// 1) DepsMutator: from the properties like native_shared_libs, java_libs, etc., modules are added

// to the (direct) dependencies of this APEX bundle.
|
|
//
|
|
// 2) apexInfoMutator: this is a post-deps mutator, so runs after DepsMutator. Its goal is to
|
|
// collect modules that are direct and transitive dependencies of each APEX bundle. The collected
|
|
// modules are marked as being included in the APEX via BuildForApex().
|
|
//
|
|
// 3) apexMutator: this is a post-deps mutator that runs after apexInfoMutator. For each module that
|
|
// are marked by the apexInfoMutator, apex variations are created using CreateApexVariations().
