Unable to add appcompat support library in eclipse - java

My project(eclipse) has dependencies on android.support.v7.app.AppCompatActivity. I tried the following.
Tried to add the library in my project's Java build path. Didnt work.
Also I observed something weird. The path for support libraries referenced elsewhere in SO is Android\sdk\extras\android\support\appcompat
However in my SDK the path is the following.
Android\sdk\extras\android\m2repository\com\android\support
May I ask why is that so?
Also I copied the appcompat jar file into the libs folder of my project. Still it didnt work.
Could anyone please help?

See this answer
The import android.support.v7.app cannot be resolved
After you add appcompat_v7 to your dependencies, be sure that the libs folder from your project are empty. By default, an android-support-v4.jar is created when you define your project, so this will cause conflict when you declare appcompat_v7 library as your dependency.
So, the first thing you need to do is check the folder .../My_Project/libs and fearlessly delete the file android-support-v4.jar.
Then, add the appcompat_v7 library as a dependency of your project:
To do this, if you are using Eclipse:
Right click in your project folder, located in the Navigator.
Click in properties, in the final of the list.
In the Properties window, select the Android option (left menu).
In the box Library, add your new reference.
Support Library Setup -
https://developer.android.com/tools/support-library/setup.html

Just import the appcompact library in your workspace then simply add this library in your project from properties .
It works for me. I using this. I also provide you library.

unable to find a lib folder in my project

I've been working on some project that involves Jar files to be added to build path. but one of my colleagues said that adding the jars to lib folder is advantageous compared to adding it normally.
Now my problem is, in eclipse, I right click and add a java project, but to my surprise I don't find a lib, earlier when I used to do J2EE apps, I used to find that. please let me know how can I fix this.
Thanks
In eclipse when you create a Java project, it doesn't create the lib folder along with it. This is something you want to do manually. At project level you can right click and add the folder. Then you can paste the jars into the folder, select the jars, right click, build path, Add to Build path.
Alternatively you can directly drag and drop to your Referenced Library. Both the ways are similar in effect, no difference.

Adding Volley library to android project in Eclipse Luna

I've created an Android project in Eclipse and I would like to add the Volley library to it. Searching on the web, I've tried these approaches:
Copy the .jar into the libs folder and right-click and add it to build-path.
Open the library as an android project, mark it as library and add it as a reference in my android app.
Nothing works. I still cannot access the classes provided by the library by importing the classes like follow: com.android.volley
Someone has a solution for this ?
The Solution:
Try this:
Add volley.jar to the libs folder. Don't add it to the build
path.
In Eclipse go to Project and make sure Build Automatically is selected.
Now in Project, click on Clean:
Project -> select Clean -> select the project.
As Volley doesn't have any resources like styles, layouts etc., its not necessary to reference it as a library project. The above should work, provided all steps are followed.
If this doesn't work ...
Make sure the library has not been added to the build path. If it is, then remove it. Now, try:
Closing and re-opening the project.
Restarting the IDE (last resort).
The build process for Volley has changed to Gradle. If you just want to use the library without building it, you can get the Jar from Maven or scroll down to the instructions to building it yourself lower in this answer.
Maven
An easier way to obtain the Jar file is to download it directly from Maven Central. You can find the latest version with this search:
http://search.maven.org/#search%7Cga%7C1%7Cg%3A%22com.mcxiaoke.volley%22
At the time of writing the 1.0.19 version can be found here:
http://search.maven.org/remotecontent?filepath=com/mcxiaoke/volley/library/1.0.19/library-1.0.19.jar
Gradle
The new way to do it is to build the project using Gradle.
You can do this by running:
git clone https://android.googlesource.com/platform/frameworks/volley
gradle build
This will create a file in
build\intermediates\bundles\release
Then add this file into your libs folder and add it to your project.

Including external jars permanently in NetBeans

I'm building a Java Swing Application. This project requires a jar file called JCalender. I've added this to Libraries folder and everything works fine on my computer in NetBeans. But when i open the same project in my friends NetBeans, it doesn't recognizes this library. I've to manually select the file placed inside the projects dist/lib folder. How to avoid this? please help!

You can't avoid this because it's not a problem actually. To compile and run a project you need to have access to the external libraries involved in the development, so if you open your NetBeans project in a different computer than yours you will definitely need to resolve the reference to the external libraries. There's no way for the IDE to do it automatically as far as I know.
Can't i give the relative path to the lib folder for that specific
library somewhere in project properties?
You could just give it a try. IMHO if the real goal is to share a project with other developers then I'd change the strategy. I'd create a Library (Tools -> Libraries) and tell my mates to create the very same library including the JCalendar JAR files in the library's classpath. I'd include this library in the project properties and finally I'd use a versioning tool like Git or SVN to share the project.
By doing this your mates still need a copy of the JAR file wrapped in a NetBeans Library, but the project properties won't point to a fixed/relative path looking for a JAR file but wil include a reference to a given Library. The Library itself will resolve the dependency to the JAR file. If you take a look to the project.properties file you'll see something like this:
javac.classpath=\
${file.reference.jcalendar-1.4.jar}
But if you as I've suggested then you'll see something like this:
javac.classpath=\
${libs.JCalendar.classpath}
Here libs.JCalendar.classpath will resolve the dependency so your mates can have the actual JAR file located in whatever folder they like and the project should compile just fine.
Another option is using Maven to manage the projects dependencies but honestly I'm not a Maven expert so I can't help you in this path.
You need to do a "clean and build" and your jar will be in the dist folder. It will include the external jars
You can read more about it here
I think your problem is due to you are providing absolute path of jar file.
while choosing jar on write side of filechooser there is option of
Relative path and Absolute path there you should click on Absolute path.
i am new to java , but anyway , i have faced the same problem and found a solution for my project
If you are in Netbeans , its would be very easy for you
Let you project name is ABC and all your dependent jar file is under the
the folder MyResourceCollection
now we need to permanently import all jars under this folder ,
So from Netbeans ,
right click on your project name
go to properties
go to library
in the library page , check the "libraries folder" label
you can find a browse button at the right side of the label
click browse and select the MyResourceCollection folder
a new window will come , just press Next-->Next--->Finish
all is done , now check yourself by moving the folder into different location

How do I add a Github library to my Android Project as a JAR in Eclipse?

I'm trying to add https://github.com/astuetz/PagerSlidingTabStrip to my project. Looking at it, I notice that it has files in res and depends on its own R.java file. When I make it a JAR I continue to get errors because the dependencies aren't all there. I'm not sure how to get this to work.
I keep getting errors like
import android.support cannot be resolved and everything else too. I tried referencing different answers on StackOverflow but none of them yielded a working solution.
The resources won't be packaged into the JAR file. Google is working on a new packaging scheme called AAR which is supported by Android Studio.
In order to use this third-party library in your own project, you should clone it to a local repo. Then you can import it directly into your Eclipse workspace and then add the Eclipse project to the classpath of your app's project.
Download the whole source code from https://github.com/astuetz/PagerSlidingTabStrip by git tool.
On your Eclipse IDE, import the library as exsisting source code at Android option.
Add the library your add before into your project.

How to include cardslib to my Android project?

I want to create a GridView like GooglePlay.
I found this library on Github. I don't exactly know how to include it to my project. I tried to add it in "Build Path", but it doesn't work.
Is it possible to export it as a jar file?
You will have to import library directory as a project in your Eclipse just like #ssantos said in the answer. However you have to do one extra thing to make it work.
All the code is in a sub folder called "java". You have to right click on it and make it as source folder.
For more information you can look at the official guidlines https://github.com/gabrielemariotti/cardslib/blob/master/doc/BUILD.md
It seems you can find the library project here.-
https://github.com/gabrielemariotti/cardslib/tree/master/library/src/main
I'd try importing that as a project in your workspace (and mark it as Android library), and then including it in your project Android libraries (Project properties => Android => Library section)
If you're using Android Studio, just add the following to your build.gradle file.
dependencies {
compile 'com.github.gabrielemariotti.cards:library:1.3.0'
}
