I would like to write to an Android screen as if it were a simple terminal. I want the output to appear at the time I write it. My application does some cpu intensive churning, writes a bit to the screen and continues. I am using a list adapter for the output. The problem is that the output is not displayed until the activity relinquishes.

I want to run an activity without ANY screen output. The screen should not blink or anything. How?I have an Appwidget. whenever it gets clicked I want to write something to a DB.So, via 'setOnClickPendingIntent' I start an activity that does that and finishes. But, the screen goes black for a short time, while the activity is running. How can I avoid that? Omitting 'setContentView' does not help, neither does a layout without any views. A service instead of an activity could do that, but I cant start a service by setting a 'setOnClickPendingIntent' (or can I?).

View 4 Replies View RelatedIve been raking my brains trying to figure out how to play 720p movies on my HDTV in 16:9 aspect ratio (or 1.78), whereas it would fill the screen of the HDTV nicely just like Niko does it in this thread Video Demo: HTC Evo playback of HD/720p movies over HDMI out. I have a couple of 720p bluray movie files on my PC that i want to encode but now im not even really sure if they are really 720p. When i upload them into handbrake, it says that the source resolution is 1280x544 and the other one 1280x528 with a 2.35 aspect ratio. Doesnt the second number have to be 720 in order to be considered true 720p HD resolution? Everytime i try and change the 528 to 720 on hanbrake, it doesnt let me. And also handbrake doesnt havent an option where you can change the aspect ratio. When i finish encoding, i get the stupid black bars. i realize the video file might have been shot in a 2.35 aspect ratio or whatever but when i play it in VLC it allows me to change it to 16:9. Basically, I want the video to come out in 1280x720, 16:9, 1.78 resolution and aspect ratio as its default settings. This would be much easier if VLC was playable on Android. At the end of the day, im just trying to find out how to watch 720p video on the HDTV in fullscreen or almost fullscreen (i know theres a couple of inches of black bars in 16:9) just like the guy in the thread above.

I have a Pioneer AVH-P3100DVD Car DVD Player with inputs for Auxiliary, TV, and an AV input (as seen here. I'm wondering if there is anyway for me to use one of these inputs to export the screen from my Droid to it. The dvd player is touchscreen, but I don't presume I'll be able to actually control my DX with it, but it would be nice if I could show the navigation on it since it is a 7 inch screen.I also currently have my phone setup with the Motorola car mount and it records video everytime I dock it.So it would be nice if that display would show up on my radio monitor in addition to being on the phone. Or maybe be able to play movies and video clips from my phone on the monitor.Before I invest in cables and trying to take out my radio and plug anything in back there, does anyone know if this is feasible? I've tried to plug it just straight into the auxiliary jack on the front of my stereo but that didn't do anything.I assume it will need to plug into the AV or TV input connections if it does indeed work.

View 2 Replies View RelatedI have a TabActivity, and each Tab corresponds to its own Activity. In one of them, in the onCreate method, I use startActivityForResult to show a dialog (specifically, Bump's BumpAPI activity).
code:...............
The problem is that when the screen orientation changes, it tries to create the tab's activity again which makes another BumpAPI dialog, resulting in multiple stacked on top of each other. Do I have a hook into the started activity to cancel the previous one when the orientation changes?
A workaround seems to be to add a button that when clicked, starts the second activity, but that adds an unnecessary step.
Also, I can't fix the screen orientation for the entire tabActivity because some of them require typing and users may want to use their physical keyboards.
I used Toast to make notification, but it seems it will appear even its activity is not in the current screen and some other activity has been started.I want to check this situation, when the activity is not the current one, I'd not send the Toast notification. But how to do ?

View 2 Replies View RelatedI'm writing an Activity that should take up the entire screen.What happens is that the window title and notification bar are both visible for just a moment when the activity starts up. Then they slide off, leaving my activity with a messed up layout: a blank space the size of the notification bar gets left at the top of the screen, and a little bit of my layout gets cut off at the bottom of the screen.It appears that it's laid out the activity the size of the full screen, but then pushed it down a bit so part of it gets cut off.If I remove either one of the two lines above, everything works correctly and nothing gets cut off. But then I have a title bar or notification bar at the top of the screen, which I don't want.

View 3 Replies View RelatedHow do you set/pass values from one screen (activity) to another? What I have in the R.layout.main view labeled Calculator contains the code for doing calculations. The main.xml contains the layout (view) of the main screen. I have created an options menu which has another screen which shows you setup (R.layout.setup). The dialogsetup.xml contains the layout (view) for it.
When you press the menu button, you get the options menu. If you select "Setup", then it will display the setup screen. Now what I need to do is take the values from the setup screen (radio button and text values) and place them in the main screen so that when you exit the setup screen and go back to the main screen, you can take those values and use them in your main code.
I'm currently developing my first android app, and my first game. I've been developing on a netbook with a CliqXT (HVGA). Things are going well, it renders perfectly on the smaller screen. I knew I'd have some issues when rendering on larger screens, but the issues I'm having are not what I was expecting and I'm kind of stuck.
So basically the game consists of a main SurfaceView which I'm rendering the tiled game world on to. I followed this tutorial to get started, and my structure is still pretty similar except that it calculates the boundries based on the player location:
http://www.droidnova.com/create-a-scrollable-map-with-cells-part-i,654.html
The game also has various buildings the player can enter. Upon entering it launches another activity for that particular building. The building activities are just normal Views with Android UI stuff defined in XML (Buttons, TextViews, etc).
What I expected to happen:
So I expected the the building UIs to render correctly on the larger screen. I specified all dimensions in "dp" and fonts in "sp" in hopes that they'd scale correctly. I expected the actual game tilemap to render generally correctly, but maybe be really tiny due to the higher resolution / dpi. I'm using a very similar function to the tutorial linked above (calculateLoopBorders(), my version is pasted below) to calculate how many tiles to render based on screen height and width (getHeight() and getWidth()).
What is actually happening:
The whole game is just being rendered as if it's HVGA. The tilemap, and the building UIs are just scaled down to the smaller screen size, leaving black borders around the left, right, and bottom (see images).
I would like to perform an activity at the key guard screen, but the only way I can find to do so is to disable the key guard, do my activity, then re enable the key guard. This would be ok if it didn't cause the key guard screen to flash off and on (disable makes it disappear then re enable brings it back). I am wondering how I can perform an activity with it still being displayed? Kinda like how when the alarm goes off it shows a pop-up which is displayed over the key-guard screen?
View 1 Replies View RelatedI know on screen orientation changes activity restarted, but suppose i don't want to restart the activity then what should I do? I had tried it by adding in manifest.xml. android:configChanges="keyboardHidden|orientation"
and override public void onConfigurationChanged(Configuration newConfig) { super.onConfigurationChanged(newConfig); }
But still activity restarted each time when I change screen orientation.
Is it possible to get listed the apps or activity which are actually displayed on the screen of the android mobile. I need to display a text box on some event when no acitivity is displayed, excepting the home screen.
