Android Backup Service requires a filename to backup shared preferences:
public static final String PREFS = "PrefFile";
SharedPreferencesBackupHelper helper = new SharedPreferencesBackupHelper(this, PREFS);
It is clear what to use if filename is given during preferences creation like
public static final String PREF_FILE_NAME = "PrefFile";
SharedPreferences preferences = getSharedPreferences(PREF_FILE_NAME, MODE_PRIVATE);
But I use default shared preferences:
SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(context);
What should I pass as PREFS
value to SharedPreferencesBackupHelper
?
private static String getDefaultSharedPreferencesName(Context context) {
return context.getPackageName() + "_preferences";
}
