I am using a barcodescanner library.
There is a sample code for a "SimpleScannerActivity":
public class SimpleScannerActivity extends Activity implements ZXingScannerView.ResultHandler {
private ZXingScannerView mScannerView;
@Override
public void onCreate(Bundle state) {
super.onCreate(state);
mScannerView = new ZXingScannerView(this); // Programmatically initialize the scanner view
setContentView(mScannerView); // Set the scanner view as the content view
}
@Override
public void onResume() {
super.onResume();
mScannerView.setResultHandler(this); // Register ourselves as a handler for scan results.
mScannerView.startCamera(); // Start camera on resume
}
@Override
public void onPause() {
super.onPause();
mScannerView.stopCamera(); // Stop camera on pause
}
@Override
public void handleResult(Result rawResult) {
// Do something with the result here
Log.v(TAG, rawResult.getText()); // Prints scan results
Log.v(TAG, rawResult.getBarcodeFormat().toString()); // Prints the scan format (qrcode, pdf417 etc.)
// If you would like to resume scanning, call this method below:
mScannerView.resumeCameraPreview(this);
}
}
I have copied that class and everything seems working. But only the method that reruns the onResume() method does not work with the following error message:
mScannerView.resumeCameraPreview(this); Cannot resolve method ‘resumeCameraPreview(com.ads.adstimer.fragment.Registration.Slides,FullScannerActivity)’
I really do not understand what I am doing wrong and how I can fix that since I just have copied that code...
Finally the solution is easy:
change the dependency version from 1.8.3:
compile 'me.dm7.barcodescanner:zxing:1.8.3'
to 1.8.4:
compile 'me.dm7.barcodescanner:zxing:1.8.4'
