[android-developers] Re: Varied accelerometer sample rate
You might try writing your data to the LogCat and then capturing it
from there. Writing to a file might be introducing some of the delays
your are seeing.
Another option is to just write to LogCat when the time between
samples exceeds a certain amount.
I've seen file and other I/O impact results on other resource limited
systems when trying to capture real-time data. At least eliminate that
possibility before proceeding.

[android-developers] Re: sensor event and augmented reality
I did some testing on the compass direction and the results are, eh, interesting. I compared the readings I was getting with the Google Sky Map and they were basically the same. Here is what I did. With both my app and SkyMap I had the phone in camera position. I positioned the phone on a piece of paper and drew a line on along the side in contact with the paper. I did this for N, E, W, & S. As I said, the lines from my app agreed with the ones from Sky Map. I drew a N/S line using a physical compass. The lines for N & S were rotated a bit clockwise from being right angles to the N/S line. The E/ W lines were both skewed even more clockwise from the N/S line. [Yeah, I've calibrated the phone doing figure 8's and flipping it while rotating it, etc.] It also appears that the sensors expect the phone to be in camera position, i.e. left side down, because when the right side is down all the compass points are even worse. I'd be curious to see if other phones get similar results.

[android-developers] How to measuring elapsed time without currentTimeMillis?
Hi, I want to develop a game, so I need to know elapsed time at lots places in my game. For example, to measuring FPS. I see there is some example use "System.currentTimeMillis" to measure elapsed time. But I see the warning on document: http://developer.android.com/intl/zh-TW/reference/java/lang/System.html#currentTimeMillis%28%29 "This method shouldn't be used for measuring timeouts or other elapsed time measurements, as changing the system time can affect the results." So, if this method should not be used for measuring elapsed time, then what will be suitable? Thanks.

[android-developers] Lazy-load images into a ListView
Hey all, I will be surprised if this hasn't been asked before, but I've been Googling for days now and haven't found anything very helpful. My problem is this: I'm trying to lazy-load images into a ListView--almost exactly how Market does it, if you're familiar with that. It's not exactly like Market because the images there comes in batches whereas mine are one at a time, but I digress... I have the following adapter: http://paste2.org/p/318634 This adapter lazy-loads pages and each row's corresponding image (if applicable) and caches it to disk for faster loading next time. This all works perfectly *except* when loading images over the network, they come in on the wrong rows and are sometimes duplicated. I assume that this has to do with the adapter reusing views, but I haven't been able to stamp it out. Thanks for any help or pointers you can provide.

[android-developers] Re: sensor event and augmented reality
I've been looking at all of this the last couple days.
I have an application that puts the three numeric values on the
display. The code is below and I _think_ it is working okay.
My test is to hold the phone against a wooden(!) door so I have a
nearly vertical, steady surface. Say I put the back of the phone
against the wall. I then rotate it through 360 degrees. The bearing
(compass reading - (outR[0])) remains steady. The third value (value
[2]) rotates through 0 to 180, -180 to -1. If I put the end of the
phone against the door the second value (value[1]) rotates through 0
(right side pointing up) to 80 (laying flat, screen up) to 0 (left
side up) to -80 (-81) when upside down. {It goes 0 to 80 to 0 to -80
to -1, in short).
So basically the numbers look good for determing the position on a
sphere similar to that used in the Google SkyMap application. I
haven't looked at the scaling etc. The only conversion, as you see, is
from raidians to degrees. This is my first result that looked
approximetly correct so there maybe some fine adjustments needed on
conversions, etc and the code needs clean up.
I'm doing the calculation only after receiving an update from the
accelerometer, skipping the magnetic update. I figured doing it each
time was to fast.
Hope this helps. I now need to determine if the three results do
actually give the spherical position. I don't think it is given
directly but needs to be interpolated. Once I get it figured out I'll
put it on my blog.
A word of caution - being near a computer or monitor can distort the
magnetic field. As can being by a metal door. Make sure you are away
from these when testing.
Any comments appreciated.

[android-developers] Re: "Complete Action Using" dialog
It's not actually a dialog. PackageManagerService returns the information for a special activity when resolveIntentActivity() finds multiple matching activities. So that code does the detection, and the component it returns is the one that ends up getting launched and displays the list of matching activities.

If you are trying to get fancier with your ListViews, I have an excerpt from one of my books that discusses that process: http://commonsware.com/Android/excerpt.pdf with sample code available from: http://commonsware.com/Android In a nutshell, you create an Adapter object that maps from raw data (e.g., an array of strings) to Views that go in each row (e.g., a TextView). How simple or complex that process is depends on how fancy the rows are.

[android-developers] Modifying the UI within Java, not XML
So I have the basics down... I can create a UI with the XML, I can show it and change the screen to another UI (another XML file) but how do I add to the UI? Hmmm, hard to explain... Say I have a header (just 2 textviews) that will remain at the top and below that is a search box and button (main.xml). The user searches and I have it display the search UI (search.xml). This UI will have the same header (2 textviews) and below it will have several textviews each one containing a search result... Kinda like if you search for an app in the market. There's no way of telling how many results would be returned so I figured I would have to create each textview on the fly within the .java file. I'm not sure how to do this. Most likely would require a loop of some sort, but whats the syntax to create a new textview and display it right below the one above it? I'm working with linear here so I would assume just creating a new textview it will by default go to the next one down which is what I want. Any help? I searched a lot but I'm not sure what it's called that I'm looking for exactly. Also, say I have 30 results... How do I get those to scroll but leave the 2 textview header in place? Would I create a ScrollView and put the new TextViews in that? I'm probably way off here, but any correcting is fine.

[android-developers] Re: How to Handle Multiple Adapters for one ListView
The alternative would be, if I understand your question correctly, to have one listadapter that takes data from various sources, depending on some variable that is set. Your app would prepare the various sources of data independently, and the getView in your listadapter determines which of the sources is used at what time. I think that would be less complex than having a number of list adapters on one listview in one Activity. But again, I may misinterpret your question.

Try Iterator instead of just Iterator. The code will run
just fine in this case, but you lose any compile-time type-safety checks
for down the road (e.g., you accidentally try assigning an
Iterator instead of an Iterator).

In this code: (which works fine)

Iterable iSatellites = xGpsStatus.getSatellites() ;
Iterator it = iSatellites.iterator() ;

there is a warning error on this line:
Iterator it = iSatellites.iterator() ;
"Iterator is a raw type. References to generic type Iterator should

although the code runs as expected. Is this an important error or

Apparently it's not such a good idea. As of now, if this matters anyways, my fatty Activity uses at most 70% of the given 3.9MB Heap size.

Moto wrote: > Currently my lists can contain max 60 items and the > elements are fairly complex, about 5 TextViews no backgrounds. > > So multiple ListViews is not good for one activity? "Good" versus "not good" is a binary statement. In reality, it is more a continuum of increasing "not good" as you increase the number of ListViews, the number of rows in those ListViews, and the number of widgets per row (TextViews, layouts, etc.) that you wind up holding onto to achieve your desired effects. The "fatter" your activity becomes, the more likely it is that it will be "not good" in the eyes of users, because: -- It crashes due to out of memory errors, perhaps on lower-end handsets that come with less RAM for applications -- It kicks too many other applications out of memory when it runs -- It generates so much garbage that the garbage collector slows down whatever application they run next (e.g., a game or video that cannot keep up the frame rate) -- It winds up being killed off forcibly, rather than gracefully shut down and saving its state, because it uses up too much memory and Android needs that memory quickly to handle some incoming phone call or text message or something -- And so on Whether your app meets any of those criteria is impossible to say based on a set of emails -- only you and your users will be able to tell. So, while I am convinced that several thin, cheap activities are better than one fat, expensive activity that performs all the same functions, that is just a rule of thumb. Only you and your users have the application and can determine if, indeed, you are using more memory than is wise. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy Need Android talent?

[android-developers] Re: How to Handle Multiple Adapters for one ListView
Hey Mark, Let me explain a little better the situation: I only have one ListView and I'm displaying only one list at a time. The reason that I'm doing all this work inside one activity is that it gives me better flexibility when animating. If I could animate activities in and out on top of my graphics would definitely be worth looking into. Currently my lists can contain max 60 items and the elements are fairly complex, about 5 TextViews no backgrounds. So multiple ListViews is not good for one activity? Thanks Mark..

[android-developers] Re: problem in receiving the status of call
The activity you specified is not present on the device that you ran
your app on.
You generally shouldn't explicitly name activities like that. You
should use a 'send' or 'share' intent, and the system will figure out
which activities support it.

[android-developers] Re: Speech Recognition
I'm unclear about the availability of the voice recognition service. I tried the above example on my Vodafone branded HTC Magic (API version 1.5) but it's "Recognizer not present". There seems to be no application in the Android Market that provides this service (unlike Text To Speech functionality which is installed by downloading an application). Any suggestions? Do I have to wait for the next major firmware update? Thanks, Joe. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] GpsStatus
How can I derive the getMaxSatellites(), getSatellites() and
getTimeToFirstFix() from the GpsStatus Listener?
-John Coryat
I've got the listener for GpsStatus working like this:
LocationManager locMgr = (LocationManager)getSystemService
(Context.LOCATION_SERVICE);
locMgr.addGpsStatusListener(onGpsStatusChange) ;
// Listener for GPS Status...
private final Listener onGpsStatusChange=new GpsStatus.Listener()
{
public void onGpsStatusChanged(int event)
{
switch( event )
{
case GpsStatus.GPS_EVENT_STARTED:
// Started...
break ;
case GpsStatus.GPS_EVENT_FIRST_FIX:
// First Fix...
break ;
case GpsStatus.GPS_EVENT_STOPPED:
// Stopped...
break ;
}
}
} ;
Thanks...

[android-developers] Re: Where to find native resources?
This is where one can find a lot of the native drawables http://developer.android.com/reference/android/R.drawable.html I've been informed to use in xml @android:drawable/ic_menu_camera to get the camera icon. It's not the big blue camera icon one would see in the home screen though. It'd be better if Google could show the images corresponding to the different annotations so we don't have to guess what they represent. Can someone please tell me how to access the shutter sound?

[android-developers] Hiding Soft input like using BACK buton
Hello, In my app I have AutoCompleteTextView and "search" button. When user clicks "enter" or "search" an Intent is fired and new Activity is started. But in that "new" Activity SoftInput should be invisible, so I make ((InputMethodManager)getSystemService (INPUT_METHOD_SERVICE)).hideSoftInputFromWindow(this.getCurrentFocus ().getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS); But when user clicks BACK and returns to activity with form he is unable to show soft input back by touching AutoCompleteTextView. He mus use trackball to select "search" button and than touch ACTextView. Bud when he is in "form" activity first time, shows soft input by touching AutoCompleteTextView and presses BACK button he is able to show soft Input by touching field. How can I hide soft input "correctly" (so it can be shwed back in intuitive way?) or hide it like BACK button does?

[android-developers] Re: Memory leak in AudioTrack?
I now ran into the very same problem on my ADP phone as well after
applying settings for more strict JNI checking: by default, JNI
checking is active on the emulator but not on the phone, so that is
why I did not readily see it on the phone until activating JNI
checking there for unrelated reasons. I have now filed a bug report at
http://code.google.com/p/android/issues/detail?id=3234

[android-developers] HTC Magic vs G1 performance
I find that my ADP1 phone has a better performance than my Google IO phone. In some cases, the Magic gets a timeout error where the G1 doesn't, running the same software. Also, I've seen a situation where a service would accidentally take too much resources, which the Magic couldn't handle - the screen would freeze - while the G1 could. The phones have identiical sim cards from the same provider. This means I use my IO phone for testing, mostly :-) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
