    II. Classic Case

    1. Forward from external URLs to internal pages, and parsing parameters
    2. Jump and decoupling between multi-module
    3. Intercept jump process, handle login, statistics and other logic
    4. Cross-module communication, decouple components by IoC

    III. Configuration

    1. Adding dependencies and configurations

      android {
          defaultConfig {
              ...
              javaCompileOptions {
                  annotationProcessorOptions {
                      arguments = [AROUTER_MODULE_NAME: project.getName()]
                  }
              }
          }
      }
      
      dependencies {
          // Replace with the latest version
          compile 'com.alibaba:arouter-api:?'
          annotationProcessor 'com.alibaba:arouter-compiler:?'
          ...
      }
      // Old version of gradle plugin (< 2.2), You can use apt plugin, look at 'Other#1'
      // Kotlin configuration reference 'Other#2'
    2. Add annotations

      // Add annotations on pages that support routing (required)
      // The path here needs to pay attention to need at least two levels : /xx/xx
      @Route(path = "/test/activity")
      public class YourActivity extend Activity {
          ...
      }
    3. Initialize the SDK

      if (isDebug()) {           // These two lines must be written before init, otherwise these configurations will be invalid in the init process
          ARouter.openLog();     // Print log
          ARouter.openDebug();   // Turn on debugging mode (If you are running in InstantRun mode, you must turn on debug mode! Online version needs to be closed, otherwise there is a security risk)
      }
      ARouter.init(mApplication); // As early as possible, it is recommended to initialize in the Application
    4. Initiate the routing

      // 1. Simple jump within application (Jump via URL in 'Advanced usage')
      ARouter.getInstance().build("/test/activity").navigation();
      
      // 2. Jump with parameters
      ARouter.getInstance().build("/test/1")
                  .withLong("key1", 666L)
                  .withString("key3", "888")
                  .withObject("key4", new Test("Jack", "Rose"))
                  .navigation();
    5. Add confusing rules (If Proguard is turn on)

      -keep public class com.alibaba.android.arouter.routes.**{*;}
      -keep public class com.alibaba.android.arouter.facade.**{*;}
      -keep class * implements com.alibaba.android.arouter.facade.template.ISyringe{*;}
      
      # If you use the byType method to obtain Service, add the following rules to protect the interface:
      -keep interface * implements com.alibaba.android.arouter.facade.template.IProvider
      
      # If single-type injection is used, that is, no interface is defined to implement IProvider, the following rules need to be added to protect the implementation
      # -keep class * implements com.alibaba.android.arouter.facade.template.IProvider
    6. Using the custom gradle plugin to autoload the routing table

      apply plugin: 'com.alibaba.arouter'
      
      buildscript {
          repositories {
              mavenCentral()
          }
      
          dependencies {
              // Replace with the latest version
              classpath "com.alibaba:arouter-register:?"
          }
      }

      Optional, use the registration plugin provided by the ARouter to automatically load the routing table(power by AutoRegister). By default, the ARouter will scanned the dex files . Performing an auto-registration via the gradle plugin can shorten the initialization time , it should be noted that the plugin must be used with api above 1.3.0!

    7. use ide plugin for quick navigation to target class (Optional)

      Search for ARouter Helper in the Android Studio plugin market, or directly download the arouter-idea-plugin zip installation package listed in the Latest version above the documentation, after installation plugin without any settings, U can find an icon at the beginning of the jump code. (navigation) click the icon to jump to the target class that identifies the path in the code.

    IV. Advanced usage

    1. Jump via URL

      // Create a new Activity for monitoring Scheme events, and then directly pass url to ARouter
      public class SchemeFilterActivity extends Activity {
          @Override
          protected void onCreate(Bundle savedInstanceState) {
              super.onCreate(savedInstanceState);
      
              Uri uri = getIntent().getData();
              ARouter.getInstance().build(uri).navigation();
              finish();
          }
      }

      AndroidManifest.xml

      <activity android:name=".activity.SchemeFilterActivity">
          <!-- Scheme -->
          <intent-filter>
              <data
                  android:host="m.aliyun.com"
                  android:scheme="arouter"/>
      
              <action android:name="android.intent.action.VIEW"/>
      
              <category android:name="android.intent.category.DEFAULT"/>
              <category android:name="android.intent.category.BROWSABLE"/>
          </intent-filter>
      </activity>
    2. Parse the parameters in the URL

      // Declare a field for each parameter and annotate it with @Autowired
      @Route(path = "/test/activity")
      public class Test1Activity extends Activity {
          @Autowired
          public String name;
          @Autowired
          int age;
          @Autowired(name = "girl") // Map different parameters in the URL by name
          boolean boy;
          @Autowired
          TestObj obj;    // Support for parsing custom objects, using json pass in URL
      
          @Override
          protected void onCreate(Bundle savedInstanceState) {
              super.onCreate(savedInstanceState);
              ARouter.getInstance().inject(this);
      
              // ARouter will automatically set value of fields
              Log.d("param", name + age + boy);
          }
      }
      
      // If you need to pass a custom object, Create a new class(Not the custom object class),implement the SerializationService, And use the @Route annotation annotation, E.g:
      @Route(path = "/yourservicegroupname/json")
      public class JsonServiceImpl implements SerializationService {
          @Override
          public void init(Context context) {
      
          }
      
          @Override
          public <T> T json2Object(String text, Class<T> clazz) {
              return JSON.parseObject(text, clazz);
          }
      
          @Override
          public String object2Json(Object instance) {
              return JSON.toJSONString(instance);
          }
      }
    3. Declaration Interceptor (Intercept jump process, AOP)

      // A more classic application is to handle login events during a jump so that there is no need to repeat the login check on the target page.
      // Interceptors will be executed between jumps, multiple interceptors will be executed in order of priority
      @Interceptor(priority = 8, name = "test interceptor")
      public class TestInterceptor implements IInterceptor {
          @Override
          public void process(Postcard postcard, InterceptorCallback callback) {
              ...
              // No problem! hand over control to the framework
              callback.onContinue(postcard);  
              
              // Interrupt routing process
              // callback.onInterrupt(new RuntimeException("Something exception"));      
      
              // The above two types need to call at least one of them, otherwise it will not continue routing
          }
      
          @Override
          public void init(Context context) {
              // Interceptor initialization, this method will be called when sdk is initialized, it will only be called once
          }
      }
    4. Processing jump results

      // U can get the result of a single jump
      ARouter.getInstance().build("/test/1").navigation(this, new NavigationCallback() {
          @Override
          public void onFound(Postcard postcard) {
          ...
          }
      
          @Override
          public void onLost(Postcard postcard) {
          ...
          }
      });
    5. Custom global demotion strategy

      // Implement the DegradeService interface
      @Route(path = "/xxx/xxx")
      public class DegradeServiceImpl implements DegradeService {
          @Override
          public void onLost(Context context, Postcard postcard) {
              // do something.
          }
      
          @Override
          public void init(Context context) {
      
          }
      }
    6. Decoupled by dependency injection : Service management -- Exposure services

      // Declaration interface, other components get the service instance through the interface
      public interface HelloService extends IProvider {
          String sayHello(String name);
      }
      
      @Route(path = "/yourservicegroupname/hello", name = "test service")
      public class HelloServiceImpl implements HelloService {
      
          @Override
          public String sayHello(String name) {
              return "hello, " + name;
          }
      
          @Override
          public void init(Context context) {
      
          }
      }
    7. Decoupled by dependency injection : Service management -- Discovery service

      public class Test {
          @Autowired
          HelloService helloService;
      
          @Autowired(name = "/yourservicegroupname/hello")
          HelloService helloService2;
      
          HelloService helloService3;
      
          HelloService helloService4;
      
          public Test() {
              ARouter.getInstance().inject(this);
          }
      
          public void testService() {
              // 1. Use Dependency Injection to discover services, annotate fields with annotations
              helloService.sayHello("Vergil");
              helloService2.sayHello("Vergil");
      
              // 2. Discovering services using dependency lookup, the following two methods are byName and byType
              helloService3 = ARouter.getInstance().navigation(HelloService.class);
              helloService4 = (HelloService) ARouter.getInstance().build("/yourservicegroupname/hello").navigation();
              helloService3.sayHello("Vergil");
              helloService4.sayHello("Vergil");
          }
      }
    8. Pretreatment Service

      @Route(path = "/xxx/xxx")
      public class PretreatmentServiceImpl implements PretreatmentService {
          @Override
          public boolean onPretreatment(Context context, Postcard postcard) {
              // Do something before the navigation, if you need to handle the navigation yourself, the method returns false
          }
      
          @Override
          public void init(Context context) {
      
          }
      }
    9. Dynamic register route meta Applicable to apps with plug-in architectures or some scenarios where routing information needs to be dynamically registered,Dynamic registration can be achieved through the interface provided by ARouter, The target page and service need not be marked with @Route annotation,Only the routing information of the same group can be registered in the same batch

          ARouter.getInstance().addRouteGroup(new IRouteGroup() {
              @Override
              public void loadInto(Map<String, RouteMeta> atlas) {
                  atlas.put("/dynamic/activity",      // path
                      RouteMeta.build(
                          RouteType.ACTIVITY,         // Route type
                          TestDynamicActivity.class,  // Target class
                          "/dynamic/activity",        // Path
                          "dynamic",                  // Group
                          0,                          // not need
                          0                           // Extra tag, Used to mark page feature
                      )
                  );
              }
          });

    V. More features

    1. Other settings in initialization

      ARouter.openLog(); // Open log
      ARouter.openDebug(); // When using InstantRun, you need to open this switch and turn it off after going online. Otherwise, there is a security risk.
      ARouter.printStackTrace(); // Print thread stack when printing logs
    2. API description

      // Build a standard route request
      ARouter.getInstance().build("/home/main").navigation();
      
      // Build a standard route request, via URI
      Uri uri;
      ARouter.getInstance().build(uri).navigation();
      
      // Build a standard route request, startActivityForResult
      // The first parameter must be Activity and the second parameter is RequestCode
      ARouter.getInstance().build("/home/main", "ap").navigation(this, 5);
      
      // Pass Bundle directly
      Bundle params = new Bundle();
      ARouter.getInstance()
          .build("/home/main")
          .with(params)
          .navigation();
      
      // Set Flag
      ARouter.getInstance()
          .build("/home/main")
          .withFlags();
          .navigation();
      
      // For fragment
      Fragment fragment = (Fragment) ARouter.getInstance().build("/test/fragment").navigation();
                          
      // transfer the object 
      ARouter.getInstance()
          .withObject("key", new TestObj("Jack", "Rose"))
          .navigation();
      
      // Think the interface is not enough, you can directly set parameter into Bundle
      ARouter.getInstance()
              .build("/home/main")
              .getExtra();
      
      // Transition animation (regular mode)
      ARouter.getInstance()
          .build("/test/activity2")
          .withTransition(R.anim.slide_in_bottom, R.anim.slide_out_bottom)
          .navigation(this);
      
      // Transition animation (API16+)
      ActivityOptionsCompat compat = ActivityOptionsCompat.
          makeScaleUpAnimation(v, v.getWidth() / 2, v.getHeight() / 2, 0, 0);
      
      // ps. makeSceneTransitionAnimation, When using shared elements, you need to pass in the current Activity in the navigation method
      
      ARouter.getInstance()
          .build("/test/activity2")
          .withOptionsCompat(compat)
          .navigation();
              
      // Use green channel (skip all interceptors)
      ARouter.getInstance().build("/home/main").greenChannel().navigation();
      
      // Use your own log tool to print logs
      ARouter.setLogger();
      
      // Use your custom thread pool
      ARouter.setExecutor();
    3. Get the original URI

      String uriStr = getIntent().getStringExtra(ARouter.RAW_URI);
    4. Rewrite URL

      // Implement the PathReplaceService interface
      @Route(path = "/xxx/xxx")
      public class PathReplaceServiceImpl implements PathReplaceService {
          /**
          * For normal path.
          *
          * @param path raw path
          */
          String forString(String path) {
              // Custom logic
              return path;
          }
      
      /**
          * For uri type.
          *
          * @param uri raw uri
          */
          Uri forUri(Uri uri) {
              // Custom logic
              return url;
          }
      }
    5. Generate router doc

      // Edit build.gradle, add option 'AROUTER_GENERATE_DOC = enable'
      // Doc file : build/generated/source/apt/(debug or release)/com/alibaba/android/arouter/docs/arouter-map-of-${moduleName}.json
      android {
          defaultConfig {
              ...
              javaCompileOptions {
                  annotationProcessorOptions {
                      arguments = [AROUTER_MODULE_NAME: project.getName(), AROUTER_GENERATE_DOC: "enable"]
                  }
              }
          }
      }
