Android :: Implement A Paint-update Loop ?
Sep 8, 2010
I want to create a paint and update loop in android for game animation on a canvas but I am having trouble as I can't seem to get the threading to work appropriately. It seems to crash almost immediately.
Here is what I have tried:
CODE:................
Also when I drop the wait down lower it crashes faster. Is there a more appropriate way to approach this?
Changed to this:
CODE:........
This results in the same error...

I rooted my managers phone and gave her 0.5.3 back when it was the standard fresh rom. Well last night she used fresh updater I believe to go to 3.1.0.2, which I know requires a wipe but she isn't exactly savvy on all of this. In any event, after the update the phone does not load the launcher. Upon unlocking the phone it is stuck in the com.htc.launcher has stopped unexpectedly. And after force close it loops this error. I can only see the lock screen or access the phone's SD card from my PC, I can change options such as "charge only" "disk drive" "usb debugging" but that's about it. Other than that I can get to Amon Ra recovery.What are my options for helping her out with this?

I updated to BB 0.4 from a previous old 2.2 installation. Now I'm stuck in an endless reboot loop! It alternates between Droid and the red Droid eye!
1) I copied update.zip to the root of the drive.
2) I installed update.zip
3) Install was successful
4) Rebooted

, i followed the directions for updating the droid to 2.1. Now stuck in a boot loop. The firmware updated fine and didn't indicate a failure, after i updated i did the reboot from the menu. I've reflashed 2-3 times now and it does not come back, and i've pulled the battery more than a few times.

Since the update my Eris has been in a constant loop of trying to power on. It only ever gets to the silver htc on the black screen then it goes completely black and then goes back to the red smear for verison and the little droids then over again. I've already taken out the battery and tried again but no help.

I did the offical Froyo update on my phone this afternoon. It was stock with the latest OTA update 1.47. Followed the directions for the update and it went by smoothly until after I tried setting up my phone (Google account). I did a hard reset and everything was fine until a few minutes ago. I was able to sign into my Google, Facebook and Aim accounts. It is now back to an endless loop of trying to load Sense and force closing. Of course I can do another hard rest but is it too early to assume the force close loop problem will return? My phone is not functioning and I cannot even go into the setting to turn of Sense.

I had my Galaxy Pocket rooted and got the Jellyblast v3 rom, it was doin fine until I checked on the app OTA and check for update, a new update appeared which is the Nemesis 2.5 Hybrid-Holo Editon. It asked me to download it and so I did. When it was done, it asked me if I wanted to install it and so I did, and rebooted. Later I noticed that it was already boot looping. I tried pulling the battery off and to clockwork mode, with the proper procedure..the holds and presses, but still it just kept boot looping. Tried to connect it to the PC using the USB chord and yet it just shows the charging icon and sooner it turns to white. I tried Kies but still it turned white screen all over again; no device found.

Just did the OTA froyo update from O2 last night. All appeared to go well and successful, past the point where I heard other people's got stuck.But when I slide down the slider and put in my password, it gets stuck in a force close loop for com.htc.launcher. Seems to not be able to open sense and keeps looping round.I saw a post from someone saying they had that problem, but then they just hit the search button and got the quicksearch, went to settings, then cleared the data for the appropriate application and then it worked fine.But when I hit the search button, nothing happens. If I hold it down, I get the google voice search, but I can't seem to get to settings from there.Does anyone know another method to get into settings as I'm hopeful this will fix my problem as suggested by some others. I'd much rather that than take it back to O2.

I tried to force ics update to my phone and it is stuck on the big Motorola M screen. ive tried to flash the update just like you would a rom and it didn't work. it was my only option cause the guide i was following was for a pc and I own a mac so the utility provided wouldn't open on my computer. after it didn't work i tried a factory reset but that hasn't done anything. what can i do? the sd card wont mount on my comp so i cant put anything on that.

So I was having a problem with my Optimus V (Virginmobile) and I couldn't send or receive texts. I did a factory restart thinking it would work but then found myself at the recovery menu. When I try to flash xionia_cwma_12518.6.zip it says E:cant find update script. When I try and flash CM7.2RC1_VM670-BobZhome-052012 it installs and when I reboot i get taken back to the recovery menu.
In short; My Virgin Mobile Optimus V is stuck in a recovery loop that I am unable to get out of due to an error while trying to flash ROMs/ Custom Recovery.
The error reads at the end of all attempts: E: Can't find update script.

I'd like to include a simple draw feature on my app. A friend told me I can't use canvas because I need to control the frame buffer and not redraw the entire screen every for every frame.He suggested I find a openGL 2d engine.I've searched around and I've only found Rokon which doesn't have any documentation and the examples aren't quite what I need.Any suggestions?

I'm new to Android and Java programming and I've manage to create a simple paint program, but how do I add a zoom feature? Right now I'm just extending the View class and using the "on Draw()" method. Do I have to use a Drawable to be able to add zooming functionality? I'm not really understanding the differences between the two. If I am way off base then please point me to a good tutorial on paint/zooming.

My app uses a custom View that does a lot of text drawing.To ensure my text is always readable I've been using the result of calling getTextSize() on a newly-created Paint() instance as the minimum size. Docs say calling 'new Paint()' sets attributes like text size to default values.One of my European users just got a Motorola Milestone phone and reports that some text is unreadably small.I believe I've duplicated this using the WVGA854 skin in a 2.1 emulator.Run in that emulator my app's smallest TextViews look fine, but the text I'm drawing myself using Paint instances where I haven't changed the text size from the default is too small. I confirmed this by commenting out all setTextSize() calls in my View subclass: the text becomes too small to read comfortably.

I'm looking for an application that will allow one to open an image (or pdf, preferably) of a worksheet and allow one to "do" that worksheet; in other words draw/write on the image/pdf.

To explain i have a bitmap which is constructed as follows
Paint a rectangle color yellow I want now to paint a smaller circle over the top of the rectangle, but i want to use transparency. so that the circle results as a hole in the rectangle. {like swiss cheese with holes }
So if i painted the bitmap over a background the background would still be visible in the Circle/hole.
setting the drawcolor drawColor(Color.TRANSPARENT) just paints a transparent object. i.e. it doesn't erase the circle area of the rectangle.
How to do...?
One option is to set the circle color to say black and then look for an option to replace black with transparent within the bitmap.... but i can't find a solution for this either.

I'm trying to develop an RPG for Android, so I need to paint a scenario where I'll move my character.
My idea is to do it 2D. I've developed 3D games and Java games for desktop, but in Android i don't get how to star the scenario.
Could it be developed with a matrix of information, so I could know where my character steps?

I'm designing a custom view which is an X/Y Plot. It's a moving graph that scrolls to the left with time and new Y values are continuously coming in at 10 per second.
I've been able to make it work with an array of integers where the array index is the X value and the integer value is the Y value, but this seems horribly inefficient (Because every time it comes time to re-paint, I have to loop 800+ times to paint the graph). Then we do it all again 10 times a second. yuck.
Can anybody think of a paintable object that I can draw points to and perform some kind of scroll transformation and then just draw the new points each time, rather than the whole canvas?
Any other ideas out there?

The issue I am experiencing is that the SurfaceView I am using flickers. Once in a while, the objects I draw flicker and they change their size or colour.
It looks like that sometimes the application skips my calls to 'Paint.setColor()' and the one to 'Paint.setStrokeWidth()'.
I have made methods which change the used paint and then, in order to try to fix this issue, to set it back to the default paint values. Still the issue persists. I have also read that the problem might be due to the double buffering. Is it the case? I am using this code for the DrawingThread:
I also tried to use a dirty Rectangle to try to see if the issue can be fixed, but still nothing. [I might not have understood what it actually does.
Code:
class DrawingThread extends Thread {
private SurfaceHolder _surfaceHolder;
private CustomView _cv;
private boolean _run = false;
[Code] .....
I have read somewhere I should draw on a single bitmap and then draw the bitmap on the canvas. I have tried several times but I cannot manage to do so.

I'm developing a coloring book app, how do I ensure that the black outlines of my drawing are not colored by the paint brush? I thought of decreasing the alpha value of the paint brush to show the black outlines when painting over them but upon painting the same area again, the black outlines will be painted over.

I'm using the FontFitTextView that was posted in this other thread, but it isn't working exactly right for me. The measureText() call is returning a number that is obviously too small to display the string. When it runs through to find a font size that will allow the text to fit, the font size it settles on is still too big. I feel like there is some other kind of padding or margin or some other invisible that is contributing the math that makes up the width which is causing the discrepancy.For example I want to set the text of my FontFitTextView to be "10,000.25".The width of my FontFitTextView is 96 pixels, with 8px padding on both sides, so my available width is 80 pixels. The call to measureText() says that the text "10,000.25" is 64 pixels wide. This means that the current font size should be small enough to display the entire string. However, when the string is actually drawn on the TextView the last 2 characters are chopped off and all I see is "10,000." instead of "10,000.25"

I've had the phone only since Tuesday, and I just noticed a dent in the paint, if that's the correct description, near the bottom right corner (an inch below the Search button, slightly to the right). It looks as if someone pushed their finger nail into the paint really hard. It's the same height as the letter G in "SAMSUNG" printed under the screen.
The phone was dropped by a child on the car mat once before, but I don't think that's what caused it.Any ideas on how to fix it, or if I can get it replaced? (I got it from letstalk.com for free with contract).

There seams to be a widespread problem of the gold coated camera button flaking and or wearing over time. The top of my camera button is completely white and looks awful.Other then this,I have no complaints about the phone.Don't feel like dealing with VZ or Moto and getting a new phone for something so small.Has anyone painted the camera button?If so what kind did you use and how does it look?
