Answer 1

public void surfaceCreated(SurfaceHolder holder) {
    // The Surface has been created, now tell the camera where to draw the preview.
    try {
        mCamera.setPreviewDisplay(holder);
        mCamera.getParameters().getSupportedPreviewSizes();
        mCamera.startPreview();
        Log.d(TAG, "Camera preview started.");
    } catch (IOException e) {
        Log.d(TAG, "Error setting camera preview: " + e.getMessage());
    }
}
