车载通信技术原理-CAN通讯和代码配置：奥迪A6轿车总线拓扑图 CAN总线是一种用于汽车监测与控制系统的串行通信协议，由德国Bosch公司开发。它具有多主工作方式、优先级仲裁、高抗干扰等特点，支持点对点、广播等多种通信方式，传输距离可达10公里。CAN协议采用差分信号传输，物理层使用双绞线，数据链路层实现错误检测、位填充等功能。协议帧类型包括数据帧、遥控帧、错误帧等。CAN总线自1986年发布以来，已成为汽车电子系统的标准配置，广泛应用于车载网络。文章还提供了S32K144芯片的CAN驱动代码示例。阅读详情

         i.setComponent(cn);
         i.setAction("android.intent.action.MAIN");
         startActivityForResult(i, RESULT_OK);

20.调用系统编辑添加联系人（高版本SDK有效）：

            // it.setType(Contacts.CONTENT_ITEM_TYPE);
            it.putExtra("name", "myName");
            it.putExtra(android.provider.Contacts.Intents.Insert.COMPANY,  "organization");
            it.putExtra(android.provider.Contacts.Intents.Insert.EMAIL, "email");

                              "workPhone");

            startActivity(it);

21.调用系统编辑添加联系人（全有效）：
Intent intent = new Intent(Intent.ACTION_INSERT_OR_EDIT);
         intent.setType(People.CONTENT_ITEM_TYPE);
         intent.putExtra(Contacts.Intents.Insert.NAME, "My Name");
         intent.putExtra(Contacts.Intents.Insert.PHONE, "+1234567890");
         intent.putExtra(Contacts.Intents.Insert.PHONE_TYPE, Contacts.PhonesColumns.TYPE_MOBILE);
         intent.putExtra(Contacts.Intents.Insert.EMAIL, "com@com.com");
         intent.putExtra(Contacts.Intents.Insert.EMAIL_TYPE,                   Contacts.ContactMethodsColumns.TYPE_WORK);
         startActivity(intent);

22(更新)
  //直接打电话出去
Uri uri = Uri.parse("tel:0800000123");
Intent it = new Intent(Intent.ACTION_CALL, uri);
startActivity(it);
//用這個，要在 AndroidManifest.xml 中，加上
//<uses-permission id="android.permission.CALL_PHONE" />

23.最基本的share 信息的intent，可以传一段text信息到各个手机上已安装程序：如SMS，Email，sina微波，米聊，facebook，twitter等等

            Intent it = new Intent(Intent.ACTION_SEND);
            it.putExtra(Intent.EXTRA_TEXT, "The email subject text");
            it.setType("text/plain");
            startActivity(Intent.createChooser(it, "Choose Email Client"));

24.调用skype 的intent

方法1：老版，新版不可用，可能是因为skype的activity结构变动：

//       Intent sky = new Intent("android.intent.action.CALL_PRIVILEGED");
//       sky.setClassName("com.skype.raider",
//             "com.skype.raider.contactsync.ContactSkypeOutCallStartActivity");
//       sky.setData(Uri.parse("tel:" + phone));
//       startActivity(sky);

方法2：打开到skype的main page：

//       PackageManager packageManager = getActivity().getPackageManager();
//       Intent skype = packageManager.getLaunchIntentForPackage("com.skype.raider");
//       skype.setData(Uri.parse("tel:65465446"));
//       startActivity(skype);

方法3：传入号码，直接进入skype拨号画面并打电话：

      Intent intent = new Intent("android.intent.action.CALL_PRIVILEGED");
      intent.setClassName("com.skype.raider",
      "com.skype.raider.Main");
      intent.setData(Uri.parse("tel:" + phone));
      startActivity(intent);
