Application Configuration Options
Corona applications may be configured through two optional Lua files, which should be saved to your project folder along with your main.lua file:
• config.lua - Handles global content scaling and alignment for multiple screens, along with a variety of other runtime options like the framerate and antialiasing for vector graphics. (See documentation here)
• build.settings - Handles build options like the screen orientation(s), the setting of Info.plist values for iOS and/or application permissions for Android. (See documentation here)
Note: the information in this section has been consolidated into the "Configuring Projects" section of the Corona API Reference. For a detailed reference for the above options, please see that section.
