安卓手机 wx 6.7.3  camera.takePhoto无效，iphone正常  （安卓昨天还可以，今天不行了）

以下代码 三个回调函数都不执行

<camera device-position="front"
        flash="off"
        bindstop="cameraBindstop"
        binderror="cameraAuthFail"
        style="width: 100%; height: 300px;"></camera>

const cc = wx.createCameraContext()
cc.takePhoto({
  quality: 'high',
  success(res) {
    console.log('success')
    console.log(res)
  },
  fail(res) {
    console.log('takePhoto fail res')
    console.log(res)
  },
  complete(res) {
    console.log('takePhoto complete res')
    console.log(res)
  }
})
