebody has any idea? My first approach was an XML file from which the syntax is matched. But this would be very costly.
A corresponding API I have not found. Only "Programmr" provides an API for Web. But nor for Android / Java.

Edit: It's not a duplicate of What code highlighting libs are there for Java?. There are Libs for Highlighing Java in other langueages. I need a lib for Highlighing Java-Code in an self written IDE (written with Java for Android)

currently I am using Sphinx4 in a java desktop application to just to match some speech/words against the xxx.gram file. I have not installed sphinx in my system rather I'm just using sphinx4.jar in my project's classpath. And its working fine till now.
Now, I want to use it with Spanish, Portuguese, and Chinese languages. how could I do that? I don't want to install Sphinx. Is there any .jar file or light weighted code or services (even if other than sphinx) available for the same?
You can download Spanish model here:
http://sourceforge.net/projects/cmusphinx/files/Acoustic%20and%20Language%20Models/Spanish%20Voxforge/voxforge-es-0.1.1.tar.gz/download
Portuguese and Chinese are not supported. If you need them you can build models from your audio, see for details
http://cmusphinx.sourceforge.net/wiki/tutorialam
To make data collection easier you can use audiobooks.
I'm interested in writing Java to automate the creation of 3D STEP files (CAD format).
There seems to be something for C++ (https://github.com/stepcode/stepcode). There seem to be Java implementations of 3D CAD software (http://brlcad.org/).
However, I don't see an API / Package / Class Library anywhere to build STEP files using Java.
Ideas?
JSDAI is a java API for STEP files and is licensed AGPL.

BIMserver and its friends in Open Source BIM](https://github.com/opensourceBIM) can easily handle this problem without writing a single line of code.
I'm trying to read pdf files in my android application. I don't want to use the default pdf reader and simply open a new intent because I need my own GUI, and want to use the first page as a cover. Therefore I need to make my own pdf reader. I did some research and came across muPDF and Android PDF Viewer Library.
I tried to follow tutorial to implement Android PDF Viewer Library, from the github description. But the problem is that it loads pdf file forever. Do I need to do something else than just the steps in the description?
I can't find any tutorials for the muPDF library, are there any? How to implement it?
If there is no useful answer for the previous two questions, are there any good pdf library out there with tutorials and good documentation?
Thank you, hopefully, I will be able to solve my problem
MuPDF is a very good library, you can definitely use it. If you need a complete example of Android app using MuPDF, I suggest you to take a look at this customizable magazine app on Github.
first of all, if you want to use MUPDF inside an existing android app project you can follow the guide you find at this link (all credits go to the author, I didn't write this).
I am trying as well to integrate a very simple PDF reading/printing solution inside my app and i am struggling to strip down/simplify the MuPdf application demo you get by following that guide. I already managed (somehow) to remove annotation and file-picking features, but i would really need some help as well to get all the job done. There's really a lot of stuff and absolutely no documentation about this. I am simply trying to read the code and figure out what is needed and what is not, removing features one by one and being driven by the errors you get in catlog.
Also, as we both (if I understood correctly your needs) need just the PDF rendering features, would be great if someone points out how to (if possible) disable some of the unnecessary features built in the MuPDF library when building it from source (as DjVu support, just as an example).
Hope this helps, even if it is not a real answer to your question.
This is how I succeeded in building a MuPDF lib on windows with Cygwin, android-ndk
Download MuPDF 1.3 Source from https://code.google.com/p/mupdf/downloads/list
unzip to folder c:/mupdf-1.3-source
Install Cygwin:
Download and run Run setup-x86.exe from http://cygwin.com/install.html
when installing cygwin, make sure you selected make packages and C++ compilers
Make generate. open cygwin terminal, run
cd /cygdrive/
cd c/mupdf-1.3-source
make generate
Install android-ndk:
download android-ndk-r9d-windows-x86.zip and unzip it to
c:/android-ndk-r9d
Build mupdf lib: on windows cmd console:
preparation:
cd c:/mupdf-1.3-source/platform/android
copy local.properties.sample local.properties
edit local.properties, uncomment
#sdk.dir=C:\\Program Files (x86)\\Android\\android-sdk
and change to
sdk.dir=REAL andforid-sdk Folder
build:
while still on c:/mupdf-1.3-source/platform/android, run:
/android-ndk-r9d/ndk-build
Upon the completion of the build, a folder named libs will be created under
c:/mupdf-1.3-source/platform/android
Create android apk.
Open eclipse, create a new android project from existing code, browse to c:/mupdf-1.3-source/platform/android, now you can create a mupdf apk.
Starting with Android 5.0 you can also use Android's internal PDF renderer and for manipulating PDF you can always use iTextg - just some alternatives for the future.
This SO answer lists some steps on how to rip essential pieces from the MuPDF Java sample app to one's own.
Preferably, I'd like to have a "ready to use" Java library I could attach to as a dependency. Is JNI preventing this or is it simply that no-one's gotten up to doing one?
Well, jmupdf is there (mentioned in this duplicate) but that lists Windows and Linux (not specifically Android) as the tested platforms. It seems desktop and dead to me (no changes in 12 months). At least compared to the vibrance of MuPDF itself.
I am developing GWT API. I am trying to find a way for obfuscation to my java code(API). But, GWT works only with source code. But I dont want my algorithms does not understand from developers who use my GWT API. Is there any way to obfuscate my java codes. Another isue is licencing. Is there any way, developing client licence for GWT.
The GWT Compiler only works on source code because we need the extra on information that is inside java files compared to class files.
So if you want to develop an API for GWT you can only do this by shipping open code to your customers.
I'm developing a project for doing Content Based Image Retrieval where front end will be in java.
The main issue is about choosing tool for performing image processing. Since Matlab provides a lot of functionality for doing CBIR. But the main problem about using Matlab is that you need to have Matlab installed on every computer using the application.
Is there any other way in which I can do my project (Using other tools or driver) so that my application will run without using any other tools ???
Or can I develop entire application in Matlab only and deploy it as a standalone application ???
Thank you..
There are plenty of image processing libraries, for example for Java: ImageJ, there is also one by the Apache Commons project. If you need higher-level computer vision libraries there is OpenCV for C++ that also has bindings for Java, for example.
You can also develop the entire application in Matlab, but to deploy a stand alone application requires this requires licensing Mathworks Builder NE (which can be expensive). Matlab is very good for research and prototyping purposes.
There are other alternatives that are amenable to quick prototyping for example Python and PIL.
I think the bottom line is that there are plenty of options.
Java image utilities library: A Java library for loading, editing, analyzing and saving pixel image files.
It supports various file formats.
Provides demo applications for the command line. It has AWT GUI toolkit too.
Matlab is an excellent tool for prototyping as already pointed out by carlosdc. Matlab offers limited options with regard to UI programming. GUIDE is ok for small projects, but hinders more than it helps on bigger ones.
With MATLAB Builder JA you're able to compile your Matlab code into Java classes.
With regard to plotting time series in real time, libraries like JFreeChart are way slower.
I think OpenCV is one of the best libraries out there for image processing but Java Advanced Imaging is also quite good but doesn't has as much features and examples. Color similarity would be simple in JAI but shape probably would involve more code.
If you choose to use OpenCV I think you have at least two possible binding implementations for Java. The one my group uses is this one. It has some Processing dependencies.
Regardless of what library you choose be prepared for some frustration. Matlab users are used to all the nice features it provides and when they have to port their code to other languages end having to write a lot more code.
Well, after a long search finally I've found the way to deploy Matlab code along with java that too standalone application..
The steps are simple::--
1. Go and get Javabuilder.jar file located at location::
Matlab\toolbox\javabuilder\jar\javabuilder.jar
Next type deploytool in Matlabs command line...
deploytool window will open now create a new java project.
Select Matlab files that you want to use.
The deploytool will now convert the .m file to .jar file.
Now use both of the above mentioned jar files and develop your java compatible matlab code
and thats the way you can create the standalone application of matlab..
