Below is the code for downloading files from my server. I write the download file to the root directory of the sd card, but it works well!
package com.downloader;
import java.io.File;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.net.HttpURLConnection;
import java.net.URL;
import android.os.Environment;
import android.util.Log;
public class Downloader {
public void DownloadFile(String fileURL, String fileName) {
try {
File root = Environment.getExternalStorageDirectory();
URL u = new URL(fileURL);
HttpURLConnection c = (HttpURLConnection) u.openConnection();
c.setRequestMethod("GET");
c.setDoOutput(true);
c.connect();
FileOutputStream f = new FileOutputStream(new File(root, fileName));
InputStream in = c.getInputStream();
byte[] buffer = new byte[1024];
int len1 = 0;
while ((len1 = in.read(buffer)) > 0) {
f.write(buffer, 0, len1);
}
f.close();
} } catch (Exception e) {
Log.d("Downloader", e.getMessage());
}
}
}
But when you use Environment.getExternalStorageDirectory(); the file is always written to the root folder, that is, /mnt/sdcard Is it possible to write a file in a specific folder? For example, /mnt/sdcard/myapp/downloads
android java android-sdcard http download
File sdCard = Environment.getExternalStorageDirectory();
File dir = new File (sdCard.getAbsolutePath() + "/dir1/dir2");
dir.mkdirs();
File file = new File(dir, "filename");
FileOutputStream f = new FileOutputStream(file);
It's possible.
