将外部库导入Eclipse-Android

Question

I want to use the UnifiedPreference library in my app. I've imported the library into my workspace, then added the new project into my existing project by adding it as a library under Properties -> Android. However I'm getting the following errors when I try to build my project which are coming from the UnifiedPreference project:

Console:

[2013-04-08 23:06:29 - unified-pref-library] ERROR: In <declare-styleable> PreferenceHeader, unable to find attribute icon
[2013-04-08 23:06:29 - unified-pref-library] ERROR: In <declare-styleable> PreferenceHeader, unable to find attribute title

The relevent logcat errors seem to be:

PreferenceHeader_title cannot be resolved or is not a field UnifiedPreferenceHelper.java    /unified-pref-library/src/net/saik0/android/unifiedpreference   line 435    Java Problem
PreferenceHeader_title cannot be resolved or is not a field UnifiedPreferenceHelper.java    /unified-pref-library/src/net/saik0/android/unifiedpreference   line 299    Java Problem

Have I imported the library incorrectly? I've tried cleaning and building both projects without anything changing.

Answer 1

In Eclipse:

1. On the Package Explorer
2. Right click in your Proyect > Properties
3. Select: Java Build Path
4. Select and enable Android Dependencies
5. Put on the top in the list
6. Click: OK

Answer 2

Figured it out, seems UnifiedPreference requires a dependency for ActionBarSherlock. Thanks to tttony for putting me on the right track though.
