Qvga Screen Hides Some Pixels - Solution For This

I have a problem with missing pixels on qvga screen on android (all versions including 2. 2). The original problem was with linearlayout and margin="1px". It was ok on the normal screen but on qvga there was sometimes no space between gui controls, like if margin="0px" and not 1px. So i tried to make the example simple (to be sure that it is not a linearlayout bug), i have just put transparent (height = 10px) and white (height = 1px) images into imageviews into the main screen. 25% of the white images are not shown on the qvga screen. The behaviour on the normal screen is ok. The screenshots are from the emulator but the problem exists on real devices too.

See screenshots on my web page.

Is it an android bug? Can i do anything with it? Note that my original problem was with linearlayout and margin="1px". Is there something like margin="1px_that_is_not_hidden"? (Pt, dp, dip, . Don't seem to be solution

Pixels Of Background Image Looks Blurry When Using Its Attribute For Layout / How To Do This

When i am using the background attribute for a layout, the pixels of the background image looks like blurry. I think there must be a resolution problem. For example in api demos there is a module in this path graphics/bitmapspixels. My background image is looks like a third image. I would need to show my background image like the second one. How to do this?

Unable To Access Pixels Of A Bitmap Image On Droid / Solution For It

In short i am unable to access all the pixels of a bitmap image.

I have used an intent to fire the native camera app and returned a bitmap image to my application activity. The data is definitely a bitmap object and i am able to display, get the height/width etc and access some pixels using getpixel(). However when i use the values of getheight() and getwidth() i get an array out of bounds error. By trail and error i have found i can only access a reduced number of pixels of the image, for example with one image which returned a height and width value of 420, 380, i could also access 200, 100. I then do some image processing and used setpixel() on the original image. When i display the image it shows the, say 200, 100, processing pixels and the rest normal, therefore the pixels are obviously there and accessible by android but not by me. I have to spoken to other people who have also had this problem with images.

Does anyone know anything more about this, reasons? Or a work around?

Real Poly / Sec On Adp1

Well i've been searching for this information for a while and can't find any resent real world numbers, the qualcomm® msm7200a, , 528 mhz is said to be able to produce 4 mpolys/sec but the only information i can find for real "phone" performance is more like 100 kpolys/sec which is just 2, 5% of the stated possible performance. (These numbers are old, mid 2008 from what i can find) while i understand the jni calls limit the speed a bit but can it really be that much? Quick math then says

Then on that you need to remove some since you probably want some other stuff running as well so lest say half that a frame to keep a steady 20fps+ and with the overhead of jni also included, if the phone then can't push out more than 100 kpolys/sec you end up with maybe a 1000-2000 polys for each scene which is really limiting for a game compared to maybe 60-80k polys. Is there any real test numbers out there for the adp1 as to what it really can push out and if so how big difference is the java opengl es calls via jni compared to native code for opengl es hooked from a java?

Facebook App To Notify Me In Real Time

Which facebook apps will give me a popup/message regarding any facebook updates relevant to me in real time? The 'facebook' app that i have right now only updates itself every 30 minutes, so any pop-ups that i recieve are potentially 30minutes old. This isn't much good for me as i get quite a lot of wall posts some days from friends relating to going out, work issues etc. It seems to have replaced sms for some people!

Are there any apps that will keep me updated 'live'?

Also, what is the best app for facebook chat? I tried ebuddy yesterday, but it caused a login error and on my netbook i was prompted with a security screen because my account had been accessed by an ip in america (the ebuddy servers). The ip is different each time so it seems like this won't be a suitable app for me.

In an ideal world, i'd like an app that was a compressed version of the full facebook site. Buttons for each popular function, a chat facility and updates that happen as-they-happen.

Live Wallpaper Preview / Real Conflict

I've made a lwp, and it seemingly runs perfectly, but the problem seems to lie in the fact that when you set the wallpaper, after the preview has loaded, it gets a out-of-memory. It seems that since all the engines are in the same vm i don't have enough memory to start it a second time. How can i tell if the preview is dead and freed? I've done what i could to ensure that as much is shared between the engines as possible, yet still out-of-memory on setting after the preview is loaded?

Handle A Pound Sign (#) In A String

I built a music player in my app and just discovered a little quark while trying to play "#1 crush" by garbage. When i send the songs path to the mediaplayer, everything from the # sign on gets dropped off. I tried inserting a "" in front of it, but that causes everything *after* the pound sign to get dropped. And i'm having trouble inserting "" in there.

I know this is a simple fix, but, friday afternoon, i can't think of it.

Set Max Width Of Horizontal Linearlayout

How can i set max width of horizontal linearlayout? So if the contents is short (say, some text), the layout shrinks and if the contents is longer - it will not expand more than some max width value.

I prefer doing it at the xml level.

Pls let me know if my question is not clear enough.
