此行显示

时出错

所有com.android.support库必须使用完全相同的版本规范（混合版本可能导致运行时崩溃）。找到版本27.1.1、26.1.0。示例包括com.android.support:animated-vector-drawable:27.1.1和com.android.support:customtabs:26.1.0

implementation 'com.android.support:appcompat-v7:26.1.0'

是我的

app.gradle

apply plugin: 'com.android.application'


android {
    compileSdkVersion 26
    defaultConfig {
        applicationId "com.example.akhilkumar.chitchat"
        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'
        }
    }

Answer 1

出现此错误是因为您可以使用旧版本，因此只需更新版本依赖项即可。

更改：

compileSdkVersion 26或targetSdkVersion 26

要

compileSdkVersion 27或targetSdkVersion 27

也要更改：

implementation 'com.android.support:appcompat-v7:27.1.1'

implementation 'com.android.support:customtabs:27.1.1'

implementation 'com.android.support:design:27.1.1'

Sync.. 和 Clean & ReBuild

Answer 2

我通过简单地更改

来解决此问题

实现'com.android.support:design:26.1.0'

收件人

implementation 'com.android.support:design:27.1.0'
implementation 'com.android.support:appcompat-v7:26.1.0'
implementation 'com.android.support:support-v4:26.1.0'

我希望这会有所帮助...也进行gradle更新专门用于响应本机导航v2
