NOTE

This topic describes only module-specific error codes. For details about universal error codes, see Universal Error Codes.

16000001 Ability Name Does Not Exist

Error Message

The specified ability does not exist.

Description

This error code is reported when the specified ability name does not exist.

Possible Causes

The ability to query does not exist.

Solution

Check whether the values of bundleName, moduleName, and abilityName in Want are correct.
Check whether the application corresponding to bundleName in Want is installed. You can run the following command to query the list of installed applications. If bundleName is not in the query result, the application is not installed.
```
hdc shell bm dump -a
```
For a multi-HAP application, check whether the HAP to which the ability belongs is installed. You can run the following command to query the bundle information. If the installed application does not contain the corresponding HAP and ability, the HAP to which the ability belongs is not installed.
```
hdc shell bm dump -n bundleName
