java - Resources$NotFoundException when calling Robolectric.buildActivity() -

i using robolectric 3.0 rc3 unit testing in android studio. , getting resourcenotfoundexception every time run test. please me resolve issue.

build.gradle

dependencies {     testcompile 'junit:junit:4.12'     compile filetree(dir: 'libs', include: ['*.jar'])     compile 'com.android.support:appcompat-v7:22.0.0'     testcompile 'org.mockito:mockito-core:1.9.5'     testcompile 'org.robolectric:robolectric:3.0-rc3'     compile 'com.ibm.icu:icu4j:53.1' } 

test class

@before public void setup() throws exception {     activity = robolectric.buildactivity(mainactivity.class).create().get(); } @test public void pressingthebuttonshouldstartthelistactivity() throws exception {    //something test } 

so, whenever robolectric.buildactivity() resources$notfoundexception. resource #0x7f040016 points r.layout.activity_main(xml). following id stack trace-

mainactivity.java:15 setcontentview(r.layout.activity_main);

mainactivitytest.java:32 activity = robolectric.buildactivity(mainactivity.class).create().get();

is test class annotated correctly? , using correct path manifest file? following works me:

@runwith(robolectrictestrunner.class) @config(manifest = "src/main/androidmanifest.xml", emulatesdk = build.version_codes.lollipop) public class myactivitytest { .... } 

removing config annotation causes resourcesnotfound exception mentioned.
