I. Feature

  1. Supports direct parsing of standard URLs for jumps and automatic injection of parameters into target pages
  2. Support for multi-module
  3. Support for interceptor
  4. Support for dependency injection
  5. InstantRun support
  6. MultiDex support
  7. Mappings are grouped by group, multi-level management, on-demand initialization
  8. Supports users to specify global demotion and local demotion strategies
  9. Activity, interceptor and service can be automatically registered to the framework
  10. Support multiple ways to configure transition animation
  11. Support for fragment
  12. Full kotlin support (Look at Other#2)
  13. Generate route doc support
  14. Provide IDE plugin for quick navigation to target class
  15. Support Incremental annotation processing
  16. Support register route meta dynamic.

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 ``` gradle android { defaultConfig { ... javaCompileOptions { annotationProcessorOptions { arguments = [AROUTERMODULENAME: project.getName()] } } } }

    dependencies { // Replace with the latest version compile '' annotationProcessor '' ... } // 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 ``` java // 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{*;} -keep public class{;} -keep class * implements{;}

    If you use the byType method to obtain Service, add the following rules to protect the interface:

    -keep interface * implements

    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

  6. Using the custom gradle plugin to autoload the routing table ```gradle apply plugin: ''

    buildscript { repositories { mavenCentral() }

    dependencies {
        // Replace with the latest version
        classpath ""

    } ```

    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
    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 ``` java // 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();

    } ```

    AndroidManifest.xml ``` xml <!-- Scheme -->

    <category android:name="android.intent.category.DEFAULT"></category>
    <category android:name="android.intent.category.BROWSABLE"></category>


  2. Parse the parameters in the URL ``` java // 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

    protected void onCreate(Bundle savedInstanceState) {
    // 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 json2Object(String text, Class clazz) { return JSON.parseObject(text, clazz); }

    @Override public String object2Json(Object instance) { return JSON.toJSONString(instance); }

    } ```

  3. Declaration Interceptor (Intercept jump process, AOP) ``` java // 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 ``` java // U can get the result of a single jump ARouter.getInstance().build("/test/1").navigation(this, new NavigationCallback() { @Override public void onFound(Postcard postcard) { ... }

    public void onLost(Postcard postcard) {

    }); ```

  5. Custom global demotion strategy ``` java // Implement the DegradeService interface @Route(path = "/xxx/xxx") public class DegradeServiceImpl implements DegradeService { @Override public void onLost(Context context, Postcard postcard) { // do something. }

    public void init(Context context) {


    } ```

  6. Decoupled by dependency injection : Service management -- Exposure services ``` java // 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 {

    public String sayHello(String name) {
        return "hello, " + name;

    @Override public void init(Context context) {


    } ```

  7. Decoupled by dependency injection : Service management -- Discovery service ``` java 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();


    } ```

  8. Pretreatment Service ``` java @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 }

    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() {
            public void loadInto(Map atlas) {
                atlas.put("/dynamic/activity",      // path
                        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 ``` java // 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.slideinbottom, R.anim.slideoutbottom) .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 ``` java // 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"]

VI. Other

  1. Old version of gradle plugin configuration ``` gradle apply plugin: ''
