Can you try this?
var myApp =new sap.m.SplitApp({
mode: sap.m.SplitAppMode.ShowHideMode,
beforeMasterOpen:function(){
this.setMode(sap.m.SplitAppMode.ShowHideMode);
},
});
masterClicked:function(oControlEvent){
myApp.toDetail("your.View");
myApp.setMode(sap.m.SplitAppMode.HideMode);
}
or
this.app = new sap.m.SplitApp("myAppID",{
afterDetailNavigate: function() {
if (sap.ui.Device.system.phone) {
this.hideMaster();
}
},
});
You can simulate android app by passing the fakeOs parameter in the url,
http://<path>/index.html/?sap-ui-xx-fakeOs=android .
