Scanning via Intent

Scanning via Intent

The simplest way to integrate barcode scanning into your app is to invoke the Barcode Scanner via an intent.

import com.vuzix.sdk.barcode.ScannerIntent; 
import com.vuzix.sdk.barcode.ScanResult2; 
private static final int REQUEST_CODE_SCAN = 0; 
Intent scannerIntent = new Intent(ScannerIntent.ACTION);
startActivityForResult(scannerIntent, REQUEST_CODE_SCAN);

The scan result will be returned to you in onActivityResult():

@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
	switch (requestCode) {
		case REQUEST_CODE_SCAN:
		if (resultCode == Activity.RESULT_OK) {
			ScanResult2 scanResult = data.getParcelableExtra(ScannerIntent.RESULT_EXTRA_SCAN_RESULT2);
			// do something with scan result
		}
		return:
	}
	super.onActivityResult(requestCode, resultCode, data);
}

For more information on barcode scanning by intent, including intent extras that are available, refer to the JavaDoc for the ScannerIntent class.
