这是我第一次使用Firebase，我已经完成了Firebase for android提供的视频和文档中的每一步，但是当我运行我的项目时，我遇到了这个错误。

To run dex in process, the Gradle daemon needs a larger heap.
It currently has approximately 910 MB.
For faster builds, increase the maximum heap size for the Gradle daemon to more than 2048 MB.
To do this set org.gradle.jvmargs=-Xmx2048M in the project gradle.properties.
For more information see https://docs.gradle.org/current/userguide/build_environment.html

我添加了所需的路径和依赖项：
这是我的build.gradle（项目：试试）
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.1.2'
classpath 'com.google.gms:google-services:3.2.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
maven {
url 'https://maven.google.com'
}
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
这是我的build.gradle（模块：app）
apply plugin: 'com.android.application'
android {
compileSdkVersion 24
buildToolsVersion "25.0.3"
defaultConfig {
applicationId "com.salmasamy.trytrytry"
minSdkVersion 19
targetSdkVersion 24
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:24.2.1'
compile 'com.google.firebase:firebase-core:11.8.0'
compile 'com.google.firebase:firebase-firestore:11.8.0'
}
apply plugin: 'com.google.gms.google-services'
我还在project-> app文件夹中添加了google-services.json文件，并确保没有额外的空格，并且我有正确版本的google play服务和google存储库。
当我构建项目时，一切都很好，但是只有在我运行它时才能得到它。
因为你应该使用gradle 3. +
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.1'
classpath 'com.google.gms:google-services:3.1.1'
}
}
allprojects {
repositories {
maven { url 'https://maven.google.com' }
jcenter()
}
}
