Instructor Notes

Before completing the quiz above, make sure you have added the necessary code to configure periodic syncs.

The code in this video will create the logic to, when you start Sunshine, check if an account has been created for Sunshine and if not, create a new account and configure a periodic sync to start.

Instructions

FetchWeatherTask and the SunshineService are now just older, unused classes which do the same thing that the SunshineSyncAdapter class is doing now; remove them. Clean up the AndroidManifest.xml and remove SunshineService and the AlarmReciever from the xml.

问题

我们常常需要在Android工程里面放一些比较敏感的信息，比如某些三方服务的API Key之类的信息。但是设置到工程中每次手工修改代码又很麻烦，于是我查看了一些资料，实现了在local.properties这个文件中保存敏感信息。同时因为local.properties这个文件默认被gitignore了，相对来说还是比较安全。

操作方法

在工程根目录的local.properties里面填入你想保存的敏感信息

比如MyTMDBApiKey＝xxxx

#Intro

Let's get started.

This is a quick guide to Kotlin programming language. The previous part of this guide is here
