Android :: Floating Point Support On G1 Phone

May 17, 2009

I have been searching about the floating point support on G1 phone (aka the HTC Dream phone) for a few hours.

So far, my conclusion is that the ARM-based Qualcomm MSM7201 CPU does not have VFP (floating point coprocessor) and therefore floating point calculations have to be done via software-float.

This is quite disappointing as I am interested in developing applications with heavy math.

However, I also notice that the Qualcomm CPU has QDSP4000â„¢ and QDSP5000â„¢ high-performance digital signal processors (DSP), according to http://www.qctconnect.com/products/msm_7201.html

Therefore, here is my question: would it be possible to leverage the DSP modules in the MSM7201 CPU to do the floating point math?

Also, I would like to develop the heavy-math modules in C/C++ and call it via JNI, and so I just want to double-check whether this is a feasible approach.

Android :: Determine Phone's Proximity To Known Point While Conserving Power

Jun 14, 2010

I am trying to determine if an Android user has had a close proximity to a list of predetermined locations. I'd like to do this with the least amount of drain on the phone's battery. The two mechanisms I see for accomplishing this are proximity alerts and requesting location updates. What are the pros and cons of the two methods? Will one have less affect on the battery than the other? In either case I would guess the specific location manager used would have some affect power usage (existing Stack Overflow answer).

Samsung Galaxy S :: Phone Wireless Access Point Deactivated

Nov 4, 2010

I have a samsung galaxy S i9000, and the mobile access point is activated, I can successfully connect to it using my laptop but when I try to connect using my other mobile (ex: Nokia) to the Galaxy's mobile access point on the target device it says the wireless connection is lost and on the Galaxy the mobile access point is deactivated automatically, is this a limitation that the other device cannot be a WiFi mobile (Which I don't think)? OR is this a bug in Galaxy's mobile access point.

Motorola Droid X : Poll - Biggest Talking Point With Phone Seems To Be Size

Jun 16, 2010

The biggest talking point with this phone seems to be the size. Id be curious to see some numerical opinions! I myself have been waffling: at first I thought "Oh, way too big". Then this picture made me think its not the much larger than similar phones and I was getting it for sure! But this pic has me wondering. Looks pretty giant in her hand:

So: What do YOU think about the size? If you havent seen yet, engadget has a gallery of 50 some pictures.

Android :: How To Update Access Point?

Oct 13, 2010

I have successfully programmed insertion & deletion of an Access Point in database but I need to find out how to update an access point. I'm using db.update() but its not producing any result. I am using the following code to update an access point:

ContentValues updateFields = new ContentValues();
ContentResolver resolver = getContentResolver();
updateFields.put("name:", "AIRTEL");
updateFields.put("apn_addr", 11023);
resolver.update(TABLE_APN_URI,updateFields,"_id=?",new String[] {Long.toString(2)});

While updating I'm not getting any error as well.

Android :: Point Sprite Support

Oct 5, 2009

Can someone confirm for me that point sprites are not currently supported in Android? Calling gl.glEnable(GL11.GL_POINT_SPRITE_OES) is triggering a GL_INVALID_ENUM error, so I assume this is the case, but I'd appreciate a confirmation before I proceed with an alternate design.

Android :: Calculating Direction From Point A To B

Sep 17, 2010

I'm trying to create a compass for my application BUT the difference is that, instead of having a line always pointing to north, I want this line to point for a specific point. I've been trying dozens of algorithms and nothing works. I've finally found one that points me exactlly to the point I want. But it doesn't move if I change the position of the device which is my objective. Basically, what I want is that no matter the direction I'm using my device. The line always point me to the point (picLatitude,picLongitude). I understood that for the line to move, I can't use static variables. I need to use the values offered by the onSensorChanged(SensorEvent event). This are the data I have available:

event.values[0]: azimuth, rotation around the Z axis (device in relation to north, 0º) event.values[1]: pitch, rotation around the X axis event.values[2]: roll, rotation around the Y axis mLatitude: device current latitude got from GPS (variable) mLongitude: device current longitude got from GPS (variable) picLatitude: static picture latitude established previously picLongitude: static picture longitude established previously distance: distance in Km from device to the picture calculated previously

And this the formula that works correct, and gives me the correct angle. (But it doesn't use any of the Sensor Data so the line Compass doesn't move):
double dLong = picLongitude - mLongitude; double y = (Math.sin(dLong) *
Math.cos(picLatitude)); double x = (Math.cos(mLatitude) * Math.sin(picLatitude) - Math.sin(mLatitude)*Math.cos(picLatitude)*Math.cos(dLong)); double angleDegreesWrongRange = Math.abs(Math.toDegrees(Math.atan2(y, x))); float angleDegrees = (float) ((angleDegreesWrongRange+360) % 360);
myCompass.updateDirection(angleDegrees);
I got this "bearing" formula from this website: http://www.movable-type.co.uk/scripts/latlong.html. I've try adding, subtracting, the azimuth.. I've tried with the others, seriously at this point I'm just demoralized.

Android :: What Is The Starting Point For Animations

Jul 19, 2010

I am at a stage where I can understand and write a decent Android application. At this stage, I am still not comfortable with SurfaceHolder, Canvas, View invalidate() etc. I don't have a CS background so I must've missed these from a CS Graphics course or something.

Starting directly with Android seemed like a bad idea because there are not many examples out there. And sometimes I am getting things done, but I don't understand what the heck is going on. For instance, there are a few dangling observations. Calling invalidate() from within a view calls its onDraw method but from outside it doesn't do anything and I don't know why this is happening. I know SurfaceHolder can be a powerful thing but I don't know how to use it.

For an absolute beginner to be able to handle this stuff, what are the resources one should follow? Is it animation basics or screen rendering or something else altogether? I mean, it cannot be the case that Android guys invented these concepts right? They must be similar to something out there which has some tutorials already. My end goal is to put myself in a position where I can write some simple custom views that can animate themselves and use some basic physics to react to touch events.

Android :: Get Notified When New Access Point Is Added?

May 26, 2010

I was wondering is it possible to get a notification of when a new configured network is added to the Wifi Manager in Android? I know you can get the current list of configured networks.

But is it possible to get notification of when a new one is added? I don't see anything in the Wifi Manager that would be helpful. How this could be achieved?

Android :: OpenGL ES Fixed - Floating Point

Oct 13, 2009

I've started developing an OpenGL ES app and I would like to get the best possible performace (as everybody, I guess).

As far as I know, HTC Magic (myTouch, G2) doesn't have floating point unit, so I think every calculation is done internally with fixed point math. That beign the case, altough I fed OpenGL with floating point vertex positions and normals, there would not be any permormace penalty since it would be using integer math instead of floating point emulation.

Android :: Floating Point Hardware Support?

Feb 22, 2010

I'm currently developing a application on a HTC Dream aka T-mobile G1. afaik the processor has a FPU coprocessor, called VFP (Vector Floating Point) in ARM terms. So far I couldn't find any information about if the FPU is used for floating point calculations or if those are emulated in software. does anyone have any information about that? the opengl implementation supports both fixed point and floating point. will my applications be slower when I'm using floating point, because they get transformed into fixed point internally? or is floating point implemented in hardware?

Android :: Open GL Fixed Vs Floating Point?

Jan 6, 2010

OpenGL ES allows values to be specified in either fixed point or floating point format, but I haven't been able to find any information about how this is actually implemented on Android devices. Are there actually two different pipelines, one for fixed point and one for floating point? If so, what happens if you mix and match them, such as specifying your matrix in floating point but your vertices in fixed point? Alternatively, does it implement everything with just one format internally, and convert the other format to it as necessary? If so, then you presumably get the best performance if you always specify values in the internal format so as to avoid conversions. How then can I determine which format is used internally?

Android :: Math Floating Point Library

Jan 12, 2010

I need maths for my game physics and lots of them, so I use the. Math library. And guess what? I never casted so much to floats in my entire life. And i know how costly it is to use doubles on an embedded device because I read the performance optimization page in the google android sdk docs. So I am wondering if we couldn't get a Math package with functions taking and returning floats instead of the default doubles. e.g. Math.sinf Math.cosf.

Android :: Get Notified When A New Access Point Is Detected?

Nov 23, 2010

Does Android provide a notification of being in vicinity of a new Wifi Network? Whether the device is configured to connect to that wifi network depends on whether the device has the wifi configuration set for that particular wifi network, but is it possible to get notification whenever entering any new wifi network?
I saw the WifiManager class but the states inside the class do not seem to achieve what I am trying to do. Any ideas?
