Question

创建新项目时，出现此错误：

Android resource compilation failed

我的gradle工具版本：

classpath 'com.android.tools.build:gradle:3.2.0-alpha11'

我的礼物：

distributionUrl=https\://services.gradle.org/distributions/gradle-4.6-all.zip

我的build.gradle：

apply plugin: 'com.android.application'

android {



  compileSdkVersion 27
    defaultConfig {
        minSdkVersion 16
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

我尝试删除build .gralde .idea，但不起作用

我的Android Studio版本是3.1.4

我运行旧项目没有问题，只是创建新项目。

这是我在Stack Overflow中的第一个问题，格式可能不正确 谢谢您的帮助。
