Tworzę aplikację dla systemu Android, która po prostu wybiera obraz z karty SD (Galeria telefonu) i zapisuje go na dysku Google. Zrobiłem dużo wysiłku, wziąłem pomoc z kodu dostarczonego przez programistów Googlejazda szybki start. Zrobiłem formant Button w moim pliku main.xml, po kliknięciu tego przycisku zajmie on wnętrze galerii telefonu i kiedy wybiorę zdjęcie nic się nie dzieje

To jest Log Cat z mojego zaćmienia IDE
