############################################################################### # ERROR: Backward incompatible change detected on AIDL API # ############################################################################### Above AIDL file(s) has changed in a backward-incompatible way, e.g. removing a method from an interface or a field from a parcelable. If a device is shipped with this change by ignoring this message, it has a high risk of breaking later when a module using the interface is updated, e.g., Maineline modules.
