如何解决build.gradle中不同版本库的错误？

Question

我正在Android开发，并尝试实现GPS和谷歌地图。

build.gradle(Module:app) 如下所示

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.2"
    defaultConfig {
        multiDexEnabled true
        applicationId "com.app.t.pro"
        minSdkVersion 21
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

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

    compile 'com.android.support:appcompat-v7:26.+'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    compile 'com.android.support:design:26.+'
    compile 'com.google.android.gms:play-services:11.0.4'
    compile 'com.google.android.gms:play-services-maps:11.0.4'
    testCompile 'junit:junit:4.12'
}

但它在compile 'com.android.support:appcompat-v7:26.+' 处显示错误。 错误是

All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 26.1.0, 25.2.0. Examples include com.android.support:animated-vector-drawable:26.1.0 and com.android.support:mediarouter-v7:25.2.0 less... (Ctrl+F1) 
There are some combinations of libraries, or tools and libraries, that are incompatible, or can lead to bugs. One such incompatibility is compiling with a version of the Android support libraries that is not the latest version (or in particular, a version lower than your targetSdkVersion.)

但我在build.gradle 中没有看到任何version-25。 我错过了什么吗？ 提前致谢。

Answer 1

tl;dr 您需要将 Google Play 库更新到至少 11.2+

查看Google Play Release Notes

11.2 中的 SDK 版本支持

当您将应用的 Play 服务依赖项升级到 11.2.0 或更高版本时，还必须更新应用的 build.gradle 以指定 compileSdkVersion 至少为 26 (Android O)。这不会改变您的应用程序的运行方式。您将不需要更新 targetSdkVersion。如果您将 compileSdkVersion 更新为 26，您可能会在构建中收到错误消息，并显示以下有关 Android 支持库的消息：

This support library should should not use a different version (25) than the compileSdkVersion (26).

可以通过将您的支持库依赖项升级到至少版本 26.0.0 来解决此错误。

Answer 2

设置

compile 'com.android.support:appcompat-v7:26.1.0'
compile 'com.android.support:design:26.1.0'

和

compile 'com.google.android.gms:play-services-maps:11.4.2'
compile 'com.google.android.gms:play-services-location:11.4.2'

同时删除，

compile 'com.google.android.gms:play-services:11.4.2'
