Scanning a generic document from an image with the Android Document Data Extractor Module

The Scanbot SDK Document Data Extractor is not only capable of live detection, but can also extract data from still images imported from the gallery or any other source.

The following example apps are available to see the Document Data Extractor in action and to gain a comprehensive understanding of how to integrate it into your project:

• Ready-to-Use UI example
• Classic UI live detection example
• Classic UI auto-snapping example

Adding the feature as a dependency

DocumentDataExtractor is included in Scanbot SDK package 3. Therefore, add the dependency io.scanbot:sdk-package-3 or higher in your build.gradle:

implementation("io.scanbot:sdk-package-3:$latestSdkVersion")
implementation("io.scanbot:sdk-documentdata-assets:$latestSdkVersion")

caution

Do not use multiple scanners (e.g., MRZ Scanner and Credit Card Scanner) at the same time.

Each scanner instance requires a lot of memory, GPU, and processor resources. Using multiple scanners will lead to performance issues for the entire application.

Initializing the SDK

Before use, the Scanbot SDK needs to be initialized. The following code snippet should be added to your Application class:

Processing the image

Retrieving images from the gallery

To select an image from the photo library and run detection on it, a class for an image import contract is created using the modern Android result API.

Import image Contract

To run the gallery call and get a Bitmap using ImportImageContract, the following code is used:

Import image launcher

caution

Each call to createDocumentDataExtractor() will create a new DocumentDataExtractor and initialize memory for it. If more than one import operation is expected, do not create new scanners for each operation.

Detection

The Scanbot SDK is used to detect the desired element on the imported image.
