Question

I want to make an Android app by using ZXing. Can anyone tell me how to use the core library, or anyone know how to use the core library to build a barcode scanner?

Answer 1

You need to call Zxing intent in your Activity and relax.

First add code to invoke the Intent:

IntentIntegrator integrator = new IntentIntegrator(yourActivity);
integrator.initiateScan();

Second, add this to your Activity to handle the result:

public void onActivityResult(int requestCode, int resultCode, Intent intent) {
  IntentResult scanResult = IntentIntegrator.parseActivityResult(requestCode, resultCode, intent);
  if (scanResult != null) {
    // handle scan result
  }
  // else continue with any other code you need in the method
  ...
}

Invest your time to go through wiki page of Zxing.They have explained it very nicely.

Here is sample application demonstrating how to call Zxing intent.
