Failure [INSTALL_FAILED_OLDER_SDK] Android Studio

Question

I\'m new to Android and I\'m using the Android Studio. I\'ve created a new project just to show the Hello World! but I can\'t get it working on the AVD because of this error

Answer 1

I think projects with

 compileSdkVersion 'android-L'

cannot be installed in other Android versions right now. I might be wrong there but if you're not doing anything specific to the L preview SDK, just set the compile version to one of the official ones. Same goes for the targetSdk.

You can choose those in the Create Project wizard.
