【问题描述】：
我学习 android 应用程序开发并尝试设置 firestore，我按照所有步骤操作，但是当我启动应用程序时它崩溃了，我无法弄清楚问题出在哪里。
我已经交叉检查了我的 gradle，一切似乎都很好。 这是我的 gradle 模块应用程序：
apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'
android {
compileSdkVersion 28
buildToolsVersion "30.0.1"
defaultConfig {
applicationId "com.example.firestoreexample"
minSdkVersion 24
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
implementation fileTree(dir: "libs", include: ["*.jar"])
implementation 'androidx.appcompat:appcompat:1.3.0'
implementation 'androidx.constraintlayout:constraintlayout:2.0.4'
implementation 'com.google.firebase:firebase-analytics:19.0.0'
implementation 'com.google.firebase:firebase-firestore:23.0.1'
implementation 'com.google.firebase:firebase-storage:20.0.0'
implementation 'com.google.firebase:firebase-auth:21.0.1'
implementation 'com.google.firebase:firebase-database:20.0.0'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test.ext:junit:1.1.2'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'
}
我还检查了我的 gradle 项目，在这方面似乎一切都很好。 这是我的 gradle 项目：
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath "com.android.tools.build:gradle:4.0.1"
classpath 'com.google.gms:google-services:4.3.8'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
每当我启动我的应用程序时，都会出现此错误消息，我无法弄清楚问题所在。 这是错误消息：
