Aug 2, 2010I am looking for a way in which I can detect any tap on the screen (not just in my app), I don't mind not having the information of what the tap was (control/letter), just the fact that a tap was made will suffice for me for now. Is there any possible way to achieve this?

Apr 4, 2010As mentioned in a previous question, I am having difficulty intercepting all android.intent.action.SCREEN_ON events without a long-lived service (discouraged). I may be able to work around the need if I can simply work out when the screen is on at any given time, in the service.

Android :: How To Detect That Wi-Fi Turns Off While Screen Is Off
Apr 18, 2010I recently bought a HTC Desire which I've become exceedingly fond of.I've read (and been told by a colleague who owns a HTC Legend) that wifi should automatically turn off while the screen is off to conserve battery. I have the impression that I should be able to see the wifi icon turn on as I turn on the screen and unlock the phone. However, I haven't noticed that happening: The icon seems to just be on always.I have then tried observing my router's DHCP table when the the screen is off, but I haven't observed the entry for my phone disappearing (and I don't really know how much time has to pass before the table not showing my phone.Are there any settings that can cause this behaviour? What about programs? I current use smart monitor to log data usage as well as locale (using a SSID plugin and not the locale "location" condition). The only services I can see apart from those I think are OS services, are the ones for locale, smart monitor lite and the SSID plugin.

Sep 28, 2010I'm writing a customized view similar to Grid which will be used to hold a large amount of images. I'm using ImageButton to display the images, and I only want to load images onto the buttons once they are on the screen (and just display a static background image when they are not). The reason for it is that I'm fetching images from some back-end service and I only want to fetch them when the buttons are on the screen.To do that, I'd like to know if the widget is on the screen. Is it possible to detect if a widget like button is on/off screen? If not, any suggestions on how to achieve what I'm trying to do?

View 10 Replies View RelatedAndroid : Detect Finger Going Off Screen?
Jan 3, 2010I have a motion listener to detect finger down, finger drag, and finger up. I start my action at finger down and finish my action at finger up. When the action is finished, I store it in a stack for allowing undo. My problem is that if I don't get a finger up event, I can't finish my action to add it to the stack for undo.
How can I detect that the user's finger has left the screen?
I tried using the emulator to see if getEdgeFlags() ever returned anything useful, and the result was always 0.
Basically, if a finger leaves the screen, then nothing is touching the screen anymore and I would like to detect that as a finger up event. How can I do this?

View 1 Replies View RelatedAndroid :: Detect / Intercept Screen Turning Off
Nov 27, 2009Is there any way where I can detect that the screen is about to turn off, so I can do some work *before* it happens?I need this to work around bug 3755: OpenGL apps sometimes crash when the screen gets turned off because they don't get surfaceDestroyed /surfaceCreated() events. Simply put, I need to shut down OpenGL before the phone has a chance to detach the GPU. The only events I seems to be getting when the screen turns off are onPause() and onWindowFocusChanged both of which turn up *after* the GPU detaches, by which time it's too late.

General :: Screen Will Not Detect Touch?
Dec 3, 2012I was using my phone (droid 3) and the app I was using force closed, my phone lagged for a few seconds and then I just put it down so it could catch up. While waiting the screen timed out and when I went to use it I could not unlock it. I can press the button on top and it will turn the screen on or off, and if I hold it it will bring up the power off menu. I tried to call it, and it went through. I got the normal screen to answer it, but I could not answer it. After I hung up I got the notification for a missed call. Everything seems to be working, my screen just does not respond to a touch. What should I do?
