已解决，谢谢你了。
问题原因是把
```java
Operation operation = Intent.OperationBuilder()
.withDeviceId("")
.withBundleName("com.example.myapplication")
.withAbilityName("com.example.myapplication.SecondAbility")
.build();
写成
Operation operation = new Intent.OperationBuilder()
.withDeviceId("")
.withBundleName("com.example.myapplication")
.withAbilityName("com.example.myapplication. SecondAbility")
.build();
在 SecondAbility前多了一个空格，编译时没发现。
在HarmonyOS鸿蒙Next中，如果示例程序无法实现页面跳转，可能的原因包括以下几个方面：
-
页面路由配置错误：检查
config.json或module.json文件中的路由配置是否正确，确保目标页面已正确注册。 -
页面路径错误：在调用
router.push或router.replace方法时，确认传入的路径与配置文件中定义的路径一致。 -
页面生命周期问题：确保目标页面的生命周期方法（如
onPageShow、onPageHide）没有阻止页面跳转的逻辑。 -
权限问题：某些页面跳转可能需要特定的权限，检查是否已正确申请并授予相关权限。
-
资源加载问题：如果目标页面依赖的资源未正确加载，可能导致跳转失败，检查资源文件是否存在且路径正确。
-
代码逻辑错误：检查跳转逻辑代码，确保没有语法错误或逻辑错误导致跳转失败。
-
系统版本兼容性：确认示例程序与当前鸿蒙Next系统版本兼容，某些API或功能可能在特定版本中不可用。
-
调试信息：通过日志或调试工具查看跳转过程中的错误信息，定位具体问题。
以上是可能导致页面跳转失败的常见原因，需逐一排查。
