结合droidWall 网络防火墙源码

Android移动开发中比较简单的部分，可以实现记住密码，登录等功能(You can remember the password and log in)

Android下的 su 源代码结合superuser使用代码中su之后就相当于切换到root账户了供有兴趣的朋友参看

安卓的课程表，简单的课程设置，包括课程的增删改查，使得日常查询更为方便。同时提供备忘录功能，能够添加备忘事件 。软件使用图片软件进行美化。

该锁屏界面，简洁大方，可以滑动解锁，比较容易理解和改动。界面比较简单，主要是为了学习锁屏界面的使用。

说明：  类似抖音的滑动播放视频APP（含列表展示视频功能、视频录制功能）(Similar to the flick of the slide play video APP (including tiktok display video function, video recording function))

viewpager 自动轮播 带导航效果 可以设置滚动时间  方向  设置导航图标颜色背景色

Android FlowLayout-自适应高度、自动换行的标签云特效，为什么要实现这种功能呢？因为此前遇到很多标签云的显示问题，比如常见的标签样式的ViewGroup，但是很多都没有自适应高度，总不能实现想要的效果，我想自适应高度这个功能对标签云的显示很重要吧，在网上找了两个多小时，终于找到解决办法，写下这个标签云实例。

    是一个非常简单，快捷的选项卡框架

Rules::The AsyncTask instance must be created in UI thread. .execute must be invoked on the UI thread.Never call  objMyTask.onPreExecute(), objMyTask.doInBackground(), objMyTask.onProgressUpdate(),  objMyTask.onPostExecute manually.The AsyncTask can be executed only once (an exception will be thrown if a second execution is attempted.)AsyncTask have Four Main Method... onPreExecute()  doInBackground() onProgressUpdate() onPostExecute()  onPreExecute-This method is called first when you start AsyncTask using objAsync.execute().And mostly this method is use for initializing dialog(ProgressDialog,CustomDialog) and showing. doInBackground-The main purpose of AsyncTask is accomplished by this method.Any non-UI thread process is running in this method.Such as Rss Feed Reader,Image and video Uploading and Downloading.You cant handle your View in this method.Because this method is non-UI thread.While any background process is running if you want to handle UI therea are  onProgressUpdate method. after completion of process this method send result to OnPostExecute. onProgressUpdate-While backgrounding task is running ,you can handle your UI using this method .Such as status of downloading or uploading task.and this method is called from  doInBackground.Using publishProgress() you can call onProgressUpdate method to update UI while process is running. onPostExecute -This method is called after the background computation finishes.The result of background process in passed in this method as parameters.And now you can dismiss progress dialog ,to indicate that background task is completed. You can cancel AsyncTask using objAsyncTask.cancel().then you just check in doInBackground, if (isCancelled()) { break; } else {        //continue... } See this Image For more Clear.

* 1. 识别率更高，支付宝，等软件的识别效率更高。 * 2. 复杂的环境下，依然能保持很高的识别率。 * 3. 能支持更多token的识别，通过编码可以传送所有字符。 * 4. 通过定制可以实现相同字符的连续传递,比如“234456”。 * 5. 支持自动纠错功能，在有3个以内字符解码出错的情况下可以自动纠正。 * 6. 程序运行效率非常高，可以用于智能手机，功能手机，嵌入式设备，PC，平板等嵌入式系统上。 * 7. 声波的频率声音和音量可定制。
