Hi @usmanafzal,

Thanks for asking this here! 🙂

You can run / specify the flavor specific Gradle Task, every flavor should have e.g. an `assembleX` task which can be run as a gradle task:

You can set the Gradle task as the **Gradle task to run** option of the **Gradle Runner** step.

**You can get the full list of tasks you can run with gradle on your project with** : `gradle tasks`

Just create corresponding workflows, or use Workflow Environment Variables for beta, staging, production, … and specify the Triggers when to run which workflow: [Using the Trigger Map to trigger builds - Bitrise Docs](http://devcenter.bitrise.io/webhooks/trigger-map/)

A very minimal (not complete, only for demonstration!) example:

```auto
format_version: 1.3.1
default_step_lib_source: https://github.com/bitrise-io/bitrise-steplib.git
trigger_map:
- push_branch: master
  workflow: release
- push_branch: '*'
  workflow: beta
- pull_request_source_branch: '*'
  workflow: beta
workflows:
  beta:
    steps:
    - gradle-runner@1.5.4:
        inputs:
        - gradle_task: assembleOne
  release:
    steps:
    - gradle-runner@1.5.4:
        inputs:
        - gradle_task: assembleTwo

```

This configuration will select the `release` workflow for pushes on the `master` branch, and for pushes on any other branch and for Pull Requests it’ll select the `beta` workflow.

The beta workflow’s gradle runner step will run the `assembleOne` gradle task, while the `release` workflow’s gradle runner will run the `assembleTwo` task.

If you have any questions just let us know!  
Happy Building! 😉
