我添加了下面的依赖项，但它仍然显示相同的错误

dependencies {
compile 'com.google.android.gms:play-services:+'
compile 'org.apache.httpcomponents:httpclient:4.2.6'
compile 'org.apache.httpcomponents:httpmime:4.2.6'
compile files('libs/core.jar')
}

Answer 1

您需要初始化useLibrary'org.apache.http.legace'

请检查HttpClient不会在Android Studio中导入

android {
    compileSdkVersion 23
    buildToolsVersion '23.0.1' 


    defaultConfig {
        minSdkVersion // set yours 
        targetSdkVersion 23
        versionCode 11 //Yours
        versionName "0.1" // Yours
    }

dependencies {
compile 'com.google.android.gms:play-services:7.8.0'
compile 'org.apache.httpcomponents:httpmime:4.2.6'
compile 'org.apache.httpcomponents:httpclient:4.5'
compile files('libs/core.jar')
}

然后清理-重建-重新启动-同步项目。
