i running android unit tests using robolectric 3.0 , have run in runtime exception. tests pretty gives same exception.

i have tried many suggested options such adding --rerun-tasks script parameters, uncheck "use in-process build" option in compiler -> gradle settings of android studio etc..but none of them have worked.

here sample of build.gradle dependency list: 

dependencies {     compile filetree(dir: 'libs', include: ['*.jar'])     compile ('com.android.support:appcompat-v7:18.0.0'){         force = true     }     compile ('com.android.support:mediarouter-v7:18.0.0'){         force = true     }     compile 'com.google.android.gms:play-services:6.5.87'      testcompile 'junit:junit:4.12'      testcompile 'com.github.tomakehurst:wiremock:1.46'      testcompile 'org.bouncycastle:bcprov-jdk15on:1.50'      testcompile ('org.robolectric:robolectric:3.0-rc3'){         exclude group: 'commons-logging', module: 'commons-logging'         exclude group: 'org.apache.httpcomponents', module: 'httpclient'     }     testcompile 'org.robolectric:shadows-support-v4:3.0'     testcompile 'org.robolectric:shadows-httpclient:3.0'     testcompile 'org.robolectric:shadows-maps:3.0' }

have spent many hours looking in no result. highly appreciate in regard.

thanks!

i have data grid rows represent theta (0, pi) , columns represent phi (0, 2*pi) , f(theta,phi) density of dark matter @ location. wanted calculate power spectrum , have decided use healpy. what can not understand how format data healpy use. if provide code (in python obvious reasons) or point me tutorial, great! have tried hand @ doing following code: #grid dimensions nrows*ncols (subject change) theta = np.linspace(0, np.pi, num=grid.shape[0])[:, none] phi = np.linspace(0, 2*np.pi, num=grid.shape[1]) nside = 512 print "pixel area: %.2f square degrees" % hp.nside2pixarea(nside, degrees=true) pix = hp.ang2pix(nside, theta, phi) healpix_map = np.zeros(hp.nside2npix(nside), dtype=np.double) healpix_map[pix] = grid but, when try execute code power spectrum. specifically, : cl = hp.anafast(healpix_map[pix], lmax=1024) i error: typeerror: bad number of pixels if point me tutorial or edit code great. more specifications: data in 2d np array , can change numrows/...
