[android-developers] Re: Sharing SQLite Database between activities
Probably the model that your looking for is a local service. Keep all your interaction with the db in the one service. Open the db in onCreate and close it in onDestroy. You can bind to it from multple Activities - and if your service is still there when binding so is your db without replicating code all over the place. Have a look at http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/app/index.html Just one word of caution. Dont use a Binder as a non-static inner class or you may leak the service. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: got a problem to learn Android
The best Java tutorials are the Sun The Java Tutorials on the internet. Since Android uses the Java programming language but uses a different virtual machine, you can overlook some of the JVM-related comments in the tutorials but programming is the same in every language, so what you learn in Java, you can translate over to any other language, and develop in that also.

[android-developers] Re: How to capture game screens on device
3 - I haven't convinced Android x86 running in a VM to run at Android standard resolution yet. It should be easy to capture video from it similarly if I ever do. Out of curiosity, what problems did you encounter with this? So far I've just run Android x86 on VirtualBox, intending to capture video via the host should I get to that point. It's using desktop resolutions by default, however, so a portrait only activity will still get given a screen that is wider than it is tall and look screwed up, for example. None of the options in the vga=ask boot option seem like they can fix this alone, although maybe if I could figure out how to change the orientation as well, or tried a different VM with a different virtual video adapter. I haven't gotten the UVESA_MODE boot option to work. Guess I could change the apps I want to record to better handle the bizarre resolutions. 5 - Some Android phones can supposedly output apps to TV output, which could also do the job combined with a capture device. I'm not aware of any that output the standard Android screen to HDMI. For example, the EVO's HDMI output is for video playback and the Gallery app only. If anyone knows of one that shows the actual Android screen on HDMI, speak up! Yeah, I read in a review that the Evo 4G is useless for this. I was thinking of the Droid Incredible with TV out accessory when I wrote that. I saw a video of it outputting the home screen at least, so there's a chance it can do apps as well. Not sure if it outputs HDMI or something else. Are you interested for the purposes of showing Android full screen on a projector during talks and classes? My favorite thing for that so far is to just run the emulator skinless, with the -skin 320x480 command line option, for example, and then set it to full screen mode using the key combination for that. Looks better than a document camera, for non-OpenGL stuff anyway, in my opinion. I tried installing a custom mouse pointer that looks like a huge finger, so people can better tell where I'm clicking, but the emulator seems to override it as soon as my mouse moves over it. So that's a drawback, I guess. I have to use Android 1.5 with that method, unfortunately, because it gets better frame rate on the emulator than 2.2 even, but it crashes all over the place outside my apps, like when playing with the wireless/airplane mode in the settings app. I assume you could use a modern, bloated Android version, though.

[android-developers] Re: Moto Droid ADB Drivers no longer work after HTC Evo was used.
Weird that it matters what previous versions are laying around. On my Windows 7 (32-bit) machine, at least, I can flat out force it to use the latest. So old versions don't matter. Goes something like: make sure latest SDK USB drivers are downloaded to the default Android windows SDK usb_driver directory, press windows + pause/break to go to system properties, choose device manager, right- click on malfunctioning ADB device, choose update driver software, choose browse my computer, browse to the Android windows SDK usb_driver directory, press next, see installing your device software screen, see driver software successfully installed screen. No clue how it goes on 2k3. I've always assumed that when it says installing it is copying the files over to system32/drivers, so I don't think any old locations matter anyway. You might see them listed in some update driver dialogs simply as a shortcut to reuse a previously used location.

However, that hasn't stopped me from deleting them and download them several additional times through the SDK. I have also gone as far as to download random other SDK versions I found floating about the internet. I still can't find the one single place that tells it to keep looking at the SDK for the drivers. Somewhere in some registry setting or file it's telling it hey go look in this usb_driver folder for files. I've deleted a billion things out of my registry but so far no success.

I'm using Usb Driver package, revision 3 according to the Android SDK and AVD Manager. You can update it from the same in the available packages section if yours is earlier.

I did eventually get both phones working at once. Basically I just tried lots of combinations of removing everything HTC/Motorola in remove programs, reinstalling them, connecting and disconnecting devices, and the star of the show: right clicking on devices in the device manager and choosing to update their drivers and picking a different one from the list of applicable drivers. You can use this, for example, to change a Mot Composite ADB Interface to an Android Composite ADB Interface by choosing the Android drivers instead of Motorola's. My currently working setup doesn't even have Motorola's software installed, but does have HTC's. There are several Android Composite ADB Interface for theDroidand other phones, and one My HTC, no Mot Composite ADB Interface. Kind of sad HTC screwed everything up, but I had to uninstall Motorola, but whatever. Although if you have something pointing to a removed directory somehow I'd try fixing that first via similar right-clicking on devices and updating methods.

(then switch the array pointers back so the 3D stuff works again). I get nothing added to the screen (just the 3D stuff). Do I need to be doing something else for it to draw?

Re: [android-developers] Re: Is runtime mapview defining possible? (rather then in main.xml)
I think I worked it out. I had imported the maps.jar file into my build path, rather then just setting the target to GoogleAPI 7 under the android tab. (with that set, I could remove the manually imported maps.jar file and it worked fine). I was overcomplicating maters :) Cheers, Thomas On 27 June 2010 17:16, HeHe cnm...@gmail.com wrote: sorry it does not work for you. it is odd. all map views of my app are dynamically created and inserted this way. i need to check if they are ok with debug and release modes while i dont want to hardcode map key in layout xml and manually modify xml whenever i switch my app between two modes. anyway hope you find a way out soon.

Even developers sometimes miss that certain apps have menus: we've had questions in this group about clearing Market app reviews, and skipping entries in the ADC2 app, for instance.

[android-developers] Re: Mapping Multiple textures to a cube in Android OpenGL ES
Thanks Robert, So in short you are stating that I use a texture atlas approach. The second approach is what I used right now, for every face of the cube construct that side and binding it to the texture which was really inefficient. Well, you have said something about the distortion. I read at nehe's site that you can use mimaps to upload image of any size which will be scaled to the best aspect ratio and will minimize the distortion. Could I use that technique to create the texture atlas? Also, could you give me some pointers or articles which discuss the creation of a texture atlas since I'm fairly new at this. On Jun 26, 12:01 am, Robert Green rbgrn@gmail.com wrote: No, that's not what cube maps are for. You can only draw 1 texture at a time (unless multitexturing but that's totally different and not what you want) so you have 2 options: 1) Combine all textures together into a single one and map the coordinates to each side accordingly (will run much faster) 2) Draw side-at-a-time binding to the appropriate texture for each side. (not usually the preferred method.) A trick many of us use when doing something like... say you want to have the user pick 6 photos from their SD card and then you want to display those on a cube, one on each face. At some point you must load each photo up, clipping and scaling it to fit aspect ratio and a power-of-two texture and then uploading it to vram. Well, instead of uploading each one as a separate texture, why not just create a 1024x1024 bitmap and draw all 6 photos to it in different spots. You could use 50% of the texture vertically and 33% horizontally (for example) to pack 6 photos onto it for 100% usage. It's ok if they distort going on to it so long as you draw them aspect-correct. You then keep track of which one is where (using UVs, so percentages from 0 to 1). Upload that texture atlas as a single texture and when you draw your cube, you just bind to that atlas once and draw everything in one shot. It'll run fast and it's not really that hard to do.

I even mapped multiple textures to different faces of the cube. But the way I did it was to create 6 faces seperately, have 6 seperate index and texture buffers and then using glBindTexture() with the selected texture for each face and then calling glDrawElements. Isn't there an efficient way around this. Should i use a cube map texture instead of a GL_TEXTURE_2D? Any suggestions would be appreciated?

[android-developers] Designing and Implementing Android App Idea
Does anyone have any good references for designing and implementing an idea I have for an android application. My idea is for an application that stores information and reviews about a specific location and presents this information to user.

You might want to review the other apps that have a similar theme, check out http://www.androlib.com or http://cyrket.com for a web based app search tool, then try them on your Android device to see if your idea is anything unique. After that, I suggest looking at this site: http://commonsware.com/ - Mark has some great books and tutorials on Android.

[android-developers] Re: Do VBOs really improve performance? Really?
Do VBOs do anything on a device with unified memory? There is no separate graphics memory on many of these devices, right?

If you're not seeing any performance differences, it would be helpful if you listed on which device, what your FPS is with/without VBOs, etc.. It sounds like you're doing it right. I doubt it matters how you partition the vertex attributes. You can do what you do or do what I do which is have 3 separate VBOs for them. I would expect no difference there. If you're not getting a performance improvement then that's not a bottleneck for your app/game, but it's still lightening the load on the bus so is a good thing overall.

I can answer the question are VBOs faster for large amounts of static geometry and the answer in my experience has been yes, very much so, especially on first-gen devices. For quads and such? No. In fact, it could actually be slower depending on the chip and implementation. VBOs are designed to reduce bus bandwidth usage for static geometry. If you're not pushing too much across that bus (as in the case of quads or very few, very low poly objects), they won't do much. If, on the other hand, you're actually running static scenes that are moving 5k polys per draw eg (7.5k verts, 7.5k normals, 15k indices, 7.5k UVs) = 270Kb, you will most likely see some sort of improvement, especially on chips like the qualcomms as they have fairly slow transfers. Just think, 270Kb @30fps = 8.1Mb of memory copying per second you're saving using VBOs. If you're rendering scenes that have REALLY large amounts of geometry (for mobile), such as 50k or 100k polys, you'll find that you'll be totally vert-bound on the first gen devices, so there's kind of that limit there as to how effective VBOs can be. The spots where they REALLY shine, like really high poly counts, can't ever be used on the first-gen phones because they are incapable of processing that many vertices with high efficiency anyway. High end devices running big scenes like that will really benefit from them because it's a whole lot of memory transfer savings. Anyone doing things like that will want to be using configurable LoD to support the first-gens while keeping things high quality on newer chips. I would be interested in a simple test that increases poly count frame by frame and graphs the FPS up from 0 to 100k polys. Running one pass textured and the other just colored would be a good way to discriminate between becoming fill-bound and memory or vert-bound.

I think it's working now. Though I don't know why my map center

On Jun 27, 2010, at 2:37 AM, Brad Gies wrote:
I hope it's generic for all zoom levels.. it should be :).
How it works is that Google Maps at a zoom level of 1 displays the
entire world in 256 pixels... When you go to zoom level 2 you get
half the world in 256 pixels, zoom level 3 is 1/4 the world in 256
pixels... which is the same as 1 divided by 2 (to the power of
zoom level - 1), so the Math.pow(2, zoomLevel - 1) just gets the
number that corresponds to what you need to adjust by for the zoom
level.
All these functions could be (and will be) combined into about 3
lines for production.. but I just needed to step through it one step
at a time to test it out.
The double entireWorld = zoomToPower * 256; just calculates how
many pixels it would take to show the entire world (height or width)
and then I just brought it down to 1 degree so I could check the
calculations against a map and see what I was doing :).
double OneDegree = entireWorld / 360;
This calculates how much of a degree your screen will show for both
the height and width of your screen. I subtracted 40 pixels from the
height because that's roughly what my activity uses... and I didn't
care if I was exact.. I only want very close. I use it to call a web
service and I pass the Map Center latitude and longitude to the web
service along with the screen size (in degrees),
double heightSpan = (display.getHeight() - 40) / OneDegree;
double widthSpan = display.getWidth() / OneDegree;
and this is how I used it. Because my function returns the fraction
of a degree that will show on the screen, I adjust the
getLatitudeSpan() function to pass the same value by dividing it by
1E6. Again that should be combined for production.
LatLonSpans latLonSpans = getSpans();
if (mapView.getLatitudeSpan() == 0)
{
nvps.add(new BasicNameValuePair(latitudespan,
String.valueOf(latLonSpans.LatSpan)));
}
else
{
double latSpan = mapView.getLatitudeSpan() / 1E6;
nvps.add(new BasicNameValuePair(latitudespan,
String.valueOf(latSpan)));
}
also do the Longitude
and latLonSpans = null;
My function returns the percentage of a degree that your entire
screen will show, so I pass the map center lat and lon to the server
with the latLonSpan values and then on the server end, I use almost
the same calculation you do:
int topLatitude = mapCenter (latitude) + (latSpanPassed /2);
int bottomLatitude = mapCenter (latitude) - (latSpanPassed/2);
int leftLongitude = mapCenter (longitude) - (lonSpanPassed /2);
int rightLongitude = mapCenter (longitude) + (lonSpanPassed /2);

Re: [android-developers] Re: Mapping (x,y) to (latitude,longitude)
I think your map center is giving you different values because you are
checking it before it has animated/moved to the new position you have
set... It's the same reason your getLatitudeSpan() was zero at the time.
BUT.. if you are setting the map center anyway, you don't need to get it
from the map, just use the coordinates you are setting the map center
to, OR wait for the map to be finished moving.. and get all the values
from there...
I think it's safe to assume that if your getLatitudeSpan() is zero...
then your getMapCenter() is probably not accurate either... but I don't
know that for sure.
Here's how I call it... The below has a couple of my own functions in it
to set parameters etc... but you would just substitute it for whatever
you need to do. After the JSON object is created I just assign it to
both my Map Overlay and a list view, so I can view the info on either a
Map or in a list.
The line:
sharedFunctions.SendMessage(handler, HandlerReturnMessage, param1,
param2, retStr);
sends the returned string to a handler in the calling activity which
deals with it like this :
The HANDLER IN MY ACTIVITY..
Handler handler = new Handler()
{
@Override
public void handleMessage(Message msg)

try

Then you need to tell them it is impossible. Ask them what the maximum resolution is of the output they desire. And i'm curious which output- device your clients have in mind if it needs a 8192x8192 resolution. Anyway, if it is an HDTV, more than 1920x1080 is not necessary. And if you hook up the phone to an output-device using HDMI, more than 1080p is not supported... If it is an Android phone, more than 854x480 is not necessary. They still can supply you with a 8192x8192 image, but for display you need to scale it down to the display resolution (BitmapFactory.Options.inSampleSize having a value greater than 1).

If you do 'setAdapter', calling notifyDataSetChanged() is not

Override the adapter's getItem and getCount methods and put a break-

But I was referring to MySQL, not the connector. Also, sure there will be also corporates who pay for not using the GPL, but my point was that one is not forced to pay to use it. Now I think we are made clear our points, and MySQL was only an example. And; the INTENT of MySQL is that if you use the GPL version of the MySQL database, your application should also be GPL. But, of course, there are loopholes. However, using these loopholes in a way that is obviously a circumvention is against this INTENT. If you want people to respect YOUR intellectual property, you should respect others as well, and not exploit their software in an unintended manner. Licenses arbitrate how much land each entity has the right to own, in other words they establish borders in a objective way that everybody agrees on, not a subjective or moralistic one. So while I personally might have some interest in what other people are willing to do (subjective and moral position), not everybody is compelled to do that, but only respect the law. Everybody uses licenses to try to place that border in the most convenient possible way. An author of FLOSS software tries to place the border in the best possible position in his perspective, and a user of a FLOSS software has the same right, in his perspective. PS MySQL intent was to make money, and GPL is one of the best way to do that, because of the double licensing thing. In fact, they made a lot of money. Note that the owner of MySQL has changed many times and the intents of the original founders, of Sun Microsystems and Oracle might have been changed. Frankly, if I used MySQL I wouldn't be interested in what their intents are, only in what I can do. - -- Fabrizio Giudici - Java Architect, Project Manager Tidalwave s.a.s. - We make Java work.

[android-developers] Implementing a toolbar/taskbar kind of thing.
Hi, The way we can do it in HTML, where we have two framesets. If I click a link in one frame then only the other frame(target one) is reloaded, the one from which I clicked is not. How this can be done in Android? As in, Say I have a kind of taskbar/toolbar which is part of all views. Is there any way in which Activities from one Frame can switch but activity in other frame remains stable?

[android-developers] Re: Mapping Multiple textures to a cube in Android OpenGL ES
Forget about mipmapping for now - that's a different kind of distortion. I'm talking about taking an image that's 100x100 and putting it into a space that's 150x100, then drawing it back out at 100x100. The user will never know that it was stored at a different aspect ratio because so long as you draw it how it should be, you're good. Here's a good exercise: Create your texture in photoshop or your favorite image editor. Make the texture 1024x1024 and shove 6 different images onto it. Now, drop guidelines down to the edges of the images and switch your info to percentages. Write down all of the percentages that your guides are at. If you do 2 rows of 3, it will be 0, 50 and 100 for the y and 0, 33.3, 66.6, 100 for the x. Those will then become your UVs. Change your cube app to use those hardcoded UVs, eg: // face 0 counterclockwise winding 0,0 0,.5f .333f,.5f .333f,0, // face 1 ccw winding ... Get that working with you manually entering all of the geometry and UV data. Once you figure out how to make that work, you can probably come up with an automated way of doing what you want :) On Jun 27, 3:48 pm, chaitanya vengeance...@gmail.com wrote: Thanks Robert, So in short you are stating that I use a texture atlas approach. The second approach is what I used right now, for every face of the cube construct that side and binding it to the texture which was really inefficient. Well, you have said something about the distortion. I read at nehe's site that you can use mimaps to upload image of any size which will be scaled to the best aspect ratio and will minimize the distortion. Could I use that technique to create the texture atlas? Also, could you give me some pointers or articles which discuss the creation of a texture atlas since I'm fairly new at this. On Jun 26, 12:01 am, Robert Green rbgrn@gmail.com wrote: No, that's not what cube maps are for. You can only draw 1 texture at a time (unless multitexturing but that's totally different and not what you want) so you have 2 options: 1) Combine all textures together into a single one and map the coordinates to each side accordingly (will run much faster) 2) Draw side-at-a-time binding to the appropriate texture for each side. (not usually the preferred method.) A trick many of us use when doing something like... say you want to have the user pick 6 photos from their SD card and then you want to display those on a cube, one on each face. At some point you must load each photo up, clipping and scaling it to fit aspect ratio and a power-of-two texture and then uploading it to vram. Well, instead of uploading each one as a separate texture, why not just create a 1024x1024 bitmap and draw all 6 photos to it in different spots. You could use 50% of the texture vertically and 33% horizontally (for example) to pack 6 photos onto it for 100% usage. It's ok if they distort going on to it so long as you draw them aspect-correct. You then keep track of which one is where (using UVs, so percentages from 0 to 1). Upload that texture atlas as a single texture and when you draw your cube, you just bind to that atlas once and draw everything in one shot. It'll run fast and it's not really that hard to do.

I even mapped multiple textures to different faces of the cube. But the way I did it was to create 6 faces seperately, have 6 seperate index and texture buffers and then using glBindTexture() with the selected texture for each face and then calling glDrawElements. Isn't there an efficient way around this. Should i use a cube map texture instead of a GL_TEXTURE_2D? Any suggestions would be appreciated?

[android-developers] Voice Recognition Libraries - Open Source?
I have an application, Twitoc, in the market that uses Google Voice Recognition to send Tweets to Twitter. The application only works for Android 2.1+ as I believe that is the only platform that has Google Voice recognition libraries pre-installed (I may be wrong). I found that it works on Android 1.5 if you install com.google.android.voicesearch. I found this package from a third party website but I believe it is available in some Android Markets for download (Not Canada as far as I can see). http://uk.androlib.com/android.application.com-google-android-voicesearch-jwAq.aspx My question is that if I find a way to incorporate this into my app, am I allowed to to redistribute it with proper attribution to Google? Is it open-source? I appreciate a response as this would allow me to make this application available to all devices!
