Apps Change android system settings by code.

[c2tarun]

Hi friends,

Can anyone tell me about some tutorial for changing android system settings by code.
System Settings like:
Ringtones
Vibration
Volume
Brightness
etc

If anyone please tell me the names of the classes in which I have to look into, it will also be helpful.

Thanks

I tried posting a similar thread on xda developers forum : Change android system settings by code. - xda-developers but nobody replied

I tried searching in docs and found about Ringtone Manager, but when I tried to change ringtone using RingtoneManager.setActualDefaultRingtoneUri nothing happened. Need help. please reply.

have you tried the Settings.System class ? Or this one : Can I update an Android provider.Settings.System value?

I was also having some problem in writing settings by Settings.System, I scanned docs and found methods like putString and many else. I'll go home and try today. It work or didn't work I'll reply here tomorrow.

I tried using Settings.System and changed SCREEN_BRIGHTNESS value to the value of a seek bar. But the problem is value is not changing as I am changing the value from seek bar. It is changing after the application is getting closed and mobile is getting locked, and when I am unlocking the phone, I am seeing the new brightness.
Why so?
