Download

Maven:

com.koushikdutta.async

androidasync

(insert latest version)

Gradle:

dependencies {

compile 'com.koushikdutta.async:androidasync:2.+'

}

将url下载为一个字符串

// url is the URL to download.

AsyncHttpClient.getDefaultInstance().getString(url, new AsyncHttpClient.StringCallback() {

// Callback is invoked with any exceptions/errors, and the result, if available.

@Override

public void onCompleted(Exception e, AsyncHttpResponse response, String result) {

if (e != null) {

e.printStackTrace();

return;

}

System.out.println("I got a string: " + result);

}

});

从url下载JSON

// url is the URL to download.

AsyncHttpClient.getDefaultInstance().getJSONObject(url, new AsyncHttpClient.JSONObjectCallback() {

// Callback is invoked with any exceptions/errors, and the result, if available.

@Override

public void onCompleted(Exception e, AsyncHttpResponse response, JSONObject result) {

if (e != null) {

e.printStackTrace();

return;

}

System.out.println("I got a JSONObject: " + result);

}

});

JSON Arrays

// url is the URL to download.

AsyncHttpClient.getDefaultInstance().getJSONArray(url, new AsyncHttpClient.JSONArrayCallback() {

// Callback is invoked with any exceptions/errors, and the result, if available.

@Override

public void onCompleted(Exception e, AsyncHttpResponse response, JSONArray result) {

if (e != null) {

e.printStackTrace();

return;

}

System.out.println("I got a JSONArray: " + result);

}

});

将url下载为文件

AsyncHttpClient.getDefaultInstance().getFile(url, filename, new AsyncHttpClient.FileCallback() {

@Override

public void onCompleted(Exception e, AsyncHttpResponse response, File result) {

if (e != null) {

e.printStackTrace();

return;

}

System.out.println("my file is available at: " + result.getAbsolutePath());

}

});
