作为一个成熟的应用, 必须要有广告. 那么, 如何优雅地开发广告呢? 需要注意一些细节.
本文提供一个简单的示例, 注释详尽, 可以学习一些页面架构和处理细节, 代码仅供参考.
需求:
具体来说, 就是
1. 显示本地存储广告图片, 点击图片, 跳转广告链接, 并提供微信分享功能.
2. 异步下载广告信息, 提高启动速度; 异步下载并保存广告和分享图片, 提高加载速度.
开发过程中, 使用了一些小技巧, 我会详细讲解注意的要点, 包括:
(1) 使用RxAndroid库, 在新线程上做异步下载广告信息.
(2) 使用Picasso库, 异步下载图片(Bitmap)并存储至本地.
(3) 使用原生Handler类, 实现计时器功能, 按秒跳转数字.
(4) 使用WebView视图, 加载广告链接, 并提供分享功能.
1. 下载广告
在欢迎页面中, 启动一个异步线程, 加载广告信息, 提高启动速度, 防止网速过慢导致切换卡顿.

在新线程(newThread)中加载, 完成后发送到主线程(mainThread). 参考.
判断网络, 在有网的时候, 加载广告信息; 在无网的时候, 直接略过.

UpdateUtils.checkDailyInfo中, 解析广告请求的返回值. 如果包含广告信息, 则存储在首选项(SharedPreference)中, 下次启动广告直接读取; 如果不包含广告信息, 则设置无数据标记, 在使用时判定无广告.
最后调用回调接口mDailyRequestCallback继续处理.

2. 存储图片
已经存储广告信息之后, 即可获得图片下载链接, 为了提高显示速度, 下载图片存储在本地. 因为下载属于网络请求, 需要异步处理, 本文使用Picasso库, 没有发明轮子.

注意: 在Picasso中, Target是和ImageView控件弱绑定, 在销毁ImageView时, 会随之销毁. 如果未提供ImageView控件, 需要手动销毁请求, 如在onPause中取消. 否则会出现下载异常. 参考.
3. 显示广告
LOGO_TIME秒, 再判断显示引导(首次启动)或显示广告.
显示广告是使用存储在首选项(SharedPreference)中的数据, 图片使用本地资源解析, 提高显示速度.

上次网络请求的存储数据, 也可能是本次网络请求的, 主要取决于在LOGO_TIME时间中, 是否下载完成启动信息, 并存储至本地.
4. 广告计时器
