About Dynamsoft Barcode Reader Android Samples
Before you start viewing the samples, the following concepts may help you understand how to get started with Dynamsoft Barcode Reader.
License
You need a valid license to unlock the full feature of Dynamsoft Barcode Reader. Otherwise, the barcode results will be encoded and the coordinates of barcode location results are offset.
- The samples on GitHub are provided with time-limited free trial, which require network connection to work.
- You can request for a 30-day trial license via the Customer Portal. Offline trial license is also available by contacting us.
- If you download the sample along with the Installation Package, the 30-day trial license is already included in the sample code.
Scan Mode
Here we define 3 different scan modes:
- One-off scanning: Scan barcode(s) from the video streaming and stop scanning after barcode results are output.
- Continuous scanning: Scan barcode(s) from the video streaming and output barcode results continuously.
- Image decoding: Read barcode(s) from an image, an image in the memory or a bitmap by triggering image decoding method(s).
For the majority of our samples, one-off scanning and continuous scanning from the video streaming are using Dynamsoft Camera Enhancer (DCE) to capture the video streaming. For the features and APIs of DCE please view DCE online documents. You can also use a third party library like CameraX to capture the video streaming.
Performance
In the samples, we demonstrate the performance settings from 3 different aspects: Speed, Read Rate and Accuracy. The parameter configurations are generally speed-friendly, read-rate-friendly and accuracy-friendly settings but might not be the best settings for your usage scenario. The performance sample can help you get a basic understanding of the Dynamsoft Barcode Reader parameters. Please feel free to contact us for further support on optimizing the parameters.
