为什么Camera.Parameters.setFocusAreas不能使用某些Android设备？

Question

我正在尝试创建一个使用相机的应用，并尝试在用户触摸相机预览时启用自动对焦。

我使用此方法启用onTouch焦点。

params.setFocusAreas(focusAreas);

它适用于大多数三星设备。

但是当我在任何华为手机上测试时，它都无法正常工作并崩溃。

好消息是，如果我不使用，它在华为上效果很好：

 Huawei Honor 5X (HNKIW-Q), 2048MB RAM, Android 6.0

这是错误日志：

我想弄清楚为什么会出现这种情况并修复它？
