Android :: Object Relational Mapping - Tiny ORM On GitWeb
Jul 17, 2010
Is this project Tiny ORM written by Shawn O. Pearce going to be equivalent to Hibernate in Java ActiveRecord in Ruby Doctrine in PHP http:// android. git.kernel.org/?p=tools/gwtorm.git;a=summary Does any one know if Google is working on an ORM for Android. What are the similarities and differences between Tiny ORM and the above named projects? Why are protocol buffers being used in the ORM, I do not understand the relationship between protocol buffers and ORM concepts. I found the above link by reading this blog post.http://mobilebytes. wordpress.com /2009 /06/14/ android-orm-coming/ I have been hearing rumblings about this, but was just curious if anyone has any further information.

I have several related database tables and I would like to treat their rows as objects and their tables as something like lists. What are the considerations that I have to keep in mind (for instance, ensuring that the objects stay consistent with one another and with the database, lazy loading)? And what is a good design pattern for implementing this? As I imaging the answer is pretty involved, a link to a good website would suffice.
On the other hand, if someone knows of Hibernate-like thing that really works on Android, I might give that a whirl (although it's a little heavy weight for me right now).

I want to do some automated testcase with Instrumentation . Suggest that my AUT has 2 Activity. After clicking the button in ther first Activity, the second one will be shown with new content base on what we enter in the first Activity.) Instrumentation provides us the function called startActivitySync() and return the Activity object for processing. My question is how we can get the pointer of the second Activity after the it is shown by clicking the button on the first activity.?

I have an Activity that running on system. I can get the Intent that is used to start the activity. But i don't know how to get the Activity object from the Intent object or something else. Can anyone tell me how to do this??? Note that, I don't use Instrumentation object.

When I go into my Internet and click on a webpage the view is really tiny. I had this issue once before and can't remember how to fix it.

I took a photo in San Francisco yesterday with Droid and uploaded it using Facebook app. But it is really tiny, downsized too much.Overall, it's a great phone. Do wish it had some Sense UI sexiness though!

I am asking about the development of an Android application that must work in backgroup (so no user interface).
Usually my application extend to the activity class that manage all the application process.
Maybe i can avoid any setContentView() that won't display anything but i don't want any icon .

Let's share info on how we who have poor eyesight can better use our Android phones, what do you say?
1. A program called Spare Parts would allow you to increase font size for many apps. Does not work for the HTC Hero (OS 1.5). Unknown if it woks for any other OS or phone that is currently in existence.
2. A program called Bettercut allows you to create a Display shortcut and use that to enlarge text on some apps. Does not work on the HTC Hero (1.5). Developer says it may be because of the special Home screen the Hero has. Unknown if it works for any other OS or phone.
3. Browser allows you to zoom in out of the box (unless you searched google!)
4. Do OS versions 1.6 and 2.0 allow one to enlarge text out of the box?

there im looking at gettin g a new phone, and this is really the deciding figure between a blackberry, iphone or android device. What im looking for is a gps app sorta like gpsed that can map my tracks and put photos on them, but that stores these maps on my phone not the internet. Also what i would like is to ba able to take a picture with my phone and quickly be able to attatch it to my map. So when i go to this map in zoomed out mode i can see all these tracks (possibly in different colors) and these pins which i can click on and see pics of that location.

A user of my Android App reported that he was seeing tiny text. How is this possible? More importantly, how can I use the emulator to be sure that my changes will fix it?This user has a Motorola DROID phone, which has a different screen resolution and maybe other slight differences.I assume that the problem was I didn't test using the right screen size. However, I followed the instructions here and tested a larger screen and the text was fine. I know my app has fixed pixel heights like this: android:layout_height="64px" and I use text side parameters like: android:textSize="14sp" or android:textSize="12pt"

I'm very happy with my new smartphone, the Galaxy S from Samsung . I don't use any protection for the screen, so i wipe out the "fingerprints" with something to make it nice and shiny! However i did use, several times, paper tissues. Big mistake. If i hold down the phone in bright light, i see tiny scratches on the surface .
So only use cloth and nothing less if you don't use protection, but NEVER use paper tissues!

I'm trying to get the lat/long values, from the corners of the screen. But my getProjections don't make any sense.. I mean ... mymap.getProjection().fromPixels(0, 0) or mymap.getProjection().fromPixels(screenWidth, screenHeight) just delivers me unreal numbers..
I'm trying to set up an algorythm that would avoid cluster of graphics in the map and for that, the app needs to know which area of the screen is being showed latitude/longitude wise.
For example:

Is it possible at this time to get normal mapping to work on android? I'm asking because it would involve the use of GL_DOT3_RGB, which is in the GL11 specs, not GL10. But GL11 is indicated as not completely supported.Is there an official list of GL11 features that do not work, or is it simply unstable and I should just avoid it for now?

I have a love-hate relationship with my G1, with the inability to remap keys at the top of the list. I've looked high and low for information, going so far as to try to decipher pages like this:http://www.kandroid.org /android_pdk/keymaps_keyboard_input.html and even reading the android platform code on github. I don't see things like page_up and page_down defined in the android keymappings. And I suspect that the original scancodes are being assigned to touch gestures.Since the number keys don't have a third component could an enterprising developer map to the unused caps for missing keys? Not that it would be all that useful at this point but it would give someone a hook to build on. Or if that isn't possible, how about a virtual floating task bar kind of thing (maybe mostly transparent overlay?) that maps gestures like the swipe up/swipe down and more traditional arrows and enter type keys for the trackball? This isn't entirely a nit-picky kind of request. I have a medical condition that in the winter makes my fingertips extremely painful and the trackball hurts. I'm guessing that there weren't many arthritis sufferers on the Android development team, either. You would think that the touch screen should make things easier, not harder. Even my old, old Omnigo and HP100LX had utilities to remap keys, so it seems odd that there isn't some kind of app that could be developed. I think if I had enough time (which I don't) I might be able to eventually puzzle out a crude version of the task bar thing but I'd much rather pay a couple of dollars in the market.

I've tried casting shadow following this tutorial (which uses Stencil Buffer method): http://nehe.gamedev.net/data/lessons/lesson.asp?lesson=27 The result is a cool shadow effect. But it depends too much on geometry and thus not very flexible. Then I found a much easier way to do shadowing here: http://www.paulsprojects.net/tutorials/smt/smt.html But it uses ARB_depth_texture and ARB_shadow extension. So I bet it can't be used with Android's OpenGL ES 1.0. I've tried googling for "Shadow Mapping" and "OpenGL ES" but still can't find a good tutorial. Can anyone recommend me a good place/site I can study for this please?

Ok so here's the deal guys and gals, I am trying to have my phone assist me with my running. There are plenty of apps that will track my run via gps if I bring my phone on the run with me, but I don't wanna do that. I want to be able to map a course out, enter how long it took me, save the map and even share it with friends. Ideally the app would have the gps running features I mentioned above just on case I ever do start bringing my phone with me. Here is an example of what I mean in website form (unfortunately they make a sweet app for the iphone but their android version is pretty awful right now.MapMyRun.com -

I am looking for an application that can create a map by me carrying the phone and walking a certain path.There is a 300 acre park near where I live. The maps they provide are way off base. I would like to walk all of the trails and have the Droid record where I am walking.You know, this may be easier than I think using ASE and writing a Python script. I'll just get the location every half second and write it out to a file. It'll be interesting to see how the maps turn out, seeing the low resolution of the GPS receiver.

I am trying to get a FileInputStream object on an image that the user selects from the picture gallery.
This is the android URI returned by android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI content://media/external/images/media/3
When I try to construct a java URI object from this object, I get an IllegalArgumentException with the exception description Expected file scheme in URI: content://media/external/images/media/3 whereas the android URI shows the scheme as content
Never found a solution for the original question. But if you want the byte stream of an image in the pictures gallery, this piece of code will do that.

I am writing an Android AR application and have my engine working but it contains a strange behaviour that I can't seem to get fix. I am overlaying an OpenGL surface on the camera image and am placing 3D objects in the view accordingly. If I use dummy data for the location of my AR objects, i.e. LAT 10 LON 10 become x=10 y=10 on the OpenGL surface, then the overlay works perfectly. However, if I use direct GPS coordinates for my LAT and LON (e.g. LAT 12.34567890 LON 100.23456789) then all my objects either move around their location or don't appear at all. I know there are issues around using floating points and the OpenGL framework, but I've been reading around and am still having trouble stopping this behaviour. Has anyone else had this problem? Should I be using a scaling factor between my GPS and openGL surface, if so what values are good? I tried scaling my LAT and LON by 1000000 to eliminate the floating point, but it didn't help and the performance was terrible.

Currently I'm using a HashMap to map the strings to int and the int values need to be frequently accessed. I'm looking for a better way to do this if possible with minimal object creation, and preferable being able to store the values as primitive ints without wrapping them with the Integer class. (Basically, the reverse of the SparseArray's int->object mapping.)

i have a list view and custom list adapter for it. There are various other fields in it and a Checkbox. The problem is that it is not able to map Checkboxes properly. I mean if an entry is already present in database it should come checked.When i put a log in the View function it shows some of the entries that are repeated, i think this is the main reason.

I was going through the code of API demos.I understood how to map a single image resource on to all the 6 faces of the cube,but i want to know how can i map 6 faces of the cube with 6 different images. I searched in the web without any luck.Can any one give me some ideas links , pointers on the same.

I have an Android application that displays VGA (640x480) frames using OpenGL ES. The application reads each frame from a movie file and updates the texture accordingly. My problem is that, it is taking almost 30 ms. to draw each frame using OpenGL. Similar test using the Canvas/drawBitmap was around 6 ms on the same device. I'm following the same OpenGL calls that VLC Media Player is using, so I'm assuming that those are optimized for this purpose.

How do I run the emulator with WVGA854 skin so I get a 1-1 mapping of device to screen pixels? The WVGA854/layout file has "width 480 height 854" but when I run the emulator, I get these values for DeviceMetrics: density = 1.5 densityDpi = 240 scaledDensity = 1.5 heightPixels = 569 widthPixels = 320 xdpi = 240.0 ydpi = 240.0 I'd like to run the emulator so that I see heightPixels/widthPixels values of 854/480 in the code. I tried playing with the -dpi-device option but doesn't seem to help.

Ever since my OTA upgrade, every time I use the internet, everything is extremely tiny. I think its not the mobile internet but instead the full version. Now I have to zoom way in to view anything and its a real nuisance. Anyone else having this issue?

The speaker is on the back of the phone, below the battery cover. When I hold the phone by its sides while watching a video, the speaker sound can sound tiny. But when I cup the back of the phone with my right hand, the volume is increased, possibly because the sound bounces off my hand.
