I cannot make the sample (Facedetection) coming with the OpenCV4Android work in Android Studio.
Is there a tutorial for facedetection that would address the users of Android Studio?
Because it does not work to import the Eclipse project that is attached to the library as sample.
I am sure it's because of the NDK dependency, but I cannot seem to get it to work. I installed the NDK, added it to the Path, still no change.
Better yet, is there any way of avoiding the use of the NDK in a facedetection application?
I would appreciate any help in making this work in the Android Studio
I've just uploaded to github a simple sample using OPENCV libraries. Everything is setup already to get it to run really quick. My AndroidStudio is 2.0 Preview 2 (released 5 days ago). Hope isn't too late or at least others may find it useful for quick troubleshooting during installation.
Best.

I am trying to create a LittleKT project in Visual Studio Code. I tried building a Gradle instance of the project but was told that I did not have an Android SDK. I installed the Android SDK Tools and got pretty far. I was unable to use a key emulator that I needed and was wondering if I could completely remove android support for my project.
Any advice pertaining to LittleKT or how to install the needed emulator I need would be greatly appreciated. I did not include many details as to doing that because that is not the point of this question. Plus, there are plenty of discussions pertaining to that issue.
Thanks
This may look like a duplicate question, but all the previous answers were too much confusing for a ameature developer like me. I have never used NDK before and I am working with android studio and windows PC. Previous answers(1,2) and other sources are suggesting to use linux to compile. I couldn't understand what to do. Can anyone guide me through the steps about embeding libvlc in my android app
If you are having trouble with compiling vlc , then you can use the following library , thou it is unofficial , but I worked with it and it worked fine .
Unofficial VLC Android SDK
If you're on Windows 10, you should be able to follow the wiki at https://wiki.videolan.org/AndroidCompile/ using WSL (and google/use the videolan forum for what you don't know).
If you don't want to compile, another way could be to download the apk of the official vlc-android app, unzip it, extract the libs you want (namely libvlcjni.so and probably libjniloader.so) and add it to your project (which means making gradle happy).
vlc-android is a fully opensource app that does exactly what you want to do. Feel free to have a look.
Good luck
I work as an android programmer for just under a year now, and I just started to learn about android game development. The framework I choose to work with is Cocos2d-x.
I have seen guides and tutorials on how to use Cocos2d-x with eclipse, but I'd really like to know if it's possible to be used with Android Studio.
From what I've read, it is now possible to build NDK projects with gradle in Android Studio, which is good news. Nevertheless, I have yet to find any information about C++ programming using Android Studio. Eclipse uses the CDC ( https://www.eclipse.org/cdt/ ) plugin to achieve this.
Is there anything similar to be used with Android Studio? I have found some C/C++ enabling plugins for the IntelliJ Platform, but they were no longer updated.
Has anyone else tried this before? Did it work? Can you provide a step-by-step guide, for a newbie like me, who's dealing with this kind of problems for the first time?
Thank you for you time,

Android Studio currently isn't well set-up for native programming. While the build system supports the NDK, there's no editor support for C++ files (it's not as if it won't work, but the IDE won't give you any editing assistance), and neither is there any debugging support. JetBrains has announced that they're working on new C++ support for IntelliJ, and this is something we're looking at for Android Studio, but it's not on the roadmap yet.
Recent version of cocos2dx v3 (from github for example)
have proj.android-studio project
At this moment I have no success to build it but maybe in future it will be fixed
I just went through the setup for this example code. The project compiles and has a ton of sample code. Scott Barta's answer still stands as an important caveat, but wanted to share the link in case it was useful.
I also found this useful for some NDK background/how-to.
I'm interested in developing an Android App using the Drools (JBoss) expert systems rules based system. It's got a plugin via Eclipse per their tools (v3.2) but I don't exactly know how to integrate Drools Jars into and Android project successfully. There has some talk about the issue (see below) but I don't know if it's been completely resolved. Can anyone enlighten me.

here is another working option, I made a little modification on drools libaries for loading and running DRL rules on android.
check it, hope be helpful:
https://github.com/jorgemfk/dr-drools-android-demo
https://play.google.com/store/apps/details?id=mx.dr.drools
I forked Drools 6 and modified it to use Dex for class generation and it works on Android (using serialized packages compiled on desktop) I put an Android application sample on github
So, do you know how to create android projects? and how to add external jars to your android projects? When you reach that stage, this post may help. It talks about jbpm5 running in android but it depends on drools so it should be the same.

I'm having a hell of a time importing OpenCV into my Android project. I've already tried this tutorial:
http://opencv.itseez.com/doc/tutorials/introduction/android_binary_package/android_binary_package.html
and it did not work because Eclipse would not recognize the existing projects in the directory. So after much searching I came across this trunk:
https://code.ros.org/svn/opencv/trunk/opencv/
and was able to import it into my workspace in Eclipse. Eclipse now recognizes the sample projects, but now the problem is that there are no OpenCV library files. So all the calls to import different classes result in errors. Shouldn't there be a opencv.jar somewhere? I've seen various posts that mention having to build the library but unfortunately I don't have the slightest clue how to do that. I need something with step by step instructions. I'm running Windows 7 64-bit.
Thanks!
You should download the latest OpenCV 4 Android here:
http://opencv.org/downloads.html
And read these tutorials to get you started (in this order roughly):
Introduction into Android Development
OpenCV4Android SDK
Android Development with OpenCV
OpenCV4Android Reference
If you want to use OPEN CV in your android apps, for example if you need to read some strings from an image in your android and you are new in using OPEN CV. Then download the pre-built OpenCV library for Android from here:
http://sourceforge.net/projects/opencvlibrary/files/opencv-android/2.3/
After downloading, import OpenCV-2.3.1 into Eclipse using File-->Import...-->General-->Existing Project Into Workspace.
In your project's properties, Under Android, add the OpenCV2.3.1 library (press Add.. on the right and select OpenCV2.3.1).
Good luck!
You might want to take a look at this project: https://github.com/billmccord/OpenCV-Android
I was able to run opencv applications on my android phone with the help of this port.
installed the Win-superpack?
I recommend getting the latest .tar, extract and use it. Worked for me.
I posted about this on a duplicate question. Make sure you have the android NDK installed! Or, consider using JavaCV instead. It is much easier to install.
