Google Vision 无法创建 TextRecognizer 的实例

Question

我有一个曾经使用 Android Studio 2 的项目；现在，在更新到 Android Studio 3 后，我的应用程序在到达以下位置时崩溃： TextRecognizer textRecognizer = new TextRecognizer.Builder(context).build();

你知道为什么会这样吗？

  @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    try
    {
        //here it fails
        textRecognizer = new TextRecognizer.Builder(this).build();
    }
    catch (Exception e) {
        Toast.makeText(this, e.getMessage() + " Unable to write to external storage.",
                Toast.LENGTH_LONG).show();
    }
