Setup and usage

To include this library to your project add dependency in build.gradle file:

    repositories {
        jcenter()
        ...
        maven { url 'https://www.jitpack.io' }
    }
    dependencies {
        ...
        compile 'com.github.ferozbaig96:VolleySimple:1.1'
    }

Then in your Activity :

    VolleySimple.getInstance(this)
                .placeJsonObjectRequest(
                "myTag",  // tag (optional)
                url,      // url of the request
                Request.Method.GET,   // Request.Method.GET or Request.Method.POST
                params,    // parameters (optional)
                headers,   // http headers (optional)
                this);     // callback for handling response

Then make your Activity implement ServerCallback

    public class MainActivity extends AppCompatActivity implements ServerCallback {

Handle the response in your Activity

    @Override
    public void onAPIResponse(String apiTag, Object response) {
       //handle response
    }
    @Override
    public void onErrorResponse(String apiTag, VolleyError error) {
       // handle error 
    }

Additional Options

Apart from JsonObjectRequest, you can make the following requests

    // StringRequest
    VolleySimple.getInstance(this)
                .placeStringRequest(...);
    // JsonArrayRequest
    VolleySimple.getInstance(this)
                .placeJsonArrayRequest(...);

Customizations

Set timeout for requests

    VolleySimple.getInstance(this)
                .setInitialTimeoutMs(5000) // Default value = 3000 ms
                .placeJsonObjectRequest(...);

Set maximum no. of retries for requests

    VolleySimple.getInstance(this)
                .setMaxNoOfTries(4) // Default value = 2
                .placeJsonObjectRequest(...);

Tips & Tricks

GSON for handling responses

  // Create your own GSON Pojo Class. Here, SamplePojo represents a GSON Pojo
   @Override
    public void onAPIResponse(String apiTag, Object response) {
        if ("SIGN_UP_REQUEST".equals(apiTag)) {
            SamplePojo samplePojo = new Gson().fromJson(response.toString(), SamplePojo.class);
            displayname_textview.setText(samplePojo.getName);
            age_textview.setText(samplePojo.getAge());
            ...
        }
    }
