How to overcome app not installed error when building from Android Studio 3.0?
For giving build for a debug Android app from Android Studio 3.0, it’s not installing in Mobile having Marshmallow and up (in Lollipop not tested).
I have used many solutions from Stack overflow but it’s still not working.
It’s always showing App Not Installed on mobile phone.
Answer
Well the original question doesn´t have enough information, but we can have some info getting some comments:
Android studio 3.0 and compileSdkVersion 26, buildToolsVersion '26.0.2',minSdkVersion 15, targetSdkVersion 26
virtual debugging option also on.
I am facing same issue after upgrading android studio from 2.3 to 3.0
Ok the message "App Not Installed" will refer to multiple causes, and please returning to Android Studio 2.3. from 3.0 is not an option!
When we upgrade from Android Studio 2.3 to 3.0 we can find some configuration issues caused mainly by the support libraries, that will cause that our application could not be installed.
To avoid this problem we need to invalidate cache in Android Studio 3.0+ and the problem will be solved.
Please try this option.
