HarmonyOS 鸿蒙Next 跨设备访问DataAbility的坑点

HarmonyOS 鸿蒙Next 跨设备访问DataAbility的坑点 注意！！！访问远程设备的Data Ability除了上面讲的uri里添加DevcieId以外，必须注意下面几点：

1. 要定义应用级别的访问Data Abiltiy的权限

{
    "name": "cn.ybzy.hmsdemo.DataAbilityShellProvider.PROVIDER",
    "grantMode": "system_grant"
}

1. 要加分布式数据同步和设备信息获取权限

{
    "name": "ohos.permission.GET_DISTRIBUTED_DEVICE_INFO"
},
{
    "name": "ohos.permission.DISTRIBUTED_DATASYNC"
},
{
    "name": "ohos.permission.READ_USER_STORAGE"
},
{
    "name": "cn.ybzy.hmsdemo.DataAbilityShellProvider.PROVIDER"
}

requestPermissionsFromUser(new String[]{"ohos.permission.DISTRIBUTED_DATASYNC", "ohos.permission.servicebus.ACCESS_SERVICE", "com.huawei.hwddmp.servicebus.BIND_SERVICE"}, 0);

1. Data Ability的注册信息中一定要打开允许其他应用访问的权限

{
    "visible": true, //最后的坑，创建Data Ability时候不会自动添加
    "permissions": [
        "cn.ybzy.hmsdemo.DataAbilityShellProvider.PROVIDER"
    ],
    "name": "cn.ybzy.hmsdemo.SimpleDataAbility",
    "icon": "$media:icon",
    "description": "hap sample empty provider",
    "type": "data",
    "uri": "dataability://cn.ybzy.hmsdemo.SimpleDataAbility"
}
