WEBAPIを使用したKivyアプリのAPKファイル化エラー

Question

前提・実現したいこと

python初心者です。
kivyで天気予報のWEBAPIを使ったアプリを作成しています。
デスクトップアプリとしては動作確認済みなのですが、
buildozerを使ってアンドロイド用にAPKファイル化して実機で動かすと、
WEBAPIを使用している部分が表示されなくなってしまいました。
アンドロイド上で動作するようにできないでしょうか
詳しい方のアドバイスをお待ちしています。

試したこと

buildozer.specでインターネットアクセスの許可

補足情報（FW/ツールのバージョンなど）

ここにより詳細な情報を記載してください。

Answer 1

buildozer.specファイルのAndroid認証の部分で、＃を外していなかったことが原因だとわかりました。
