本文详细介绍了如何在CameraConfigurationManager.java文件中进行修改，以实现更智能地调整相机分辨率，确保预览尺寸始终为480*320或320*480等常见比例，提高用户体验。

更改CameraConfigurationManager.java文件

在 Log.d(TAG, "Screen resolution: " + screenResolution);这句之后增加
Point screenResolutionForCamera = new Point();
        screenResolutionForCamera.x = screenResolution.x;
        screenResolutionForCamera.y = screenResolution.y;
        // preview size is always something like 480*320, other 320*480
        if (screenResolution.x < screenResolution.y) {
        screenResolutionForCamera.x = screenResolution.y;
        screenResolutionForCamera.y = screenResolution.x;
        }
再更改cameraResolution = getCameraResolution(parameters, screenResolution);为cameraResolution = getCameraResolution(parameters, screenResolutionForCamera);
