AAPT2: Implement attribute compat versioning This change defines some hardcoded rules to degrade attributes in newer SDKs to specific older attributes. An attribute with a degrade rule will generate a new XML for the API in which the attribute resulting from the degradation was introduced. Since API 22 (Lollipop MR1), attributes are correctly ignored and do not need to be versioned. In XML files defined for APIs 22+, the original and degraded attributes coexist in the same XML file. One such example is paddingHorizontal, introduced in API 26. paddingHorizontal degrades to paddingLeft and paddingRight, which were both introduced in API 1.
