                                 "navigation", "screenLayout", "fontScale", "uiMode",
                                 "orientation", "screenSize", "smallestScreenSize"]
mcc:The IMSI mobile country code (MCC) has changed — a SIM has been detected and updated the MCC.
IMSI(國際移動用戶識別碼)發生改變，檢測到SIM卡，或者更新MCC
mnc:The IMSI mobile network code (MNC) has changed — a SIM has been detected and updated the MNC.
        IMSI網絡發生改變,檢測到SIM卡，或者更新MCC
locale:The locale has changed — the user has selected a new language that text should be displayed in.
語言發生改變，用戶選擇了一個新的語言，文字應該重新顯示
touchscreen:The touchscreen has changed. (This should never normally happen.)
觸摸屏發生改變，這通常是不應該發生的
keyboard:The keyboard type has changed — for example, the user has plugged in an external keyboard.
鍵盤類型發生改變，例如，用戶使用了外部鍵盤
keyboardHidden:The keyboard accessibility has changed — for example, the user has revealed the hardware keyboard.

navigation:The navigation type (trackball/dpad) has changed. (This should never normally happen.)
導航發生改變，（這通常不應該發生）
screenLayout：The screen layout has changed — this might be caused by a different display being activated.
屏幕的佈局發生改變，這可能導致激活不同的顯示
fontScale：The font scaling factor has changed — the user has selected a new global font size.


uiMode：The user interface mode has changed — this can be caused when the user places the device into a desk/car dock or when the the night mode changes. See UiModeManager. Introduced in API Level 8.
orientation：The screen orientation has changed — the user has rotated the device.
Note: If your application targets API level 13 or higher (as declared by the minSdkVersion and targetSdkVersion attributes), then you should also declare the "screenSize" configuration, because it also changes when a device switches between portrait and landscape orientations.


screenSize：The current available screen size has changed. This represents a change in the currently available size, relative to the current aspect ratio, so will change when the user switches between landscape and portrait. However, if your application targets API level 12 or lower, then your activity always handles this configuration change itself (this configuration change does not restart your activity, even when running on an Android 3.2 or higher device).


smallestScreenSize：The physical screen size has changed. This represents a change in size regardless of orientation, so will only change when the actual physical screen size has changed such as switching to an external display. A change to this configuration corresponds to a change in the smallestWidth configuration. However, if your application targets API level 12 or lower, then your activity always handles this configuration change itself (this configuration change does not restart your activity, even when running on an Android 3.2 or higher device).
Added in API level 13.
