问题描述
在我的Android应用我下载过的应用程序购买的视频从城市飞艇。
当我点击我的应用程序中的特定按钮下载得到启动。在这样的情况下，在下载充分完成后欲使按钮成为不可见来获得一个通知或报警。我怎么能知道该视频已完全下载？
有没有一块code我可以写在下载完成后在Android中得到通知？
解决方案
私人无效startDownload（）{
字符串URL =这里写您的网址;
新DownloadFileAsync（）执行（URL）;
}
@覆盖
受保护的对话框onCreateDialog（INT ID）{
开关（ID）{
案例DIALOG_DOWNLOAD_PROGRESS：
mProgressDialog =新ProgressDialog（本）;
// mProgressDialog.setIcon（R.drawable.icon）;
mProgressDialog.setIcon（R.drawable.tab_icon_pitchforkfm）;
mProgressDialog.setTitle（下载文件...
+ GlobalVariable.Getstrpath（）的toString（））。
mProgressDialog.setProgressStyle（ProgressDialog.STYLE_HORIZONTAL）;
mProgressDialog.setCancelable（真正的）;
mProgressDialog.show（）;
返回mProgressDialog;
默认：
返回null;

在preExecute保护无效（）{
super.on preExecute（）;
的ShowDialog（DIALOG_DOWNLOAD_PROGRESS）;
}

保护字符串doInBackground（字符串...为arg0）{
// TODO自动生成方法存根。

网址URL =新的URL（GlobalVariable.Getstr（））;
HttpURLConnection的C =（HttpURLConnection类）url.openConnection（）;

//字符串文件名=workTest.mp3;
字符串文件名=请将test.mp3;
文件OUTPUTFILE =新的文件（文件，文件名）;
FileOutputStream中FOS =新的FileOutputStream（OUTPUTFILE）;
InputStream的是= c.getInputStream（）;
byte []的缓冲区=新的字节[1024];
总长= 0;
而（（计数= is.read（缓冲液））！= - 1）{
共有+ =计数;
publishProgress（+（int）的（（总* 100）/ lenghtOfFile））;
// fos.write（缓冲液，0，LEN1）;
fos.write（缓冲，0，计数）;
}
fos.close（）;

In my Android application I am downloading a video through an application purchase from Urban Airship.
When I click a particular button in my application the downloading gets started. In such a case, after the download completes fully I want to get a notification or alert so that the button becomes invisible. How can I know that the video has been downloaded completely?
Is there any piece of code I could write to be notified when a download finishes in Android?
