How To change System Settings in Android ?
How to make System Changes ?
OR 
How To Change Brightness from my application ? etc.
To make System application or part of it you have to Change certain parameters in Android Settings. Let’s say somehow you have to make some changes in system configuration like display brightness or Ring tone volume from your application. So here is solution require for your application or Part of it. There are number of application in the market who have used these things in application (Tasker etc.). so now you can also integrate it in your application also or using it you can create some awesome apps.
- Create New Application and give name it System Settings and Do next.
- minSdkVersion=»17”
- targetSdkVersion=»17″.
- Give activity name – Main.java and main.xml.
- Go to main.xml and post the below code it contains,
- Two Seek bar for brightness and volume.
- Two Buttons and Two Text view. (Check below screen recording for further layout.)
- onStartTrackingTouch.
- onStopTrackingTouch .
- onProgressChanged.
We can get Seek bar value In onProgressChanged method. Now Paste below code in Main.java class file and make sure you put code as it is.
To make this changes in settings you have to use certain permissions. So go to mainefest file and add these permissions.

Constantspublic static final String ACCELEROMETER_ROTATIONControl 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. public static final String ADB_ENABLEDThis constant was deprecated in API level 3. public static final String AIRPLANE_MODE_ONThis constant was deprecated in API level 17. public static final String AIRPLANE_MODE_RADIOSThis constant was deprecated in API level 17. public static final String ALARM_ALERTPersistent store for the system-wide default alarm alert. See Alsopublic static final String ALWAYS_FINISH_ACTIVITIESThis constant was deprecated in API level 17. 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. public static final String ANDROID_IDThis constant was deprecated in API level 3. public static final String ANIMATOR_DURATION_SCALEThis constant was deprecated in API level 17. 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. public static final String APPEND_FOR_LAST_AUDIBLEAppended to various volume related settings to record the previous values before they the settings were affected by a silent/vibrate ringer mode change. public static final String AUTO_TIMEThis constant was deprecated in API level 17. public static final String AUTO_TIME_ZONEThis constant was deprecated in API level 17. public static final String BLUETOOTH_DISCOVERABILITYDetermines whether remote devices may discover and/or connect to this device. 2 — discoverable and connectable 1 — connectable but not discoverable 0 — neither connectable nor discoverable public static final String BLUETOOTH_DISCOVERABILITY_TIMEOUTBluetooth 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. public static final String BLUETOOTH_ONThis constant was deprecated in API level 3. public static final String DATA_ROAMINGThis constant was deprecated in API level 3. public static final String DATE_FORMATDate format string mm/dd/yyyy dd/mm/yyyy yyyy/mm/dd public static final String DEBUG_APPThis constant was deprecated in API level 17. Name of an application package to be debugged. public static final String DEVICE_PROVISIONEDThis constant was deprecated in API level 3. public static final String DIM_SCREENThis constant was deprecated in API level 17. Whether or not to dim the screen. 0=no 1=yes public static final String DTMF_TONE_WHEN_DIALINGWhether the audible DTMF tones are played by the dialer when dialing. The value is boolean (1 or 0). public static final String END_BUTTON_BEHAVIORWhat happens when the user presses the end call button if they’re not on a call.
