[ERROR] An error occurred while running cordova build android (exit code 1).

　　解決辦法：

執行命令ionic cordova platform add android

　　在platform --> android目錄下找到build.gradle文件，打開並在def promptForReleaseKeyPassword() {...}前加入如下內容：

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

　　緣由：

compile "com.android.support:support-v4:+" 帶+號是指要用最新版本。

force 'com.android.support:support-v4:27.1.0'  添加force強制指定annotations
