xml - Failure [INSTALL_FAILED_OLDER_SDK] Android Studio -

i'm new android , i'm using android studio. i've created new project show hello world! can't working on avd because of error: failure [install_failed_older_sdk].

i searched answer , know it's build.gradle , minsdkversion of answers worked me.

this androidmanifest.xml :

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android"     package="com.example.scoelli.test" >      <application         android:allowbackup="true"         android:icon="@drawable/ic_launcher"         android:label="@string/app_name"         android:theme="@style/apptheme" >         <activity             android:name=".myactivity"             android:label="@string/app_name" >             <intent-filter>                 <action android:name="android.intent.action.main" />                  <category android:name="android.intent.category.launcher" />             </intent-filter>         </activity>     </application>  </manifest> 

and build.gradle :

apply plugin: 'com.android.application'  android {     compilesdkversion 'android-l'     buildtoolsversion "20.0.0"      defaultconfig {         applicationid "com.example.scoelli.test"         minsdkversion 8         targetsdkversion 'l'         versioncode 1         versionname "1.0"     }     buildtypes {         release {             runproguard false             proguardfiles getdefaultproguardfile('proguard-android.txt'), 'proguard-rules.pro'         }     } }  dependencies {     compile filetree(dir: 'libs', include: ['*.jar']) } 

i appreciate not answer explanation.

thank you!

unless know want using android l developer preview application, not target , compile it. still preview release, , appears though applications targeting , compiling preview cause error non-l device.

update these lines in build.gradle stick latest stable release (android 4.4, api 19):

android {     compilesdkversion 19      defaultconfig {         targetsdkversion 19     } }
