   * Sometimes internal methods return different types for different SDKs. It's safe because
   * these methods are internal/private methods, not public methods. To support different return
   * types of a method for different SDKs, we often use looseSignature method, although all return
   * types are common types like bool and int. This field/property can be used to fix this issue by
   * using different real methods for different SDKs.
   *
   * @return The expected implemented method name. If it is empty/null, the Robolectric will uses
   *     the method's name that marked by @Implementation as the implemented method name.
