如何在应用前台制作信号推送通知警报

Question

I want my OneSignal push-notification to alert in foreground. I want notification to alert when the app is not running in phone's background. I already have my background alert working.

OneSignal.startInit(this)
                .inFocusDisplaying(OneSignal.OSInFocusDisplayOption.Notification)
                .unsubscribeWhenNotificationsAreDisabled(true)
                .init();

I expect the app to notify phones even when the app is not running in background. (That s foreground notification )

Create a class named application class

public class ApplicationClass extends MultiDexApplication {
    @Override
    public void onCreate() {
        super.onCreate();
        OneSignal.startInit(this)
                .inFocusDisplaying(OneSignal.OSInFocusDisplayOption.Notification)
                .unsubscribeWhenNotificationsAreDisabled(true).setNotificationOpenedHandler(new NotificationOpenHandler(this))
                .init();




    }
    @Override
    protected void attachBaseContext(Context context) {
        super.attachBaseContext(context);
        MultiDex.install(this);
    }

and add this class to manifest like below

<application
        android:name=".ApplicationClass"
        android:allowBackup="true"
        android:fullBackupContent="false"
        android:icon="@mipmap/ic_icon_updated"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
