java– 程序类型已存在错误

概述虽然存在许多类似的问题,但我检查了所有答案,但没有一个对我有效！这是编译代码时我遇到的错误：Programtypealreadypresent:android.support.v4.app.BackStackRecord$OpMessage{kind=ERROR,text=Programtypealreadypresent:android.support.v4.app.BackStackRecord$Op,s

虽然存在许多类似的问题,但我检查了所有答案,但没有一个对我有效！

这是编译代码时我遇到的错误：

Program type already present: androID.support.v4.app.BackStackRecord$OpMessage{kind=ERROR, text=Program type already present: androID.support.v4.app.BackStackRecord$Op, sources=[UnkNown source file], tool name=Optional.of(D8)}

这是我的gradle文件：

apply plugin: 'com.androID.application'androID {   compileSdkVersion 27   defaultConfig {       applicationID "com.narsun.grocery"       minSdkVersion 21       targetSdkVersion 27       versionCode 1       versionname "1.0"       multIDexEnabled true       testInstrumentationRunner "androID.support.test.runner.AndroIDJUnitRunner"   }   buildTypes {       release {           MinifyEnabled false           proguardfiles getDefaultProguardfile('proguard-androID.txt'), 'proguard-rules.pro'       }   }   packagingOptions {       exclude 'meta-inf/DEPENDENCIES.txt'       exclude 'meta-inf/liCENSE.txt'       exclude 'meta-inf/NOTICE.txt'       exclude 'meta-inf/NOTICE'       exclude 'meta-inf/liCENSE'       exclude 'meta-inf/DEPENDENCIES'       exclude 'meta-inf/notice.txt'       exclude 'meta-inf/license.txt'       exclude 'meta-inf/dependencIEs.txt'       exclude 'meta-inf/LGPL2.1'   }}dependencIEs {   implementation filetree(dir: 'libs', include: ['*.jar'])   androIDTestImplementation('com.androID.support.test.espresso:espresso-core:2.2.2', {       exclude group: 'com.androID.support', module: 'support-annotations'   })   implementation 'com.androID.support:appcompat-v7:27.1.0'   implementation 'com.androID.support:cardvIEw-v7:27.1.0'   implementation 'com.androID.support:design:27.1.0'   implementation 'com.androID.support.constraint:constraint-layout:1.0.2'   implementation 'com.github.sd6352051.niftydialogeffects:niftydialogeffects:1.0.0@aar'   implementation 'com.squareup.picasso:picasso:2.5.2'   implementation 'com.squareup:androID-times-square:1.6.5@aar'   implementation 'com.daimajia.slIDer:library:1.1.5@aar'   implementation 'com.astuetz:pagerslIDingtabstrip:1.0.1'   implementation 'de.hdodenhof:circleimagevIEw:2.2.0'   implementation 'com.github.myinnos:AwesomeImagePicker:1.0.2'   implementation 'com.github.ratty3697:androID-smart-animation-library:1.6'   implementation 'com.github.zcweng:switch-button:0.0.3@aar'   implementation 'com.github.JakeWharton:VIEwPagerIndicator:2.4.1'   implementation 'com.Google.androID.exoplayer:exoplayer:2.6.1'   implementation 'pl.droIDsonroIDs.gif:androID-gif-drawable:1.2.10'   implementation 'com.androID.support:multIDex:1.0.3'   testImplementation 'junit:junit:4.12'}

你可以告诉我是否还有其他东西需要补充,以了解我在做什么或我错在哪里.

解决方法:

包版本可能不兼容.尝试降级com.androID.support包,即appcompat

所以 – 实现’com.androID.support:appcompat-v7:27.0.1′
