usePlugins

If usePlugins is enabled, the doPlugins() function runs just before AppMeasurement compiles and sends a hit to Adobe. Enable this variable if you use the doPlugins() function.

Use Plug-ins in Adobe Experience Platform Launch

There is not a dedicated field in Launch to use this variable. Use the custom code editor, following AppMeasurement syntax.

s.usePlugins in AppMeasurement and Launch custom code editor

The s.usePlugins variable is a boolean that determines if AppMeasurement calls the doPlugins() function. Its default value is false. Set this variable to true if you use the doPlugins() function in your implementation.

s.usePlugins = true;
