library

1.UI:

• TabbedCoordinatorLayout --- (From vitovalov) : TabbedCoordinatorLayout is a Sample project demostrating the usage of TabLayout (ViewPager with Tabs) inside of CollapsingToolbarLayout all together in CoordinatorLayout. [基于Android Design Support Library兼容控件实现视差Tab效果].

  

• BlurZoomGallery --- (From fafaldo) : Extended CoordinatorLayout, that helps creating background galleries. [继承自 CoordinatorLayout,实现背景缩放与模糊效果].

  

• Lab-Android-DesignLibrary --- (From nuuneoi) : A full tutorial on how to use Android Design Support Library. (60 mins). [基于Android Design Support Library兼容控件实现的Simple].

  

• LargeImage --- (From LuckyJayce) : Loading big Image,Maximum support 10000ps x 10000ps. [Android 加载大图 可以高清显示10000*10000像素的图片].

  

2.Logic：

• enroscar-async --- (From stanfy & Tag is AsyncTask) : Makes it easy to put your asynchronous operations behind Android's Loader. [使用注解异步线程调度].

  

    //1.Describe an asynchronous operation.
    class Foo {
      @Load Async<String> loadGreeting(final String name) {
        return Tools.async(new Callable<String>() {
          public String call() {
            try { Thread.sleep(1000); } catch (InterruptedException ignored) { }
            return "Hello " + name;
          }
        });
      }
    } 
  
    //2.Use it
    // this an object that provides operations
    Foo foo = new Foo();
  
    // prepare the operator
    // FooOperator is a generated class
    FooOperator operator = FooOperator.build()
        .withinActivity(activity)
        .operations(foo)
        .get();
  
    // subscribing
    operator.when().loadGreetingIsFinished()
        .doOnResult(new Action<String>() {
          @Override
          public void act(final String greeting) {
            Log.i("Async", "Greeting loaded: " + greeting);
          }
        });
  
    // starting
    operator.loadGreeting();
  
    // cancelling
    operator.cancelLoadGreeting(); 
  

• feather --- (From zsoltherpai & Tag is Annotation):Lightweight dependency injection for Java and Android (JSR-330). [Java和android轻量级的依赖注入].

  

    public class A {
        @Inject
        public A(B b) {
            // ...
        }
    }
  
    public class B {
        @Inject
        public B(C c, D d) {
            // ...
        }
    }
  
    public class C {}
  
    @Singleton
    public class D {
        // something expensive or other reasons for being singleton
    }
  

• secure-preferences --- (From scottyab & Tag is Encryption): Android Shared preference wrapper than encrypts the values of Shared Preferences. It's not bullet proof security but rather a quick win for incrementally making your android app more secure. [给Shared Preferences存储的数据进行AES的加密].

  

  

    SecurePreferences securePrefs = new SecurePreferences(context, "userpassword","my_user_prefs.xml");
    securePrefs.handlePasswordChange("newPassword", context);
  

• java-aes-crypto --- (From tozny & Tag is Encryption):A simple Android class for encrypting & decrypting strings, aiming to avoid the classic mistakes that most such classes suffer from. [使用AES加解密].

  

    //1.Generate new key
    AesCbcWithIntegrity.SecretKeys keys = AesCbcWithIntegrity.generateKey();
  
    //2.Encrypt
    AesCbcWithIntegrity.CipherTextIvMac cipherTextIvMac = AesCbcWithIntegrity.encrypt("some test", keys);
       //store or send to server
       String ciphertextString = cipherTextIvMac.toString();
  
    //3.Decrypt
    String plainText = AesCbcWithIntegrity.decryptString(cipherTextIvMac, keys);
  

• AESCrypt-Android --- (From scottyab & Tag is Encryption):Simple API to perform AES encryption on Android. This is the Android counterpart to the AESCrypt library Ruby and Obj-C (with the same defaults) created by Gurpartap Singh. [使用AES加解密].

  

    //Encrypt
    String password = "password";
    String message = "hello world"; 
    try {
        String encryptedMsg = AESCrypt.encrypt(password, message);
    }catch (GeneralSecurityException e){
      //handle error
    }    
  
    //Decrypt
    String password = "password";
    String encryptedMsg = "2B22cS3UC5s35WBihLBo8w==";
    try {
        String messageAfterDecrypt = AESCrypt.decrypt(password, encryptedMsg);
    }catch (GeneralSecurityException e){
     //handle error - could be due to incorrect password or tampered encryptedMsg
    }
  

3.Architecture:

• powermock --- (From jayway) : PowerMock is a Java framework that allows you to unit test code normally regarded as untestable. [超强的测试框架].
