ARouter初始化

在lib_base中创建MyApplication

public class MyApplication extends Application {
    /**
     * 上下文
     */
    private static MyApplication instance;

    @Override
    public void onCreate() {
        super.onCreate();
        instance = this;
        initRouter(this);
    }

    public static Context getInstance() {
        return instance;
    }

    private void initRouter(MyApplication mApplication) {
        // 这两行必须写在init之前，否则这些配置在init过程中将无效
        if (UIUtils.isApkInDebug(instance)) {
            //打印日志
            ARouter.openLog();
            //开启调试模式(如果在InstantRun模式下运行，必须开启调试模式！
            //线上版本需要关闭,否则有安全风险)
            ARouter.openDebug();
        }
        // 尽可能早，推荐在Application中初始化
        ARouter.init(mApplication);

    }
}

 /**
     * 判断当前应用是否是debug状态
     */

    public static boolean isApkInDebug(Context context) {
        try {
            ApplicationInfo info = context.getApplicationInfo();
            return (info.flags & ApplicationInfo.FLAG_DEBUGGABLE) != 0;
        } catch (Exception e) {
            return false;
        }
    }

这里要注意：如果你在debug模式下进行调试代码，ARouter.openDebug();一定要调用，否则ARouter会出现无效情况。

首页的搭建

使用ARouter来获取到各个模块的Fragment

package tsou.cn.lib_base.utils;

/**
 * Created by Administrator on 2017/12/4 0004.
 */

public class RouteUtils {
    //获得home模块fragment
    public static final String Home_Fragment_Main = "/home/main";
    //获得chat模块fragment
    public static final String Chat_Fragment_Main = "/chat/main";
    //获得Recom模块fragment
    public static final String Recom_Fragment_Main = "/recom/main";
    //获得Me模块fragment
    public static final String Me_Fragment_Main = "/me/main";
    //跳转到登录页面
    public static final String Me_Login = "/me/main/login";
    //跳转到eventBus数据接收页面
    public static final String Me_EventBus = "/me/main/EventBus";
    //跳转到TextOne数据接收页面
    public static final String Me_TextOne = "/me/main/TextOne";
    //跳转到Test公用页面
    public static final String Me_Test = "/me/main/Test";
    //路由拦截
    public static final String Me_Test2 = "/me/main/Test2";
    //跳转到webview页面
    public static final String Me_WebView = "/me/main/WebView";

    //跳转到依赖注入页面
    public static final String Me_Inject = "/me/main/Inject";
    /**
     * 依赖注入使用，注意：必须实现SerializationService进行注册，
     */
    public static final String Home_Json_Service = "/huangxiaoguo/json";

    //跳转ForResult
    public static final String Chat_ForResult = "/chat/main/ForResult";
    //模块间服务调用，调用chat模块的接口
    public static final String Service_Chat = "/chat/service";
    //路由拦截
    public static final String Chat_Interceptor = "/chat/main/Interceptor";

    /**
     * 专门的分组，这里就叫做needLogin组，凡是在这个组下的，都会进行登录操作
     */
    public static final String NeedLogin_Test3 = "/needLogin/main/Test3";

}

代码中有注释，切很简单，不会出现什么毛病！如果有小毛病，就clean一下解决.
