Field

int	MODE_PRIVATE File creation mode: the default mode, where the created file can only be accessed by the calling application (or all applications sharing the same user ID).
int	MODE_WORLD_READABLE File creation mode: allow all other applications to have read access to the created file.
int	MODE_WORLD_WRITEABLE File creation mode: allow all other applications to have write access to the created file.
int	MODE_APPEND File creation mode: for use with #openFileOutput , if the file already exists then write data to the end of the existing file instead of erasing it.
int	MODE_MULTI_PROCESS SharedPreference loading flag: when set, the file on disk will be checked for modification even if the shared preferences instance is already loaded in this process.
int	BIND_AUTO_CREATE Flag for #bindService : automatically create the service as long as the binding exists.
int	BIND_DEBUG_UNBIND Flag for #bindService : include debugging help for mismatched calls to unbind.
int	BIND_NOT_FOREGROUND Flag for #bindService : don't allow this binding to raise the target service's process to the foreground scheduling priority.
int	BIND_ABOVE_CLIENT Flag for #bindService : indicates that the client application binding to this service considers the service to be more important than the app itself.
int	BIND_WAIVE_PRIORITY Flag for #bindService : don't impact the scheduling or memory management priority of the target service's hosting process.
int	BIND_IMPORTANT Flag for #bindService : this service is very important to the client, so should be brought to the foreground process level when the client is.
int	BIND_ADJUST_WITH_ACTIVITY Flag for #bindService : If binding from an activity, allow the target service's process importance to be raised based on whether the activity is visible to the user, regardless whether another flag is used to reduce the amount that the client process's overall importance is used to impact it.
