TextRecognizer

Finds and recognizes text in a supplied Frame.

Build new TextRecognizer instances using TextRecognizer.Builder.

Recognition results are returned by detect(Frame). The OCR algorithm tries to infer the text layout and organizes each paragraph into TextBlock instances. If any text is detected, at least one TextBlock instance will be returned.

Adding the ocr functionality dependency to your project's AndroidManifest.xml will indicate to the installer that it should download the dependency on application install.
