Most resources that tell you how to install OpenCV for Android seem to assume that you are starting from scratch. (see: http://docs.opencv.org/doc/tutorials/introduction/android_binary_package/dev_with_OCV_on_Android.html) I have a project that I have been working on for the last couple of weeks. Now I want to add OpenCv libraries. Is this possible?
Well, the tutorial you linked has everything you need.
Read through Hello OpenCV Sample part, but start from step 5.
5 . Import OpenCV library to the current workspace and build it.
6 . Add it as library in the project properties of YOUR project.
Then import packages in your MainActivity as necessary, make sure to add permissions and features in the manifest if you want to use camera.
And most importantly, add OpenCV library initialization in you MainActivity. Just as the tutorial describes.
Update your question if you run into any particular problems.
Hope that helps!

I have two android projects with me. I need to add the first project as a library to the other project.
Now, when I am trying to open the activity of library project from the other application on a button click, i am getting Android.content.ActivityNotFoundException at run time.
Can anyone suggest some pointer on this.
you need to check that you added the new activity to the manifest.xml file
if you are Using ADT(Android Developer Tool).
Thanks for the concern. This issue is resolved for me. Sorry for the late reply. I have created the second application as library project, which is included in first android project.
The point, which fixed the issue is: add the contents of the manifest.xml of library project in main project and the reference provided is the full path for the activity(including package name).
Hi there I am just newer in android development and I am trying to build my first app and I do will until now.
but I need to use ViewPagerIndicator so I do my search and I've found JakeWharton-Android-ViewPagerIndicator also I am using inellij IDE
but the problem that when I want to add this library into my project I can't find the jar file and I don't know if the error from my side or what please any help.
regards
You will need to create a new module with the library sources and add it as a dependency to your main module. This answer has detailed steps you can follow. Just replace the library used with ViewPagerIndicator.
Ok, i've wasted an hour trying to figure it out, even though it's something really simple.
I've downloaded some code from github. I'd like to use this in my android application. How do I go about adding it? It's not a jar file, and i tried drag dropping it and linking the files, and it didn't work. Importing and refreshing / cleaning the project didn't work.
I'm not sure where I'm going wrong. Any help is greatly appreciated!
If this is a project you want to import in eclipse, right click on eclipse left pane (the project list), import, android project from files, select the repository folder.
If this is a library you want to use in you app, there is another step : go to the properties of your project, android tab and in the library section click on add, then select the library project.
By design, android code that contains layout resources (for example ActionBar Sherlock) can not be embedded in a jar. So you have to use it as a library project. It is very convenient though, since it allows you to look at or modify the library code very quickly.
You may also need to let Eclipse know that your library project is a library and not an app. To do so, in the same Properties/Android screen you just have to check the "is a library" checkbox.
Reference on that topic : official documentation
In Eclipse:
File->New->Other->"Android Project from exiting Code"
I was asked to make a project work in Android and I am a complete noob in this aspect and, well... things are not working...
I have created a little code in Java which uses libraries - this code works perfectly. I am now trying to make this code work on Android but I have problems...
It seems I cannot use any element from the libraries I imported to my Android project. The project loads on the phone perfectly fine when no instance of the library is created, but when I make use of the library the app crashed and I get errors.

Here is what the project package looks like

The part with the arrow is what I think makes the program crashed. When I remove this line, everything works fine.
I checked online about problems with Android and external libraries but I could not understand everything... Could you help me pinpoint exactly what is wrong and how to solve this?
Thanks!
I got this issue when I first started android development.
Key to this is to the external library seems to require them being another android project itself, instead of java project. After creating this android project, right click on the "external project" and choose properties. Under Android Tab, there should be something to check to denote that it is a library instead of application. After doing this, the linking is quite similar to how we link normal java projects to external java library
If you are using eclipse, than just create a "libs" folder in project root and drop your external libraries there.
Alternatively you Right-click on the jar file > build path > add to build path
I want use ActionBar for my application but i found it can't use for android < 3.0.
I found this https://github.com/johannilsson/android-actionbar to solved my problem but I get error at
import com.markupartist.android.widget.ActionBar;
import com.markupartist.android.widget.ActionBar.Action;
import com.markupartist.android.widget.ActionBar.IntentAction;
Give ActionBarSherlock a try. I use it for one of my projects and after some reading of the docs and the samples it just worked. The samples are easy and straight forward, you should be able to extract what you need from them.
To see what it's able of just download the sample app from the market: Sample App (requires at least Android 1.6)
You should add the code to a library, and add the library to your project.
To do this in Eclipse create a new project, using the same package name as the github project (so com.markupartist.android.widget). In the properties select the project to be a library under the Java Build Path tab. Then, in your project, go to its properties, and select the library.
I think your including files are missing (JAR libs) , Click on error icon and then select fix project setup.
I spent around 10 hours trying to fix this problem. All the above ans does not work. Actually what is missing is android support library. To fix this, right click on project, >Android Tool> Add Support Library. Hope this save alot of time for other who came across this. just add support library both on your ActionBar library and the current project.
