getWindow 在genymotion andriod虚拟机上运行我的应用程序时。下面是简短的错误屏幕截图

import { Component, OnInit } from "@angular/core";
import {Page} from "ui/page";
import * as app from "tns-core-modules/application";

@Component({
    selector: "Home",
    moduleId: module.id,
    templateUrl: "./home.component.html",
    styleUrls: ["./home.component.scss"]
})
export class HomeComponent implements OnInit {

    constructor(page: Page) {
        page.actionBarHidden = true;
        this.statusBar('hide');
    }

    ngOnInit(): void {

        // Init your component properties here.
    }

    statusBar(action: string){
        var activity = app.android.startActivity;
        //activity.runOnUiThread(function(){
        var win = activity.getWindow();
        if(action === 'hide'){
            win.addFlags(app.android.nativeApp.view.WindowManager.LayoutParams.FLAG_FULLSCREEN);
        } else if(action === 'show'){
            win.clearFlags(app.android.nativeApp.view.WindowManager.LayoutParams.FLAG_FULLSCREEN);
        }
    }
}

请帮我解决这个问题。谢谢。
