Classic UI for the Android Text Pattern Scanner Module

Overview​

The Scanbot SDK comes with an essential camera view, additional views for extending the camera functionality, and a set of the frame handler and scanner classes that handle all the camera and scanning implementation details for you. It provides a UI for scanning guidance as well as a UI and functionality for manual and automatic shutter release.

The ScanbotCameraXView provides fully customizable camera controls and features.

Adding the feature as a dependency​

TextPatternScanner is included in Scanbot SDK package 2. Therefore, add the dependency io.scanbot:sdk-package-2 or higher in your build.gradle along with the necessary assets:

implementation("io.scanbot:sdk-package-2:$latestSdkVersion")
implementation("io.scanbot:sdk-textpattern-assets:$latestSdkVersion")

Integration​

  • ScanbotCameraXView provides fully customizable camera controls and features.
  • TextPatternScannerFrameHandler gives control over how and when frames are analyzed.
  • TextPatternScanner performs scanning extraction and validation of text data.
  • FinderOverlayView selects a specific area of the camera preview to help the user pinpoint the text location and thus improve the detection rate.

Take a look at the text-pattern-scanner example app to see how to integrate the module.

To implement the Text Pattern Scanner using dedicated Android views, you need to implement an XML layout with ScanbotCamera and FinderOverlay:

Then attach the scanner and configure the view's appearance and behavior:
