What does “Failure [INSTALL_FAILED_OLDER_SDK]” mean in Android Studio?

Question

I got this Froyo (2.2) device that I am using to make an app. When I try to run the app directly to the device it shows an error saying

pkg:

Fix your gradle file the following way

defaultConfig {
    applicationId "package.com.app"
    minSdkVersion 8 //this should be lower than your device
    targetSdkVersion 21
    versionCode 1
    versionName "1.0"
}
