Android physical key returns twice

hi @lampaa
When I started other apps using com.lampa.startapp, I pressed the Android physical back button to return to my app, but it returned twice.How can I solve it?
my code:

let sApp = startApp.set({
    "action": "ACTION_VIEW",
    "category": "CATEGORY_DEFAULT",
    "type": " text/css",
    "package": scheme,
    "uri": "taobao://" + appleUrl + "",
    "flags": ["FLAG_ACTIVITY_CLEAR_TOP", "FLAG_ACTIVITY_NEW_TASK"],
    "intentstart": "startActivity"
})
sApp.start(function(message) {
    // => OK
}, function(error) {
    /* error*/
    alert(error);
});

The normal situation should be the state of staying away
