Issue while creating a debug build ionic.

まず ionic cordova build android --debug を再現し、生成された Android プロジェクトで報告された :app:processDebugResources の失敗を調査します。ペイロードは merged_manifests\debug\AndroidManifest.xml と不足している xml/network_security_config リソースを指しています；完了条件は、CLI と生成されたプロジェクトのどちらがこの失敗の原因かを特定することです。

I am creating a debug build for android.

• ionic cordova platform add android = successfully executed
• ionic cordova build android --debug = throwing error

Steps to Reproduce:
