screensaver

I'd like to disable screen saver while my appliction is running. How it can be done? Where is the best place to disable / enable the screen saver? in the first activity? in the application.java? The wake lock permission must be specified in the manifest. <uses-permission android:name="android.permission.WAKE_LOCK" /> Then in the activity use the following to keep the screen on while the activity is running. getWindow().addFlags(LayoutParams.FLAG_KEEP_SCREEN_ON); Remember that unnecessarily keeping the screen on unnecessarily drains power from the user's device. You must also add: import

On my Galaxy Nexus, I can tap this button in system preferences to start my currently selected daydream. Is there a way to reproduce this functionality in an app via Intent? I don't have a daydream service, but I would like to allow the user to start their preferred daydream. Jacob Tabak Edit 9/22/2014: This does not work on some Samsung phones I figured out how to do this by digging through some Android source code. final Intent intent = new Intent(Intent.ACTION_MAIN); intent.setClassName("com.android.systemui", "com.android.systemui.Somnambulator"); startActivity(intent); Sample app

Does anyone have a link or document on how to write a screensaver for Linux? Here's some info on xscreensaver that you may find of use: xscreensaver also there's an FAQ here . There's a simple tutorial here too: simplesquares (from the first link) This might be of interest to you: http://www.jwz.org/xscreensaver/faq.html#writing-savers it's from the xscreensavers homepage, it's sort of the de facto screensaver Google "xscreensaver", and you can learn from its code, rather than starting from scratch. 来源： https://stackoverflow.com/questions/1124817/how-to-develop-linux-screen-saver

I wrote a simple alarm-clock style application that I run on my (jailbroken) Nook Simple Touch (aka NST), under Android 2.1. When the scheduled alarm time arrives, my application needs to wake up the NST and display a page of HTML content. I use AlarmManager to get a callback at the right time, and it seems to work as expected -- almost. The problem occurs when enough idle time has passed that the NST has activated its lock-screen mode (i.e. it is auto-displaying a caricature of a famous author). I can't find a programmatic way to dismiss the lock-screen so that my HTML content will be visible

I have a working screensaver and would like to figure out how I can control the name Windows displays in the screensaver drop down list. Currently it all seems to be based on the filename but I know that can't be the case. Here's what I've tried and the results: Filename: CC.Votd.scr ScreenSaver Name: Cc Filename: CC Votd.scr ScreenSaver Name: Cc Votd I'd like to have the file be named CC.Votd.scr and have the screensaver name display as CC.Votd (capitalization is important to me so even CC Votd would be ok :-)) I'm pretty sure this is possible because the Photos screensaver is

I'd like to invoke the user's screen saver if such is defined, in a Windows environment. I know it can be done using pure C++ code (and then the wrapping in C# is pretty simple), as suggested here . Still, for curiosity, I'd like to know if such task can be accomplished by purely managed code using the dot net framework (version 2.0 and above), without p/invoke and without visiting the C++ side (which, in turn, can use windows API pretty easily). I've an idea, I'm not sure how consistently this would work, so you'd need to research a bit I think, but hopefully it's enough to get you started. A

How to install (register) screensaver programmatically? AFAIk there are two ways: Permanent registration by copying it to a location that windows searches, such as System32 . But don't hardcode "C:\Windows\System32". You need to query the system to find out where the system directory is. Calling the Install action on the .scr file, which results in temporary activation. But the screensaver will disappear once another has been selected and the dialog restarted. But this is from Win95 times, so it's possibly outdated. I see three ways to call install : ShellExecute(Ex) using the install verb
