安卓工作室 : Failure [INSTALL_FAILED_OLDER_SDK]

Question

今天我下载了 Android Studio v 0.8.0 beta。我正在尝试在 SDK 17 上测试我的应用程序。 Android Studio 错误 Failure [INSTALL_FAILED_OLDER_SDK]这是我的安卓 list

    <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.vahe_muradyan.notes" >
    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".Main_Activity"
            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>

好像android studio使用build.gradle中的配置。这里是build.gradle

    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.+'
}

有我的配置支持L和旧版本的android:

apply plugin: 'com.android.application'

android {
    buildToolsVersion "20.0.0"

    defaultConfig {
        applicationId "com.example.uladzimir_klyshevich.myapplication"
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }


    productFlavors {
        l {
            minSdkVersion 'android-L'
            targetSdkVersion 'android-L'
            compileSdkVersion 'android-L'
        }
        old {
            minSdkVersion 10
            targetSdkVersion 20
            //TODO comment second line if build is not compiles for "L"
            compileSdkVersion 20
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    lCompile 'com.android.support:appcompat-v7:21.+'
    oldCompile 'com.android.support:appcompat-v7:19.1.0'
}

结果你会有味道:

oldDebug
oldRelease
lDebug
lRelease

并且可以在旧版本的android上安装你的应用程序。
