Are the conditional compilation constants __ANDROID__ and ANDROID the same or different?

Question

The conditional compilation directives #if ANDROID and #if __ANDROID__ are used as if they are different, or are they? For example, you can see their usage in .NET MAUI sample projects.

Are these constants the same, and if so which one is the official?

Answer 1

Hello,

Both forms currently work exactly the same in MAUI.

According to explain the difference between #if __ANDROID__vs #if ANDROID #501, using #if ANDROID is a better option.

In the earlier .NET MAUI releases #if ANDROID didn't work but #if __ANDROID__ did work. However, since then #if ANDROID works. They've since been equivalent. The preferred and recommended approach from the product team is to use #if ANDROID. There's no guarantee that #if __ANDROID__ support will remain forever.
