I'm new to Android and OpenCV, and I try to follow this simple tutorial. I got stuck at implementation of CvViewFrameListener2 interface:
Defines that your activity implements CvViewFrameListener2 interface and fix activity related errors by defining missed methods.
Eclipse shows an error, that the CvFrameListener2 cannot be resolved to a type. It seems like this interface doesn't exist in the library.
I load OpenCV4Android version 2.4.5. Can anybody help me?
I m sure this is late. But I faced this problem too, here my workaround
make sure you have imported the openCV sdk as a library project and linked to your project.
Hope this help
also I used this project from github for face recognition face recognition
and this link to download OpenCV 2.4.6 android sdk
http://sourceforge.net/projects/opencvlibrary/files/opencv-android/2.4.6/OpenCV-2.4.6-android-sdk-r2.zip/download

I find java sdk https://github.com/liqpay/sdk-java for integration liqpay with maven, but my project uses gradle. So I can't use this. How can I solve this problem?
It looks like you posted link to java library, not android version. I think that this version should be used on server side, not client (android) side.
Here is link to right github project:
https://github.com/liqpay/sdk-aos
Here is additional link with description of library that was described in ugly way:

Anyway, maybe you finished your task with LiqPay on android? If so, please, post complete solution of this task
Im building a simple game with Xamarin/Cocossharp in a Shared Project.
I added some physics with Box2D and everything works well on WP8.1.
I import Box2D and i access to the methods and class provided without problem on Windows Phone, but when i try to compile it for Android it says that the type or namespace "Box2D" could not be found. Intellisense doesn't shows any error...
error output
I'm new to game dev and also to VS2015 so it may be something simple but i dont understand what I'm missing here.
Thanks in advance
After struggling around with this i managed to fix this:
As pointed out from Sven-Michael in his answer the solution was to install:
CocosSharp.PCL.Shared
from NuGet. In my case was only necessary to add the reference to the Box2D.DLL file contained into the package.
The reason why it was not working for me it's probably that because of trying to solve this problem I've messed up whit my solution and caused other problems. So I created a new Project from skratch and I've imported my source code again.
Ensure that you have installed CocosSharp.PCL.Shared to your Android project.
E.g. via PM-Comsole:
Install-Package CocosSharp.PCL.Shared
But it can be installed via NuGet, too. This will add box2d and some other dependencies automatically.
I'm writing an android app which uses offline maps.For this I'm using osmdroid, I've come across this link which refers to an update of osmdroid the osmbonuspack. Can you point me at some tutorials and sample codes besides those provided by the openstreetsmap so that I can get started?
Here is working link https://github.com/MKergall/osmbonuspack.
Please let me know if links are dead.
This implementation (app:Gradle) worked for me in Android Studio using SDK 29:
implementation 'com.github.MKergall.osmbonuspack:OSMBonusPack:v5.7'
You can find this MKergall's Maven repository
NOTE: you will have to comment out your previous osmdroid (mine was 4.3) jar implementation, because methods are duplicated.
Hello I am trying to learn a little bit of facebook-sdk for android but no luck.
I will post some screenshots so you easy understand what is my problem.
1st step I am adding the SDk to my project
2nd step I import Classes but i get an error
And when I am going back to android tab I see this
Really need help. I tried Many times to follow the steps from FB Guide in case I forgot something but didnt helped... Thank you in Advanced.(I am new to this hope you will understand)
Your "Jar mismatch" problem comes into picture because of the Facebook SDK itself has android support v4 jar as well as your project also same jar file.
To solve this problem..
Go to your project's properties -> Java Build Path -> Order and Export :
Now remove the Tick-Mark from Android Private Libraries.
make sure that you had already used facebook SDK's private library (tick-marked)
And then after clean your work space..
It will always help me..
Hope this will help you to solve your problem.
I have a problem while running the examples from andengine. The error I'm getting is at this line:
System.loadLibrary( "andenginephysicsbox2dextension" );
Couldn't load andenginephysics2dextension. Find library returned null. I noticed other people kept having this problem but no solution was proposed.
Any help is welcomed! Thanks.
looks like you missed to copy the native libraries. AndEngine is now hosted on github and it is in perfectly active development! ( https://github.com/nicolasgramlich/AndEngine ) more info on what changed in the new GLES2 version here: http://www.andengine.org/forums/announces/andengine-gles2-pre-release-on-december-23rd-t6097.html#p26851
Using AndEngine as a library project is recommended and this will automatically 'copy' the native libraries to your project.
Best Regards,
Nicolas
The error you are getting is because you have to build the Box2D extension yourself. I think there is tutorial how to do it. However i stoped there and downloaded the demos from market. Then eventually switched to libGDX.
Check out this tutorial: http://www.youtube.com/playlist?list=PL6131C7A9DDCF959A
The new way of using andEngine is to include the git repos as libraries (without making any jars)
