Answer: 
At the top of your *module's* `build.gradle` file there's a specification which build tools the module uses. Fix it to latest.

```
buildToolsVersion "24.0.2"

```
Go to build.gradle(Module:app) and update the `buildToolsVersion '24.0.0 rc2'` to `buildToolsVersion '24.0.0'` or to the latest version
