Google drive api on IONIC

Hi there.
I tried to implement google drive API follow this page :

I started with:

 gapi.load('client:auth2', () => {
            return gapi.client.init({
                apiKey: API_KEY,
                clientId: CLIENT_ID,
                discoveryDocs: DISCOVERY_DOCS,
                scope: SCOPES,
            }).then(() => {                   
                this.googleAuth = gapi.auth2.getAuthInstance();

then i signed by:

        prompt: 'consent'
    }).then(function() => {
        // use the api

Every thing ok on ionic browser.
But when i run it on my android device, the status bar always load. I can’t get access token.

Anyone else know how to solve this problem. I 'll be very appreciate with your help.
