Question

我成功导入了ActionBarActivity的lib，但是当我构建项目时，它得到以下错误帮助我。

Compilation failed to complete

错误：

    Program type already present: android.support.v7.app.ActionBar$LayoutParams
Message{kind=ERROR, text=Program type already present: android.support.v7.app.ActionBar$LayoutParams, sources=[Unknown source file], tool name=Optional.of(D8)}

这是我的Gradle文件代码：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "com.hsdsolution.hamza.sqliteimplementation"
        minSdkVersion 14
        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(include: ['*.jar'], dir: 'libs')
    implementation 'com.android.support:appcompat-v7:27.1.1'
   // implementation 'com.android.support:design:27.1.1'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    implementation files('libs/android-support-v4.jar')
    implementation files('libs/android-support-v7-appcompat.jar')
}

您要为appcompat-v7添加3次依赖关系...

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

删除文件libs/android-support-v7-appcompat.jar，它应该生成。

程序类型已经存在：android.support.v7.app.ActionBar $ LayoutParams
