Answer 1

1) Add ChildBrowser Phongap Plugin for android in your app.
2) Your login page add this code
$("#btn_log_facebook").on("click", function(event){
if(event.handled !== true) {
var fb = FBConnect.install();
var client_id = your_client_id;
var redir_url = your_redir_url;
fb.connect(client_id,redir_url,"touch");
event.handled = true;
}
return false;
});
3) Create fb_connect.js file
function FBConnect()
{
if(window.plugins.childBrowser == null)
{
ChildBrowser.install();
}
}
FBConnect.prototype.connect = function(client_id,redirect_uri,display)
{
this.client_id = client_id;
this.redirect_uri = redirect_uri;
var authorize_url = "https://graph.facebook.com/oauth/authorize?";
authorize_url += "client_id=" + client_id;
authorize_url += "&redirect_uri=" + redirect_uri;
authorize_url += "&display="+ ( display ? display : "touch" );
authorize_url += "&type=user_agent";
var ref = window.open(authorize_url, 'random_string', 'location=no');
ref.addEventListener('loadstart', function(event) {
//console.log(event.type + ' - ' + event.url);
} );
ref.addEventListener('loadstop', function(event) {
var access_token = event.url.split("access_token=")[1];
var error_reason = event.url.split("error_reason=")[1];
if(access_token != undefined){
access_token = access_token.split("&")[0];
loginWithFacebookUserInfo(access_token);
setTimeout(function() {
ref.close();
}, 5000);
}
if(error_reason != undefined){
window.location.href = "register.html";
setTimeout(function() {
ref.close();
}, 5000);
}
//console.log(event.url); alert(event.type + ' - ' + event.url);
} );
ref.addEventListener('exit', function(event) {
//console.log(event.type);
} );
}
