christopherperry / robolectric-library-resource-loading.java
Created August 30, 2012 21:32 — forked from pplante/robolectric-library-resource-loading.java
Robolectric does not support loading resources from an Android Library project such as ActionBarSherlock of FlyInMenu, so this patch allows you to specify a library project to load resources in tests.
// In ResourceLoader.java I added the following method:
//
public void loadLibraryProjectResources(File libraryProjectRoot) throws Exception {
File systemResourceDir = getSystemResourceDir(getPathToAndroidResources());
File localValueResourceDir = getValueResourceDir(libraryProjectRoot);
File systemValueResourceDir = getValueResourceDir(systemResourceDir);
loadStringResources(localValueResourceDir, systemValueResourceDir);
loadPluralsResources(localValueResourceDir, systemValueResourceDir);
loadValueResources(localValueResourceDir, systemValueResourceDir);
^(.*(ClassNameOne|ClassNameTwo|ClassNameThree)).*$
