Eclipse上的Alfresco Mobile Android错误

Question

I download alfresco android sdk 1.0.1 from this link then I unzip file.

After that I open my eclipse, create new workspace then click FIle -> Import -> Android -> Existing Android Code Into Workspace -> Root Directory I browse in unzip sdk -> Select All -> Check Copy Projects into workspace -> Finish

Then I Found many error in src directory, for example like this code

@Override
public Loader<LoaderResult<PagingResult<ActivityEntry>>> onCreateLoader(int id, Bundle ba)
{
    if (!hasmore)
    {
        setListShown(false);
    }

    // Case Init & case Reload
    bundle = (ba == null) ? getArguments() : ba;

    ListingContext lc = null, lcorigin = null;

    if (bundle != null)
    {
        lcorigin = (ListingContext) bundle.getSerializable(ARGUMENT_LISTING);
        lc = copyListing(lcorigin);
        loadState = bundle.getInt(LOAD_STATE);
    }
    calculateSkipCount(lc);
    ActivityStreamLoader loader = new ActivityStreamLoader(getActivity(), alfSession);
    loader.setListingContext(lc);
    return loader;
}

Error mark on second line (public Loader ...) Eclipse said:

Multiple markers at this line
- The methode onCreateLoader(int, Bundle) of type ActivityStreamFragment must override a superclass method
- implements android.app.LoaderManager.LoaderCallbacks<org.alfresco.mobile.android.api.asynchronous.LoaderResult<org.alfresco.mobile.android.api.model.PagingResult<org.alfresco.mobile.android.api.model.ActivityEntry>>>.onCreateLoader

That I want to know is what should I do to solve this error? Because I want to build alfresco android with that source code..

Note: I using alfresco-android-sdk-1.0.1, Eclipse SDK Version: 3.7.2, jdk-1_5_0_22-windows-i586-p

Thanks

You're using Java 1.5 (jdk-1_5_0_22-windows-i586-p) to compile your application, you need to upgrade your compiler to 1.6 as some changes were made to the @Override annotation.

In Java 5, the @Override annotation might be applied only to the methods overriding superclass ones. Since Java 6 you can use the @Override annotation also with the methods that implements the interface ones.

There is also a possibility that you may already have it installed, but not set in eclipse - you can change the compiler version in the project properties : Java Compiler -> Compiler compliance level .

Sources:

• build settings for alfresco states it needs 1.6 to compile ( <maven.compile.source>1.6</maven.compile.source> )
