android - Android 強制終了を使用して画像をアップロードしますが、まだ機能しています

Question

基本的に、写真を正常に追加できますが、成功したメッセージをトーストする代わりに、強制的に閉じるダイアログが表示されるだけです。または、画像が大きすぎる場合は、「仮想メモリの過負荷……」と表示され、強制的に閉じられる問題を知る必要があります。漏れた窓？

私はこれの初心者ですが、そのエラーの意味を教えてください。

問題：

以下の例外が発生しています:

原因: java.lang.RuntimeException: Looper.prepare() を呼び出していないスレッド内でハンドラを作成できません

以下のコードのためだけに：

//if the success is equals to 1
if(success == 1){

      //toast successful message to user
      Toast.makeText(getApplicationContext(), json.getString(TAG_MESSAGE) , Toast.LENGTH_SHORT).show();
 }else{
      //toast error message to user
      Toast.makeText(getApplicationContext(), json.getString(TAG_MESSAGE) , Toast.LENGTH_SHORT).show();
 }

なぜこの例外が発生するのですか?

非 UI スレッドからの doInBackground() メソッドから Toast メッセージを表示しようとしています。

解決：

を使用して実行時間の長いプロセスを実行中に UI を表示/更新する場合はいつでもAsyncTask、次のいずれかのソリューションを実装できます。

onPostExecute()メソッド内の UI を更新します。// 標準的な方法
内部の UI を実装runOnUiThread()および更新するdoInBackground()

ログのように：

原因: java.lang.RuntimeException: Looper.prepare() を呼び出していないスレッド内でハンドラを作成できません

ToastMessages from doInBackgroundmethod means from non-ui Threadを表示しようとしているためです。このエラーを回避するには、常に UI スレッドで実行さsuccessれるdoInBackgroundに戻る必要があります。onPostExecute

//create ending process 
protected void onPostExecute(String string) {

    // dismiss the dialog once got all details  
    pDialog.dismiss();
    //show Toast message here....
}
