I have problem building game for older versions of android. I setup SDK min support for 21 and installed SDK on Codeworks (1R6u1). When i build APK for shipping it uses android-21 NDK but after APK is built only on 8.0 android it can be installed. On older versions of android I get “App not installed - phone does not support this version” (Android 7 and 6). Any suggestions in which direction to look or what to test? I use UE 4.19 for this build.
