Use procedure 2 (when preview has already started)
Important points
After setting the preview resolution in setPreviewSize,
be sure to perform
setParameters
. Changed content is not reflected until setParameters is executed.
When the preview has already started, use stopPreview to temporarily stop the
preview.
Each preview resolution has a limited combination of frame rates and camera
modes. Note that a run-time exception will occur in setParameters for
combinations that exceed the limit.
You cannot set 5M or 8M as the preview resolution. If you want to acquire images
in 5M or 8M, perform shooting by using takePicture.
The resolution set for preview resolution uses image data acquired in
PreviewCallback.
/*Stop preview*/
camera.stopPreview();
/*Acquire current parameter (or default value)*/
Camera.Parameters params = camera.getParameters();
/*From here on, use procedure 1*/
