Android Full Screen Not Working When Activity Is Launched By A Service

So I am developing an alternate lockscreenapp and I need to prevent clicking the notificationbar so I try to run this app in fullscreenn but when it is calle by a service the notif

Solution 1:

I used full screen before same as your way and had some problems but didn't try launching the activity from service, try to apply full screen this way,

WindowManager.LayoutParamsattrs= getWindow().getAttributes();
attrs.flags |= WindowManager.LayoutParams.FLAG_FULLSCREEN;
getWindow().setAttributes(attrs);

just in case you need to exit full screen, you can do it this way,

WindowManager.LayoutParamsattrs= getWindow().getAttributes();
attrs.flags &= (~WindowManager.LayoutParams.FLAG_FULLSCREEN);
getWindow().setAttributes(attrs);

give it a shot, good luck!

Solution 2:

It seems that this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD); causes the issue.

Someone else suggests to delay that call: See Activity doesn't show in full screen.
