I need an alternative option to HttpClient in Android to send data to PHP as it is no longer supported

Question

Currently I'm using HttpClient, HttpPost to send data to my PHP server from an Android app but all those methods were deprecated in API 22 and removed in API 23, so what are the alternative options to it?

I searched everywhere but I didn't find anything.

Answer 1

I've also encountered with this problem to solve that I've made my own class. Which based on java.net, and supports up to android's API 24 please check it out: HttpRequest.java

Using this class you can easily:

1. Send Http GET request
2. Send Http POST request
3. Send Http PUT request
4. Send Http DELETE
5. Send request without extra data params & check response HTTP status code
6. Add custom HTTP Headers to request (using varargs)
7. Add data params as String query to request
8. Add data params as HashMap {key=value}
9. Accept Response as String
10. Accept Response as JSONObject
11. Accept response as byte [] Array of bytes (useful for files)

and any combination of those - just with one single line of code)

Here are a few examples:

//Consider next request: 
HttpRequest req=new HttpRequest("http://host:port/path");

Example 1:

//prepare Http Post request and send to "http://host:port/path" with data params name=Bubu and age=29, return true - if worked
req.prepare(HttpRequest.Method.POST).withData("name=Bubu&age=29").send();

Example 2:

// prepare http get request,  send to "http://host:port/path" and read server's response as String 
req.prepare().sendAndReadString();

Example 3:

// prepare Http Post request and send to "http://host:port/path" with data params name=Bubu and age=29 and read server's response as JSONObject 
HashMap<String, String>params=new HashMap<>();
params.put("name", "Groot"); 
params.put("age", "29");
req.prepare(HttpRequest.Method.POST).withData(params).sendAndReadJSON();

Example 4:

//send Http Post request to "http://url.com/b.c" in background  using AsyncTask
new AsyncTask<Void, Void, String>(){
        protected String doInBackground(Void[] params) {
            String response="";
            try {
                response=new HttpRequest("http://url.com/b.c").prepare(HttpRequest.Method.POST).sendAndReadString();
            } catch (Exception e) {
                response=e.getMessage();
            }
            return response;
        }
        protected void onPostExecute(String result) {
            //do something with response
        }
    }.execute(); 

Example 5:

//Send Http PUT request to: "http://some.url" with request header:
String json="{\"name\":\"Deadpool\",\"age\":40}";//JSON that we need to send
String url="http://some.url";//URL address where we need to send it 
HttpRequest req=new HttpRequest(url);//HttpRequest to url: "http://some.url"
req.withHeaders("Content-Type: application/json");//add request header: "Content-Type: application/json"
req.prepare(HttpRequest.Method.PUT);//Set HttpRequest method as PUT
req.withData(json);//Add json data to request body
JSONObject res=req.sendAndReadJSON();//Accept response as JSONObject

Example 6:

//Equivalent to previous example, but in a shorter way (using methods chaining):
String json="{\"name\":\"Deadpool\",\"age\":40}";//JSON that we need to send
String url="http://some.url";//URL address where we need to send it 
//Shortcut for example 5 complex request sending & reading response in one (chained) line
JSONObject res=new HttpRequest(url).withHeaders("Content-Type: application/json").prepare(HttpRequest.Method.PUT).withData(json).sendAndReadJSON();

Example 7:

//Downloading file
byte [] file = new HttpRequest("http://some.file.url").prepare().sendAndReadBytes();
FileOutputStream fos = new FileOutputStream("smile.png");
fos.write(file);
fos.close();
