问题描述

我是新的Andr​​oid和我使用​​的是Android的工作室。我创建了一个新的项目只是为了显示世界您好！但我不能让它工作，因为这个错误的AVD：失败[INSTALL_FAILED_OLDER_SDK]

I'm new to Android and I'm using the Android Studio. I've created a new project just to show the Hello World! but I can't get it working on the AVD because of this error: Failure [INSTALL_FAILED_OLDER_SDK].

我已经搜索的答案，我知道这是一些关于build.gradle和的minSdkVersion但是任何答案为我工作。

I already searched for the answer and I know it's something about the build.gradle and the minSdkVersion but any of the answers worked for me.

这是我的Andr​​oidManifest.xml：

This is my 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>

这是我build.gradle：

And this is my 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'])
}

我会AP preciate不仅是答案，但解释。

I would appreciate not only the answer but the explanation.

感谢您！

推荐答案

除非你知道你想被使用Android大号开发preVIEW您的应用程序，不针对与它进行编译。它在很大程度上仍然是一个preVIEW释放，看来好像应用目标和编译为preVIEW导致这个错误与任何非-L设备。

Unless you know you want to be using the Android L developer preview with your application, do not target and compile with it. It is still very much a preview release, and it appears as though applications targeting and compiling for the preview cause this error with any non-L device.

在你的build.gradle更新这些行坚持使用最新的稳定版本（Android 4.4系统，API 19）：

Update these lines in your build.gradle to stick with the latest stable release (Android 4.4, API 19):

android {
    compileSdkVersion 19

    defaultConfig {
        targetSdkVersion 19
    }
}
