How To Post Multi-part/form Images With String Parameter In Android

I have an API which has a payload body of type String. But has both json and image (multiparty/form) as part of the payload body. Something like this: json={jsonbody} image=@image

Solution 1:

You might need to encode the image to a String, then put that String into your request body.

If you are using volley, you can try this:

StringRequest stringRequest = newStringRequest(Request.Method.POST, URL, newResponse
            .Listener<String>() {
        @OverridepublicvoidonResponse(String response) {
            Log.d(TAG, "onResponse() called with: response = [" + response + "]");
        }
    }, newResponse.ErrorListener() {
        @OverridepublicvoidonErrorResponse(VolleyError error) {
            Log.d(TAG, "onErrorResponse() called with: error = [" + error + "]");
        }
    }) {
        @OverrideprotectedMap<String, String> getParams() throws AuthFailureError {
            Map<String, String> params = newHashMap<>();
            params.put("img", BASE64_IMG);
            return params;
        }
    };
    mRequestQueue.add(stringRequest);

Override getParams and put your params in your request.

You have to encode your image to a String, using Base64.

Solution 2:

you can use this library link is click here..

compile"cz.msebera.android:httpclient:4.4.1.2"

code for add image

protected String doInBackground(Void... params) {
            Stringresult="";
            try {
                HttpClientclient=newDefaultHttpClient();
                HttpPostpost=newHttpPost("your url");
                post.setHeader("key", Key_for_XYZ);

                MultipartEntityBuilderentityBuilder= MultipartEntityBuilder.create();
                entityBuilder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
                entityBuilder.addTextBody("id", id);
                entityBuilder.addTextBody("name", fnm);
                // file path.....
                entityBuilder.addBinaryBody("uploaded_file", destination);

                cz.msebera.android.httpclient.HttpEntityentity= entityBuilder.build();
                post.setEntity(entity);
                cz.msebera.android.httpclient.HttpResponseresponse= client.execute(post);
                cz.msebera.android.httpclient.HttpEntityhttpEntity= response.getEntity();
                result = EntityUtils.toString(httpEntity);
                Log.e("result", result);
            } catch (Exception e) {
                e.printStackTrace();
            }
            return result;
        }

// make sure you had import this packages...
