使用gradle buildTypes的android不同APK

我试图在同一台设备上安装调试版本和发布版本,以便在gradle文件的buildTypes块中添加applicationIdSuffix,如文档中所述。没有提到创建任何包,而是说包未找到错误。请帮忙。

apply plugin: 'com.android.application'
apply plugin: 'io.fabric'

def versionMajor = 1
def versionMinor = 0
def versionPatch = 4
def versionBuild = 0

android {
    compileSdkVersion 26
    defaultConfig {
        applicationId "com.edu.gcfapp"
        minSdkVersion 21
        targetSdkVersion 26
        versionCode versionMajor * 10000 + versionMinor * 1000 + versionPatch * 100 + versionBuild
        versionName "${versionMajor}.${versionMinor}.${versionPatch}"
        multiDexEnabled true
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        javaCompileOptions {
            annotationProcessorOptions {
                arguments = ["room.schemaLocation": "$projectDir/schemas".toString()]
            }
        }
    }
    buildTypes {

        debug {
            applicationIdSuffix ".debug"
        }

        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
    flavorDimensions "default"

我得到的错误是。。
