使用指令(adb shell)開啟Settings 頁面
am start -n com.android.settings/.Settings

其它好玩的,包名啟動
am start -n com.android.settings/.wifi.WifiStatusTest
am start -n com.android.settings/.SubSettings
am start -n com.android.settings/com.android.settings.RadioInfo
am start -n com.android.settings/.RadioInfo


其它好玩的,意圖啟動
am start -a android.intent.action.MAIN
am start -a android.settings.WIRELESS_SETTINGS
am start -a com.android.settings.APPLICATION_DEVELOPMENT_SETTINGS
am start -a android.settings.WIRELESS_S/ETTINGS
am start -a android.settings.AIRPLANE_MODE_SETTINGS
