Gradle同步失败:原因:未指定compileSdkVersion [英] Gradle sync failed: Cause: compileSdkVersion is not specified

问题描述

我正在尝试在android studio中测试我的离子应用程序.它抛出以下错误.

I am trying to test my ionic app in android studio. It is throwing the below error.

Gradle sync failed: Cause: compileSdkVersion is not specified.

对此有什么解决方案?我在做什么错了.

Any solution for this ? What am I doing wrong.

这是我的build.gradle文件

Here is my build.gradle file

apply plugin: 'com.android.application'

buildscript {
    repositories {
        mavenCentral()
        jcenter()
        maven {
            url "https://maven.google.com"
        }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0'
    }
}

// Allow plugins to declare Maven dependencies via build-extras.gradle.

allprojects {
    repositories {
        mavenCentral();
        jcenter()
    }
}

task wrapper(type: Wrapper) {
    gradleVersion = '4.1.0'
}

dependencies {
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:+'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:+'
    implementation 'com.android.support:appcompat-v7:27.+'
}

推荐答案

您正在使用27.+的 android支持库，因此您必须提供sdk版本27作为和targetSdkVersion，否则您的项目不知道应针对哪个平台构建项目.这些参数应在 build.gradle(app)中的android目录中指定:

You are using android support library of 27.+ so you will have to give sdk version 27 as compileSdkVersion and targetSdkVersion otherwise your project does not know for which platform your project should be built. These parameter should be given in android directory like this in build.gradle(app):

android {
    compileSdkVersion 27
    buildToolsVersion '27.0.3'
    defaultConfig {
        applicationId "com.example.abc.test"
        minSdkVersion 21
        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'
        }
    }
}

只需将此代码粘贴在apply plugin: 'com.android.application'此行下方

Just paste this code below apply plugin: 'com.android.application' this line
