@cctvbnm1111 Can you please include the version of build-tools you are using? You can find this information in a Diagnostic Build Output.

I believe you need to use a minimum of build-tools v25+ for proper support of this version of support library. With that said, it's easiest to just use the latest version of build-tools as they are typically additive.

As a rule of thumb, you should be using a version of build-tools that is equal or greater than both the support library and <TargetFrameworkVersion>. In your case that would be v25+ across the board. Since Android is additive by nature, installing the latest usually gets you the best compatibility.

@JonDouglas
yes， it's v25+

@cctvbnm1111 I was not able to reproduce this with the steps you've provided. Can you please upload a minimal, complete, and verifiable example?

I tested this both against v26 and v25 support library versions and was able to deploy & run an app against > API 19 and <= API 19.

Please also include what API level of android you are deploying to(Device/Emulator).
