私はもともとカスタムメソッドを使用して写真をアップロードしていましたが、を使用しAsyncTaskて写真をアップロードすることにしProgessBarました. 実行するとAsyncTaskanIllegalArgumentExceptionがスローされますが、理由がわかりません。

private void doFileUpload(){

OnPostExecuteUIスレッドで呼び出されます。メソッドを次のように変更してみてください。

@Override
protected void onPostExecute(String file_url) {
    if (resEntity != null) {
        pDialog.dismiss();
        Log.i("RESPONSE PHOTO",response_str);
        Toast.makeText(getApplicationContext(),"Upload Complete. Check the server uploads directory.", Toast.LENGTH_LONG).show();
    }
}

AsyncTask で新しいスレッドを開始する必要はありません。新しいスレッドを使用せずにすべてのタスクを実行してみてください。（あなたのようにonPostExecute()

AsyncTask を使用すると、UI スレッドを適切かつ簡単に使用できます。このクラスを使用すると、スレッドやハンドラーを操作することなく、バックグラウンド操作を実行し、UI スレッドで結果を公開できます。

非同期タスクは、バックグラウンド スレッドで実行され、その結果が UI スレッドで発行される計算によって定義されます。

理解を深めるためにドキュメントを読んでください。

また、トーストのコンテキスト値を置き換えてみてください

Toast.makeText(News_Edit.this,"Upload Complete. Check the server uploads directory.", Toast.LENGTH_LONG).show();
