android - Orientation differences between Galaxy Tab and Transformer -


i developed augmented reality application using front-camera , min3d library. application works fine on samsung galaxy tab 10,1 (first generation), running android 4.0.4

but testing same application (landscape mode only) on asus transformer tf700t android 4.1.1 give wrong orientation , augmented world not match more camera view.

the following code used getting orientation vectors target_axis , up_axis needed min3d:

sensormanager.getrotationmatrix(mr, null, mlastaccelerometer, mlastmagnetometer);  sensormanager.getorientation(mr, morientation); number3d target_axis = new number3d( -mr[2], -mr[5], -mr[8] ); number3d up_axis = new number3d( mr[1], mr[4], mr[7] );

the mlastaccelerometer , mlastmagnetometer received onsensorchanged(sensorevent event)

can tell me if above code still device dependent? expect using sensormanager's gerorientation call solution should work throughout different devices?

my guess related orientation of device, i.e. portrait, landscape, reverseportrait, reverselandscape etc. code posted naive, because doesn't take account of rotation of device relative default orientation. use following calculate azimuth adjustment

int rotation = activity.getwindowmanager().getdefaultdisplay().getrotation(); float screen_adjustment = 0; switch(rotation) {     case surface.rotation_0:   screen_adjustment =          0;         break;     case surface.rotation_90:  screen_adjustment =   (float)math.pi/2; break;     case surface.rotation_180: screen_adjustment =   (float)math.pi;   break;     case surface.rotation_270: screen_adjustment = 3*(float)math.pi/2; break; }

which use in answer android compass can compensate tilt , pitch. other people suggest using sensormanager.remapcoordinatesystem(float[], int, int, float[]) depending on rotation number is.

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;} }
