私は物事を共有するのに役立つモバイルアプリを開発しました。ユーザは自分が送信していることについての情報を提供しなければならず、オブジェクトの画像を追加することができる。だから、私はcordova file、camera、fileTransfertプラグインを使いました。私がテストしたほとんどのデバイスでうまくいきましたが、他の携帯電話ではそうではありませんでした。いくつかのテストとこれらの電話機に関する調査を行っているうちに、私はFileTransfertのupload（）メソッドを使ってオンラインサーバーに画像を送信すると、画像が保存されているフォルダに到達できないように思えます。ここに私のコードのサンプルがあります。私がリグであることを確認し、その電話機をプラットフォーム上に写真を投稿できるようにする方法を教えてください。オブジェクトのアップロード（）オブジェクトが一部のアンドロイドデバイスで動作しないFileTransfert
