I'm opening an activity with the following flags
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON
| WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD
| WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED
| WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON
| WindowManager.LayoutParams.FLAG_FULLSCREEN);
Then later on, I want the screen to be able to time out and to turn off automatically.
I tried to remove the flag like this
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON | WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD | WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED);
But it doesn't seem to have any effect. Is there a way to remove this flag dynamically on a displayed activity?
I have implemented a caller ID feature where when the screen is locked it should open the lock and show the popup with the name of the person calling.
this is the code i've added in the onCreate() of the PopupActivity.
getWindow().addFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON |
WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD |
WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED |
WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);
I've also added the permissions
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>
<uses-permission android:name="android.permission.WAKE_LOCK" />
This works fine when the phone is not password/pattern protected.However it shows a black background to the popup window when the device is password/pattern protected disabling the user from attending/rejecting the call.
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON |
WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD |
WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED |
WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON |PixelFormat.TRANSLUCENT);
This seems to be working for me
I am making an Android hybrid application in which my requirements are that as soon as a notification arrives, my app should open and disable all locks. I tried using KeyguardManager(deprecated) but it's working on some devices only. Basically below Lollipop only.
Now I am using this piece of code to achieve the desired result but all in vain.
I have seen many posts regarding the same issue everywhere. FLAG_DISMISS_KEYGUARD is suggested as a replacement for KeyguardManager,
but this is not working for me.
((Activity) mContext).getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN |
WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD |
WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED |
WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON,
WindowManager.LayoutParams.FLAG_FULLSCREEN |
WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD |
WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED |
WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);
Flag dismisse full screen, flag show when local, flag dismisse anoymous input method
Irish of.

Trying to show my Overlay activity over device lock screen - Its Working fine. The problem when my phone ringing | Alarm ringing that time I can see the overlay only. Cancel my overlay then only i can see.. how to avoid that
My code for display activity
Window window = getWindow();
window.addFlags(WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON
| WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED
| WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON
| WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD);
I'm creating an application that uses alarms.
That's how I start alarm activity (in broadcast receiver)
Intent myIntent = new Intent(context, AlarmActivity.class);
myIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK
| Intent.FLAG_ACTIVITY_CLEAR_TASK
| Intent.FLAG_ACTIVITY_CLEAR_TOP);
context.startActivity(myIntent);
When alarm activity is closed, and the application is started again from home button, this activity is launched each time instead of my splash screen, and I have to remove last launched apps from recent apps menu, only then the splash screen is started when the application is launched.
By the way, the above flags are needed to unlock the screen if locked when the alarm is fired, and I have this in my alarm activity:
#Override
public void onAttachedToWindow() {
this.getWindow().setFlags(
WindowManager.LayoutParams.FLAG_FULLSCREEN
| WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD
| WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED
| WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON,
WindowManager.LayoutParams.FLAG_FULLSCREEN
| WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD
| WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED
| WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);
}
Any one has an idea?
