I have implemented a routing protocol on an Android 1.6 mobile that uses wireless (ad-hoc) network in order to exchange messages. Now I would like to evaluate it under an energy consumption point of view, the base would be to try to calculate the energy wasted to transmit a single packet, do anybody has any idea how to do that? Software/hardware solutions are welcome! Thanx :)

I've looked up and down the SDK for this, but I can't find anything. I'm wondering if there's a way to transmit a sound, such as a WAV or OGG, during a call such that the person on the other end can hear it. (This sound should be heard in addition to, not in place of, the normal voice transmission.) Is there a possibility I may have overlooked?
View 1 Replies View RelatedI am using a Java application to send UDP packets to an Android device. There I have another Java application that receives these UDP packets and displays its data - very simple.Now I am working on some routing algorithms - therefore it would be nice to know how many hops a UDP packet did since it was send. My idea is to just read out the TTL (time-to-live) value of the packet and display it. Do you know if this is possible with pure Java? The class DatagramPacket doesn't give any hints at all.I guess that this is not possible because this information might already have been removed at a lower layer, but I just want to be sure. :-)
View 2 Replies View RelatedI'm wondering what color-scheme is more energy-saving for AMOLED display? I've already decided to manage c-scheme according to ambient light, thanks to this post: Somewhat-proof, the link posted by nickf: Ironic Sans: Ow My Eyes. If you read that in a well lit room, the black-on-white will be the most pleasant to read. If you read it in a dark room, the white-on-black will be nicer.But if I want to save battery power, should I use bright content with dark background or vice versa?Is it possible anyway (they say it's not working for simple LCD)?

The only way to connect to the Internet is through a VPN connection (PPTP), but it bothers me a bug in Android.The error I'm getting in the log is as follows:
Creating PPPoX socket
Socket () Protocol not supported.
I found a patch for it, and the manufacturer provides kernel available for download.Patch is here: code.google.com/p/android-x86/issues/detail?id=451...I tried to manually apply patch. I replaced some code in files if_pppolac.hi if_pppopns.h. But I do not know how compile kernel
I also tried to install latest fw update, several alternative ROMs and several VPN clients but nothing worked. always the same error: Socket () Protocol not supported. The best would be if I could put Jelly bean on box. In Jelly Bean pptp works fine.
Has anyone tried to do a tcp client server app using the emulator using the pc as a server and the phone as the client?I've got a bit of an issue where its only sending one packet, ie 1491 bytes of data regardless of how much there actually is to send, from the client(Phone) to the server(PC).

Code:
private void spawnSpaceship() {

spaceship.width = 32;
spaceship.height = 32;

As part of my Android app, I'd like to upload bitmaps to be remotely stored. I have simple HTTP GET and POST communication working perfectly, but documentation on how to do a multipart POST seems to be as rare as unicorns.
Furthermore, I'd like to transmit the image directly from memory, instead of working with a file. In the example code below, I'm getting a byte array from a file to be used later on with HttpClient and MultipartEntity.
CODE:..............
This all seems fairly clear to me, except that I can't for the life of me find out where to get this ByteArrayPartSource. I have linked to the httpclient and httpmime JAR files, but no dice. I hear that the package structure changed drastically between HttpClient 3.x and 4.x.
Is anyone using this ByteArrayPartSource in Android, and how did they import it?
After digging around in the documentation and scouring the Internet, I came up with something that fit my needs. To make a multipart request such as a form POST, the following code did the trick for me:
CODE:.....
The HTTPMultipartMode.BROWSER_COMPATIBLE bit is very important.

View 1 Replies View RelatedI was wondering if there was an app or indeed if the Desire has the ability to transmit a low powered signal on FM?
You know how some Nokia phones can transmit a weak signal on FM so that if you are playing an mp3 or listening to an Internet stream on your phone you can pick it up on your car stereo and listen through that.
Obviously this phone receives FM radio but does anyone know if this phone can transmit FM as well? That would be soo handy.

View 1 Replies View RelatedI need to calculate a rotation vector out of the data i get from Sensor.TYPE_ORIENTATION. The sensor data is defined like this: the values have to be recalculated to become a correct 3d position: values[0]: Azimuth, angle between the magnetic north direction and the Y axis, around the Z axis (0 to 359). 0=North, 90=East, 180=South, 270=West values[1]: Pitch, rotation around X axis (-180 to 180), with positive values when the z-axis moves toward the y-axis. values[2]: Roll, rotation around Y axis (-90 to 90), with positive values when the x-axis moves away from the z-axis need all three values like the Z axis value (from 0 to 360 degree). I tried a lot but cant figure out how to do this :/ So i bet there is a simple solution how to recall the values of sensor.TYPE_ORIENTATION to make them a 3d rotation vector, but i just dont know how to do it. If you know the answer please tell me. Code...

When I declare a TextView, is it possible to calculate how much space (height and width) it is going to take when actually rendered on the phone?
I have noticed that based on the different screen sizes of phones (or density), the TextView is rendered accordingly. I want to be able to calculate the exact height and width rendered.

So I'm developing an app for android, and before I get too much into it, I want to conceptually get my arms around what I am trying to do. Is it very difficult to calculate or track the most frequently accessed apps? Any ideas or insights about how I might go about getting this done would be greatly appreciated! I'm used to iphone development, and am quite new to the android platform.
View 2 Replies View RelatedHow to calculate the date difference in Android?
View 1 Replies View RelatedIn my app I am displaying a table where the individual cells are editable text fields (i.e. EditText objects). I am currently struggling calculating appropriate widths for these.
If I set the width to be as many "Ems" as the displayed text has characters, my fields are much to wide by about a factor of 2 and the table looks ugly and wastes lots of precious screen space. Setting the width in "Ems" is essentially like assuming the worst case, i.e. the width of a string under the assumption that it contains only the broadest characters in a font, usually 'M' (hence the name of the method), 'm', 'W', or '_'). But on average strings contain narrower characters and so most of these fields are half empty and much too wide for their actual content. I am thus desperately seeking a way to calculate a better fitting width, not that worst case width.
The "normal" way to do this in Java (in AWT or Swing at least) is to asks a widget's current Font (actually a Font's FontMetrics), to calculate and return the width that will be necessary to display a given string in pixels. But how does one obtain a TextView's Font? I haven't found any method to obtain a (Text)View's font and/or calculate a more appropriate width given the actual content of a cell's text string. How does one do that in Android?
I'm building a text at runtime that will be put into a TextView. This text has composed with different size fonts. I must calculate the width in pixels of this text. I have tried to use Paint.measureText, but it does not consider the different font sizes.
How can I calculate the real width?
this is an example: code..
In this example, if I set the relative size to "2f " or "3f"(for example), the total size that returns "MeasureText" is the same.
Need a app that can do that... google earth for the pc gave good elevation based on where u placed your mouse on the map.... the map function unfortunately doesn't or if so... don't know how to access it
