| View release history

DownZ is an HTTP library that boosts networking in Android apps and makes it significantly easier and faster.

DownZ offers the following benefits:

  • Handles HTTP requests.
  • Transparent memory response caching of JSON and Images with support for request prioritization.
  • Cancel a request of image upload or download at any given time.
  • Images in memory cache are auto removed if not used for a long time.
  • Ease of customization, for example, cancel request and clear cache.
  • Strong requisition that makes it easy to effectively manage UI with data being fetched asynchronously from the network.

DownZ excels at handling HTTP requests.It comes with built-in support for images, JSON and Xml. By providing built-in support for the features you require, DownZ frees you from writing tons of code and finally allows you to concentrate on the logic that is specific to your app.

How do I use DownZ?

Make Standard Request

…  DownZ

 .from(mContext) //context

  .load(DownZ.Method.GET, “http://yoururl.com”)

 .asBitmap()  //asJsonArray() or asJsonObject() or asXml() can be used depending on need

 .setCallback(new HttpListener<Bitmap>() {

  @Override

  public void onRequest() {

 //On Beginning of request

}

@Override

  public void onResponse(Bitmap data) {

 if(data != null){

  // do something

 
}

  
}

@Override

  public void onError() {

 //do something when there is an error

}

@Override

  public void onCancel() {

 //do something when request cancelled

}

 
}
);
 

Pass Header or Request Parameters (Optional)


 ... DownZ

 .from(MainActivity.this)

 .load(DownZ.Method.GET,mUrl)

 .setHeaderParameter("key","value")

 .setRequestParameter("key1","value1")

 .setRequestParameter("key2","value2")

 .asBitmap()

 .setCallback(new HttpListener<Bitmap>() {

  @Override

  public void onRequest() {

}

@Override

  public void onResponse(Bitmap bitmap) {

if(bitmap != null){

  //do something

}

  
}

@Override

  public void onError() {

}

@Override

  public void onCancel() {

}

 
}
);
 

Enable Cache

... public class SomeActivity extends AppCompatActivity {

  ...
  CacheManager<JSONArray> cacheManager; // we can use JSONObject, Bitmap as generic type
  @Override
  protected void onCreate(Bundle savedInstanceState) {

...

cacheManager=new CacheManager<>(40*1024*1024);
 // 40mb
  
}
  public void OnRequestMade(View v){

DownZ

 .from(this)

 .load(DownZ.Method.GET, "http://www.url.com")

 .asJsonArray()

 .setCacheManager(cacheManager)

 .setCallback(new HttpListener<JSONArray>() {

  @Override

  public void onRequest() {

//fired when request begins

  
}

@Override

  public void onResponse(JSONArray data) {

if(data!=null){

 // do some stuff here

}

  
}

@Override

  public void onError() {

}

@Override

  public void onCancel() {

}

 
}
);
 
}
 
}
 

Load Image into ImageView

... public class SomeActivity extends AppCompatActivity {

  ...
  CacheManager<Bitmap> cacheManager;

@Override
  protected void onCreate(Bundle savedInstanceState) {

...

cacheManager=new CacheManager<>(40*1024*1024);
 // 40mb

imageview = (ImageView) findViewById(R.id.image_profile);

imageview.setDrawingCacheEnabled(true);
 //can be used if Image has to be shared afterwards

imageview.buildDrawingCache();

...

  
}
 //event to make request public void btnLoadImageClicked(View v){

  DownZ

 .from(this)

 .load(DownZ.Method.GET, "http://www.url.com/image.jpg")

 .asBitmap()

 .setCacheManager(cacheManager)

 .setCallback(new HttpListener<Bitmap>() {

  @Override

  public void onRequest() {

//fired when request begin
 
}

@Override

  public void onResponse(Bitmap data) {

if(data!=null){

 // do some stuff here

 imageview.setImageBitmap(data);

}

  
}

@Override

  public void onError() {

}

@Override

  public void onCancel() {

}

 
}
);
 
}
  
}
 

Removing from Cache

 ...  public class SomeActivity extends AppCompatActivity {

  ...
  CacheManager<Bitmap> cacheManager;

@Override
  protected void onCreate(Bundle savedInstanceState) {

...

String mUrl = "http://yoururl.com/image.png";

cacheManager=new CacheManager<>(40*1024*1024);
 // 40mb

imageview = (ImageView) findViewById(R.id.image_profile);

imageview.setDrawingCacheEnabled(true);
 //can be used if Image has to be shared afterwards

imageview.buildDrawingCache();

...

  
}
 //event to clear item from cache public void btntoClearCache(View v){

cacheManager.removeDataFromCache(mUrl);
 
}
 
}
