Settings.System

Control whether the accelerometer will be used to change screen orientation. If 0, it will not be used unless explicitly requested by the application; if 1, it will be used by default unless explicitly disabled by the application.

Persistent store for the system-wide default alarm alert.

If 1, the activity manager will aggressively finish activities and processes as soon as they are no longer needed. If 0, the normal extended lifetime is used.

Scaling factor for Animator-based animations. This affects both the start delay and duration of all such animations. Setting to 0 will cause animations to end immediately. The default value is 1.

Determines whether remote devices may discover and/or connect to this device.

Type: INT

Bluetooth discoverability timeout. If this value is nonzero, then Bluetooth becomes discoverable for a certain number of seconds, after which is becomes simply connectable. The value is in seconds.

Date format string mm/dd/yyyy dd/mm/yyyy yyyy/mm/dd

Name of an application package to be debugged.

Whether or not to dim the screen. 0=no 1=yes

CDMA only settings DTMF tone type played by the dialer when dialing. 0 = Normal 1 = Long

Whether the audible DTMF tones are played by the dialer when dialing. The value is boolean (1 or 0).

What happens when the user presses the end call button if they're not on a call.
Values:
0 - The end button does nothing.
1 - The end button goes to the home screen.
2 - The end button puts the device to sleep and locks the keyguard.
3 - The end button goes to the home screen. If the user is already on the home screen, it puts the device to sleep.

Scaling factor for fonts, float.

Whether the haptic feedback (long presses, ...) are enabled. The value is boolean (1 or 0).

Determines which streams are affected by ringer mode changes. The stream type's bit should be set to 1 if it should be muted when going into an inaudible ringer mode.

Determines which streams are affected by mute. The stream type's bit should be set to 1 if it should be muted when a mute request is received.

A formatted string of the next alarm that is set, or the empty string if there is no alarm set.

Persistent store for the system-wide default notification sound.

Persistent store for the system-wide default ringtone URI.

If you need to play the default ringtone at any given time, it is recommended you give DEFAULT_RINGTONE_URI to the media player. It will resolve to the set default ringtone at the time of playing.

The screen backlight brightness between 0 and 255.

Control whether to enable automatic brightness mode.

SCREEN_BRIGHTNESS_MODE value for automatic mode.

SCREEN_BRIGHTNESS_MODE value for manual mode.

The amount of time in milliseconds before the device goes to sleep or begins to dream after a period of inactivity. This value is also known as the user activity timeout period since the screen isn't necessarily turned off when it expires.

Whether the setup wizard has been run before (on first boot), or if it still needs to be run. nonzero = it has been run in the past 0 = it has not been run in the past

Control whether the process CPU usage meter should be shown.

Whether the sounds effects (key clicks, lid open ...) are enabled. The value is boolean (1 or 0).

Setting to enable Auto Caps in text editors. 1 = On, 0 = Off

Setting to enable Auto Punctuate in text editors. 1 = On, 0 = Off. This feature converts two spaces to a "." and space.

Setting to enable Auto Replace (AutoText) in text editors. 1 = On, 0 = Off

Setting to showing password characters in text editors. 1 = On, 0 = Off

Display times as 12 or 24 hours 12 24

Scaling factor for activity transition animations. Setting to 0 will disable window animations.

Default screen rotation when no other policy applies. When ACCELEROMETER_ROTATION is zero and no on-screen Activity expresses a preference, this rotation value will be used. Must be one of the Surface rotation constants.

Whether vibrate is on for different events. This is used internally, changing this value will not change the vibrate. See AudioManager.

Whether the phone vibrates when it is ringing due to an incoming call. This will be used by Phone and Setting apps; it shouldn't affect other apps. The value is boolean (1 or 0). Note: this is not same as "vibrate on ring", which had been available until ICS. It was about AudioManager's setting and thus affected all the applications which relied on the setting, while this is purely about the vibration setting for incoming calls.

If 1, when launching DEBUG_APP it will wait for the debugger before starting user code. If 0, it will run normally.

Name of activity to use for wallpaper on the home screen.

If using static IP, the primary DNS's IP address.

Example: "192.168.1.1"

If using static IP, the secondary DNS's IP address.

Example: "192.168.1.2"

If using static IP, the gateway's IP address.

Example: "192.168.1.1"

The static IP address.

Example: "192.168.1.51"

If using static IP, the net mask.

Example: "255.255.255.0"

Whether to use static IP and other static network attributes.

Set to 1 for true and 0 for false.

Scaling factor for normal window animations. Setting to 0 will disable window animations.

The content:// style URL for this table

A Uri that will point to the current default alarm alert at any given time.

A Uri that will point to the current default notification sound at any given time.

A Uri that will point to the current default ringtone at any given time.

If the current default ringtone is in the DRM provider and the caller does not have permission, the exception will be a FileNotFoundException.

An app can use this method to check if it is currently allowed to write or modify system settings. In order to gain write access to the system settings, an app must declare the WRITE_SETTINGS permission in its manifest. If it is currently disallowed, it can prompt the user to grant it this capability through a management UI by sending an Intent with action ACTION_MANAGE_WRITE_SETTINGS.

Convenience function to read all of the current configuration-related settings into a Configuration object.

Convenience function for retrieving a single system settings value as a floating point number. Note that internally setting values are always stored as strings; this function converts the string to an float for you. The default value will be returned if the setting is not defined or not a valid float.

Convenience function for retrieving a single system settings value as a float. Note that internally setting values are always stored as strings; this function converts the string to a float for you.

This version does not take a default value. If the setting has not been set, or the string value is not a number, it throws Settings.SettingNotFoundException.

Convenience function for retrieving a single system settings value as an integer. Note that internally setting values are always stored as strings; this function converts the string to an integer for you.

Construct the content URI for a particular name/value pair, useful for monitoring changes with a ContentObserver.

Convenience function to write a batch of configuration-related settings from a Configuration object.

Convenience function for updating a single settings value as a floating point number. This will either create a new entry in the table if the given name does not exist, or modify the value of the existing row with that name. Note that internally setting values are always stored as strings, so this function converts the given value to a string before storing it.
