java - Loading a native library in an Android JUnit test -


i've generated native library using ndk-build i'm able load , use in android application. however, want write tests against part of app.

when calling native function in tests, recieve exception message:

java.lang.unsatisfiedlinkerror: no process in java.library.path

...where process native library import, named libprocess.so.

i'm using roboelectric tests, , running particular 1 robolectrictestrunner, if makes difference.

how can test project 'see' native library?

edit: i'm loading library in app so: 

static {     system.loadlibrary("process"); } public static native int[] process(double[][] data);

calling process.process(array) works fine in app (the library loaded), fails when run tests exception given above.

edit 2: if set -djava.library.path="<the directory of libprocess.so>" vm argument, then:

system.out.println(system.getproperty("java.library.path"));

does show path set, still same exception. i'm setting directory as:

<project-name>/libs/x86

...but absolute path.

i've switched default testing style (using activityunittestcase instead of roboelectric) , it's running fine. it's shame have sacrifice speed of test running, running tests on emulator works. create shadow class jni class, detailed here:

robolectric tanks on application objects load jni libraries. can workaround?

perhaps compiling library machine have worked, couldn't spend more time on it.

css - Text drops down with smaller window -

i've adapted css use in website , can't quite figure out why 1 aspect of page acting way acting. basically, when shrink window below size horizontally, of text "drops down". becomes issue if user viewing website through ipad vertical orientation. can view issue here . i'm hoping make if window gets smaller, placement of text remains intact. the problem area not have enough space put both side navigation , content on 1 line. make automatically adjust page's width when exceeds decrements of width. this code example, , highly unlikely work. if see css more clearly, provide exact code. @media , (max-width:960px) { /* assuming #wrapper 960px across */ #content {width:560px;} /* opposed 720px */ } edit the content drops down @ 980px, have shrink width after there. @media , (max-width:980px) { #container {width:520px;} }
