getSupportedPreviewSizes() method. If it does it obtains the width and
height and sets these as the preview size. If the version of Android
is older it will just set it as the width and height returned by the
SurfaceView.
However, it seems the Motorola Droid/Milestone doesn't like this code
and will instead show a blank screen instead of the camera preview.
Could someone kindly tell me where i'm going wrong?

[android-developers] Re: Device Seeding Program for Top Android Market Developers
I'm just speculating here however, it may have been the case that Brightpoint (or whoever distributes the N1 to European providers) needed to stock places like Vodafone before issuing out free handsets. A report today says they are already experiencing N1 shortages and need to await more stock before taking more preorders. (http:// phandroid.com/2010/04/27/nexus-one-stock-runs-dry-for-uk-release/) I cant believe Google would promise us free dev phones and then deny us this opportunity without any explanation. They'll come i'm sure however, the longer we wait the less time we'll have to ensure our apps work well on these new devices consumers are starting to buy. Someone at Google must know exactly what is going on, it wouldn't take 5 minutes to post here and stop all this speculating/moaning/ anticipation.

So ye, this is still a free gift, and i'm as filled with anticipation about getting a Nexus One as the next dev, but if Google screw it up, i don't see them as being bad. It's probably just a delay on the distributor side ( probably BrightPoint ) because they had to stock up Vodafone first.

I think I may know why your app doesn't work on the Nexus. It's to do with setting the preferred size of the Camera view on the Surface View.

Firstly, thanks Mark for taking the time to test it.
The only other thing which could be wrong is how the coordinate system
is represented in each device. I draw to the screen once I have
remapped the coordinate system i.e.:
if(screenOrientation == 1) { // Portrait
SensorManager.remapCoordinateSystem(R, SensorManager.AXIS_MINUS_Z,
SensorManager.AXIS_X, outR);}
else { // All other send to Landscape
SensorManager.remapCoordinateSystem(R, SensorManager.AXIS_X,

[android-developers] Re: IMPORTANT - display.getOrientation() does not work on all devices
Okay can I just summarise my problem as I believe it is an issue which
NEEDS to be addressed...
I have confirmation from five users who either have a HTC G1 or HTC
Magic who say my application works fine. However, I have had numerous
recent comments on the Market that the orientation of my applications
interface is rotated 90 degrees on G1/Magic devices.
I use this method to get the screen orientation:
getResources().getConfiguration().orientation;
and remap the coordinate system as follows before drawing the
application interface:
if(screenOrientation == 1) { // Portrait
SensorManager.remapCoordinateSystem(R, SensorManager.AXIS_MINUS_Z,
SensorManager.AXIS_X, outR);
}
else { // All other send to Landscape
SensorManager.remapCoordinateSystem(R, SensorManager.AXIS_X,
SensorManager.AXIS_Z, outR);
}
How can this work fine on some phones and completely break on other
peoples phones which are the same make and model?
This is really disconcerting, and needs to be explained.

It should either work or not, having your application work fine on
some devices and break on other devices is rediculous and its getting
annoying now.

Firstly, thanks Mark for taking the time to test it.
The only other thing which could be wrong is how the coordinate system
is represented in each device. I draw to the screen once I have
remapped the coordinate system i.e.:
if(screenOrientation == 1) { // Portrait
SensorManager.remapCoordinateSystem(R, SensorManager.AXIS_MINUS_Z,
SensorManager.AXIS_X, outR);}
else { // All other send to Landscape
SensorManager.remapCoordinateSystem(R, SensorManager.AXIS_X,
SensorManager.AXIS_Z, outR);
}
However, this shouldn't be an issue should it?

[android-developers] Re: IMPORTANT - display.getOrientation() does not work on all devices
Hey Mark, I have had one user contact me by email and he had the same issues using the older version and the new version (using the orientation code you supplied), so I can rule out that being the cause *I think*. I *presume* it isn't a ROM issue as I have had 8-10 users leave comments saying it doesn't work, in each comment they say recent update doesn't solve the issue. I guess for most people it may work and they dont bother leaving a message which says hey it works instead its only the people having problems who post negative comments. I have tried every test case such as holding the phone in different orientations when starting the activity and had no luck finding a bug there, in fact I have wasted far too many hours on this.

[android-developers] IMPORTANT - display.getOrientation() does not work on all devices
Hi, I have had several complaints from people with G1 and MyTouch/G2 devices who say my application does not work correctly. The problem stems from the following code which gets the orientation of the phone: // Get Screen Orientation Display display = ((WindowManager) getSystemService (WINDOW_SERVICE)).getDefaultDisplay(); int screenOrientation = display.getOrientation(); I manually rotate the interface if the phone is in portrait (screenOrientation = 0) or landscape (screenOrientation = 1). On my HTC Hero the code works fine and the correct orientation is determined, however on G1 and MyTouch devices it apparently never returns the correct orientation. As I do not have either of those phones to test this problem I am guessing they may return the opposite values to the HTC Hero? Can anyone possibly explain this problem or let me know how to determine the screen orientation on ALL devices?

[android-developers] Using sensors and orientation - lat/lon point to screen coordinates
Hi,
I want to find the screen coordinates (X,Y) where a point represented
by a latitude/longitude value would appear on the screen if you
pointed your phone at it (much in the same way as Wikitude does).
Here is my code from my onSensorChanged() method:
public void onSensorChanged(SensorEvent event) {
Sensor sensor = event.sensor;
int type = sensor.getType();
switch (type) {
case Sensor.TYPE_MAGNETIC_FIELD:
mags = event.values.clone();
isReady = true;
break;
case Sensor.TYPE_ACCELEROMETER:
accels = event.values.clone();
break;
case Sensor.TYPE_ORIENTATION:
orients = event.values.clone();
break;
}
if (mags != null accels != null isReady) {
isReady = false;
SensorManager.getRotationMatrix(R, I, accels, mags);
SensorManager.remapCoordinateSystem(R,
SensorManager.AXIS_X, SensorManager.AXIS_Z, outR);
SensorManager.getOrientation(outR, values);
azimuth = convert.radToDeg(values[0]);
pitch= convert.radToDeg(values[1]);
roll = convert.radToDeg(values[2]);
}
}
I convert the points I wish to project from their lat/lon spherical
coordinates to Cartesian coordinates and perform a perspective
projection using the roll, pitch and azimuth values returned by the
sensor, however, I can never seem to get accurate screen coordinates
of the points.
The matrices for roll, pitch and azimuth I use are:
// pan
double[][] azimuthMat = {
{Math.cos(azimuthValue), -Math.sin(azimuthValue), 0},
{Math.sin(azimuthValue), Math.cos(azimuthValue), 0},
{0, 0, 1},
};
// tilt
double[][] pitchMat = {
{Math.cos(pitchValue), 0, Math.sin(pitchValue)},
{0, 1, 0},
{-Math.sin(pitchValue), 0, Math.cos(pitchValue)},
};
// roll
double[][] rollMat = {

[android-developers] Re: Using sensors and orientation - lat/lon point to screen coordinates
The main problem is when I use the values returned by the sensor
manager as is i.e. not modifying them in any way, the points are no
where near where they should be. For example, say the point I wish to
project is due north of my current location and at the same elevation.
I shouldn't need to tilt (pitch) the phone up or down and when I hold
the phone in the direction of north it should appear somewhere near
the center of the phone screen. However, this is not the case, in
reality for the point to appear on the center of the screen I need to
do something like tilt the phone at the ground and orient it in a
easterly direction for example.
I have made a nasty fix which means I subtract 90 from the roll or add
45 degrees to the pitch etc. However while this now projects the point
on the center of the screen it ruins the projections of any other
points (as I have fundamentally altered the sensor values). In my
current implementation a point north of me may work but any points to
the south do not work.
My problem is probably something to do with the coordinates of the
phone differing from my projected coordinates, but making the two
work together is causing me some serious headaches.
I can send you my projection code if it helps, I have really exhausted
all ideas to solve my issue!

Does it not work *at all*, or does it work basically, but points are

Peli, I think I love you :)
No seriously, I changed:
SensorManager.AXIS_X,SensorManager.AXIS_Z,
To
SensorManager.AXIS_Y, SensorManager.AXIS_MINUS_X
and it basically works, its slightly out but I am almost sure its down
to my projection code being slightly wrong ;)
Three days of bother and one line of code solved it...
I'll reply again if I run into any more problems (so please check
back :D).
Thanks again!

A couple of possible issues come to my mind:
* Did you make sure that your compass is calibrated? (figure 8 in the
air with the phone several times in various directions)
* Are you far enough away from computers, steel, loudspeakers, or
other objects that may deflect magnetic field lines (and thus alter
the compass readings)?
* For a change portrait - landscape, it would make more sense to
remap x and y coordinates by 90 degrees, rather than swap x and z
coordinates, like SensorManager.AXIS_Y, SensorManager.AXIS_MINUS_X,
If all of these don't help, it is more efficient to print out (logcat)
the sensor values, and try to solve one problem at a time (like, first
get the correct orientation values from the compass, and if that
works, then look into your projection routine), rather than solving
the whole stack of possible error sources at once.
Good luck :-)

[android-developers] Re: MapView balloon box, is it possible??
I believe you have to create your own balloon box and draw it to the screen above the tapped marker. I am not aware of an in-built mechanism to achieve this. It shouldn't be too hard to create one though, just use a .9.png for the background etc, so the marker expands automatically to contain the desired text.

[android-developers] Detecting when a MapView is changed (panned or zoomed)
Hi, I thought this would have an easy answer but I cant seem to find one. Does MapView have a mechanism such as an onChange listener which is fired when the MapView is either panned or zoomed? I have expermiented with onClick, motion events etc, all are not really what i'm after. I just need to know when the state of the MapView is changed by the user zooming or moving it.

[android-developers] Re: Detecting when a MapView is changed (panned or zoomed)
Im still struggling with this... I create an overlay and add it to the MapView, then i override the onTouchEvent to capture all the panning movements made. However, while this reads all panning movements the map no longer pans. Its as if, I have replaced the defualt MapView onTouchEvent with my own. How can i fix this?

[android-developers] Seekbar - Snap to value
Hey, Quick question... Is there a way to define set values (i.e. 0%, 25%, 50%, 75%, 100%) for the seekbar widget that enables the slider to snap to the nearest set value? For example instead of allowing the user to position the slider at an percentage through 0-100, instead the slider can only ever be positioned at one of the five set values? Oh and while were on the subject is there an easy solution for positioning the seekbar vertically, i'd rather not hack through the seekbar source code - but I fear I may have to!

[android-developers] Re: Android Physics Engine
to Android as well. This demo was more of a calibration for myself to see how much computation I can do, and what optimizations lead to the largest improvements. I'll probably turn it into a fun toy for the Market and then look into rewriting my rigid body engine for Android. Reading through Simpull I noticed that you allocate a new Vector3f in your Verlet update routine. I think that will be a killer on the Android platform because of it's rudimentary garbage collector and limited RAM. My solution was to allocate an array of fixed point numbers, four per ball. Effectively a vector pool that didn't require any management because the number of balls never changed. On Apr 2, 6:31 am, shaun shashepp...@gmail.com wrote: I took a look at Anton's demo on a G1 device, and I was glad to see the integration of accelerometer as it really added value. I assume the calculations for collision detection and response are fairly basic, which allows for that performance. Simpull will also provide good performance for a scene of that nature (all verlet, no joints). At least I believe it will. The point where simpull becomes slow is when a more complex scene is in play with 10s of objects with many joints connecting some of them. Since the engine is all verlet and no rigid body dynamics, joints are one way to acheive a similar result, but with a very bad performance hit due to all the new temporary objects and new calculations. I would be super impressed to see a demo like Anton's with rigid body dynamics involved with at least some rectangles, if not other polygons and perhaps a joint or two. That is where the performance degrades quickly in my experience. On Apr 1, 2:45 pm, mscwd01 mscw...@gmail.com wrote: Thanks Lajos for pointing APE out, I hadn't heard of it until now.

I have a 2D rigid body physics engine that is currently all C++ (no exceptions or templates or RTTI or multiple inheritance) that I may port over as well. However, having said all of that, I think it may be the case that we will just have to wait until a native SDK is available to really write a top notch physics engine. It's sort of the perfect example of a piece of code that doesn't need anything more than libc and JNI bindings. And since you only call it a couple times per frame the JNI overhead would be well amortized.

Having said that Anton (2nd reply) has said he has an engine running, it would be nice to see a demo of this if that'd be possible? Clark, i'd definately host any .apk's on my own site, I wouldn't put it on the marketplace if it wasn't a finished app - do people actually do that?! I think i'll stay away from developing games with physics for the time being and concentrate on something else, I cant see it being feasible to include it any time soon which is a real pity.

[android-developers] Re: Android Physics Engine
I did take a look at Simpull, however the demo application failed to run as it relied on some library which wasn't supplied or referenced to - I just got annoyed after spending two days failing to get Phys2D and JBox2D to work in Android and didn't bother trying to work out the problems! I might give it another look though...

[android-developers] Re: Android Physics Engine
Oh I forgot to re-ask... Has anyone tested Phys2D or JBox2D on an actual device to see if they run better than on the emulator? I have a feeling the performance will better on a G1 than the emulator for some reason!

[android-developers] Re: Android Physics Engine
I'll try and wrap my Phys2D JBox2D examples into a .apk sometime. I'm very busy at the moment though so it may be later in the week by the time I get to do it. I'll provide a link in this thread if I get to do it. Other than that, i'll have to wait until the HTC Magic is released soon ;) On Mar 31, 2:49 pm, admin.androidsl...@googlemail.com admin.androidsl...@googlemail.com wrote: Not tried but if you can provide us with some example source code or put something on the market, I'm sure we could take a look. G1 performance is significantly faster than emulator, but there are limitations. Particularly with garbage collection and memory allocation on code that gets run continuously in loops, so I don't know how optimised these physics engines are for this purpose. Would be interesting to find out though. On Mar 31, 12:52 pm, mscwd01 mscw...@gmail.com wrote: Oh I forgot to re-ask...

[android-developers] Accuracy of sensors such as electronic compass
Just a quick question... I am now beginning an app which will use the compass and tilt sensors to determine a persons heading and line of sight. Can I assume the sensors on devices such as the G1 are fairly accurate or can I expect to run into problems such as the compass being 5-10 degress off etc?
