私はこの問題を解決するために立ち往生して夢中になっていますが、私には運がありません。私は以前にこの質問をしたときにSOメンバーが私に与えたすべてのガイドラインを試しました:(回答してくれたすべての人に感謝します。私はそれを解決するためにたくさん検索しますが、最後の希望は成功しません。このJSONParsingを解決できますか？PHPからデータを投稿し、Android EditTextボックスにデータを取得したいのですが、コーディングしましたが、初日から存在し、まだ解決されていない問題があります。エミュレーターと電話で異なるLogCatエラーが発生しました。私はあなたに私のjavaコードとLogCatエラーを提起しました。どんなガイドも私にとって貴重です。
私のJavaコードは、エラーが発生した場所です。
