Hi everybody.
I use Android SDK 1.5
I want to set system screen bright but not activity because I run as
service.
I tried
android.provider.Settings.System.putInt(getContentResolver(),
android.provider.Settings.System.SCREEN_BRIGHTNESS,0);
but it's not working
the screen bright has no any change
and I tried
WindowManager.LayoutParams lp = getWindow().getAttributes();
lp.screenBrightness = 1.0f;
getWindow().setAttributes(lp);
it can work in avtivity but in service there's no getWindow() function
so I can't use this method
so how can i adjust screen bright immediate in service?(i want to
adjust screen bright for all system not only in activity)
By the way , in PowerManager Class there's a goToSleep() function but
when i call this function,it happen SecurityException ,but i already
add <uses-permission android:name="android.permission.DEVICE_POWER"/
> to AndroidManifest.xml.
I have search in android develop group and there has same issues ,
but i don't know how to solve.
Thanks.
