Android ZBar QR Code Scanner - How to read every QR Code

I currently implemented ZBar QR Code Scanner Library into my own app. But, so far, I am just able to read a QR Code that leads to a website. What should I do if I want to scan a QR Code that leads you to dial a phone number or text messages? How do I make my app read any QR Code?

Solution

  • The content of the QR code should be irrelevant -- it's just text. It might happen to contain a URL, but that doesn't change the format of the QR code.

    int result = imageScanner.scanImage(image);

// Nonzero means a result was found
if (result != 0) {

    // Typical only one symbol unless multiple codes were found
    // in the scanned image
    for (Symbol symbol : imageScanner.getResults()) {

        // .getData() gives the string content of the QR code
        String qrCodeContent = symbol.getData();
    }
}
