Отладка приложений Android на реальном устройстве

Question

Я тестирую свое последнее приложение для Android на реальном устройстве, и он падает на втором экране.

Протестировано на симуляторе, оно отлично работает.

Это сообщение отладки, когда он выходит из строя .....

Любая помощь приветствуется, чтобы узнать, где начать решать эту проблему.

Answer 1

Я думаю, что проблема заключается в:

adapter = new Cursos_ListViewAdapter(Cursos_MainActivity.this, arraylist); 
     // Set the adapter to the ListView 
     listview.setAdapter(adapter); 

Я понятия не имею, что находится в вашем адаптере, но обычно вы имеете дело там с видом.

Не забывайте, что «onPostExecute» все еще находится в другом потоке, и вы пытаетесь работать с видом от основной нити/деятельности ...

Лучшее решение для таких вещей, как это передать в AsyncTask некоторый интерфейс, и когда это будет сделано, AsyncTask передаст данные обратно активности.

Это также намного ближе к SOLID. AsyncTask должен получить данные и передать их. Адаптер должен отобразить полученные данные.

Answer 2

ваш mProgressDialog утечка памяти.

попробовать это

mProgressDialog = new ProgressDialog(this.getApplicationContext());
