如何在Android Studio中更改minSdk版本? [英] How to change the minSdk version in Android Studio?

问题描述

我正在尝试在手机上运行一个基本的hello world程序，但是当我指定14时，Android Studio会继续恢复到minSDK级别20.这是我正在使用的过程:

I am trying to get a basic hello world program running on my phone, however Android Studio keeps on reverting to minSDK level 20, when I specified 14. Here is the process I am using:

-启动Android Studio 0.8.2
-选择新项目
-选择最低SDK作为API 14:Android 4.0
-选择空白活动
-新项目现已开放.我的运行4.4.2 API 19的android设备已插入.
-选择运行应用"
-选择设备"对话框打开，显示我的Android设备，但兼容性显示为否，minSdk(API 20，L预览)！= deviceSdk(API19)

-Start Android Studio 0.8.2
-Select New Project
-Select Minimum SDK as API 14: Android 4.0
-Select Blank Activity
-The new project is now open. My android device, running 4.4.2 API 19 is plugged in.
-Select "Run app"
-The "Choose Device" dialog opens, shows my android device, but shows compatibility as No, minSdk(API 20, L preview)!= deviceSdk(API19)

以下是我的build.gradle:

The following is my build.gradle:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 'android-L'
    buildToolsVersion "20.0.0"

    defaultConfig {
        applicationId "com.example.victor.myapplications"
        minSdkVersion 14
        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'])
}

将'compileSdkVersion'更改为14会导致错误无法找到目标android-14".

Changing 'compileSdkVersion' to 14 results in an error, "failed to find target android-14".

有什么想法吗?谢谢！

推荐答案

"L"开发者预览版是一种特殊的雪花，它打破了版本管理的所有常规规则.:-(

The "L" Developer Preview is a special snowflake that breaks all the normal rules for version management. :-(

除非您是经验丰富的Android开发人员，专门针对"L"进行测试，否则将 compileSdkVersion 更改为类似 19 的名称(注意:可能需要您下载SDK平台的API从SDK Manager进入19级)，然后将 targetSdkVersion 更改为 19 .

Unless you are an experienced Android developer specifically testing on "L", change compileSdkVersion to something like 19 (note: may require you to download the SDK Platform for API Level 19 from the SDK Manager) and change targetSdkVersion to 19.

将'compileSdkVersion'更改为14会导致错误无法找到目标android-14".

Changing 'compileSdkVersion' to 14 results in an error, "failed to find target android-14".

您需要在SDK Manager中下载API级别14"SDK平台".

You need to download the API Level 14 "SDK Platform" in the SDK Manager.
