How do I send a file in Android from a mobile device to server using http?

Question

In android, how do I send a file(data) from a mobile device to server using http.

Answer 1

the most effective method is to use android-async-http

You can use this code to upload a file:

// gather your request parameters
File myFile = new File("/path/to/file.png");
RequestParams params = new RequestParams();
try {
    params.put("profile_picture", myFile);
} catch(FileNotFoundException e) {}

// send request
AsyncHttpClient client = new AsyncHttpClient();
client.post(url, params, new AsyncHttpResponseHandler() {
    @Override
    public void onSuccess(int statusCode, Header[] headers, byte[] bytes) {
        // handle success response
    }

    @Override
    public void onFailure(int statusCode, Header[] headers, byte[] bytes, Throwable throwable) {
        // handle failure response
    }
});

Note that you can put this code directly into your main Activity, no need to create a background Task explicitly. AsyncHttp will take care of that for you!
