• 解决方法：

  1. 执行命令ionic cordova platform add android

  如已经执行过（已经添加过android平台）则进入下一步

  2.在platform --> android目录下找到build.gradle文件，打开并在def promptForReleaseKeyPassword() {...}函数前加入以下内容：

  configurations.all {
    resolutionStrategy {
        force 'com.android.support:support-v4:27.1.0'
    }
  }
  

  如图：

  3.执行ionic cordova build android

  这时候已经可以成功打包android了

其他

• 该方法需要在每次执行ionic cordova platform rm android，ionic cordova platform add android重新添加android平台支持后修改一次build.gradle文件
• 该方法为暂时性的解决方案，最终解决还等android更新support - v4的最新支持库
