In Android API 29 and above you can use the below code to store files, images and videos to external storage.
//First, if your picking your file using "android.media.action.IMAGE_CAPTURE"
then store that file in applications private Path(getExternalFilesDir()) as below.
File destination = new File(context.getExternalFilesDir(Environment.DIRECTORY_PICTURES), fileName);
//Then use content provider to get access to Media-store as below.
ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.TITLE, fileName);
values.put(MediaStore.Images.Media.DISPLAY_NAME, fileName);
//if you want specific mime type, specify your mime type here. otherwise leave it blank, it will take default file mime type
values.put(MediaStore.Images.Media.MIME_TYPE, "MimeType");
values.put(MediaStore.Images.Media.DATE_ADDED, System.currentTimeMillis() / 1000);
values.put(MediaStore.Images.Media.DATE_TAKEN, System.currentTimeMillis());
values.put(MediaStore.Images.Media.RELATIVE_PATH, "Pictures/" + "path"); // specify
storage path
// insert to media-store using content provider, it will return URI.
Uri uri = cxt.getContentResolver().insert(MediaStore.Files.getContentUri("external"), values);
//Use that URI to open the file.
ParcelFileDescriptor descriptor = context.getContentResolver().openFileDescriptor(uri,"w"); //"w" specify's write mode
FileDescriptor fileDescriptor = descriptor.getFileDescriptor();
// read file from private path.
InputStream dataInputStream = cxt.openFileInput(privatePath_file_path);
//write file into out file-stream.
OutputStream output = new FileOutputStream(fileDescriptor);
byte[] buf = new byte[1024];
int bytesRead;
while ((bytesRead = dataInputStream.read(buf)) > 0)
{
output.write(buf, 0, bytesRead);
}
datanputStream.close();
output.close();
}
