Good morning,
we have Android Xamarin application with Barcode Scanner API. On every Activity we have InitScanner method OnResume event and DeinitScanner method on OnPause event.
public void InitScanner(bool enableScannerOnStartup) { if (emdkManager != null) { if (barcodeManager == null) { try { barcodeManager = (BarcodeManager) emdkManager.GetInstance(EMDKManager.FEATURE_TYPE.Barcode); scanner = barcodeManager.GetDevice(BarcodeManager.DeviceIdentifier.Default); if (scanner != null) { scanner.Data += scanner_Data; scanner.Enable(); } } catch (ScannerException e) { //LOG } catch (Exception e) { //LOG } } } }public void DeinitScanner() { if (emdkManager != null) { if (scanner != null) { try { scanner.Data -= scanner_Data; scanner.Status -= scanner_Status; scanner.Disable(); } catch (ScannerException e) { //LOG } } if (barcodeManager != null) { emdkManager.Release(EMDKManager.FEATURE_TYPE.Barcode); } barcodeManager = null; scanner = null; } }
InitScanner and DeinitScanner is called for every Activity. We have problem with speed (Init takes aproximately 4 seconds - on every StartActivity). What is the best solution how to speed up application (BarcodeAPI, DataWedge profile, create scanner singleton)?
Thank you for advice.
Barcode API - very slow |
