camera.setParameters failed in android

by

It is failing because not all devices support arbitrary preview sizes. Apparently some do but you can’t rely on it. In your surfaceChanged method you need to do something like this:

public void surfaceChanged(SurfaceHolder holder, int format, int w, int h) {
    Camera.Parameters parameters = camera.getParameters();
    List<Camera.Size> previewSizes = parameters.getSupportedPreviewSizes();

    // You need to choose the most appropriate previewSize for your app
    Camera.Size previewSize = // .... select one of previewSizes here

    parameters.setPreviewSize(previewSize.width, previewSize.height);
    camera.setParameters(parameters);
    camera.startPreview();
}

You’ll have to figure out a way to scale this so that you don’t lose the aspect ratio etc.

For reference here is the Android SDK doc.
