Android :: How Do I Define / Standardize Units In My 3D App?

Mar 20, 2010

I'm starting to design my object graph for an OpenGL ES 1.1 app on Android. What's advisable when it comes to actually drawing my triangles and controlling their size? Should I store all the vertices in units relative to each other and then multiply them by a value I pass during a draw(GL10 gl)? Would this approach have any impact when it comes time to do frustum culling?

Android :: How To Get Maps In Metric Units?

Jul 8, 2009

This may be in the wrong forum, but I can't figure out where else to post it.
The maps app (the one from google your phone comes with by default) only shows routes in feet and miles. Is there no way to get it in meters? I can't find any settings for this!

Android :: What Are Units Of Event.values?

Aug 23, 2009

I am experimenting with orientation sensor, register it like this: SesnorManager sensor_manager = (SensorManager)getSystemService (Context.SENSOR_SERVICE); Sensor sensor_orientation = sensor_manager.getSensorList (SensorManager.SENSOR_ORIENTATION).get(0); sensor_manager.register Listener(sensor_listener, sensor_orientation, SensorManager.SENSOR_DELAY_UI); and then read the orientation values in the sensor event listener: private final SensorEventListener sensor_listener = new SensorEventListener() { ... float sensor_data_x = event.values[SensorManager.DATA_X];}

General :: How Many Storage Units Android OS Have

Nov 2, 2012

How many storage units Android OS have? Including a possible microSD external Card.

Internal Storage, internal memory?! Whats the difference and location in file system folders?

When an app is installed from market where does it go?

In application manager, in most apps there is an option "Move to SD card"...

If I have an external micro SD Card and choose this apps option "Move to SD card" where the heck is suppose to going the app or some part of it? (Data? Apk? Cache?) It's not in external microSD Card! So what is "Move to SD Card".

Android :: Isolating Units / Writing Tests

Jul 23, 2010

My project has the run-of-the-mill HTTP calls to fetch XML files, parsing the XML files, and creating domain objects. Those objects are later used in the actions and services of the Android app, I'd like to isolate that code. I also want to write tests for it. What are some good ways of doing this? Creating an Android Library doesn't seem appropriate. The tests would have to be in a separate project. And there are no services or activities in the extracted HTTP and XML related code. So the test suite doesn't have to be an Android test suite, it could be regular JUnit tests.

Android :: Location Distance Between Units / Emulator

Feb 24, 2010

1) I have not been able to find out in which units Location.distance Between receives the latitude and longitude. Is it degrees or micro degrees? Whats the unit for the distance returned? 2) In windows XP using Eclipse 3.3.2. Emulator does not send coordinates properly. Either it by hand or by loading a gpx file the location Listener is not invoked. This same code I have tried it in Ubuntu and works fine. Does someone know how can I solve this? In the office there is no linux installed and I can take my personal laptop.

Android :: Maximum Texture Units - Emulator Setup

Apr 30, 2010

this is just an issue with how the emulator is setup, but I'm not sure.

I'm (natively) calling this:

int maxt = 0;
glGetIntegerv(GL_MAX_TEXTURE_UNITS, &maxt);
__android_log_print(ANDROID_LOG_VERBOSE, "Native", "Max textures %d", maxt);

This only outputs 2... could it be possible that I'm going to be allowed only 2 textures? That seems impossible... GL_MAX_TEXTURE_SIZE reports 4096 which is more than enough. I suppose you could lay everything out on a couple of 4096x 4096 images (seems a bit crazy) but anyway... Am I just running into one of things that will be different per phone processor?

Android :: Define A Screen Resolution

Dec 12, 2009

With Android, you can define different resources for different phone attribute by naming res directories appropriately. I need to be able to support different layouts for 480x800 and 480x854. I figured I could have one set of resources stored in the layout-hdpi-v4 directory and another in layout-long-hdpi-v4. However, both resolution seem to think that they are long (at least based on the emulator, which I understand may not reflect devices accurately). Is there another way in which I can distinguish between the two resolutions/aspect ratios?

Android :: How To Define GPS Module In Phone

May 16, 2010

I'm porting android to Devkit8000 which is a BeagleBoard clone. I have a GPS module connected on /dev/ttyS0. I could successfully get NMEA output when writing "cat /dev/ttyS0" in the terminal emulator.

I want to know how to let android know that there is a GPS module on /dev/ttyS0 and it is outputting NMEA standard? To be able to use the android.location class with it! or test it with any GPS app in the store!

Is there something to edit in the android's source? adding driver for example, writing a code with android-ndk or what?

Android :: Possible To Define Each Tab's Content In A Separate XML File?

Jun 28, 2010

I would like to define each tab's content in a different XML file so the visual editor in Eclipse can be used. That is, without all of the tabs being laid over each other. The visual editor doesn't even seem to work with the XML example provided here: [link text][1]
[1]: http://developer.android.com/guide/tutorials/views/hello-tabwidget.html "Here", It just has a Null pointer exception.

I have tried to define each tap in it's own file, for example. code...
And when adding the tab I use:

mTabHost.addTab(mTabHost.newTabSpec("tab_in").setIndicator("Input").setContent(R.layout.input));

But this causes the application to crash on launch. Is there any way to do this?

Android :: Define A Circle Shape In Droid Xml Drawable File

Jul 6, 2010

I have some problems finding the documentation of the definitions of shapes in XML for Android. I would like to define a simple circle filled with a solid color in an XML File to include it into my layout files.

Sadly the Documentation on android.com does not cover the XML attributes of the Shape classes. I think I should use an ArcShape to draw a circle but there is no explanation on how to set the size, the color, or the angle needed to make a circle out of an Arc.

Android :: Define Default Framebuffer Driver For Droid Kernel?

Jul 6, 2010

I'm porting android to an overo gumstix. thus it seems the the omapfb driver has some problems on that platform. it doesn't matter at all, because i want to use udlfb (a driver for usb displays) anyway.

till today, i wasn't able to figure out how i can define udlfb as default framebuffer.
tried make menuconfig and select udlfb there, but no changes when booting the fresh compiled kernel. omapfb still wants to come up.

so my final question: how do i define
the default framebuffer driver for an
android kernel?
