さらに処理するためにSDカードからPHPサーバーにファイルをアップロードする必要があるアプリケーションを作成していますが、logcatをアップロードしようとすると、次のエラーが表示されます：java.net.ConnectException：/10.0.2.2（ポート8080）への接続に失敗しました：接続に失敗しました：ETIMEDOUT（接続がタイムアウトしました）。私のJavaコードは以下の通りです。

    } catch (MalformedURLException ex) {

    }

    catch (IOException ioe) {
        Log.e(Tag, "error: " + ioe.getMessage(), ioe);
    }


    try {
        BufferedReader rd = new BufferedReader(new InputStreamReader(conn
                .getInputStream()));
        String line;
        while ((line = rd.readLine()) != null) {

        rd.close();

    } catch (IOException ioex) {
        Log.e("Note Pad", "error: " + ioex.getMessage(), ioex);
    }
}
}

私のPHPファイルは次のとおりです。

<?php
// Where the file is going to be placed 
 $target_path = "admin/";

 /* Add the original filename to our target path.  
  Result is "uploads/filename.extension" */
 $target_path = $target_path . basename( $_FILES['uploadedfile']['name']); 

 if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
  echo "The file ".  basename( $_FILES['uploadedfile']['name']). 
  " has been uploaded";
  chmod ("uploads/".basename( $_FILES['uploadedfile']['name']), 0644);
} else{
 echo "There was an error uploading the file, please try again!";
 echo "filename: " .  basename( $_FILES['uploadedfile']['name']);
 echo "target_path: " .$target_path;
}
?>

誰かが私にどこが間違っているかをできるだけ早く教えてもらえますか？ありがとう。

IPを扱っているからこそ、それが起こっていると思います。ドメイン名を使用してみてください。
