java - Content-Length header already present -

-

i using apache httpclient (4.1) included in android execute httpput. have verified have 1 content-length header. however, every time send request, protocol exception content-length header specified.

httpclient client = new defaulthttpclient(); putmethod = new httpput(url + encodedfilename); putmethod.addheader(..)  //<-once each header putmethod.setentity(new bytearrayentity(data)); client.execute(putmethod);  //throws exception

caused by: org.apache.http.protocolexception: content-length header present @ org.apache.http.protocol.requestcontent.process(requestcontent.java:70) @ org.apache.http.protocol.basichttpprocessor.process(basichttpprocessor.java:290)

any ideas?

i've not used httpclient myself, suspect problem putmethod.setentity(...) implicitly supplying content length , setting explicitly via 1 of putmethod.addheader(...) calls.

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...
