java - 所有 com.android.support 库和 SDK 版本都必须相同、更高还是更低？

Question

如果你看看我的 2 个库(support:appcompat-v7:24.2.1 和 support:design:25.3.1)，它是一条红线，上面写着“这个库不应该使用不同的版本(25 )而不是compileSDKVersion(24)。我应该将我的SDK更改为更高版本还是将我的支持库更改为低于SDK或高于SDK？

android {
    compileSdkVersion 24
    buildToolsVersion "27.0.3"
    lintOptions{
        abortOnError false
    }
    defaultConfig {
        applicationId "com.sangabriel.myrealapp"
        minSdkVersion 23
        targetSdkVersion 24
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        multiDexEnabled true
    }
    buildTypes {
         release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
         }
     }
}

dependencies {

    // Firebase
    compile 'com.google.firebase:firebase-core:16.0.0'

    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
         exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:24.2.1'
    testCompile 'junit:junit:4.12'

    // Design library for Coordinator Layout and Toolbars
    compile 'com.android.support:design:25.3.1'

是的，当您使用任何谷歌或核心库时，其所有版本都应该相同。

In your case you can do two things. Your compileSdkVersion is 24 So that you can use either of these two things

1. You can change all your library/dependancy version to 24.2.1 as compileSdkVersion

2. You can change all your library/dependancy version to 25.3.1 to newer version

示例

1.案例一

compile 'com.android.support:appcompat-v7:24.2.1'
compile 'com.android.support:design:24.2.1'

2.案例二

compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support:design:25.3.1'
