**Example**

```ts
import { appManager } from '@kit.AbilityKit';
import { hilog } from '@kit.PerformanceAnalysisKit';
import { BusinessError } from '@kit.BasicServicesKit';

try {
  let bundleName = "ohos.samples.etsclock";
  appManager.getRunningMultiAppInfo(bundleName).then((info: RunningMultiAppInfo) => {
      hilog.info(0x0000, 'testTag', `getRunningMultiAppInfo success`);
    }).catch((err: BusinessError) => {
      hilog.error(0x0000, 'testTag', `getRunningMultiAppInfo error, code: ${err.code}, msg:${err.message}`);
    })
} catch (err) {
  hilog.error(0x0000, 'testTag', `getRunningMultiAppInfo error, code: ${err.code}, msg:${err.message}`);
}
```
