QR Code for launching a native application

Question

2 questions about using a QR code in an Android device: 1. Is it possible to launch a native Android application from a QR code? Maybe by some configured URI schema? 2. Another option which might be useful for me is to have a QR code scanner inside my own app. Will it be possible for me to somehow include a different app that scans QR codes inside my app? Or will I have to implement the scanning myself?

Thanks

To scan barcodes in Android by Intent, see https://github.com/zxing/zxing/wiki/Scanning-Via-Intent

To trigger an app from a QR code, yes, you need to register the app to handle the particular custom URL scheme. This is how the same app can respond to clicks on the web: https://github.com/zxing/zxing/wiki/Scanning-From-Web-Pages

Look at how it registers to handle URLs here: https://github.com/zxing/zxing/blob/master/android/AndroidManifest.xml
