Importing and using a library in android studio

I am using android studio to import this project called https://github.com/Pixate/pixate-freestyle-android. However when I import it into android studio the folder under samples, freestyleshowcase doesnt seem to build. The other 2 samples buld correctly. There is a red circle around the java file with a J (error) but there is no error in the file itself. COuld someone please help me out?

You are obviously missing some libraries but it is going to be hard for anyone to tell you which since we do not know the libraries the project needs.You can try Build-->Rebuild Project or Build-->Clean Peoject if it still doesn't work, close and open Android Studio.
If that doesn't work also then you have to go the hard way of identifying the libraries need by the project samples you imported and see if you have them.

When in doubt, you can try the Library Dependency option (using Maven) as demonstrated here:

That way, you won't have to manually edit the build.gradle file.

Android Facebook-SDK

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.

SmartWatch sample installation

I would like to compile the sample provided by Sony for his SmartWatch. I followed the instructions in this page. But when I added the the SmartExtensionUtils project I saw lot of errors like: com.sonyericsson.extras.liveware.aef cannot be resolved to a variable. Instead this import com.sonyericsson.extras.liveware has no problem.
Did someone find and solve this issue?

In order for the EightPuzzleGame to compile, you need to add the following library projects that are available in the SDK:
SmartExtensionAPI
SmartExtensionUtils
SmartExtensionInternalUtils
In your case, it is the API project that is probably missing. You can see what library projects that are missing by checking the project properties. Example:

What you need to do is go to the properties page of the SmartExtensionUtils library and in the library box add SmartExtensionAPI as a dependency

This is a link to my desktop screenshot. SmartExtensionAPI and utils are in the project list (left side) but the EightPuzzleExtension does not find them

You don't need SmartExtensionInternalUtils project. When you create project from existing source, check Import project into Workspace. In this way EightPuzzle, SEAPI and SEUtils will be in the same directory and you'll not have no errors :)

I had this problem too. What i did is to solve it, is to import from the Sony samples in the Sony add-on SDK 3.0 the SmartExtensionAPI first and than SmartExtensionUtils. If these samples are build correctly the other samples will build correctly as well.
Go to File|Import, choose SmartExtensionAPI as your root directory and click finish. Maybe you have to change the compiler compliance level to build it correctly. After this do the same for SmartExtensionUtils.

Action Bar for android < 3.0

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.

android smspopup

i downloaded the smspopup app for android from android-smspopup using svn, now i opened the project in eclipse. i did the following:
1) Build Project;
2) Android Tools -> Fix Project Properties;
3) Project -> Clean.
Now, for the following java classes:
1) SmsPopupActivity;
2) SmsPopupPager.
It says that it cannot resolve the following:
import com.jakewharton.android.viewpagerindicator.CirclePageIndicator;
I downloaded the Android-ViewPagerIndicator. Now, i try to add it using the Properties -> Android -> Add Library. But it does not let me add anything. Please can you help me to resolve this problem... I would really appreciate if someone could explain how to solve this problem step-by-step. Thanks a lot in advance!!!

I encountered the same problem with you,and i finally found the solution on the site of https://github.com/JakeWharton/Android-ViewPagerIndicator.
Android-ViewPagerIndicator is presented as an Android library project. A standalone JAR is not possible due to the theming capabilities offered by the indicator widgets.
You can include this project by referencing it as a library project in Eclipse or ant.
