java.lang.RuntimeException: setParameters failed in Camera Api

Question

I am developing Camera overly app in that i am using camera api for preview and overlay effects.I am getting force close error in some mobiles and it is not happening other mobiles.

My code:

parameters = camera.getParameters(); 
List<Size> sizes = parameters.getSupportedPreviewSizes(); 
Size optimalSize = getOptimalPreviewSize(sizes, w, h); 
parameters.setPreviewSize(optimalSize.width, optimalSize.height);
parameters.setColorEffect(Camera.Parameters.EFFECT_SOLARIZE);
setCameraDisplayOrientation(MainActivity.this,0, camera); 
camera.getParameters(); 
camera.setParameters(parameters);

These are the call stacks I am getting

Android Camera Parameters vary between devices. you need to verify that the device supports the parameter you're trying to set before setting it, see this Camera SetParameters Doc

You can query the Supported Parameters by :

• Obtain a Parameters object : Camera.Parameters params = mCamera.getParameters();

• Then query that object for specific Parameter , say PreviewSize:

  params.getSupportedPreviewSizes ()
