虽然有许多类似的问题,我检查了所有答案,但没有一个适用于我!
以下是编译代码时出现的错误:
Program type already present: android.support.v4.app.BackStackRecord$Op Message{kind=ERROR, text=Program type already present: android.support.v4.app.BackStackRecord$Op, sources=[Unknown source file], tool name=Optional.of(D8)}
这里是我的gradle文件:
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:3.1.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
maven {
url "https://jitpack.io"
}
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
应用程序:
apply plugin: 'com.android.application'
android {
compileSdkVersion 27
defaultConfig {
applicationId "com.alcantara.bugismart"
minSdkVersion 15

versionCode 1

}

proguardFiles getDefaultProguardFile('proguard-android.txt'),

}
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:27.1.1'
