我对Android工作室很陌生,在搜索这个网站以寻找问题时,我似乎遇到了一个全新的问题。
我尝试同步我的Grandle文件时遇到的主要问题通常是“请将版本更新为(版本号)”
我是这样做的,但到那时我会得到一个或多个错误,上面写着“无法解决:[app name and version]”
此时我该怎么办?现在似乎没有任何意义,考虑到基于此我发现的其他一切都应该修复它。
我的代码如下
apply plugin: 'com.android.application'
android {
compileSdkVersion 27
defaultConfig {
applicationId "twitchy.groupchatapp"
minSdkVersion 25
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'
}
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:27.1.0'
implementation 'com.android.support.constraint:constraint-layout:1.0.2'
implementation 'com.android.support:design:23.4.0'
implementation 'com.google.firebase:firebase-core:11.8.0'
implementation 'com.firebaseui:firebase-ui:0.6.0'
implementation 'com.google.firebase:firebase-auth:9.2.1'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.1'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
}
apply plugin: 'com.google.gms.google-services'
非常感谢您的任何帮助 *注意:代码在我更改之前具有相同的版本号 以下是我在
时收到的错误Failed to resolve: com.android.support.constraint:constraint-layout:11.4.2

现在添加了Build level Gradle
// 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:3.1.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
classpath 'com.google.gms:google-services:3.1.0'
}
}
allprojects {
repositories {
google()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
答案 0 :(得分:0)
com.android.support:
项目和FirebaseUI都没有版本11.4.2依赖项。
这些必须与文件顶部的compileSdk版本匹配。
对于您的用例,
implementation 'com.android.support:appcompat-v7:27.+'
implementation 'com.android.support:design:27.+'
然后,ConstraintLayout,look at the documentation
这一行是正确的,与您的错误不符。
implementation 'com.android.support.constraint:constraint-layout:1.0.2'
11.4.2号码适用于Google Play services, and Firebase only,如果您正在启动新应用,则应相应更新。
例如,
implementation 'com.google.firebase:firebase-core:11.8.0'
implementation 'com.google.firebase:firebase-auth:11.8.0'
Firebase用户界面版must be compatible with those, not the same
