To download a file in Android over HTTPS, you can use the following steps:
- Add the necessary permissions to your AndroidManifest.xml file:
1
|
<uses-permission android:name="android.permission.INTERNET" /> |
- Create a new AsyncTask class to handle the file download process. Here is an example of how you can do this:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 |
import android.os.AsyncTask;
import java.io.InputStream;
import java.io.FileOutputStream;
import java.net.URL;
import javax.net.ssl.HttpsURLConnection;
public class DownloadFileTask extends AsyncTask<String, Void, Void> {
@Override
protected Void doInBackground(String... urls) {
try {
URL url = new URL(urls[0]);
HttpsURLConnection connection = (HttpsURLConnection) url.openConnection();
connection.connect();
InputStream input = connection.getInputStream();
FileOutputStream output = new FileOutputStream("your_file_name_here");
byte[] buffer = new byte[1024];
int bytesRead;
while ((bytesRead = input.read(buffer)) != -1) {
output.write(buffer, 0, bytesRead);
}
output.close();
input.close();
connection.disconnect();
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
}
|
- Execute the AsyncTask to start the file download process in your Activity:
1
|
new DownloadFileTask().execute("https://www.example.com/file_to_download.pdf");
|
Make sure to replace "https://www.example.com/file_to_download.pdf" with the actual URL of the file you want to download.
- Make sure to handle appropriate error handling, such as checking for network connectivity, permissions, file writing errors, etc., based on your specific requirements.
By following these steps, you should be able to download a file in Android over HTTPS successfully.
