[android-developers] Re: What is the approx time taken to register as a developer and to be able to publish apps on the Android Market?
True. Here is the answer that i got on the Android Market forums: Free apps: Typically less than 10mins. (Setup Checkout account to pay, fill android developer profile data). Paid apps: May take a couple of days. At times more. (Needs you to verify merchant account by receiving a few cents into your bank account). ADC2: Less than a minute. No need to register as an android developer in market. http://www.google.com/support/forum/p/Android+Market/thread?tid=5928797454f6e902hl=en On Aug 26, 10:03 am, Michael Leung michaelchi...@gmail.com wrote: That is the reason I think Android is more developer friendly.

[android-developers] Re: ADC 2 Submission Site -- Now live
This request might sound like one to extend deadline but it is actually only to extend the window which is shorter than the estimate announced. Though our apps are ready, some developers are not immediately available (not because they are holidaying) and this weekend happens to be a long weekend in the UK. Business submissions unfortunately may not happen at weekends. For contingency another week would be very useful.

[android-developers] Re: Java N00b Test Question
Hello
From the looks of that code it is expecting you to build all your
samples in a file called AllTests.java and then compile it. To me it
looks a little pointless, you would be better off just running your
code normally.
If you are new to both android, java and eclipse I would suggest you
start with the Hello World and Hello Views on the google page:
http://developer.android.com/guide/tutorials/hello-world.html
It will be a lot easier for you and give you a little tutorial on how
to set everything up.
Good luck!

Hi there,
I am brand new to both Java and Android, but I'm really interested in
Android development. Anyway, I'm trying to get going with TDD for the
platform. I found this in the API samples:
public class AllTests extends TestSuite {
public static Test suite() {
return new TestSuiteBuilder(AllTests.class)
.includeAllPackagesUnderHere()
.build();
}
}
I believe it's supposed to allow me to run all my tests, however, I
have a separate test file, and it's not being called or run when I run
the tests in Eclipse. Do I have to set up further config to have the
project find all my test files?
Thanks in advance.

[android-developers] Re: How to manage service lifecycle when device kills it due to low memory
Thanks for a very detailed and informative response! It's a polling alert for football/soccer matches (FotMob actually), so maybe it is important after all :-) As a user I want to know what is running in the background and polling frequently but I have noted that Scoreboard and other apps are not showing that they are running. To me this is not very friendly since I can't stop them from polling the server once I have started the program. And I have no idea if the polling is still active. We decided early on to inform the user when we poll and allow them to click the notification to stop the polling, so I guess we can use the setForeground safely :-) We are using the scheduling of alarm when the phone goes in sleep mode but as long as the phone is awake we are using a regular timer. I think I have enough information to keep my service running now, thanks again. -Christer --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Advice for speeding up my drawing
Hi, I am creating an app that show some histograms off your traveling speed in different time periods (histogram for the last minutte, histogram for the last 2 minuttes etc.) I would like to have an animation, and have discovered that drawing everything takes arround 300-400ms. wich is to long for making my animation smooth, the animation itself is quite simple (2 lines and 2 dots). What i draw every frame right now is 20 antialised strings, size 14, in average ~5chars 8 of these strings will change every second. 1 of the string will change with the animation (this will become 5 strings if there is time) the main part of the screen, the one showing the histogram data, consist of a lots of squares wich needs to be updated every second. (450 squares) the presentation is split into 5 frames in the same view (has to be same view as arrows in one frame might point into another frame) invalidating only a part off the screen makes almost no difference (it does becomas a bit faster, but i still execute all my drawing stuff). I have tried to add a flag wheter or not the main part is dirty, but if i don't draw it, it is cleared. I might be missing something here... One possibility could be to render all the mostly static stuff to a bitmap, and then simply draw the bitmap. that would mean 10 strings only had to rendered on orientation change. I think it would make sence since the slowest rutine is the one drawing all the text. (the following is a typical timing for the drawing rutines, accmulated). V/HMMULTIBAR( 352): 0 - Drawing time: 0 ms V/HMMULTIBAR( 352): 1 - Drawing time: 53 ms V/HMMULTIBAR( 352): 2 - Drawing time: 62 ms V/HMMULTIBAR( 352): 3 - Drawing time: 85 ms V/HMMULTIBAR( 352): 4 - Drawing time: 280 ms V/HMMULTIBAR( 352): 5 - Drawing time: 303 ms I would really appreciate comments about wheter or not offscreen rendering is the way to go, or if there is a simpler way. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Advice for speeding up my drawing
If you haven't tried already: 1. Replace the strings that get modified with char[]. Strings are immutable objects so changing one means memory allocation and leaking. 2. Also check the Allocation Tracker for memory leaking. 3. For the constant strings I would use Picture or some bitmap buffer mechanism to store the drawn text and then just place it on the Canvas without overhead.

[android-developers] Re: How to use the RotationMatrix, actually how to get it
You confuse me:
I thought a and b are float vectors - that is, vectors containing
actual numbers, not pointers (for example to a Float class). As such,
you can not .clone() them.
Did you use Float (with capital F) instead of float (with lower case
f)?
Floats are classes surrounding float.
If you want to work time-critical, you should use the simple float:
float[] a = new float[3];
float[] b = new float[3];
a[0] = 1.2f;
a[1] = 2.3f;
...
and NOT
Float[] a = new Float[3];
a[0] = new Float(1.2f);
a[1] = new Float(2.3f);

I admit to not having worked with Java enough to have the deep

ran into a problem trying to make a copy of an array and had to write
my own copy.
I had a set of data that gets consumed while the app runs. I wanted to
reset that data at times. I put the data in an array and then cloned
it to the working array. I was surprised when the original data got

How in Java do you actually make a deep copy of an array?

Did you use Float (with capital F) instead of float (with lower case

Floats are classes surrounding float.
If you want to work time-critical, you should use the simple float:
float[] a = new float[3];
float[] b = new float[3];
a[0] = 1.2f;
a[1] = 2.3f;

[android-developers] Re: Communication between Android devices over 3G
Thanks for the low latency :) You can use 3G for communication to another device on 3G. You have only to know that the IP address on 3G is NAT'd. You have to make sure that you tell the other device how to deal with the NAT traversal. One way to solve this is having an external server which is able to translate the IP addresses correctly. By external server, do you mean a server that lies outside the 3G network itself but is connected to it or a third-party server with static IP inside the 3G network itself (intuitively I'd go for the latter but I want to be sure). Also regarding this NAT issue, does the provider actually break the whole network into small cluster (like city-centric or something like that) and NAT is used between those or is it located somewhere else ? This question is more to see how NAT fits in the bigger picture. Sy. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: OpenGL ES confusion
Hi,
I'm not an OpenGL expert but I suspect that the confusion may be that
you are using the fixed point vertex arrays (passing GL_FIXED to
glVertexPointer for instance) to set up your vertex co-ordinates. This
is probably a good thing as it should be faster to use fixed point
rather than floating point on hardware that does not have floating
point acceleration but in the case of fixed point the numbers are
represented as a 32 bit int where the top 16 bits are the integer part
and the bottom 16 bits the fractional part.
Hence to set a value of 1 you actually need to use an integer value of
0x1 (ie 65536) for your vertex value.
Thus the values you need are apparently much larger than you were
expecting.
Take a look at the API demos cube.java to see what I mean.

[android-developers] Move focus to top of activity on create
Hi all, I have an activity that begins with almost a page of text, then has a few form controls. When the activity launches, the first form control takes focus and the screen scrolls down to make it fully visible. When this happens, the text at the top is off the top edge of the screen. When the screen comes into view, I want the text at the top to be visible. So, onCreate, I tried sending a message to the Activity's overridden handler to do the following: ScrollView main = (ScrollView) findViewById(R.id.main); main.pageScroll(ScrollView.FOCUS_UP); This did nothing. I then tried main.scrollTo(0,0); This also did nothing. I then tried sending the message from onResume instead of onCreate. This also did nothing. Does anyone have suggestions as to how to force the scrollview to actually scroll?

[android-developers] ProgressDialog on Oncreate method
Hi,
We are having some problems showing a ProgressDialog on a onCreate
method (for example, when the app calculates some operations before
starts).
This is a example of what is our problem:
public class dialog extends Activity {
/** Called when the activity is first created. */
int res;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TextView tv = (TextView) findViewByID(R.layout.textv);
final ProgressDialog pd = ProgressDialog.show(this, Title,
Message,
true, false);
new Thread(new Runnable() {
public void run() {
try {
res = 2+2;
Thread.sleep(1000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
pd.dismiss();
}
}).start();
tv.setText(res);
}
}
We cant do the tv.setText in the thread because it throws an
Exception. The problem is the dialog doenst appear until the Thread is
finished,
Any help?

[android-developers] LocationManager always returns null ... ?
Hi,
Below is a short script I wrote to obtain the location of the phone using the
embedded GPS device.
...
LocationManager locationManager;
locationManager =
(LocationManager)getSystemService(Context.LOCATION_SERVICE);
Location location =
locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
updateWithNewLocation(location);
}
private void updateWithNewLocation(Location location)
{
TextView myLocation;
myLocation = (TextView)findViewById(R.id.myLocation);
if (location != null)
{
double lat = location.getLatitude();
double lng = location.getLongitude();
myLocation.setText(My Current Position is \n Lat: +lat+\n Long:+lng
);
} else
{
myLocation.setText(My Location Could NOT Be Found);
}
}
...
I have all the permits in the Manifest file at the right places:
uses-permission android:name=android.permission.ACCESS_FINE_LOCATION /
uses-permission android:name=android.permission.ACCESS_COARSE_LOCATION /
uses-permission android:name=android.permission.ACCESS_MOCK_LOCATION /
uses-permission android:name=android.permission.INTERNET /
(PS. I know that I don't need COARSE_LOCATION and INTERNET access in this
particular case)
Anyway, the code seems to work fine, but locationManager always returns null
even though I tried to send mock location data to the Android Emulator via the
DDMS application using the Manual Location tab. Whatever I send seems to be
ignored. I also tried establishing a telnet connecton to the emulator and using
the command geo fix lat long. I did get an OK message yet, the emulator still
returns null to my request.
Any ideas about what might be the problem ?
Cheers,
Emre

[android-developers] Re: How to manage service lifecycle when device kills it due to low memory
You really should be using an alarm to start your service and then stop it when done. If you are polling often enough (like less than every 5 minute or so) that this doesn't make sense, then you are going to kill the user's battery. On Wed, Aug 26, 2009 at 2:10 AM, cnordvik cnord...@gmail.com wrote: Thanks for a very detailed and informative response! It's a polling alert for football/soccer matches (FotMob actually), so maybe it is important after all :-) As a user I want to know what is running in the background and polling frequently but I have noted that Scoreboard and other apps are not showing that they are running. To me this is not very friendly since I can't stop them from polling the server once I have started the program. And I have no idea if the polling is still active. We decided early on to inform the user when we poll and allow them to click the notification to stop the polling, so I guess we can use the setForeground safely :-) We are using the scheduling of alarm when the phone goes in sleep mode but as long as the phone is awake we are using a regular timer.

[android-developers] Re: Communication between Android devices over 3G
With external server I refer to a server which is public reachable somewhere in the internet. For example for doing some Voip stuff you would place a public reachable PBx in the internet. This server would know how to translate addresses correctly (see Asterisk PBx which has built in functionality to handle NAT). On Aug 26, 5:41 am, Sew seweryn.dynerow...@gmail.com wrote: Thanks for the low latency :) You can use 3G for communication to another device on 3G. You have only to know that the IP address on 3G is NAT'd. You have to make sure that you tell the other device how to deal with the NAT traversal. One way to solve this is having an external server which is able to translate the IP addresses correctly. By external server, do you mean a server that lies outside the 3G network itself but is connected to it or a third-party server with static IP inside the 3G network itself (intuitively I'd go for the latter but I want to be sure). Also regarding this NAT issue, does the provider actually break the whole network into small cluster (like city-centric or something like that) and NAT is used between those or is it located somewhere else ? This question is more to see how NAT fits in the bigger picture. When you are connected to the 2G/3G network you will get a IP address on your device which is NOT public reachable. This IP address is mapped to a public reachable IP address. Reason for doing this is because IP addresses are limited resources. You can find out about your public IP address when you start the browser and go to the web page http://www.whatismyip.com/. Normally the 2g/3g covers a big area which goes over the boundaries of cells. When your drive in the car the chances are very slim that you get a new IP address assigned because you are roaming. -- Roman Baumgaertner Sr. SW Engineer-OSDC ·T· · ·Mobile· stick together The views, opinions and statements in this email are those of the author solely in their individual capacity, and do not necessarily represent those of T-Mobile USA, Inc.

[android-developers] Changing a color in a Drawable
I tried asking on the android-beginners list and had no luck, so I thought I'd try here. I'm working on an android application, and I have a drawable that I'm loading up from a source image. On this image, I'd like to convert all of the white pixels to a different color, say blue, and then cache the resultant Drawable object so I can use it later. So for example say I have a 20x20 PNG file that has a white circle in the middle, and that everything outside the circle is transparent. What's the best way to turn that white circle blue and cache the results? Does the answer change if I want to use that source image to create several new Drawables (say blue, red, green, orange, etc)? I'm guessing that I'll want to use a ColorMatrix in some way, but I'm not sure how.

i encrypt the file on 1st run and on 2nd run i check if file is
there
then decrypt and show.
so only thing i understand is to store the key somewhere in the app
so
i can access it for decryption.
just wondering if this help
File keyFile = new File(data/data/package name/key);
i followed this link for encryption and decryption

[android-developers] Re: MyTouch Lag Problems
Getting the output of adb bugreport is very valuable for diagnosing an ANR -- it will have all stacks of all apps running (including the main thread of the foreground app that had the ANR), in the log there will be cpu information at the time of the ANR, etc. Of course the output of this command is something like 1MB; if you want something smaller, these are probably the key things to get: adb logcat adb cat /data/anr/traces.txt adb procrank adb shell dumpsys activity On Wed, Aug 26, 2009 at 8:59 AM, Mike michaeldouglaskra...@gmail.comwrote: Thanks for taking the time to download the game and try it out on your hardware.

[android-developers] Re: LocationManager always returns null ... ?
Anyway, the code seems to work fine, but locationManager always returns null even though I tried to send mock location data to the Android Emulator via the DDMS application using the Manual Location tab. Whatever I send seems to be ignored. I also tried establishing a telnet connecton to the emulator and using the command geo fix lat long. I did get an OK message yet, the emulator still returns null to my request. Any ideas about what might be the problem ? Use requestLocationUpdates(). Unless your timing is perfect, you will not be able to send the fix at the right time for getLastKnownLocation() to work as you expect. Moreover, on a production device, getLastKnownLocation() will *never* work as you expect, because it takes GPS several seconds, at best, to get a fix, and it will only *try* get a fix because you have called requestLocationUpdates(). -- Mark Murphy (a Commons Guy) http://commonsware.com Android App Developer Books: http://commonsware.com/books.html --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Error : Unknown URI: content://media/external/images/media
I think this is the problem:
Uri uri = getContentResolver().insert(Media.EXTERNAL_CONTENT_URI,
values);
The first parameter of 'insert' must either be a bitmap or the path to
an actual image-file. Right now, you provide the value
Media.EXTERNAL_CONTENT_URI, which is a directory, not a file.
E.g., i think this would work ok:
Bitmap sourceBitmap = BitmapFactory.decodeResource(getResources(),
R.drawable.test);
Uri uri = getContentResolver().insert(sourceBitmap, values);
Or
First create an empty file in the directory Media.EXTERNAL_CONTENT_URI
and provide the full path of this file for the insert method.

[android-developers] MediaRecorder setVideoFrameRate
Hello Android developers, I am experimenting with video capture/encoding using the MediaRecorder class. One thing I noticed during testing is that it seems like the setVideoFrameRate method of the MediaRecorder class has no effect. In other words, the MediaRecorder does not seem to adhere to the frame rate I set for it. Using a target frame rate of 5 FPS results in a video fragment that is equally fluid/smooth as one created at 15 FPS. I am using a HTC Magic device. My MediaRecorder code is as follows (excluding exception handling): MediaRecorder mMediaRecorder = new MediaRecorder(); mMediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA); mMediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP); mMediaRecorder.setVideoSize(176, 144); // QCIF mMediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.H263); mMediaRecorder.setVideoFrameRate(5); mMediaRecorder.setOutputFile(/sdcard/maarten.3gpp); mMediaRecorder.setPreviewDisplay(previewSurface); mMediaRecorder.prepare(); mMediaRecorder.start(); ... mMediaRecorder.stop(); mMediaRecorder.release(); Pretty straightforward code. Has anyone experienced something similar? Has any of you been able to successfully enforce an actual frame rate on the MediaRecorder?

I want to provide buttons in my app that appear/disappear near the bottom of the screen on touch near the bottom similar to how the browser zoom magnifying glasses appear and disappear. Is there an api to do this? TIA Jay --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: how and where to save SecretKey for encryption and decryption
The more important question I think is why are you doing this, what information are you trying to protect? It seems like you're adding encryption for the sake of it, but in fact your solution won't be much more secure against someone determined to get at the file's contents. If the key is static, then it is easier to break, but if it changes then it would need to be stored, making it easier to access. One alternative is to generate the secret-key using a sufficiently hard to guess algorithm, using some information about the device, so that the key used is very different for every user, reducing the change of simple comparisons being able to break your encryption. However, someone clever could still probably figure out how your encryption works by examining the Java byte-code, as while it's tough to get your head around it's not impossible to understand. Perhaps in your case the effort required to break the encryption might be more than it's worth to get into the file, but if you let us know what kind of information you're hoping to store, then perhaps we can give you some better solutions? If it's something dangerous, like payment details or something, then you need the most rock-solid solution possible, but if it's something minor then encryption may be a waste of time entirely.

But better to jus have a constant field in ur class that cointains ur key. SecretKey key = KeyGenerator.getInstance(DES).generateKey(); byte[] keybytes = key.getEncoded(); String keyString = new String(keybytes); If u r gonna execute these set of statements then wont the key change?? or plz provide any example for the best practice On Aug 26, 12:28 pm, Sujay Krishna Suresh sujay.coold...@gmail.com wrote: If it is only used by ur application, jus use a String instance to hold the key. y store in a file?? ll the key change dynamically???

[android-developers] Re: java question
I think this is a valid Android question, as Android might handle this differently than standard JavaSE. Specifically, JavaSE lets you do this and (to the best of my knowledge) Android does not.
