Android アプリで http 投稿リクエストに問題があります。
libcore.io.ErrnoException: socket failed: EACCES (Permission denied)
私のアプリは、1 つの Android フォンを除くほとんどの Android デバイスで正常に動作します。私のアプリは、その電話で http を介してインターネットに接続できません。ただし、ブラウザーなどの他のアプリは、その Android フォンで適切に実行できます。
について質問があり、アプリで許可EACCES (Permission denied)を確認しました<uses-permission android:name="android.permission.INTERNET" />が、問題はありません。
スタックトレースは次のとおりです。
