Public methods

canWrite

public static boolean canWrite (Context context)

Checks if the specified app can modify system settings. As of API level 23, an app cannot modify system settings unless it declares the Manifest.permission.WRITE_SETTINGS permission in its manifest, and the user specifically grants the app this capability. To prompt the user to grant this approval, the app must send an intent with the action Settings.ACTION_MANAGE_WRITE_SETTINGS, which causes the system to display a permission management screen.

Parameters
context Context: App context.
Returns
boolean true if the calling app can write to system settings, false otherwise

getConfiguration

public static void getConfiguration (ContentResolver cr, 
                Configuration outConfig)

                String name, 
                float def)

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.

Parameters
cr ContentResolver: The ContentResolver to access.
name String: The name of the setting to retrieve.
def float: Value to return if the setting is not defined.
Returns
float The setting's current value, or 'def' if it is not defined or not a valid float.

getFloat

public static float getFloat (ContentResolver cr, 
                String name)

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 SettingNotFoundException.

Parameters
cr ContentResolver: The ContentResolver to access.
name String: The name of the setting to retrieve.
Returns
float The setting's current value.
Throws
Settings.SettingNotFoundException Thrown if a setting by the given name can't be found or the setting value is not a float.

                String name, 
                int def)

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. The default value will be returned if the setting is not defined or not an integer.

Parameters
cr ContentResolver: The ContentResolver to access.
name String: The name of the setting to retrieve.
def int: Value to return if the setting is not defined.
Returns
int The setting's current value, or 'def' if it is not defined or not a valid integer.

getInt

public static int getInt (ContentResolver cr, 
                String name)

Parameters
cr ContentResolver: The ContentResolver to access.
name String: The name of the setting to retrieve.
Returns
int The setting's current value.
Throws
Settings.SettingNotFoundException Thrown if a setting by the given name can't be found or the setting value is not an integer.

getLong

public static long getLong (ContentResolver cr, 
                String name)

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

Parameters
cr ContentResolver: The ContentResolver to access.
