禁用Android Beam和NFC

Question

I want to disable Android Beam when my NFC activity that implements CreateNdefMessageCallback is not in the foreground. Currently I use when the activity loses focus:

        if(mNFCAdapter!=null)
        {
           mNFCAdapter.disableForegroundDispatch(this);
           mNFCAdapter.setNdefPushMessage(null, this);
           mNFCAdapter.setNdefPushMessageCallback(null, this);
        }

However, every activity in my application still starts the Beam when a NFC device is discovered.

Any alternative methods?

In all activities in which you want to disable Android Beam add to onCreate() :

if(mNFCAdapter!=null) {
 mNFCAdapter.setNdefPushMessage(null, this);
 mNFCAdapter.setNdefPushMessageCallback(null, this); // optional
}
