*App 离线 SDK 下载地址：[https://nativesupport.dcloud.net.cn/AppDocs/download/android][https_nativesupport.dcloud.net.cn_AppDocs_download_android]*

--------------------

App 离线 SDK 下载解压后，使用 `Android Studio` 打开`UniPlugin-Hello-AS` 工程，删除自带的三个模块:

*  `uniplugin_component`
 *  `uniplugin_module`
 *  `uniplugin_richalert`

--------------------

1.  添加模块，将需要调用的 jar 包拷贝到新增模块的 libs文件夹下，并添加依赖：  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L1RfUmF5_size_16_color_FFFFFF_t_70_pic_center]
2.  编写 js 与 jar包相互调用的中间件：

package com.example.handheld;
    
    import android.util.Log;
    
    import com.alibaba.fastjson.JSONObject;
    import com.cmcid.lib.Common;
    import com.cmcid.lib.Device;
    import com.cmcid.lib.OnHandleListener;
    import com.cmcid.lib.Power;
    import com.taobao.weex.annotation.JSMethod;
    import com.taobao.weex.bridge.JSCallback;
    import com.taobao.weex.common.WXModule;
    
    public class HandheldModule extends WXModule {
    
       private Device device;
       private Beep beep;
       
       public static final String TAG = "Lu Chang li";
       private JSCallback handleCallback;  
         
       OnHandleListener onHandleListener = new OnHandleListener() {
           @Override
           public void onDown() {
               if (handleCallback == null) return;
               mWXSDKInstance.runOnUiThread(new Runnable() {
                   @Override
                   public void run() {
                       JSONObject data = new JSONObject();
                       data.put("code", "down");
                       // invokeAndKeepAlive 可以持续回调， invoke只能回调一次
                       handleCallback.invokeAndKeepAlive(data);
                   }
               });
           }
    
           @Override
           public void onUp() {
               if (handleCallback == null) return;
               mWXSDKInstance.runOnUiThread(new Runnable() {
                   @Override
                   public void run() {
                       JSONObject data = new JSONObject();
                       data.put("code", "up");
                       handleCallback.invokeAndKeepAlive(data);
                   }
               });
           }
       };
    
       /**
       * 初始化
       */
       @JSMethod
       public void initHandheld(JSCallback callback) {
           device = Device.getInstance(mWXSDKInstance.getContext());        
           device.setOnHandleListener(onHandleListener);
    
           JSONObject result = new JSONObject();
           if (device.connect()) {
               result.put("code", "success");
           } else {
               result.put("code", "failure");
           }
           callback.invoke(result);
    
           beep = new Beep(mWXSDKInstance.getContext());
       }   
    
       /**
       * 设置监听器
       */
       @JSMethod
       public void setOnHandleListener(JSCallback callback) {
           this.handleCallback = callback;
       }
    
       /*
       * 设置功率
       */
       @JSMethod
       public void setPower(JSONObject option, JSCallback callback) {
           Power power = JSONObject.parseObject(option.toJSONString(), Power.class);
           JSONObject result = new JSONObject();
           try {
               device.setPower(power);
               result.put("code", "success");
               beep.playOk();
           } catch (Exception e) {
               e.printStackTrace();
               result.put("code", "failure");
               beep.playError();
           }
           callback.invoke(result);
       }
    }

1.  注册中间件：  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L1RfUmF5_size_16_color_FFFFFF_t_70_pic_center 1]  
    在 `app/assets/dcloud_uniplugins.json`文件中添加：

"plugins": [
       {
       	"type": "module",
       	"name": "HandheldModule",
       	"class": "com.example.handheld.HandheldModule"
       }
    ]

1.  在 vue 中调用 jar 包中的方法：

1.  使用 HBuilder `生成本地打包App资源` 拷贝到 app 资源文件夹下。
