Dev Tools App

The Dev Tools App is a powerful android development tool that can help you improve efficiency greatly, It can be used to view the latest open source projects, view activity history, view manifest, decompile, color picker, extract apk or so, view app info, open or close the options in the developer options quickly, and more.

You can download it from DevTools@Google Play.

一. 缓存类

主要特性：(1).使用简单 (2).轻松获取及预取取新图片 (3).包含二级缓存 (4).可选择多种缓存算法(FIFO、LIFO、LRU、MRU、LFU、MFU等13种)或自定义缓存算法 (5).可方便的保存及初始化恢复数据 (6).省流量性能佳(有且仅有一个线程获取图片) (7).支持http请求header设置及不同类型网络处理(8).可根据系统配置初始化缓存 (9).扩展性强 (10).支持等待队列 (11)包含map的大多数接口。

1. 图片缓存

使用见：图片缓存的使用
适用：获取图片较多且图片使用频繁的应用，包含二级缓存，如新浪微博、twitter、微信头像、美丽说、蘑菇街、花瓣、淘宝等等。效果图如下：
ImageCahe

2. 图片SD卡缓存

使用见：图片SD卡缓存的使用
适用：应用中获取图片较多且图片较大的情况。需要二级缓存及ListView或GridView图片加载推荐使用上面的ImageCache。效果图如下：
ImageSDCardCache

3. 网络缓存

使用见：Android网络缓存
适用：网络获取内容不大的应用，尤其是api接口数据，如新浪微博、twitter的timeline、微信公众账号发送的内容等等。效果图如下：
HttpCache

4. 预取数据缓存

使用见：预取数据缓存
缓存类关系图如下：其中HttpCache为后续计划的http缓存 Image Cache

二. 公用的view

1. 下拉刷新及滚动到底部加载更多的Listview

使用: 下拉刷新及滚动到底部加载更多listview的使用
实现原理: http://trinea.iteye.com/blog/1562281。效果图如下：
DropDownListView

2. 滑动一页(一个Item)的Gallery

使用及实现原理：滑动一页(一个Item)的Gallery的使用。效果图如下：
ViewPager1 ViewPager2

3. 滑动到底部或顶部响应的ScrollView

使用及实现原理: 滚动到底部或顶部响应的ScrollView使用。效果图如下：
ScrollView

三. 工具类

具体介绍可见：Android常用工具类
目前包括HttpUtils、DownloadManagerPro、ShellUtils、PackageUtils、PreferencesUtils、JSONUtils、FileUtils、ResourceUtils、StringUtils、ParcelUtils、RandomUtils、ArrayUtils、ImageUtils、ListUtils、MapUtils、ObjectUtils、SerializeUtils、SystemUtils、TimeUtils。

1. Android系统下载管理DownloadManager使用

使用示例：Android系统下载管理DownloadManager功能介绍及使用示例
功能扩展：Android下载管理DownloadManager功能扩展和bug修改 效果图如下：
downloadManagerDemo

2. Android APK root权限静默安装

使用示例：Android APK root权限静默安装

3. Android root权限

直接调用ShellUtils.execCommand方法

4. 图片工具类

(1)Drawable、Bitmap、byte数组相互转换; (2)根据url获得InputStream、Drawable、Bitmap
更多工具类介绍见Android常用工具类

  • Utils Should have 2 version

    Utils Should have 2 version

    Hello,

    great work. indeed it would be great if we have 2 versions of Utils.

    1. Separate Utils which can be used individually without dependent on another Utils.
    2. Dependent Utils [the current version]

    i hope it makes clear. because sometimes a developer wants just one Utils in their project and they are ended up importing many files.

    研究了一下imagecache的code。demo app的用法是： IMAGE_SD_CACHE.get(imageUrlList.get(position), holder.imageView);

    一个建议，这个接口是不是不应该关心view呢，包括callback的接口。因为在callback的时候view和url的关系可能变化，或者view已经不可见了。如果用的人把ImageSDCardCache用成singleton的了，那么是不是可能造成view的内存泄漏呢。

    可能我的理解有误，供大家讨论吧

  • HttpResponse getCacheControlMaxAge 返回值用int过小

    HttpResponse getCacheControlMaxAge 返回值用int过小

    比如缓存一个月的话 maxAge = 30 * 24 * 60 * 60 = 2592000 然后 maxAge * 1000 就超过了int的范围变成了负数，然后expireTime就永远在当前时间之前了.缓存就永远失败了.

    https://github.com/Trinea/android-common/blob/master/src/cn/trinea/android/common/entity/HttpResponse.java

    232 行改成long应该就可以了吧? 否则267行那里就会导致 maxAge * 1000 变成 -1702967296
