Issue using as Library Project

[GoogleCodeExporter]

I dont seem to be able to use this as a Library Project.

When imported into my workspace, all is fine.
But adding it into my project as an Android Library Project causes errors 
relating to the main.xml fie in the library project.

Any suggestions or guides on how we are suppose to use this? Should we just be 
copying the class files and using them directly?

I found the issue. Because the Example Project is built into the Coverflow 
project, it causes issues. Stripped it down, and all is fine now

I think I have the same problem...

/shared/eclipse_workspaces/android/coverflow/res/layout/main.xml:4: error: No 
resource identifier found for attribute 'imageWidth' in package 
'pl.polidea.coverflow'

What did you need to strip out to make it work?

Just replace 
xmlns:coverflow="http://schemas.android.com/apk/res/pl.polidea.coverflow"
with xmlns:coverflow="http://schemas.android.com/apk/res/<your applicatio 
package>"
your applicatio package is the package=".." attribute in AndroidManifest.xml

I am still getting the problem after changing the application package name in 
main.xml to the same name as in the manifest.xml

I assume it is resolved as invalid...

Sorry, I'm trying to figure this out as well. My goal is to learn how to use 
android-coverflow properly as a library, so I thought it would make sense to 
make a separate project that used the supplied test code.

Here are the steps I took:
- Excluded CoverFlowTestingActivity.java from android-coverflow and built the 
jar.
- Created a new project called CoverFlowTesting.
- Added android-coverflow as to the project as a library.
- replacing the class definition in the generated CoverFlowTestingActivity.java 
file in my new project with the class definition from 
CoverFlowTestingActivity.java in the android-coverflow project.
- replaced the contents of my main.xml with the contents of main.xml from the 
android-coverflow project and fixed up the namespace declarations

At this point, my project compiles cleanly, but when I run it in, it crashes 
with "java.lang.RuntimeException: Unable to start activity 
ComponentInfo{com.superluminal.coverflowtesting/com.superluminal.coverflowtestin
g.CoverFlowTestingActivity}: java.lang.NullPointerException". The NPE occurs on 
the line

  mCoverFlow.setAdapter(coverImageAdapter);

in CoverFlowtestingActivity.setupCoverFlow().

I must be missing something, any clues?

Thanks in advance for your help.

Sorry guys, still an Android newbie here. The answer was to change the 
onCreate() code to use the R instance to get the resource IDs. The app is 
working now.

HI, 

I've managed to clone the code and Extract it from HG, but now when I wan't to 
use it as library, have no chance to set it up. 

I've deleted example part, and layout, and I'm trying to embed it to my 
activity, but looks like I'm not getting anywhere. 

Is there any tutorial or the proper way how to implement this code?

Add the attrs.xml file into your res/values folder.. worked fine for me ^^

For an API 17 app using android-coverflow as a library project, I resolved this 
issue by adding the following line just after the xmlns:android attribute in 
the top-level element of my layout:

xmlns:coverflow="http://schemas.android.com/apk/res-auto"
