title: Android Studio : Failure [INSTALL_FAILED_OLDER_SDK]
body: <p>Today I have downloaded Android Studio v 0.8.0 beta. I am trying to test my app on SDK 17 . Android studio error <code>Failure [INSTALL_FAILED_OLDER_SDK]</code>
  Here is my android manifest </p>
  
  <pre><code>    &lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.vahe_muradyan.notes" &gt;
      &lt;application
          android:allowBackup="true"
          android:icon="@drawable/ic_launcher"
          android:label="@string/app_name"
          android:theme="@style/AppTheme" &gt;
          &lt;activity
              android:name=".Main_Activity"
              android:label="@string/app_name" &gt;
              &lt;intent-filter&gt;
                  &lt;action android:name="android.intent.action.MAIN" /&gt;
  
                  &lt;category android:name="android.intent.category.LAUNCHER" /&gt;
              &lt;/intent-filter&gt;
          &lt;/activity&gt;
      &lt;/application&gt;
  
  &lt;/manifest&gt;

  <p>It seems that android studio uses configurations in build.gradle.Here is build.gradle</p>
  
  <pre><code>    apply plugin: 'com.android.application'
  
  android {
      compileSdkVersion 'L'
      buildToolsVersion "20.0.0"
  
      defaultConfig {
          applicationId "com.vahe_muradyan.notes"
          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'])
      compile 'com.android.support:appcompat-v7:19.+'
  }
