Android项目源码基于传感器的温度计开发是android应用上的温度计，是通过传感器来感知外面的温度。应该说这个应用太强大了，用到传感器技术，并能时时更新。项目中代码层次分明，大部分方法都加了详细的注释。对于想学习传感器的开发人员来说，简直是福音。（项目采用GBK编码，是studio工程）。(Android project source sensor based on the development of the thermometer is a thermometer on the Android application, it is through the sensor to sense the temperature outside. It should be said that this application is too powerful, the use of sensor technology, and can always update. Items in the code level, most of the methods have added a detailed notes. For developers who want to learn sensor, it is the gospel. (the project uses the GBK code, is the studio project).)

由于项目需要在Android方法中调用JS实现相应的功能，在学习WebView组件时，参照李刚的《疯狂Android讲义》，但是它讲的太简单了，只有JS调用Android方法，却没有提及Androi如何调用JS方法，所以上网学习并简单的写了一个实例

1.FileCache　文件缓存操作类 2.ImageLoader图片加载类，首先从内存中加载，如果内存中不存在，则从本地加载，如果本地也没有，则从网络上下载。 3.MemoryCache内存缓存操作类 4.ShopGoodsDetailGalleryAdapter适配器 5.MainActivity程序运行的入口

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.
