please help me. reason?

android photographic camera parameters vary between devices. need verify device supports parameter you're trying set before setting it, see camera setparameters doc

you can query supported parameters :

obtain parameters object : camera.parameters params = mcamera.getparameters();

then query object specific parameter , previewsize:

params.getsupportedpreviewsizes ()
