ARouter基本配置踩坑

小记：这个问题从上周就遇到了，无奈小朋友刚刚降生晚上闹睡不好，白天又要去考驾照，心碎。今天费了一个早上的时间终于成功跳转了，心情释然。

写在前面

本篇将介绍组件化过程中模块间的通信助手--ARouter的基本配置跳转以及遇到的坑

配置如下

1. 在使用路由的module的gradle中添加如下代码（base可以不添加）

android {
    defaultConfig {
    ...
    javaCompileOptions {
        annotationProcessorOptions {
        arguments = [ moduleName : project.getName() ]
        }
    }
    }
}
dependencies {//尽量引用最新版本
    compile 'com.alibaba:arouter-api:1.2.4'
    annotationProcessor 'com.alibaba:arouter-compiler:1.1.4'
    ...
}

2. 宿主app必须依赖所有使用路由的module，使用路由的module间不用相互依赖
   （如：modue_A是宿主APP，module_B和module_C之间有相互跳转的操作，则只需在宿主module_A的gradle中配置compile project(':module_B')和compile project(':module_C')）
3. 自定义Application中初始化ARouter

if (isDebug()) {           // 这两行必须写在init之前，否则这些配置在init过程中将无效
    ARouter.openLog();     // 打印日志
    ARouter.openDebug();   // 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.init(mApplication); // 尽可能早，推荐在Application中初始化

4. 路由跳转(切记路径格式)

public class Router {
    /**
     * bilibili 闪屏界面
     */
    public static final String BILIBILI_SPLASH = "/bilibili/splash";
}
ARouter.getInstance().build(BILIBILI_SPLASH).navigation();
@Route(path = BILIBILI_SPLASH)
public class SplashActivity extends Activity {
}

踩坑

深坑啊，哭的心都有了，

初始化成功了，但是遇到There is no route match the path [/bilibili/splash], in group [bilibili][ ] ，百思不得骑姐
这是因为：宿主app必须依赖所有使用路由的module，使用路由的module间不用相互依赖
