在添加 firebase 项目所需的行后尝试同步我的 android studio 项目时出现此错误。就是这样,这是一个常见的 android studio 项目,我只想在其中应用一个 firebase 数据库。请问,如果有人知道会发生什么?谢谢。
PD:我已经在其他 stackoverflow 问题上搜索过这个错误,但没有一个答案对我有用:(
这是我的 build.gradle(项目):
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.4.1'
classpath 'com.google.gms:google-services:4.3.4'
//classpath 'com.google.firebase:firebase-crashlytics-gradle:2.2.1'
// 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
}
还有我的 buid.gradle(app):
apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'
android {
compileSdkVersion 28
buildToolsVersion "29.0.0"
defaultConfig {
applicationId "com.example.proceedingmanager"
minSdkVersion 21
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support.constraint:constraint-layout:2.0.4'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
