I have exactly the same problem with my own developed app, on my own standard non-rooted Samsung Galaxy S with android 2.2.1.
this is my error message, when I do the Editor.commit(): E/ApplicationContext(19228): Couldn't rename file /dbdata/databases/ klwinkel.huiswerk/shared_prefs/klwinkel.huiswerk_preferences.xml to backup file /dbdata/databases/klwinkel.huiswerk/shared_prefs/ klwinkel.huiswerk_preferences.xml.bak I did some investigation, with a "ps" and a "ls -l" on the xml prefs file, with the following result: ps: USER PID PPID VSIZE RSS WCHAN PC NAME app_17 19411 2366 223648 21104 ffffffff 00000000 S klwinkel.huiswerk ls -l --> -rw-rw---- app_107 app_107 292 2011-01-22 20:13 klwinkel.huiswerk_preferences.xml So, this is the proof, that the uid of the prefs file(app_107) and the uid of the app(app_17) are different. The prefs file is from a few days ago, probably I was developing at that time, maybe I removed the app from the phone, I don''t remember. It possibly is a bug in the Samsung android 2.2.1, which does not always delete prefs file when de-installing an app. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
