Hi, I'm trying to do a simple test, where the screen turn off and on
several times. something like that:
new CountDownTimer(2000, 1000) {
// boolean change = true;
public void onTick(long millisUntilFinished) {
if(change){
Toast.makeText(getApplicationContext(), "SCREEN OFF!",
Toast.LENGTH_SHORT).show();
change = false;
lp.screenBrightness = 0;
getWindow().setAttributes(lp);
}
else{
Toast.makeText(getApplicationContext(), "SCREEN ON!",
Toast.LENGTH_SHORT).show();
change = true;
lp.screenBrightness = 1;
getWindow().setAttributes(lp);
}
}
public void onFinish() {
}
}.start();
But, when i run the application, the screen turns off and doesnt come
back, so, i though i should disable the keyguard, and i done that wich
this:
//unlock phone
KeyguardManager km = (KeyguardManager)
getSystemService(Context.KEYGUARD_SERVICE);
KeyguardLock mKeyguardLock = km.newKeyguardLock("TEST");
mKeyguardLock.disableKeyguard();
But, using this, i still have to press the power button to turn the
screen on again.... So i tryed to wake up it with this:
//wake phone
PowerManager pm = (PowerManager)
getSystemService(Context.POWER_SERVICE);
PowerManager.WakeLock mWakeLock =
pm.newWakeLock(PowerManager.SCREEN_DIM_WAKE_LOCK |
PowerManager.ACQUIRE_CAUSES_WAKEUP, "TEST");
mWakeLock.acquire();
mWakeLock.release();
But without success.... i tried something with system settings too,
but i dont know how to use it, so i tryed this:
android.provider.Settings.System.putInt(getContentResolver(),
android.provider.Settings.System.SCREEN_BRIGHTNESS_MODE,
android.provider.Settings.System.SCREEN_BRIGHTNESS_MODE_MANUAL);
android.provider.Settings.System.putInt(getContentResolver(),
android.provider.Settings.System.SCREEN_BRIGHTNESS, 1);
Can comeone please help me?
