Question

我正在尝试测试谷歌移动视觉API，用于人脸检测，所以我开始使用GitHub mobile vision的演示。我尝试了两个应用程序，FaceTracker和照片演示，下载原生面部检测器库也出现了同样的问题。

对于Nexus 5x，Galaxy S6 Edge无法正常工作，Galaxy S4，Galaxy Alpha正在使用。

我在日志中看到的，不工作时是：

在对日志进行一些挖掘后，通过对标签应用视觉过滤器，我看到：

类似的问题：

Google Vision barcode library not found
FaceDetectorHandle﹕ Native face detector not yet available. Reverting to no-op detection

通过释放空间，清除缓存，没有结果来尝试解决方案。

接下来我该怎么办？是否可以手动下载库？有没有人清楚地表明为什么图书馆不下载？

修改

所以看起来Mobile Vision api https://github.com/googlesamples/android-vision/issues/98存在问题。希望开发人员尽快找到解决方案。

修改

通过更新播放服务库解决了该问题。

Answer 1

根据Google Play Services v9.0的发行说明，该服务中存在一个错误，但已被禁用。

在v9.2版本中，它再次启用。查看发行说明： https://developers.google.com/vision/release-notes#bug_fixes

Answer 2

我的问题是文字（TextRecognizer）没面子，问题是存储，我有300MB免费但是根据这个链接需要10％的手机
