This means that you have some conflicting properties in AndroidManifest.xml files that are present in your project. If you click on the error in the console you will see a big error message and the exact reason would be somewhere there, try to read it carefully.

Usually, this happens when you have different targetSdkVersion properties in different manifests. Once again, check the long error message carefully, the detailed error should be there
