我正在使用下载管理器从我的服务器下载MP3文件。正在下载的文件保存在数据文件夹
这是它的代码。
public String createFilePath()
{
String path;
String dir = "APP_NAME";
path = Environment.getExternalStorageDirectory().getPath();
File file = new File(Environment.getExternalStorageDirectory(),dir);
if(!file.exists())
{
file.mkdir();
}
path += "/" +dir + "/";
System.out.println("-- saving path : " + path);
return path;
}
public void startDownload() {
Uri uri=Uri.parse(URLFixer.Fix(DATA.url));
System.out.println("-- download path : " + createFilePath() + FileNameGetter.getFileName(DATA..url));
DownloadManager.Request request = new Request(uri);
request.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_WIFI |DownloadManager.Request.NETWORK_MOBILE);
request.setAllowedOverRoaming(false);
request.setTitle(DATA..title);
request.setDescription(DATA.artist + " - " + DATA.album);
request.setDestinationInExternalFilesDir(activity, createFilePath(), FileNameGetter.getFileName(DATA..url));
// request.setNotificationVisibility(Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
if (Build.VERSION.SDK_INT>=Build.VERSION_CODES.HONEYCOMB) {
// request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_HIDDEN);
request.setNotificationVisibility(Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
}
lastDownload= mgr.enqueue(request);
isDownloading = true;
Toasts.pop(activity, "Download Started!!");
// v.setEnabled(false);
// findViewById(R.id.query).setEnabled(true);
}
的问题是，它应该被保存在文件夹里面“APP_NAME” SD卡，但一旦音频下载，我不能看到它这个文件夹里，当我播放音频，并检查其信息，它显示路径像thie
/sdcard/Android/data/com.X.app/files/mnt/sdcard/APP_NAME/file.mp3
由于它被保存在数据文件夹内，用户无法看到该文件。如何解决它将其移动到主SD卡即/ mnt/sdcard/APP_NAME，以便用户可以看到它。
