Final answer:
In Android programming, it is considered a best practice to use the metric system for expressing measurements.
Step-by-step explanation:
In the context of Android programming, while Android does support other units of measurement, it is generally considered a best practice to use the metric system for expressing measurements.
The metric system, also known as the International System of Units (SI), is a decimal-based system that is widely used in scientific and technical fields.
Using the metric system provides consistency and makes it easier to convert between different units within the system.For font sizes, the recommended unit is scale-independent pixels (sp), which scales with the user's preferred text size.
