Android Studio MultiPartEntityBuilder錯誤

Question

我目前正在製作一個應用程序，讓相機和圖庫中的圖像上傳到PHP服務器。但是我的應用程序有問題。我用兩種方法來完成這項任務。第一個是用Base64編碼圖像，然後在httppost中使用UrlEncodedFormEntity。有效。然後我使用了MultiPartEntityBuilder。當我按下上傳按鈕時，應用程序停止。有人能幫助我嗎？我的代碼如下，它有點混亂。對於那個很抱歉。

Answer 1

在您的應用程序gradle這個，添加這些依賴關係：

dependencies { 

    compile group: 'org.apache.httpcomponents' , name: 'httpclient-android' , version: '4.3.5' 
    compile (group: 'org.apache.httpcomponents' , name: 'httpmime' , version: '4.3.5') { 
     exclude module: 'org.apache.httpcomponents:httpclient' 
    } 

} 

此外，添加以下封裝選項：

android { 
    ... 

    packagingOptions { 
     exclude 'META-INF/DEPENDENCIES' 
     exclude 'META-INF/NOTICE' 
     exclude 'META-INF/LICENSE' 
    } 
} 

Answer 2

嘗試很多答案之後，我總結以下直接的解決方案，希望它能幫助你們中的一些人在Android Studio中將MultipartEntityBuilder集成到Gradle配置中。這是通過API版本23.

編輯模塊級buid.gradle文件工作的魅力如下：

android { 
    ... 
    packagingOptions { 
     exclude 'META-INF/DEPENDENCIES' 
     exclude 'META-INF/NOTICE' 
     exclude 'META-INF/LICENSE' 
     exclude 'META-INF/LICENSE.txt' 
     exclude 'META-INF/NOTICE.txt' 
    } 
} 

dependencies { 
    ... 
    compile "org.apache.httpcomponents:httpcore:4.4.1" 
    compile "org.apache.httpcomponents:httpmime:4.3.6" 
}
