[android] Installation error: INSTALL_FAILED_OLDER_SDK

I tried all the responses described here but my solution was changing inside my build.gradle file minSdkVersion from 8 to 9 because some libraries in my project can´t work with API 8, that´s was the reason for the message INSTALL_FAILED_OLDER_SDK:

apply plugin: 'com.android.application'

    android {
        compileSdkVersion 22
        buildToolsVersion "22.0.1"

        defaultConfig {
            applicationId "com.tuna.hello.androidstudioapplication"
            minSdkVersion 9
            targetSdkVersion 22
            versionCode 1
            versionName "1.0"
        }
