Android Virtual Flic Button Application Creation

I require the development of a virtual flic button app for my Android device. This application should be configured to trigger a specific event within my existing app that is already paired with a physical flic button. The ideal developer should possess the following skills and experience:

- Strong proficiency in Android development
- Experience in developing apps that can interact with other applications

App Requirements:

• Capable of being clicked once, twice, or held down to start an action in the existing app on the same device.

• Should have an interface.

Please note that my existing application is already developed and running smooth on the device. Let's chat if you have experience with similar projects.
