java - NPE when creating visible Activities Robolectric 2.3 -

for illustration have 2 activities mainactivity , nextstartedactivity.

oncreate() method in mainactivity

... intent intent = (new intent(this, nextstartedactivity.class).putextra("start", 1)); startactivity(intent);

for mainactivity invocation works fine

activity = robolectric.buildactivity(mainactivity.class).create().visible().get();

oncreate() in nextstartedactivity

... request_status = getintent().getextras().getint("start"); textureview.setsurfacetexturelistener(this); ...

when utilize invocation above nextstartedactivity, have java.lang.nullpointerexception @ nextstartedactivitytest.java:89 when use

activity = robolectric.buildactivity(nextstartedactivity.class).get();

all works fine.

please, give me understanding in differences of ways different activities. , equal setupactivity()?

if npe occurring on line:

request_status = getintent().getextras().getint("start");

then problem not creating intent in test, code expects. seek this:

intent intent = new intent(robolectric.getshadowapplication().getapplicationcontext(), nextstartedactivity.class); intent.putextra("start", 1); robolectric.buildactivity(nextstartedactivity.class).withintent(intent).create().get();
