Question

I'm new to Android and Android Studio. I created a HelloWorld project in Android Studio. When I'm running the app on my device I get following warnings.. How can I fix these warnings?

If you aren't running the app on an ARM chipset device, I'd say you can ignore the first 2 – Varicella

Answer 1

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.

What about the ClassLoader referenced unknown path warning. How can I fix this? – Maritime

@Maritime As I remember both issue gone when I set min sdk 15. – Chasteen

minSdkVersion is already set to 15, so this solution do not work – Maritime

Answer 2

Try uninstalling the app ,So it forces the closure of the Instant Run. it worked for me .
