I want to wrap these source codes to create additional libraries for B4A to serve the purpose of scientific research on GNSS satellite positioning technology in Vietnam
I only have a small budget of 30$, please help me
Thank you very much.

and B4i

You will not be able to use this java codes with b4i as b4i does not use java-language.

For the NTRIP-Client i can´t help. I wrote one in the past for a Customer. But as it was a paid Job i can not give out the Library.

Bạn sẽ không thể sử dụng mã Java này với b4i vì b4i không sử dụng ngôn ngữ Java.

Đối với NTRIP-Client, tôi không thể giúp được. Tôi đã từng viết một cái cho một Khách hàng. Nhưng vì đó là Công việc được trả lương nên tôi không thể cung cấp Thư viện.

PS. i have url "https://14.238.1.125:2101", when i open it on chrome browser it will automatically let me download the file "download" to my computer, could you please help me code in B4A to get this file

You can download it using OkHttpUtils2 library by yourself, here is the Code Snippet

The server speaks http 0.9, which is a headerless response. I have no idea if it's possible to use that out of the box with the current http libraries we have. It should be very possible to just grab it using standard network communication though, you just have to craft the GET command, which is basic stuff.

For reference, here's how to get the data using curl:

Bash:

sandman@mothership:~ curl http://14.238.1.125:2101/
curl: (1) Received HTTP/0.9 when not allowed
sandman@mothership:~ curl --http0.9 --verbose http://14.238.1.125:2101/

Máy chủ nói http 0.9, đây là phản hồi không có tiêu đề. Tôi không biết liệu có thể sử dụng nó ngay với các thư viện http hiện tại mà chúng ta có hay không. Tuy nhiên, có thể chỉ cần lấy nó bằng giao tiếp mạng tiêu chuẩn, bạn chỉ cần tạo lệnh GET, đây là lệnh cơ bản.

Để tham khảo, đây là cách lấy dữ liệu bằng curl:

Bash:

sandman@mothership:~ curl http://14.238.1.125:2101/
curl: (1) Đã nhận HTTP/0.9 khi không được phép
sandman@mothership:~ curl --http0.9 --verbose http://14.238.1.125:2101/
