Android Zxing Intentintegrator

I've written the following code that works fine if you decide to scan a QR code (using zxing) and store it in private storage but in case you decide to cancel scanning, it crashes

Solution 1:

You need to check the resultCode. If the scan is canceled there is no information about the barcode value. With the resultCode you can check if the operation was successful or not.

if(resultCode == RESULT_OK) {
    // scan successful
} else {
    // no result
}
