java.net.SocketTimeoutException thrown only on some Android devices

Question

I am trying to upload a JPEG image file from an Android device. I am using the square/okhttp library for creating a request. I am facing this issue on the Lenovo Yoga tablet, that when I am trying to upload the image, it gets the below exception. But when I run the same code on Samsung Galaxy Tab 10", it all works fine and the image gets uploaded successfully.

The camera captures the image and stores it at /storage/emulated/0/ from where the app will pick up the image and try to upload it. I have a service running in the background that does the upload.

final MediaType MEDIA_TYPE_IMAGE_JPEG = MediaType.parse("image/jpeg");

        File file = new File(path);
        Request request = new Request.Builder()
                .url(baseUrl)
                .addHeader("timestamp", map.get("timestamp"))
                .addHeader("Content-Type", map.get("Content-Type"))
                .post(RequestBody.create(MEDIA_TYPE_IMAGE_JPEG, file))
                .build();

        OkHttpClient client = new OkHttpClient();
        Response response = client.newCall(request).execute();

Exception:

Answer 1

You have to increase the read/write timeout on the server end. A temporary workaround for Android would be increasing the default timeout for OkHttp3 client:

OkHttpClient client = new OkHttpClient.Builder()
        .connectTimeout(60, TimeUnit.SECONDS)
        .writeTimeout(120, TimeUnit.SECONDS)
        .readTimeout(60, TimeUnit.SECONDS)
        .build();
