Android :: Level Of Detail For 3D Terrains / Models In Mobile Devices
Jun 6, 2010
I am planning to develop for WP7 and Android.What is the better way to display (and traverse) 3D scene/models in term of LoD? The data is planned to be island-wide (Singapore).
1) Real-Time Dynamic Level of Detail Terrain Rendering
2) Discrete LoD
3) Others?
And please advice some considerations/algorithms/resources/source codes. something like LoD book also Okay. Side note: I am a beginner in this area but pretty well-versed in C/C++. And I haven't read the LoD book.

Ever since Google started allowing offline maps (both in the old Google Maps incarnation, and in the current one), I have found that when I download a map section for offline viewing, often there are many details missing (small street names, for example).
Any way to make Google maps download map tiles to their maximum level of detail (the level you could get if you zoomed in all the way), including all street names? You'd think this would be a given, but it seems not to be.
Searching around for discussions of this, most articles and forum threads are just about tile caching in general, not level of detailed cached.

I'm trying to connect to connect to my T-Mobile G1 to test a simple android app I an creating. I cannot get it to show up in the list of connected android devices. Here are the details: - 32-bit Windows XP - I have enabled USB Debugging on my device - I am not prompted with the New Hardware Wizard when I plug my device in, it is merely seen as a new removable drive. It does not appear under any other categories in Device Manager, nor is there a new "Unknown Device" entry anywhere to be found - I have tried "Update Driver" and select the driver that Google provides for their official developer devices, but it says "this driver does not match your device" or something to that effect. Probably because it is expected a device type other than "Disk Drive" - I have tried uninstalling the device under "Disk Drives" and plugging it in again but it always gets reinstalled automatically as a "Disk Drive" - I have tried uninstalling the device, manually installing the Google driver from the INF file and plugging in the device and it is still only recognized as a "Disk Drive" - Most importantly, I get a blank device list when I run "adb devices" from the Android SDK tools directory before and after each step I tried After hours of scouring the web I get the distinct impression that a new device category should be popping up in Device Manager if the driver is installed correctly, but I have not been able to get the device to come up as anything other than a new "Disk Drive"

I'm having trouble developing an app, while it works in API level 10, it does not in API level 7. I wondery why and I've been looking for a site that summarizes the differences, or the new features from one API level to another and cannot find it.
09-04 04:24:21.485: E/AndroidRuntime(6834): Uncaught handler: thread main exiting due to uncaught exception
09-04 04:24:21.510: E/AndroidRuntime(6834): java.lang.VerifyError: [code]....
There seems to be a problem with an uncaught exception and reflection, although....why does it work on API level 10?

I don't see the logic behind this. The more people who watch hulu means more people who are looking at ads. And the more people who look at ads, the more money hulu makes. The only logic I could see behind this is that a Hulu Plus app is coming to the Android market, but I haven't heard anything about that.What's your take on this?

I have been using LibTomCrypt to use SHA1 encryption ( for data integrity checking ) on mobile devices (iPhone OS and Android for the moment ). I was wondering if anyone is using anything else, things to consider are Portability ( C preferred but C++ is also an option ), and libraries size ( small == better for my particular needs ).

I've a very simple static web page (only css and links, no scripts).
It looks good on android and iphone, but too small. I'm guessing they put it smaller since it work for most of the sites.
How can i override this and make him look the size i want it to be?

I'm trying to write a program that manages a form of messages, and these messages are received from an external data source. This all works. However, the problem comes when I try to notify the user: I would like to have the notification jump directly to the message when it is touched, but this seems to mess up the back stack. This is probably best explained by example:
I open up the message list, the main activity, and browse for a while.
I hit home and go into another app (let's say Music).
A new message is received. A notification comes up, which I touch. The message detail view is displayed.
Now I hit Back. What I want to have happen is that I return to Music, but unfortunately, Back sends me to the message list, and then hitting Back will return me to music.
The both the list and the detail activities are marked as "singleTop", and the exact flags that I use for the notification Intent are:
FLAG_ACTIVITY_NEW_TASK
FLAG_ACTIVITY_CLEAR_TOP
FLAG_ACTIVITY_SINGLE_TOP
I figure if the Messaging application can do this, why can't I?

I've managed to get some basic 3d stuff working quite nicely on my Android device. My question is how do you define/create more complicated 3d models? Obivously using int[] arrays of vertices hand written is quite time consuming and error prone. Are there any modelling tools that can be used?

As I understand, currently there exist two of them, to relieve devs from implementing their own ones, which are -strict -servermanagedpolicy However, I'm missing a predefined policy that actually is the counterpart to the soon deprecated "copy protection mode", ie one that will check once, and then keeps silent for weeks or even months, instead of harassing users to make an online connection. So, I'd like to request to please add a third predefined policy to cater to our laziness. A policy that is the counterpart to the actual old 'copy protection' thingy. Apart from this I don't really see why an app that has been correctly installed by the market with device-based signature checks and all really needs to be checked every 5 days? Wouldn't that only make sense if the app is sort of subscription-based?

I'm watching the 2010 Google I/O video on this topic and I have a few questions to make sure I understand properly. Google I/O 2010 - Android REST client applications Please note I also have a very limited understanding of CursorAdapters Right now my application just has a UI layer. I've created an object called DbAdapter using some Google tutorials to create a small database and a table in that database. I've created a class I'm calling DataBroker (extending ContentProvider) to manage retrieving data from the database and calling web services to update data. Scenarios:
1) Suppose I want to display a list of items in my ListActivity. Am I correct in assuming I will write a function in my DataBroker that creates a Cursor to the table in my database that holds those items, fire up a service which launches a thread which calls a web service to get additional items, then return the Cursor to my UI thread? Doing this would likely return the Cursor to my UI thread before the web service finished, but, I'm assuming, once the CursorAdapter has a Cursor, it will automatically show any changes made to that database table, yes?
2) Now I have a list of items in my ListView. Suppose I give the user some functionality to delete an item. The user executes this functionality. It should call a function in my DataBroker which updates the row in my database corresponding to that item, setting the status column to STATE_DELETING (which will remove the row from the ListView because the Cursor has a clause excluding this state), then fire off a service that fires a thread that hits my web service, then deletes the row in the database when finished? Also, suppose I have multiple Activities, am I looking at having a static Cursor for each Activity with a list, grabbing that Cursor in the Activity's onCreate, and if that Cursor is null, hitting my DataBroker?

I have just started on a new application that will use SQLite for persistance and Im a bit confused over the usage of a context when utilizing the SQLiteOpenHelper.
I have a base class called Storable, which my models extend if they need to be persisted. i had intended to use a synchronized singleton database adapter, but I can't for the life of me understand how to utilize the SQLiteOpenHelper as it requires a context, which my models don't appear to possess.
I'm aware that I can get around this by not using the SQLOpenHelper - but if this restriction is in place, I would assume its to prevent people creating apps "the wrong way" for android.
What is the best practice way for saving models in the database?

Can anyone tell me if it's possible to add more detail to your phone book entries if your inputting them manually? My facebook account is for networking and promotion, so a lot of people I have in my friends list I don't even know. Because of this I have had to remove my account from "facebook for htc sense". Unfortunately I liked the way it had lots of info for each individual contact, photo, birthday, email addy etc. Is their anyway of having this much info for each individual entry when adding them in "people"?

I recently added a feature to my app that allows the user to send a report via a message chooser (all have chosen gmail) that helps mitigate the fact that I don't have all the physical phones to test on. Execution worked as expected on my G1 and the emulator, however, to my horror as users began sending them in most of them were incomplete! Pseudo-code of what I am doing is as follows: On my phone and the emulator, all of the packages are inserted into the email. However, most of the emails I get, even from the same exact phone model/carrier/OS version, only contain "Text1". Users that have automatic signature insertions even have that at the bottom, so it's not that the email is being cut off somehow, it's that size is apparently 0. That is the only thing I can think of. Every once and a while I will get a full email though. This frightens me because what other APIs run fine in my testing but not user phones? What's going on here?
