I want to create a simple android binary clock but my application crashes. I use 6 textview fields: 3 for the decimal and 3 for the binary representation of the current time (HH:mm:ss).
Here's the code:

Is there a fix or will I just have to go cook steaks while the emulator is booting?
View 3 Replies View RelatedI have yet to try this on an actual device, but expect similar results. Anyway, long story short, whenever I run my app on the emulator, it crashes due to an out of memory exception.
My code really is essentially the same as the camera preview API demo from google, which runs perfectly fine.
The only file in the app (that I created/use) is as below-

Im looking for a digital clock widget that is just the clock. No weather or anything like that. Sounds simple enough? Well, the problem is, I find all these nice clocks but theyre all 1x2 or even 1x1. Im looking for something atleast 1x4. 2x4 is fine also. I like beautiful widgets but I dont want the weather.

A text editor that can create/edit text files from the SD card.
i.e. Windows Notepad on the Desire?
I think I already know the answer to these, but I'm going to ask anway:
1) Is there a straightforward way to set the background color of a tab in its unselected state?
2) Is there a simple way to align the text on a tab?

I want to do very simple android program,
Refer some good tutorial.
So I started with this little write-up. I wanted to try to make an application that will take pictures while running in the background. To start though I wanted an application that once opened would simply take a picture every X seconds. After recreating the classes and methods show in the walk through below I ran into a few problems.
http://itp.nyu.edu/~sve204/mobilemedia_spring10/androidCamera101.pdf
For starters its seems that the onCreate function sets up all the objects for the application, but if you try to take a picture through any other method than onClick (IE directly calling it) the application actually hasn't setup the canvas or the preview yet.
My first question:
Is there any conditional method that you can setup that will wait till all the "onCreate" objects are created and their associated methods are called and finished? How do I wait for the application to finish putting together my surface and starting the cameras preview before automatically starting to take pictures?
My second question:
I am required to have a preview available to take pictures. Is there anyway to push this application to the back (IE running in the background) while still taking pictures? Is drawing to a canvas a requirement? (From what I can tell AFAIK, you are required to have a surfaceholder to start preview, when you put up another screen or application that pauses the current application and closes the surface/canvas you were presenting that preview on). If my understanding is correct on all of this the best I will be able to do is make a 1x1 pixel canvas that will still take up the screen due to the application being in the foreground.
My Third question:
Is there any way around this? Can you still utilize the camera in some fashion without requiring the preview be drawn?
My app is using the camera on the phone. For phones w/ 2.0+ I have been able to activate the Flash. When I test on a phone with 1.5 OS on it the app crashes. I get: java.lang.reflect.InvocationTargetException and the Cause is java.lang.VerifyError: fishers.Nav.TakePicture$1
I assume because you have to access the flash differently in apps below 2.0? Can anyone give me some advice or links to examples showing how I could make it work over the whole range of Operating System version or is that just not at all do-able?
I have a small mp3 (326KB) in my res/raw folder. In my code, I have mPlayer = MediaPlayer.create(FakeCallScreen.this, R.raw.sample); Player.prepare(); mPlayer.start(); The application just crashes when it tries to start the activity, I cannot figure out why.

I am new to Android.. and smartphones for that matter. I am looking for a very simple app that has bill reminders. I do not really want it to have access to the network, therefore using data constantly.
I guess I just want to be able to put in my bills and have them show up on a screen so I can see what is due, and paid. A pop up reminder would be okay.
I downloaded Astrid, but it looks like that one uses network access constantly. I prefer this to not be the case. Does an app of this sort that does not access the network whenever it wants even exist?
My Android Desire is a superb device and will do almost anything I want. Even cleans up around the house and makes coffee and feeds the cat. However, there is one simple thing I cannot get it to do: provide me with a simple text editor like Wordpad so that I can write little texts on the go. I've searched everywhere for this function. I cannot imagine that it is missing from the phone, it's so basic. When I search for "text" I get all sorts of stuff on writing "text" messages, i.e. SMS messages (the term "text" seems to have lost its original meaning and is now used almost exclusively to refer to SMS messages). Where is the Desire equivalent of Wordpad or Notepad or, better, Notepad++?

View 1 Replies View RelatedI'm nearly ready to publish my OpenGL game. I've been browsing this newsgroup and I've seen quite a few posts regarding crashes, blank screens, etc when running an OpenGL application on the Droid. I have three questions:
1) What are some common pitfalls that occur when trying to support the Droid/Nexus One? So far, I've tested my game on the Android 2.0 emulator (both WVGA & FWVGA) and everything works fine but I'm still paranoid.
2) I've placed my textures (png) in the assets folder. Will these images be pre-scaled automatically? I've read about specifying density independent images for resources but do the same rules apply for images stored in the assets folder? I'm afraid that pre-scaling will cause my textures to become non-power of 2.
3) What additional strategies have developers been taking to ensure their application works on the newer devices when they only have access to G1/G2 hardware?
