resize - Android: resizing a surface from a surfaceview -

-

i using tutorial camera2 api android , 1 of steps resize textureview's surface acceptable format doing following:

 surfacetexture surfacetexture = mtextureview.getsurfacetexture();  surfacetecture.setdefaultbuffersize(mpreviewsize.getwidth(), mpreviewsize.getheight();  surface previewsurface = new surface(surfacetexture);  previewbuilder = cd.createcapturerequest(cameradevice.template_preview);  previewbuilder.addtarget(previewsurface);

so mpreviewsize variable of type size , determined beforehand cycles through acceptable formats , selects optimal 1 according screen size. problem i'm using surfaceview , i'm trying resize surface object in surfaceview tried didn't work:

            surfaceholder sh= gamesurface.getholder();             sh.setfixedsize(mpreviewsize.getwidth(), mpreviewsize.getheight());             surface sur = sh.getsurface();             previewbuilder = cd.createcapturerequest(cameradevice.template_preview);             previewbuilder.addtarget(sur);

so in debug mode see mpreviewsize correct (as in set acceptable format) error saying i'm trying use unacceptable format size, shows size , it's not same mpreviewsize means resizing isn't working. ideas?

you need wait receive surfacechanged callback surfaceview, before trying use surface create camera capture session.

setfixedsize doesn't take effect immediately.
