推荐答案
从支持库的26.0.0版本开始，minSdk已升至14(Android 4.0，参见此链接).如果必须支持API 9级以下的平台，则必须使用版本25.4.0，这是从7开始支持每个API级别的最后一个版本.
Starting with version 26.0.0 of the Support Libraries the minSdk has been bumped to 14 (Android 4.0, see this link). If you have to support platforms down to API-Level 9 you have to use version 25.4.0 which is last one that supported every api level from 7 onwards.
注意:确实没有理由支持这种旧设备，根据最新数字，它们仅占所有设备的0.7％. (链接)
Note: There's really no reason to support such old devices, according to the latest numbers they only account for roughly 0.7% of all devices. (link)
