Cordova Build Error:Camera Plugin缺少android.support.v4库依赖项

Question

无法构建基于IBM MobileFirst 7.1的Cordova Android应用程序.最近将mobilefirst cli版本升级到7.1.0.00.20180302-0537

添加相机插件(org.apache.cordova.camera)后,android构建失败,并在下面的日志中提到以下错误.看看错误,看起来插件现在需要支持库,但没有将其指示为依赖项.不太确定要解决这个问题需要做些什么.

您可能面临从Android N开始的已知问题.此问题已在iFix 7.1.0.0-MFPF-IF201802160539中修复

或者,尝试此链接中提到的步骤:

准备使用Android平台的Cordova相机插件的项目

步骤是:

• 将android-support-v4.jar文件添加到您的项目中.

  • 在文件资源管理器中,浏览到您的Android SDK目录,Android SDK管理器目录是您下载更新的位置.

  • 如果尚未安装,请在Android环境中安装Android支持存储库.

  • 浏览到extras/android/m2repository/com/android/support/support-core-utils.
  • 选择support-core-utils存储库的版本24.2.0或更高版本.

  • 从support-core-utils-24.2.0.aar包中提取classes.jar文件.如果没有文件存档工具,可以将.aar文件扩展名更改为.zip以提取classes.jar文件.

  • 将classes.jar文件添加到Android平台的libs目录中.

• 更新AndroidManifest.xml文件.

  • 打开platforms/android文件夹中的AndroidManifest.xml文件.

  • 在结束标记内添加以下行:

  <provider android:authorities="{PACKAGE_ID}.provider" android:exported="false" 
   android:grantUriPermissions="true" android:name="android.support.v4.content.FileProvider"> 
   <meta-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="@xml/provider_paths" /> 
  </provider>

其中{PACKAGE_ID}替换为项目的Android Package ID.

• 保存AndroidManifest.xml文件.

更新config.xml文件.

• 打开项目文件夹中的config.xml文件.

• 在标记内,添加以下标记:

   <preference name="applicationId" value="{PACKAGE_ID}"/>
  

其中{PACKAGE_ID}被项目的Android Package ID替换.

• 保存config.xml文件.
