[英]How to save file on SD card by using download manger in Android?
我在我的應用程序中面臨兩個問題。
1-我正在使用Android DownloadManager
下載在線文件,但它將所有文件下載到系統目錄,例如使用Download
目錄
request.setDestinationInExternalPublicDir(Environment.DIRECTORY_PICTURES, "fileName");
現在我想將文件下載到我自己的目錄中說“新建文件夾”。 如何實施呢? 請在這方面幫助我,我會非常感激。
2-如何檢查SD卡是否可用?
使用這種方式:這里Dhaval_files是我的文件夾名稱
public void file_download(String uRl) {
File direct = new File(Environment.getExternalStorageDirectory()
+ "/dhaval_files");
if (!direct.exists()) {
direct.mkdirs();
}
DownloadManager mgr = (DownloadManager) this.getSystemService(Context.DOWNLOAD_SERVICE);
Uri downloadUri = Uri.parse(uRl);
DownloadManager.Request request = new DownloadManager.Request(
downloadUri);
request.setAllowedNetworkTypes(
DownloadManager.Request.NETWORK_WIFI
| DownloadManager.Request.NETWORK_MOBILE)
.setAllowedOverRoaming(false).setTitle("Demo")
.setDescription("Something useful. No, really.")
.setDestinationInExternalPublicDir("/dhaval_files", "test.jpg");
mgr.enqueue(request);
}
1)
Uri downloadUri = Uri.parse(DOWNLOAD_FILE);
DownloadManager.Request request = new DownloadManager.Request(downloadUri);
request.setDescription("Downloading a file");
long id = downloadManager.enqueue(request.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_WIFI |DownloadManager.Request.NETWORK_MOBILE)
.setAllowedOverRoaming(false)
.setTitle("File Downloading...")
.setDescription("Image File Download")
.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, "cm.png"));
2)
Boolean isSDPresent = android.os.Environment.getExternalStorageState().equals(android.os.Environment.MEDIA_MOUNTED);
if(isSDPresent)
{
// yes download code
}
else
{
// No sdcard
}
