是否必须使用api 22棒棒糖编译我的应用程序？ [英] Is it mandatory to compile my app with api 22 lollipop?

问题描述

我的项目使用api 21编译并运行正常，当我尝试使用api 22编译时，我遇到了gradle的许多错误（错误：在< declare-styleable> SherlockSpinner中，找不到android：popupPromptView属性，以及许多其他错误），我无法修复它们。

My project compiles and runs fine with api 21 and when i try to compile it with api 22 i'm facing many errors from gradle (Error:In <declare-styleable> SherlockSpinner, unable to find attribute android:popupPromptView, and many other errors) and i can't fix them.

所以问题是，如果我放开api 22并仅用api 21进行编译，会发生什么情况？哪些设备无法运行我的应用程序？

So the question is what happens if i let api 22 go and just compile it with api 21, and which devices can't run my app?

更新：

请查看我的配置并告诉我设备无法运行我的应用程序
这是我的build.gradle配置文件的一部分：

Please take a look at my config and tell me which devices can't run my app this is a part of my build.gradle config file:

apply plugin: 'com.android.application'
android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        minSdkVersion 9

    }

    packagingOptions {
        exclude 'META-INF/LICENSE.txt'
    }

    lintOptions {
        abortOnError false
        checkReleaseBuilds false
    }
}
dependencies {
    compile 'com.android.support:support-v4:21.0.3'

推荐答案

编译仅当您要使用特定SDK版本提供的功能时，才需要通过定义特定的SDK版本来定义您的应用程序。

Compiling your application by defining particular compile SDK version is only required if you would want to use the features provided by that particular SDK version.

您绝对可以使用较低版本进行编译，使其与较高版本兼容，但是如上所述，您将无法使用由定义的新功能/功能更高的版本。

You can definitely compile with lower version and make it compatible for the higher version, but as said above you won't be able to use the new functionalities/features defined by higher version.
