Agregar flujo a bordo Tutoriales para desarrolladores de SAP

Haga clic derecho en el paquete com.sap.flows y seleccione Nuevo> Clase Java.

Especifique el nombre de la nueva clase MyApplication.

Sustituye el código por la clase. MyApplication.java con el código de abajo.

package com.sap.flows;

import android.app.Application;

import com.sap.cloud.mobile.foundation.authentication.AppLifecycleCallbackHandler;

public class MyApplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        registerActivityLifecycleCallbacks(AppLifecycleCallbackHandler.getInstance());
    }
}

Esta clase habilita el diálogo de autenticación básica para acceder a la actividad principal, de modo que se pueda visualizar.

Sa manifests/AndroidManifest.xml archivo, agregue la entrada a continuación y cambie allowBackup falso.

android:name=".MyApplication"

Modifique el proyecto para usar JDK 1.8 para origen y destino navegando a Archivo> Estructura del proyecto o haciendo clic en el icono de la barra de herramientas.

Cree un nuevo archivo de recursos de diseño en el res/layout carpeta llamada splash_screen.xml. Sustituya el siguiente código por su contenido. La pantalla de bienvenida se mostrará hasta que se complete el flujo de retorno o de a bordo.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:gravity="center">

    <ImageView android:id="@+id/splashscreen" android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@mipmap/ic_launcher_round"/>

    <TextView android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="Wiz App"
        android:textAlignment="center"/>
</LinearLayout>
