I want to create a banner ad for a company in my app in the footer as I do someone has some stuff that can explain me how to make a banner for app. type the image below where it is marked in red, how can I put the same in my app?
If you are referring to design tools to build banner art you can use:
• Google Web Designer (specific)
• Adobe Photoshop (not specific)
• Or any existing graphic authoring tool you want, or search for banner maker online to use one of the available online options
If the question refers to the question of frameworks and code to display and monitor the banners shown in the App, I recommend editing the question to make it more specific as Marcos Henrique spoke.
