推荐答案

晴这取决于设备的硬件和大部分设备现在不允许同时使用的两个照相机。即使有些设备将能够使用这两款相机，如果你想上尽可能多的设备上运行完美尽可能应用（这是你想要的），你不应该实施该解决方案。谷歌表示：

Mostly it depends on the hardware of the device and most of the devices now do not allow use of both cameras simultaneously. Even if some device will be able to use both cameras, if you want to make application that runs flawlessly on as much devices as possible (and this is what you want) you should not implement this solution. Google says:

为了您的应用程序能与更多的设备兼容，
  不应该让有关设备的摄像头规格假设

In order for your application to be compatible with more devices, you should not make assumptions about the device camera specifications

你可以做什么，这取决于你正在写是与前置摄像头，第二次与相机背面定期拍照一旦应用程序。

What you can do, and it depends on the application you are writing is to periodically take pictures once with the front camera and the second time with the back camera.
