当我尝试编译我的项目时,我收到此错误消息"Error:(9, 14) error: duplicate class: android.support.v7.appcompat.R".
我正在使用android studio并且我有最新的SDK包。
gradle for the module:
apply plugin: 'com.android.application'
android {
compileSdkVersion 22
buildToolsVersion "21.1.2"
defaultConfig {
minSdkVersion 14
targetSdkVersion 22
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_7
targetCompatibility JavaVersion.VERSION_1_7
}
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
}
dependencies {
compile 'com.android.support:support-v4:22.0.0'
compile files('libs/commons-codec-1.10.jar')
compile "com.android.support:appcompat-v7:22.0.0"
}
项目的Gradle文件:
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:1.1.0'
}
}
allprojects {
repositories {
jcenter()
}
}
这些是项目的gradle文件

移动" compileOptions
"在你的" defaultConfig
"。
我还更新了您的" buildToolsVersion
"。
apply plugin: 'com.android.application'
android {
compileSdkVersion 22
buildToolsVersion "22.0.0"
defaultConfig {
minSdkVersion 14
targetSdkVersion 22
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
compileOptions { // <-- Moved this outside of your defaultConfig
sourceCompatibility JavaVersion.VERSION_1_7
targetCompatibility JavaVersion.VERSION_1_7
}
}
dependencies {
compile files('libs/commons-codec-1.10.jar')
compile 'com.android.support:appcompat-v7:22.0.0' // <-- brings in support-v4
}
