ARouter版本：
implementation.alibaba:arouter-api:1.4.0'
annotationProcessor'com.alibaba:arouter-compiler:1.2.1'

场景：
集成完毕 app running
调用ARouter.getInstance().build(url).navigation；
后无法跳转界面 而使用startActivity能够正常跳转界面

如果实现了IInterceptor 接口即使不在path中添加extras属性仍会走入拦截器中
(在此之前一直以为需要手动调用extras属性才会启用拦截)

@Route(path = RouterUrl.STUDENT_CHOOSE_LOGIN_METHOD,extras = RouterExtras.EXTRA_COMMON)
public class ChooseLoginMethodAct extends BaseActivity {

所以需要在实现类中手动调用
callback.onContinue(postcard);

@Interceptor(priority = 1)
public class LoginInterceptor implements IInterceptor {
    /**
     * The operation of this tollgate.
     *
     * @param postcard
     *         meta
     * @param callback
     *         callback
     */
    @Override
    public void process(Postcard postcard, InterceptorCallback callback) {
        // 是否需要登录
//        if (RouterExtras.EXTRA_LOGIN == postcard.getExtra()) {
//            // 是否已经登录
//            if (UserLogic.isLand()) {
//                callback.onContinue(postcard);
//            } else {
//                ARouter.getInstance().build(RouterUrl.USER_LOGIN).navigation();
//                callback.onInterrupt(null);
//            }
//        } else {
//            callback.onContinue(postcard);
//        }

        callback.onContinue(postcard);
    }
