高通android9.0 camera API1底層調用為HAL3而非HAL1

高通android9.0 camera API1底層調用為HAL3而非HAL1，若需要調用HAL1的效果，打開攝像頭需要按如下方法打開：

 

 

        try {
            Class<?> cameraCalzz = Class.forName("android.hardware.Camera");
            Method openLegacy = cameraCalzz.getMethod("openLegacy", int.class, int.class);
            camera = (Camera) openLegacy.invoke(null, cameraId, 0x100);//CAMERA_HAL_API_VERSION_1_0 = 0x100

        } catch (Exception e) {
            e.printStackTrace();
        }
