Android.bp accessibility

[REGURI AKANKSHA]

Is there any case that  Android.bp can access variables declared in other files.

say a variable "platform" is declared in some .mk file Can Android.bp now use that variable "platform"

As per my knowledge it's "no" but I want to make sure about this

Thanks in advance

Soong cannot access variables defined in Make.

For variables defined in Android.bp files this is documented at https://android.googlesource.com/platform/build/soong/+/master/README.md#variables:

"Variables are scoped to the remainder of the file they are declared in, as well as any child blueprint files."

Can u help me know how to define a variable of type string in Android.bp?

say if in a folder1/Android.bp string x = "hello" is defined. As per above explaination this variable x can accessed in folder1/folder2/Android.bp ryt?

say a module_name is equated to x, then the module name becomes hello? In what fashion  folder1/folder2/Android.bp can  access x?

Thanks in advance.
