What does this mean and how do I get around it?:
adb: failed to install MacroDroidHelper.apk: Failure [INSTALL_FAILED_DEPRECATED_SDK_VERSION: App package must target at least SDK version 23, but found 21]
This is just weird. Before doing anything to my S8+, I deleted the helper app from my Ultra. I'm still farting around with getting helper reinstalled - no joy so far. Then I went back to see how the permissions were set on the S8+. I can't remember how they were, but I reset them, and it works!
Thinking simplistically, doesn't it seem like I should be able to copy helper from one to m the other?
