After changing android api version from 23 to 19, cordova gives deprecated API error. How to decide?

Question

Java

Everything works with the android-23 version, but I need to make support for android 4+ and try to build it in another API
ionic platform add android
, it immediately makes version 23.
I can’t find it - How can I add the old version right away?
And then I reduce to the old one

android update project --subprojects --path "platforms/android" --target android-19 --library "CordovaLib"

From the command, he replaced it like everywhere except the AndroidManifest.xml file

<uses-sdk android:minSdkVersion="14" android:targetSdkVersion="23" />

here, too, I changed it with my hands to 19.
After I do build and gives errors:
