IDL Service connectRemoteAbility failed, errorCode is 1203

报错日志如下：

通过如下方式建立IDL连接失败：

Intent intent = new Intent();Operation operation = new Intent.OperationBuilder() .withDeviceId("deviceId") .withBundleName("com.example.test") .withAbilityName("com.example.test.TestService") .build();intent.setOperation(operation);connectAbility(intent, new IAbilityConnection() {     ……}

"com.example.test.TestService"的config.json配置如下：

"abilities": [  {"backgroundModes": [   "dataTransfer",   "location" ], "name": "com.example.test.TestService", "icon": "$media:icon", "description": "$string:testservice_description", "type": "service", "process": ".TestService", "visible": true}]

"com.example.test.TestService"的启动在MainAbility.java的onStart()中：

Intent newIntent = new Intent();Operation operation = new Intent.OperationBuilder()    .withDeviceId("deviceId")    .withBundleName("com.example.test")    .withAbilityName("com.example.test.TestService")    .build();newIntent.setOperation(operation);startAbility(newIntent);

原因是没有理解启动本地服务和启动远程服务的区别

启动本地设备Service的代码示例如下：

Intent intent = new Intent();Operation operation = new Intent.OperationBuilder() .withDeviceId("") .withBundleName("com.huawei.hiworld.himusic") .withAbilityName("com.huawei.hiworld.himusic.entry.ServiceAbility") .build();intent.setOperation(operation);startAbility(intent);

因为我是做本地服务的IDL通信，所以要选择空的.withDeviceId(“”)。

启动远程设备Service的代码示例如下：

Operation operation = new Intent.OperationBuilder() .withDeviceId("deviceId") .withBundleName("com.huawei.hiworld.himusic") .withAbilityName("com.huawei.hiworld.himusic.entry.ServiceAbility") .withFlags(Intent.FLAG_ABILITYSLICE_MULTI_DEVICE) // 设置支持分布式调度系统多设备启动的标识 .build();Intent intent = new Intent();intent.setOperation(operation);startAbility(intent);

当调用connectAbility()接口时，定义operation使用.withDeviceId()要与startAbility()时保持一致。
