## Information

Error stacktrace:

```
Unable to graft xml at selector "/manifest/uses-sdk" from "C:\Users\norman\development\gradletest\platforms\android\app\src\main\AndroidManifest.xml" during config install

### Command or Code

Use `cordova create` to build a simple hello world project.

Inside the `config.xml` add:

```xml

```

This is a copied and paste example from the [docs](https://cordova.apache.org/docs/en/latest/plugin_ref/spec.html#edit-config). But this appears to occur when having `target="/manifest/uses-sdk"`, regardless of the body of `` block. This also fails if `mode="merge"` is set.

Do note that the following does **not** fail:

```xml

```

This leads me to believe perhaps this occurs if the `AndroidManifest.xml` does not have the target node.

Finally run: `cordova build android` to observe the failure.

### Environment, Platform, Device

Windows 10
Cordova-Android 9

### Version information

Windows 10
cordova: 9.0.0 (cordova-lib@9.0.1)

## Checklist

- [x] I searched for existing GitHub issues
- [x] I updated all Cordova tooling to most recent version
- [x] I included all the necessary information above

Reproduce the failure with the documented edit-config example and cordova build android, then inspect ConfigChanges/ConfigFile.js at the graft_child path shown in the stack trace. Compare the /manifest/uses-sdk case with the working /manifest target case and check related config-change handling. Done means the example applies successfully without the graft error and the Android build completes.
