I'm followed this IBM Worklight article instructions -
link.
On Eclipse - when I try to run BarcodeScannerSampleBarcodeScannerSampleAppAndroid -
I get message box with title - "Android Launch", that says:"Your projects contains error".
At Markers window I get this Error:
The container 'Android Dependencies' references non existing library
'D:\Users\MyUser\workspaceNew\CaptureActivity\bin\captureactivity.jar'
BarcodeScannerSampleBarcodeScannerSampleAppAndroid
Build path
Build Path Problem
Directory - "D:\Users\MyUser\workspaceNew\CaptureActivity\bin\" doesn't contains "captureactivity.jar" file.
Any idea?
Thanks!
Make sure you follow the instructions in the blog post to the letter.
It sounds like you did not follow the last step, which says to:
Right-click the generated Android project and select Properties
In the Android entry from the left pane, click on Add and select CaptureActivity
Fuller steps:
Download & extract the zip from GitHub: https://github.com/phonegap-build/BarcodeScanner/archive/master.zip
In Eclipse, File > Import > Android > Existing Android Code Into Workspace
Click on Browse and then find the extracted folder
Navigate in it into ../BarcodeScanner-master/src/android/LibraryProject and click Finish
Then you need to continue with creating the Worklight project. It's two different projects.
In your Worklight project, you need to navigate to your-project\apps\your-app\android\native
There you need to right-click on the src folder and select Import... > General > File System
Navigate to the same extracted folder, into ../BarcodeScanner-master/src/android and click Next
Tick the checkbox next to the android option that will appear after step 3
Next you need to configure AndroidManifest.xml and config.xml in the same location (your-app\android\native).
In both the CaptureActivity AndroidManifest.xml and the Worklight project AndroidManifest.xml I've set the minSdkVersion to 19, which I have installed.
Now,
Once you're done with that, build the project.
Right-click on the generated Android project > Properties > Android
Click the Add... button and select the CaptureActivity library
Make sure to not select the "Is library" checkbox.
Looks like you missed one step.
- First we need to import the Java facade to the plugin. This is the code that implements the
mandatory CordovaPlugin class and the exec() method. In the Worklight project, go to the
location for the Java code
BarcodeScannerSample/apps/BarcodeScannerSampleApp/android/native/src
- Right-click on the src folder and select Import...> File System
- Select the directory
<GIT CLONE FOLDER>/BarcodeScanner/src/android
Select File > Import, of type File System, the contents of the com folder from the same
source folder
<GIT CLONE FOLDER>/BarcodeScanner/src/android
You should be able see that the com.phonegap.plugins.barcodescanner.BarcodeScanner.java
file has beenimported into the src folder.
And make sure you configured the config.xml and AndroidManifest.xml properly.
You can find the file here: https://github.com/phonegap-build/BarcodeScanner/
Click on "Clone in Desktop".
Extract the zip file.
Import the resources as following.

Yaniv thanks.
The problem was in CaptureActivity library.
After importing "Existing Android Code Into Workspace", I should BUILD the project library.
Then it create a directory - "D:\Users\MyUser\workspaceNew\CaptureActivity\bin\" with "captureactivity.jar" file in it.
Thanks!

Can anyone give me some instructions of how I'm supposed to install Vuforia in Android Studio? I'm making a new app and I need to use augmented reality with Vuforia. Hope you can help me!
Thanks a lot!
You need to follow following Steps:
Read our Getting Started Guide for instructions on setting up the
Java SDK, Android SDK and NDK:
https://developer.vuforia.com/downloads/sdk
Make sure you have installed the latest version available of Android
Studio from:
http://developer.android.com/sdk/index.html
Use the Android SDK Manager (from within Android Studio) to get the
latest Android SDK and Android Platform and Build tools
Launch Android Studio
Select File - > Import Project ... and browse to the root directory
of the sample Vuforia project you want to open
Proceed in the Import Wizard dialog (click Next, Next) until you
reach a page with this message:
"Alternatively, you can fill in the actual path map in the table below":
click to edit
enter the actual path to the Vuforia.jar library (which is located under your vuforia_install_dir/build/java/vuforia)
In the Project view, right-click on the Project and expand the view
hierarchy so to locate the Vuforia.jar under app > src > main
right-click on Vuforia.jar to open the context menu
click on the "Add as library..." option in the context menu
Alternatively, if you cannot locate the Vuforia.jar in your project
hierarchy:
right-click on the Project and select, "Open Module Settings"
select "App"
then select the "Dependencies" tab
Click on the "+" button to Add a File Dependency and browse to the
Vuforia.jar file
Create a folder called "jniLibs" under the "app/src/main" folder under your Android Studio project directory
Copy the "armeabi-v7a" folder (including the libVuforia.so file
located inside it) from the "vuforia_install_dir/build/lib" to the
"app/src/main/jniLibs" folder
the resulting directory structure under your project root should be:
/app
/src
/main
/jniLibs
/armeabi-v7a
/**libVuforia.so**
If your project includes a "jni" folder, move it to a location
outside of your project (otherwise Android Studio may attempt to
compile the sources in that folder and may fail)
Clean and rebuild the project
Run the app on your device
Best Luck :)
answer from here and work for me:
(Seems like the project needs access to the Vuforia.jar file and can't access it outside of the sample folder(?))
So,
copy the Vuforia.jar file from the folder \vuforia-sdk-android-x-x-x\build\java\vuforia to a folder in the sample project, e.g. to \samples\app\libs
(it's important it's in the "\app" path, so you can find it in the next step)
in Android SDK hit F4 (or right click on the app folder in the project structure and click on "Open Module Settings".
Select the tab "dependencies", click on the "+" to add a dependency and select "2 File dependency".
Now select the above path and file ((\samples\app) \libs\Vuforia.jar) and the project will run just fine...
Good luck.
I am trying to move a project from one computer to another and having issues. I have tried.
File > New > Project ... > Android Project from Existing code
and
File > Import > Android > Existing Android Code Into Workspace.
Both look like they get me to the same place. I browse to the project location check the option to copy in existing workspace. When a click finish nothing happens. The dialog stays open and the project is to imported or opened.

Maybe there is already a project in your workspace with same name. Check your workspace and rename that project.
Simple export method I tend to follow:
Save everything
Close Eclipse (And wait to completely close)
Then goto workspace folder
Select the project you're working on
Either simply copy to new location or compress to zip
Then using new system, either file open project by folder or zip
To open compressed project or copied folder:
File ---> Import
General ---> Existing Projects into Workspace
Browse either root directory or archive file
Screenshots below:
I'm following this guide:

Follow the steps below to add HoloEverywhere
Download Zip from GitHub to your computer UnZip the folder Go to
eclipse and choose File->New-> Android Project
Select Create project from existing source and then browse to the HoloEverywhereLib folder
inside extracted folder
Press Finish
Right click on the newly created project and go to Properties. Under the Android heading, you should see a section for Library with a checkbox IsLibrary. Make sure that's checked and press Add and previously added library ActionBarSherlock.
I unzipped the folder. Then went to eclipse -> Right click -> Import -> Android -> Existing Android Code into Workspace.
I select the unzipped folder and It's showing this:
When I click Finish:
And then if I create a new project, and try to import it, It cant find the library; I type org. and it isn't showing up the rest (org.holoeverywhere.app.***Activity). (Like its github says https://github.com/Prototik/HoloEverywhere#how-to-use-maven)
Can you help me out?
Edit: I've also tried to remove src from .classpath files with same result
Clone the repository using Github desktop. Install eGit on Eclipse. Then use import-->Git-->Projects from Git.
i've been struggling with this issue for a couple of days now...
ill explain my problem in a nutshell....
i have a simple java project (not android library or something more complex) which i want to use as my model..
lets assum it is called mymodel and it has a simple class Model.
i also have an android application myandroidapp and in the main activity i want to create an instance of the class Model.
I can add the mymodel as a project to the build path and compile but when i run this application it throws class not found exception. how can i make it work?
please help.
thanks
Step #1: Create a JAR based on your "simple java project"
Step #2: Put the JAR in the libs/ directory of your Android project
And you're done.
Never mess with the build path of an Android Eclipse project manually.
In Eclipse, you can follow the following steps:
Creating JAR file
Right-click on the root of the mymodel project and click on 'Export...'
In the window that appears, expand the 'Java' category/folder, choose 'JAR file' and click 'Next'
In the next window, choose the options you desire, especially pay attention to where the 'export destination' is. When you're done, click on 'Finish'. The JAR file will now be located at the 'export destination'.
Adding JAR to Android project
In your android project (myandroidapp), copy the JAR file into the libs/ folder. You can do this by simply copy and pasting or dragging and dropping etc.
Then, right-click on the JAR file that is now in the libs folder, go on 'Build Path' and from the menu that appears, click on 'Add to Build Path'
You should now be able to use this JAR file in your Android project.
I'm pretty new to android, and just finished setup my environment and reading some tutorials. Then I got sdk samples from the web. Okay, what I wanna ask you is that is there a way to start a sample as a project in the Eclipse? I mean like clicking a project file in c# or a solution file.
Here is my folder which I unzipped the code,
\android-sdk-windows\samples\android-8\NotePad
There are three folders and one file in the folder, \res, \src, \tests, and AndroidManifest.xml
Or, do I need to make a new android project and import (or add files? maybe) them?
Thanks in advance,

I don't think that's a very good way of doing it. Sadly the 'Create Project from existing sample' feature you describe functions in such a way that when it creates a project from a sample it leaves you editing the source code in the actual SDK sample itself instead of a copy of the source imported into your Eclipse workspace.
This is problematic for a number of reasons including:
Once you've edited the new project you no longer have the original sample to refer to, which is the whole point of the samples in the first place.
If you want to hack a sample in several different ways you will want several copies of the sample, but again once you've edited the original sample you no longer have the original sample to make a copy from.
If the SDK is ever patched then when you update it you may end up overwriting your code.
In short it makes far more sense to treat the SDK as a readonly reference and not treat it as a sandpit in which to do your own messing around. So imo the best way to create an Eclipse project from a sample is do take a copy of the sample and put it somewhere else.
If you want the sample to not exist in your actual Eclipse workspace directory then this is very easy. Just copy the sample to a new location and inside Eclipse with your workspace open do New->Android Project and 'Create Project From Existing Source'.
If on the other hand you want to make the project inside your Eclipse workspace directory then there is a problem which is that if you just copy the sample code inside your workspace folder and do 'New->Android Project' and 'Create Project From Existing Source' for me at least it fails with the error "Invalid project description: c:\Users\usernamme\blah\blah\projectname overlaps the location of another project projectname". I don't know why, if you create a project from sample code using 'New->Java Project' it works just fine so I suspect there is a problem with the Android Project Eclipse plugin that is causing this to fail.
There is a way to get around this which is to first copy the sample code to a temporary location on disk that is outside of the workspace directory. Then use New->Android Project and 'Create Project From Existing Source' which turns the temporary copy of the sample code into a project but leaves it orphaned outside the workspace directory. Then delete the project from the workspace (but without deleting the project from disk). Then use Import->Existing Projects Into Workspace with the 'Copy Projects Into Workspace' checkbox ticked to copy the project into the workspace directory, before finally deleting the project from the temporary location.
But ultimately I decided to structure my workspace in such a way that projects are not inside the workspace folder like this:
Eclipse Workspaces
\
Android Projects
\
Workspace
Project 1
Project 2
Java Projects
\
Workspace
Project 1
Project 2
Other Projects
\
Workspace
Project 1
Project 2
In this layout the Android Projects, Java Projects and Other Projects directories are conceptually my workspaces but in reality in each case it is the nested Workspace folder which is the actual Eclipse workspace. This enables me to keep my projects contained within their respective pseudo-workspaces while not being inside their actual Eclipse workspace folder which neatly gets around the problem of not being able to easily create Android projects if the project directory is inside the Eclipse workspace directory.
Sorry that's all a bit long winded, but it's taken me ages to work out how to get this to work efficiently and I figure it might help someone.
From eclipse go to: File > New >
Project...
Select the Android Folder and pick
Android Project
Then in the Contents section at the
top click the "Create project from
existing sample" radio button. Once
you pick a target from the bottom
the drop down will become selectable
and your good to go.
Copy the downloaded project into your workspace
i.e space allocated for android project
Open the Eclipse
Choose File---> Import ---> Android --> Existing Android code into workspace
Choose Next
Click Browse
choose the foldername (downloaded)
click finish
If you are using ADT 20 then it's quite easy. Select New > Other...>Android Sample Project > [Select the platform from which you would like to pick the sample] > You must see the available samples, select the one you wish to open,you will see that in your workspace.
This may not be a definitive answer because I'm relatively new to Android as well (and come from more of a .Net background too).
When you create a new Workspace in Eclipse, you'll see a new folder created with the name of your workspace and a .metadata folder inside of it. I don't think there's a "workspace file" per se, so you don't double click anything to bring it back up. You just open to that workspace (by telling the Eclipse dialog what path to open).
As far as importing existing projects into a workspace, copy the whole folder into your workspace and click File - Import... - General - Existing Projects into Workspace. Click the Browse button to select the Root directory and it should default to the Workspace's main folder. Click OK and the project should show up in the dialog. Select it and click Finish
The code samples don't come with eclipse project files out of the box. There are a number of ways to create them but the easiest is probably this. From eclipse (with the android plugin installed), File -> New -> Project, Android Project, Next, select the "Create project from existing source" radio button and specify the location of the existing source. The project wizard should then find your manifest and fill out the rest of the information it needs automatically.
http://developer.android.com/samples/index.html
It states here:
"Using Android Studio
Unpack the downloaded project package.
In Android Studio, chose File > Import Project and select the root folder of the unpacked project.
Android Studio may ask you to choose the type of project you are importing. If this is the case, make sure to choose Import project from external model and select the Gradle option."
I hope this helps you.
