Question

Hello I am wondering how do you have an android app that can go online and retrieve a custom file type and then store it on the phone in a readable space for the application? Also sense I’m already posting how would you have your android application read the said file?

Thank you for you time.

Nothing specific to Android. Do it how you do in Java.

   // Create a URL for the desired file
   URL url = new URL(URL_LOCATION);
   // Open an InputStream to read the resource
   InputStream is = url.openStream();

   // Use this InputStream to read your file

Here is how you can use this InputStream to save the file on sd card by using OutputStream.

         try {
                File root = Environment.getExternalStorageDirectory();

                String localFilePath = root.getPath() + "/yourFileName";



                FileOutputStream fos = new FileOutputStream(localFilePath, false);

                OutputStream os = new BufferedOutputStream(fos);



                byte[] buffer = new byte[1024];

                int byteRead = 0;



                while ((byteRead = is.read(buffer)) != -1) {

                        os.write(buffer, 0, byteRead);

                }

                fos.close();

        } catch (Exception e) {

                e.printStackTrace();

        }
