基于Android Volley的网络请求工具。

####一、说明 Android network manager based on Android Volley, JSON, XML, Map, RequestMap(with file) support.
AndroidVolley，Android Volley核心库及扩展工程。
AndroidVolleySample，网络请求工具示例工程。
Release，AndroidVolley jar包。

####二、Volley基本处理流程：
1、应用初始化Volley。
2、Volley创建一个RequestQueue、NetworkDispatcher组及Network。
3、RequestQueue即一个Request队列，RequestQueue会创建一个ExecutorDelivery。
4、NetworkDispatcher实质是Thread，从RequestQueue中取Request，通过Network加以执行。
5、Network负责网络请求处理，具体过程交给HttpStack处理。
6、HttpStack分HttpURLConnection(SDK_INT>=9)与HttpClient与两种方式。
7、ExecutorDelivery负责处理请求结果，并与主线程进行交互。
8、Volley在上述2-7的基础上增加了Cache等附加处理环节。

####三、网络请求工具
在AndroidVolley基础上扩展了com.android.http包，增加了ByteArrayRequest及RequestManager，方便JSON、XML、Map<String, Sting>()、及RequestMap<String, File>()的网络请求。

#####1.初始化RequestManager public class VolleyApplication extends Application { @Override public void onCreate() { super.onCreate(); RequestManager.getInstance().init(this);//初始化工具 }

	@Override
	public void onTerminate() {
		super.onTerminate();
	}
}

#####2.使用RequestManager public class MainActivity extends Activity {

	private static final String OUT_FILE = "upload.txt";

	private static final String OUT_DATA = "sadf464764sdf3ds1f3adsf789213557r12-34912-482130487321gjsaldfalfu2390q3rtheslafkhsdafhreasof";

	private static final String POST_URL = "http://allthelucky.ap01.aws.af.cm/memoServer";

	private static final String POST_JSON = "{\"action\":\"test\", \"info\":\"hello world\"}";

	private static final String GET_URL = "https://raw.githubusercontent.com/panxw/android-volley-manager/master/test.txt";

	private static final String UPLOAD_URL = "http://www.splashpadmobile.com/upload.php";

	private LoadControler mLoadControler = null;

	private ImageView mImageView;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		this.mImageView = (ImageView) findViewById(R.id.imageView1);

		this.testPost();
		this.testGet();
		this.testFileUpload();
		this.testImageLoader();
	}

	private void testPost() {
		mLoadControler = RequestManager.getInstance().post(POST_URL, POST_JSON, requestListener, 0);
	}

	private void testGet() {
		mLoadControler = RequestManager.getInstance().get(GET_URL, requestListener, 1);
	}

	private void testFileUpload() {
		MainActivity.prepareFile(this);

		RequestMap params = new RequestMap();
		File uploadFile = new File(this.getFilesDir(), OUT_FILE);
		params.put("uploadedfile", uploadFile);
		params.put("share", "1");

		mLoadControler = RequestManager.getInstance().post(UPLOAD_URL, params, requestListener, 2);
	}

	private void testImageLoader() {
		NetworkApplication.getImageLoader().get("http://www.baidu.com/img/bdlogo.png", new ImageListener() {

			@Override
			public void onErrorResponse(VolleyError error) {
				System.out.println("Image onErrorResponse");
			}

			@Override
			public void onResponse(ImageContainer response, boolean isImmediate) {
				System.out.println("Image onResponse");
				if (response != null && response.getBitmap() != null) {
					mImageView.setImageBitmap(response.getBitmap());
				}
			}
		});
	}
	
	private RequestListener requestListener = new RequestListener() {
		@Override
		public void onSuccess(String response, String url, int actionId) {
			System.out.println("actionId:" + actionId + ", OnSucess!\n" + response);
		}

		@Override
		public void onError(String errorMsg, String url, int actionId) {
			System.out.println("actionId:" + actionId + ", onError!\n" + errorMsg);
		}

		@Override
		public void onRequest() {
			System.out.println("request send...");
		}
	};

	@Override
	public void onBackPressed() {
		super.onBackPressed();
		if (mLoadControler != null) {
			mLoadControler.cancel();
		}
	}

	private static void prepareFile(Context context) {
		FileOutputStream fos = null;
		try {
			fos = context.openFileOutput(OUT_FILE, Context.MODE_PRIVATE);
			try {
				fos.write(OUT_DATA.getBytes());
			} catch (IOException e) {
				e.printStackTrace();
			}
		} catch (FileNotFoundException e) {
			e.printStackTrace();
		} finally {
			if (fos != null) {
				try {
					fos.close();
				} catch (IOException e) {
					e.printStackTrace();
				}
			}
		}
	}
