java - NoClassDefFoundError when running from the comand line -

-

i use external library (e.g. google's guava) java program. use eclipse, downloaded guava's jar (and source) , followed adding java library project classpath add eclipse , buildpath of project.

this works fine: can run program eclipse , runnable jar export eclipse, error when try run directly bin/ dir, used before:

exception in thread "main"
java.lang.noclassdeffounderror: com/google/common/base/joiner

what should do?

if you're running class file directly project bin directory may have specify classpath manually: c:> java -classpath c:\java\myclasses;c:\java\otherclasses myclasshere

unit testing - How to mock PreferenceManager in Android? -

-
i've written class using context , third party library , sharedpreferences preferencemanager . it's possible mock context , third party library can mocked using mocking framework, preferencemanager ? i have 2 methods: public void savestring(thirdpartyobject obj) { sharedpreferences apppreferences = preferencemanager.getdefaultsharedpreferences(mcontext); sharedpreferences.editor editor = apppreferences.edit(); editor.putstring(mcontext.getstring( r.string.preferences_string_name), obj.getstring()); editor.commit(); } and corresponding, loads preferences. it doesn't want mock instance of preferencemanager (which used in preferencefragment or preferenceactivity ). you want either: a mock sharedpreferences , in case can mock context#getsharedpreferences (which called preferencemanager#getdefaultsharedpreferences anyhow). you'll have make mock sharedpreferences.editor if preferences edited, above. know how moc...
