We believe this is a potential for a security or malicious action bug and will not be implementing it in Chrome any longer. See https://code.google.com/p/chromium/issues/detail?id=169204#c27 for more details.

There is a solution, you can construct a special "intent" url that the user can invoke.

The basic syntax for an intent based URI is as follows:

“intent:”
    HOST/URI-path “;”  // Optional
        “#Intent;”
        package=[string];
        action=[string];
        category=[string];
        component=[string];
                    scheme=[string];
    “;end”

Parsing details available in the Android source.

To launch the Zxing barcode scanner app you can encode your href as follows intent://scan/#Intent;scheme=zxing;package=com.google.zxing.client.android;end in an href on the anchor as follows Take a qr code

Extracted from : https://code.google.com/p/zxing/source/browse/trunk/android/AndroidManifest.xml#97

The android manifest defines the scheme to be “zxing”, the package to be “com.google.zxing.client.android” and the host data to be “scan” When the user clicks on this link they will taken straight to the app if they already have it installed, or if not directly to the play store.
