Save PDFs to a remote server on Android
If you already have a document saved locally and you want to commit it to a remote server once a user is done editing it, you can achieve this by uploading the contents of the document. Below is an example that uses OkHttp(opens in a new tab). We chose to use it because it’s a common dependency most projects already have, but you’re by no means required to use it if you have a different networking setup already in place:
val dataProvider = activity.requirePdfFragment().document?.documentSource?.dataProvider ?: returnval data = dataProvider.read(dataProvider.size, 0)val requestBody = data.toRequestBody("application/pdf".toMediaType())val request = Request.Builder().url("http://127.0.0.1:12345").post(requestBody).build()val client = OkHttpClient()val response = client.newCall(request).execute()final PdfDocument document = activity.requirePdfFragment().getDocument();if (document == null) return;final DataProvider dataProvider = document.getDocumentSource().getDataProvider();if (dataProvider == null) return;
final byte[] data = dataProvider.read(dataProvider.getSize(), 0);final RequestBody requestBody = RequestBody.create(data, MediaType.parse("application/pdf"));final Request request = new Request.Builder().url("http://127.0.0.1:12345").post(requestBody).build();final OkHttpClient client = new OkHttpClient();final Response response = client.newCall(request).execute();
