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"
}
