I'm using Eclipse for build an Android project. when I try to open bellow item :
file --> new --> Android Application Project
Then when the project is built a series errors displayed :
I am a beginner in this regard and thank you for your help.
Open AppCompactv7 and add as library on your project
The problem is with your appcompat_v7 project. Delete the existing project one in the workspace and re-import it from
\sdk\extras\android\support\v7\appcompat
After that try cleaning the project.
Project -> select Clean -> select the project.
1 - Make sure library project(appcompat_v7) is open & is proper referenced (added as library) in your application project.To do this follow this steps: right click in your project -> "Properties - Android - Add"
2 - Delete android-support-v4.jar from your project's libs folder(if jar is present).
3 - Appcompat_v7 must have android-support-v4.jar & android-support-v7-appcompat.jar inside it's libs folder. (If jars are not present copy them from /sdk/extras/android/support/v7/appcompat/libs folder of your installed android sdk location)
4- Check whether ActionBarActivity is properly imported. (In your case this is right)
import android.support.v7.app.ActionBarActivity;
Here is a good example of how to create a project in Eclipse using v7 Support Library
Finally because you are a beginner I'll recommend you to use Android Studio as it is the official environment for developing for Android. Configuring the SDK can be quite a pain in Eclipse. You can also take advantage of the Gradle dependency system and simply specify which libraries you would like to use and Android Studio will automatically fetch the jars from online remotes as required. I think its the future of Android Application Development.

I am new to Eclipse and I could not solve this problem.
How could I import this library to Eclipse using the default builder (not using Gradle)?
Without using Gradle/Maven and using Eclipse you need to manually add the library.
The library is in the jcenter repository, which means there is a jar file available. This jar file can be found here (I'm pretty sure you need the -sources.jar)
Download this library and save it in a logical place. Go to Eclipse, highlight the project and press Alt+Enter. Go to the Java Build Path page and click Add External JARs under the Libraries tab. Select the JAR file and it should be fine.
Keep in mind that the Eclipse ADT plugin is not the way Google wants you to do it. If you have no reason to use Eclipse other than that it's what you have set up now, you should probably move to Android Studio.
Create a new project and add github version project files to newly created project else download the entire project from github and add this project to your current project.
right click(current project) -> Build path -> Configure build path -> Java build path -> Projects (tab) -> click add
Just add this project there and build your project.
I am running eclipse juno on a 64 bit windows 8.1 machine, I have imported a project into eclipse, but the error i am facing is
On reading about it, I came across the solution that I am supposed to configure the build path manually,
but I am unable to do so since,
Please help
In your screen shot I can see app-compact project imported; This should cause your problem. In better word: when you are using app.support.v7 libraries you must import app-compact project in your workspace and add it as your project dependency.
follow below link of developers:
https://developer.android.com/tools/support-library/setup.html
Especially this part will help you:
1- Make sure you have downloaded the Android Support Library using the SDK Manager.
2- Create a library project and ensure the required JAR files are included in the project's build path:
2- Select File > Import.
3- Select Existing Android Code Into Workspace and click Next.
4- Browse to the SDK installation directory and then to the Support Library folder. For example, if you are adding the appcompat project, browse to /extras/android/support/v7/appcompat/.
5- Click Finish to import the project. For the v7 appcompat project, you should now see a new project titled android-support-v7-appcompat.
6- In the new library project, expand the libs/ folder, right-click each .jar file and select Build Path > Add to Build Path. For example, when creating the the v7 appcompat project, add both the android-support-v4.jar and android-support-v7-appcompat.jar files to the build path.
7- Right-click the library project folder and select Build Path > Configure Build Path.
In the Order and Export tab, check the .jar files you just added to the build path, so they are available to projects that depend on this library project. For example, the appcompat project requires you to export both the android-support-v4.jar and android-support-v7-appcompat.jar files.
Uncheck Android Dependencies.
Click OK to complete the changes.
You now have a library project for your selected Support Library that you can use with one or more application projects.
Add the library to your application project:
1- In the Project Explorer, right-click your project and select Properties.
2- In the category panel on the left side of the dialog, select Android.
3- In the Library pane, click the Add button.
4- Select the library project and click OK. For example, the appcompat project should be listed as android-support-v7-appcompat.
5- In the properties window, click OK.
Update
Also you can import and copy the 'appCompact' library directly to your workspace and then add it as you project dependency. Please follow steps in this guide in order to adding the 'appCompact' by this way:
https://yassirh.com/2014/01/getting-the-android-navigation-drawer-to-work-on-old-versions-of-android/
(The above link is in order to using navigation drawer in older version but same objects are using appCompact and using it have same solution for both)
First of all
Make sure that you've installed already the following libraries Android Support Library, Android Support Repository and Google Repository by checking in the Extra folder by openning the Android SDK Manager in eclipse.
if it is already installed then add them to Eclipse
Eclipse -> Import -> Existing Android Code into workspace.
Add /android/adt-bundle/sdk/extras/android/support/v7/appcompat to your Eclipse workspace.
Right click on the project in Eclipse and select properties.
Select Android -> Library -> Add.
Select appcompatv7 project and Save.
Use import android.support.v7.app.ActionBar to import Action bar in activities and fragments.
i am a android app developer and converting myself from Eclipse to Android Studio.
Now i get a difficulty to add library project into another project.
What i can do in Eclipse is very clear:
1.Set project B as library Project (right click->properties->android->is Library)
2.Add this library into Project A (right click->Properties->android->add...->choose Project B->OK
But how can i execute such behavior in AS?
I read article
Create a standalone library with Android Studio
and Create Project A as Library in AS.
Now i create Project B in AS with module BApp,
how can i add Library Project A into B/BApp?
The reason i would not like to copy files of Project A to Project B is, I would also use Library Project A in my many other Project. I dont think it is a good idea that make a hard copy to each Project while i will always update Library A in local.
Appreciation for the Help!
You have to go to Project Structure and add the library as a new module. To do this click on the + icon and select Import Existing Project, once the module is imported go to the Dependencies tab, click on the + icon and select Module Dependency and click on your library.

I have integrated facebook in android. and now when i click on the fb button i get this error.
Found 2 versions of android-support-v4.jar in the dependency list,
If you are adding more than one library project to your project, and these projects requires android support 4 library. then make sure that all of these projects use the same android support library (The newest). So, get the latest version of the library and copy it to the lib folder of your projects.
Try to delete the extra android-support-v4.jar library from libs folder.
Go to libs in project by going to windows explorer and delete the support file in libs.
Now go to workspace and open the appcompat folder copy the v4 file and paste in Yourprojectname>libs
Now goto eclipse and clean the project and restart eclipse
all errors will be gone.
I have an application that I have to look at as a training exercise. It has used few external libraries such as SlidingMenu, ImageViewZoom and ActionbarSherlock.
I have downloaded and extracted those libraries but I have no idea how to add them to my existing project.
For those that are distributed as a simple JAR, do what Emil Adz indicates, and copy that JAR into your project's libs/ directory.
For those, like ActionBarSherlock, that are distribute as Android library projects, you will need to do a bit more work. In the case of Eclipse, you will need to import the library project into your workspace, then go into Project > Properties > Android for your application project and click the [Add] button to add the library project to the application project. For a command-line build, use android update lib-project to link the application and library project together.
You can read more about referencing an Android library project from Eclipse or the command line in the documentation.
You need to import those libraries as Android Project from existing source and mark them as "Is Library" by going into their properties.
Once you marked it as "Is Library" add it to your
project by going into Properties->Android->Library->Add (it will show the list of library you imported).
The Right Way:
What you need to do is to copy the external library (JAR file) to the /libs folder of your project.
That way those libraries will compile with your project and could be use on real device when you deploy your application.
Some times you will need to add a project to your workspace ( For example the Google Map library)
and then add the library reference using the properites -> Android window at the bottom.
You can get an idea of how it's done by reading the first 3 step of this Google Map API V2 guide I wrote. there I reference the android library project:
Google Map API V2 Guide
The Wrong Way:
any other way, like for example adding the files using the properties - > Java build path screen may result in a missing library when you run the project on a real device.
if they are jars the make a libs folder then paste the jar in it and then go to your project buildpath->configure build path->Add Jars-> ok and if it is a library project then go to your project Property->Android->Add(Your Lib Project)->Ok->Apply
