enter image description here

in surfacecreated method need this:

camera.parameters parameters = camera.getparameters(); list<camera.size> previewsizes = parameters.getpreviewsizes();  // need choose appropriate previewsize app // example camera.size previewsize = previewsizes.get(0); camera.size previewsize = // .... select 1 of previewsizes here  parameters.setpreviewsize(previewsize.width, previewsize.height); camera.setparameters(parameters); camera.startpreview();
