It's a issue with instant-Run and for warning Before Android 4.1 as doc says:

Instant Run is supported only when you deploy the debug build variant, use Android Plugin for Gradle version 2.0.0 or higher, and set minSdkVersion to 15 or higher in your app's module-level build.gradle file. For the best performance, set minSdkVersion to 21 or higher.

you can see full documentation here.

Recommended to disable Instant-run or set min-sdk to 15 or higher.
