将Java包从Matlab deploytool导入Android Studio App

Question

I managed to create a java package from a Matlab function (for image processing) using deploytool. I tested it in Eclipse and it runs perfectly. The problem is that I want to use this Matlab function for an Android Studio project and I can´t find any way to make it work.

As you may know, when you use Matlab´s deploytool for java packages it generates three folders: "for_redistribution" which contains an .exe file (MyAppInstaller_web.exe), "for_redistribution_files_only" that contains the .jar and documentation, and "for_testing" which contains pretty much the same, the .jar file, documentation and java classes

My question is: is it possible to use this in an Android App? And if so, how? And are there any other options (other than using openCV instead of a Matlab function) to make it work?

Thank you in advance

Answer 1

Java components that are generated from MATLAB code using deploytool (or using other functionality from MATLAB deployment products such as MATLAB Compiler, MATLAB Builder etc.) depend on the MATLAB Compiler Runtime (MCR).

The MCR has much too large a footprint to run on an Android device, and it's really not possible to deploy MATLAB Code to Android in this way.

You have two main options:

1. Use the add-on product MATLAB Coder to convert your MATLAB code to C. This C code does not (unlike the deployment products) depend on the MCR, and be compiled and incorporated into your Android app like other C code.
2. Deploy your java component as a web service, and have your Android app communicate with it remotely.
