Question

我在Windows 8上使用Android Studio 2.3.2，并且在构建应用程序时出现错误。首先，在启动IDE时的gradle构建期间，我有以下警告：

Warning:WARNING: Dependency org.apache.httpcomponents:httpclient:4.3.6 is 
ignored for debug as it may be conflicting with the internal version 
provided by Android.
Warning:WARNING: Dependency org.apache.httpcomponents:httpclient:4.3.6 is 
ignored for release as it may be conflicting with the internal version 
provided by Android.
Warning:WARNING: Dependency org.apache.httpcomponents:httpclient:4.3.6 is 
ignored for debugAndroidTest as it may be conflicting with the internal 
version provided by Android.
Warning:WARNING: Dependency org.apache.httpcomponents:httpclient:4.3.6 is

provided by Android.
Warning:WARNING: Dependency org.apache.httpcomponents:httpclient:4.3.6 is 
ignored for release as it may be conflicting with the internal version 
provided by Android.

然后在apk版本中有2个警告并且出现此错误：

Warning:WARNING: Dependency org.apache.httpcomponents:httpclient:4.3.6 is 
ignored for release as it may be conflicting with the internal version 
provided by Android.
Warning:WARNING: Dependency org.apache.httpcomponents:httpclient:4.3.6 is

provided by Android.

Answer 1

您需要在“应用”中使用packaginOptions。 build.gradle文件，在buildToolsVersion之后：

packagingOptions {
    exclude 'META-INF/LICENSE'
}

Answer 2

尝试将此添加到 buiild.gradle ，

之所以出现，是因为您没有排除存在于多个依赖项中的packagingOptions { exclude 'META-INF/NOTICE' // will not include NOTICE file exclude 'META-INF/LICENSE' // will not include LICENSE file // as noted by @Vishnuvathsan you may also need to include // variations on the file name. It depends on your dependencies. // Some other common variations on notice and license file names exclude 'META-INF/notice' exclude 'META-INF/notice.txt' exclude 'META-INF/license' exclude 'META-INF/license.txt' }文件

defaultConfig {

             // Enabling multidex support.
             multiDexEnabled true
         }

OR 启用multiDex

const Comp = () => (
<div>
<h3> Test 1 </h3>
<hr/>
<ul className="nav nav-pills">
  <li className="active"><a data-toggle="pill" href="#home">Home</a></li>
  <li><a data-toggle="pill" href="#menu1">Menu 1</a></li>
  <li><a data-toggle="pill" href="#menu2">Menu 2</a></li>
</ul>

<div className="tab-content">
  <div id="home" className="tab-pane fade in active">
    <h3>HOME</h3>
    <p>Some content.</p>
  </div>
  <div id="menu1" className="tab-pane fade">
    <h3>Menu 1</h3>
    <p>Some content in menu 1.</p>
  </div>
  <div id="menu2" className="tab-pane fade">
    <h3>Menu 2</h3>
    <p>Some content in menu 2.</p>
  </div>
</div>
</div>
);

ReactDOM.render( <Comp /> ,
  document.getElementById('root')
);

在Android Studio中构建apk时出现DuplicateFileException
