[android-developers] Re: How to know a view size before it's rendered
Hi, I find really hard to imagine that there's no way to know the actual Views' size before they are displayed. I was expecting a sort of callback method on the Activity class or any listener on the View (or ViewGroup) to be implemeted so that I can get the size of UI components. Anyway, I found a sort of workaround which in the onCreate method of an Activity, I'll get a reference to the Display object thorugh the WindowManager display = this.getWindowManager().getDefaultDisplay(); Once I got the display, I can get the width and height of it and with that I can tweak some settings of some animations I want to apply on some UI components. Ideally, a callback method on the Activity which allows to know the actual size of UI components just before they are displayed would be preferred.

[android-developers] 'Squeezing' a button on the right side
Hi, you probably heard similar problems before but i can't figure out how to do this programatically. I have a vertical layout with FILL_PARENT on both dimensions. In it i have multiple horizontal layouts with FILL_PARENT width and WRAP_CONTENT height. In each of these horizontal layouts i want to put a checkbox on the left and an ImageButton on the right. The problem is i can't stop the checkbox from growing to the point of pushing the ImageButton out of view.. (same thing happens when the checkbox has FILL_PARENT or WRAP_CONTENT widths). For individual stuff i managed to do it in the XML layout very easily: ...something... android:layout_width=fill_parent android:layout_height=wrap_content android:layout_weight=1 / ...something... android:layout_width=wrap_content android:layout_height=wrap_content / Same thing doesn't work programatically though, and i've tried other gravity, weight, layout combinations..

[android-developers] WiFi data transfer stalls as soon as screen becomes blank
Hello everyone, I am currently trying to figure out how to fix an annoying bug in Sipdroid [1], which seems to be triggered by a power management optimization in Android 2.1: While a SIP (VoIP) call is in progress via WiFi, the data transfer becomes unreliable (and basically stalls) as soon as the display goes blank after the display timeout or proximity sensor has been triggered. As soon as the display comes back (by hitting the power button or releasing the proximity sensor) the data transfer reverts back to normal. Currently, the only possible workaround seems to be to acquire a PowerManager.SCREEN_DIM_WAKE_LOCK for the duration of the call, which reliably prevents the issue from surfacing. Still, I think it would be beneficial to come up with a solution that allows the screen to become blank (if only for reducing battery consumption). I already tried getting a WifiManager.WIFI_MODE_FULL to no avail. Any hint how to sort this out is much appreciated!

[android-developers] Re: Steps to transfer a simple object from server to android using XML
Hi raqz, I saw your previous post in that you were sending lists of friends via serialization and were advised to use xml instead. Instead of XML you could also use JSON as it is more lightweight than using XML and doesn't take long to implement. I was using XML as my back end for my database to communicate with my application but I changed it all to JSON and haven't looked back since. Here is an article on parsing JSON with Java http://www.androidcompetencycenter.com/2009/10/json-parsing-in-android/ Read through that and it should give you some ideas. There is an article on getting JSON back from the server but I can't find that at moment. Will try and dig it out though.

[android-developers] Thread always seem to throw exceptions although no erros in program
Hello,
I use a thread for drawing to the canvas. By coincidence I recognized
that in the program always jumps into the finally part. After
view.onDraw(c); is reached it steps back to synchronized
(surfaceHolder) and then it steps into the finally part. This happens
every time. This means to me that every time exceptions are thrown.
Can anybody explain why this is so?
public class GameThread extends Thread {
private SurfaceHolder surfaceHolder;
private boolean isRunning = false;
private GameView view;
private long tickFrequency;
private long lastTick = System.currentTimeMillis();
private int framesPerSecond = 25;
public GameThread(SurfaceHolder surfaceHolder, Context context,
Handler handler, GameView view) {
this.surfaceHolder = surfaceHolder;
this.view = view;
tickFrequency = 1000 / framesPerSecond;
}
//Speed should be 25 frames per second
//1 Frame per 40 ms
@Override
public void run() {
Canvas c;
while (isRunning) {
c = null;
//updatePhysics();
if (System.currentTimeMillis() lastTick + tickFrequency) {
long timeDiff = System.currentTimeMillis() - (lastTick +
tickFrequency);
try {
c = surfaceHolder.lockCanvas(null);
synchronized (surfaceHolder) {
view.onDraw(c);
}
} finally { //do this in a finally so that if an
exception is
thrown during the above we don't leave the
if (c != null) { //surface in an
inconsistent state
surfaceHolder.unlockCanvasAndPost(c);
}
}
lastTick = System.currentTimeMillis() - timeDiff;
}
}
}

isRunning = run;

[android-developers] Re: Internal links in Webview
Hi, Just to interject. Mark explains this beautifully in his book 'Beginning Android', but even more in his PDF books and it is what I use for my details page for items in my database. Basically I have a front activity that shows a search box, that then populates a listview with the headers. The user then clicks a header and the details are retrieved from the database and parsed into a WebView on a separate activity. Inside this WebView I have 'internal' links that allow me to retrieve yet more information that the user might want to know. I do it this way so it doesn't put unnecessary strain on both my database and the users phone. His books are amazing for learning all the nuances of the Android system, so much so I've only had to ask here once about a problem I was having, but that was my mistake lol. Kudos to Mark.

[android-developers] Re: Thread always seem to throw exceptions although no erros in program
Hi,
A bit of misunderstanding on your part about the try-catch-finally :)
Finally is where you put code you want to execute no matter what
happened before, exception or not.
Catch is the code executed only when an exception occurs
Try is what you want to execute but might trigger an exception.
See java :

[android-developers] Out of memory and no useful stack trace
My android app is getting an Out of memory error without a useful stack trace. It occurs after I have repeatedly re-invoked its main logic through a menu interaction, which leads me to believe that there's a memory leak somewhere. I say that the stack trace isn't useful because it doesn't include references to any of my own code. There are no references to my own code in the logcat output, either. I'm wondering if any of you can help me figure out where my memory leak might be occurring, given my stack trace and my logcat output. Here's the stack trace: Thread [3 main] (Suspended (exception OutOfMemoryError)) ViewRoot.handleMessage(Message) line: 1716 ViewRoot(Handler).dispatchMessage(Message) line: 99 Looper.loop() line: 123 ActivityThread.main(String[]) line: 4203 Method.invokeNative(Object, Object[], Class, Class[], Class, int, boolean) line: not available [native method] Method.invoke(Object, Object...) line: 521 ZygoteInit$MethodAndArgsCaller.run() line: 791 ZygoteInit.main(String[]) line: 549 NativeStart.main(String[]) line: not available [native method] ... and here's the logcat output: [ ... lots of repetitions of the following WARN messages as I repeatedly invoke my app's main logic via a menu selection ... ] 04-11 09:27:35.341: WARN/InputManagerService(52): Window already focused, ignoring focus gain of: com.android.internal.view.iinputmethodclient$stub$pr...@4398a268 04-11 09:27:35.842: WARN/KeyCharacterMap(5262): No keyboard for id 0 04-11 09:27:35.852: WARN/KeyCharacterMap(5262): Using default keymap: / system/usr/keychars/qwerty.kcm.bin 04-11 09:27:36.852: WARN/InputManagerService(52): Window already focused, ignoring focus gain of: com.android.internal.view.iinputmethodclient$stub$pr...@439c3f38 04-11 09:27:38.782: WARN/InputManagerService(52): Window already focused, ignoring focus gain of: com.android.internal.view.iinputmethodclient$stub$pr...@43909130 04-11 09:27:39.392: WARN/KeyCharacterMap(5262): No keyboard for id 0 04-11 09:27:39.392: WARN/KeyCharacterMap(5262): Using default keymap: / system/usr/keychars/qwerty.kcm.bin 04-11 09:27:40.332: WARN/InputManagerService(52): Window already focused, ignoring focus gain of: com.android.internal.view.iinputmethodclient$stub$pr...@43996c88 04-11 09:27:41.931: ERROR/dalvikvm-heap(5262): 345600-byte external allocation too large for this process. 04-11 09:27:41.931: ERROR/(5262): VM won't let us allocate 345600 bytes Could my error be related to the Window already focused ... warnings?

[android-developers] Re: Service vs Singleton
An Android application (APK) may consist of more than one Activity, more than one Service. Each Activity or Service can run in its own process, can share a process or are run in the process of the calling Activity (and the calling Activity may not even be part of your application: e.g. the Contact app asking the Gallery app for a picture). You can define your app's (APK's) manifest file to have certain activities/services run in their own processes or to just share the process of any calling activity. The process here is a process running on the Linux kernel. On Apr 10, 10:25 pm, Jason LeBlanc jasonalebl...@gmail.com wrote: Since process != application.. just what are the distinctions? On Fri, Apr 9, 2010 at 5:06 PM, Bob Kerns r...@acm.org wrote: Just to point out a couple more things here. 1) a Service's lifetime is NOT, in general, the same as an Application's lifetime. A service can be deleted when it's not in active use by any activity or intent. This can save memory. 2) Under some circumstances, more than one application may be running in the same process. You won't be encountering those situations by accident, but it's an important part of the model nonetheless. In Android, process != application. 3) By using a service, you get control over when and how your service gets restarted if your application and process get deleted in a low- memory situation. Services will be automatically restarted. Applications, and any singletons they manage, will not, unless they're required by a service being restarted! In a sense, your service continues to exist even when there's no process available to run it in.Once a process is available, your service is recreated and resumed. (This applies to services started with startService rather than binding. But if you want this, you can do both operations on the same service).

[android-developers] Progress Bar in every row of ListView
Hi, I am trying to have a progress bar in every row of my list view. My list is an iconic list view and have implemented it in the lazy loading way..so i want to display a progress bar (spinning progress bar) till the images are not loaded. My current approach is that i hv placed the progress bar in the layout and in my code in the getView method i dismiss it when the image is loaded. However this seems to work properly only for the first row of the list view. The progress bars are visible on the rest of the rows even if the image is loaded and only when i scroll the list do the progress bars disappear so i am assuming this is something to do with refreshing the list view. So I have tried using notifyDataSetChanged in my getView but it is not helping. Please can anyone let me know if they have worked on anything similar to this.

[android-developers] Is SignalStrength readable outside onSignalStrengthschanged?
With SDK 2.1 it is possible to get some additional signalstrength information in the Phonestatelisteners onSignalStrengthsChanged event. That works, but I need to monitor the signalstrength more accurate. onSignalStrengthsCanged is only fired if one of the four signal bars of the signalstrength indicator have changed. So I tried this outside: SignalStrength sig new SignalStrength(); rxl = sig.getGsmSignalStrength(); But it tells me that SignalStrength() is not visible. Why is that? The funny thing is, that the NeighbouringCellInfo gives me the Signalstrength of the neighbourcells every second, if I want. But the serving cell is updated very badly. Also I can use getGsmBitErrorRate() only in onSignalStrengthsChanged. That makes no sense, because the quality of the signal is largely independent of the strength. So is there a change of getting the actual signalstrenth outside onSignalStrengthsChanged? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Generating a static HashMap from resources?
In my app, I'd like to define some static resources in an xml file
which can be accessed via a HashMap. I know I can do this at run time
in a manner similar to the one which is described here:
http://groups.google.com/group/android-developers/browse_thread/thread/6232ee60944890e8/895415654ccbc21f?lnk=gstq=hashmap+resources#msg_895415654ccbc21f
However, since my HashMap will be a non-changing resource, I'd like to
precompile my xml into a static HashMap in a manner that is similar to
how the aapt utility precomplies the data in various xml files into
R.java. Furthermore, I'd like the keys and values to be expandable via
the @+id/item convention, as follows ...
Suppose the following items exist in strings.xml:
string name=string0foo/string
string name=string1bar/string
string name=string2quack/string
string name=string3oink/string
Then, I would like to be able to do something like this in order to
specify my static HashMap:
?xml version=1.0 encoding=utf-8?
map name=mymap
element name=@+id/string0foo-item/element
element name=abc@+id/string1/element
element name=@+id/string2@+id/string3/element
/map
The resulting generated code in R.java would look something like this:
public static final class map {
public static final MapString , String mymap = new
ConcurrentHashMapString , String() {{
put(foo, foo-item);
put(abc, bar);
put(quack, oink);
}};
}
Is there a way to do anything even remotely similar to this under
Android, perhaps using aadb?
Or am I out of luck?
Thanks in advance.

[android-developers] Re: Android OpenGL Game - App Architecture and Threading Logic
You say: So, say I have the game loop logic in a thread like that,
using the
render fps average as a counter, I've noticed that the fps drops when
using more than one thread, even if it's just running in an empty
loop.
Um, ESPECIALLY if it's running in an empty loop. The point is, you
don't want it to run AT ALL unless it has something to do.
Handler is one way to do this. Sleep never helps you do this, UNLESS
something to do is purely based on time.
What your code below is doing is called polling. Polling is the
technique of last resort, because your thread has to wake up
periodically even if there's nothing to do.
That may not be serious -- and sometimes it's your only choice. But
the ideal is to block, waiting to be told there's actual work to do.
I remember timing this was I would constantly send network data to
the
network thread with a timestamp, then I would check how long it took
for that message to make it to the game loop by determining the time
difference.
This doesn't sound like a good way to measure, as there are too many
variables.
If you created the timestamp at the point of sending it to the
handler, and how long it took before the handler began executing,
you'd have a valid measurement of the latency. However, even latency
is not telling you efficiency.
Using a Handler does not involve creating a thread, so I'm not sure
why you mention that you use a thread pool. Indeed, if you're using
multiple threads to do intermittent work, a thread pool is a good
idea. However, since you have only one main processor, if you're doing
work that doesn't block, you may find no advantage, and even a small
performance DECREASE, by having more than one thread in your pool!
(There can be other reasons to have more than one thread, however; I'm
just discussing performance).
Handler is presumably doing something like this to queue:
synchronized (m_actions) {
m_actions.add(r);
m_actions.notify();
}
And something like this to pull from the queue and execute:
while (true) {
Runnable action = null;
synchronized (m_actions) {
while (m_actions.isEmpty()) {
try {
m_actions.wait();
} catch (InterruptedException e) {
}
}
action = m_actions.remove();
}
action.run();
}
When there's nothing to do, the thread is waiting in the wait() call,
not running, not consuming any CPU. (It does consume some significant
memory; idle threads are not free!)
(Don't worry about that inner loop and catch of InterruptedException
-- nobody will be interrupting, that's a holdover from the early days
of Java).
When something is placed in m_actions, the thread running the loop
*immediately* becomes runnable. Whether it runs immediately depends on
whether it has to compete with other threads which are also runnable.
And more importantly, if it was NOT in the wait() call -- that is, it
is still running an earlier request, then it will not run the new
runnable until the old one completes, and it goes around the loop
again to check.
This loop NEVER runs unless there is work to do -- yet it's
immediately runnable when there is. (The exception is that it checks
if something is already queued on first entry). This is the ideal.
With polling, you have to check if there's work to do. The check here
IS run before waiting after just completing work, but the thread was
already awake in this case. It never wakes up just to see if there's
work.
The game loop I'm using is SUPPOSED to be 60fps but will undoubtedly
vary, I use the Timer class's scheduleAtFixedRate to automatically
take care of the timestep adjustments/wait time.
Since the timer class uses a thread pool, it doesn't have an overhead
of thread creation. I don't have to handle calculating how long to
sleep to maintain a constant rate, and is quite efficient.
I've achieved a smooth display, and the physics progresses a step at
each game loop iteration.
This has worked well for me.
If that's all worked well for you, I'm NOT telling you that you need
to change it. However, there's a number of ways this can break down
when you really push the limits.
But a guiding principle is -- Do The Simplest Thing That Could
Possibly Work. It sounds like you've achieved that, for now. Or maybe
The First Thing That Worked, and sometimes that's a good choice,
too! :=)
If someday you find it no longer meeting your needs, you can take
these other things into consideration. Or others reading this thread
may find them useful.

[android-developers] Re: Service vs Singleton
(Not disagreeing with or contradicting anything in Streets of Boston's reply). Applications on Android consist of zero or more components -- activities, services, and broadcast receivers. Processes run components and applications. They're managed separately. An application's components have to run in a process. They do NOT have to run in the SAME process, though by default they do. A process can run components from more than one application. Though by default, for security reasons, it won't. But you can set it up that way for your own applications, typically for efficiency reasons. In other words, processes are just a resource for running your components. And between intervals running your component, that resource can be taken away! Your component will then later be reconstructed in a new process. (Broadcast receivers, since they run only once per instantiation, have no between intervals).

A service can be deleted when it's not in active use by any activity or intent. This can save memory. 2) Under some circumstances, more than one application may be running in the same process. You won't be encountering those situations by accident, but it's an important part of the model nonetheless. In Android, process != application. 3) By using a service, you get control over when and how your service gets restarted if your application and process get deleted in a low- memory situation. Services will be automatically restarted. Applications, and any singletons they manage, will not, unless they're required by a service being restarted! In a sense, your service continues to exist even when there's no process available to run it in.Once a process is available, your service is recreated and resumed. (This applies to services started with startService rather than binding. But if you want this, you can do both operations on the same service).

[android-developers] Android 2.1 for the ADP2... here it is!
I know a question which is often always popular with us Android developers and users is when will device x get firmware y... Well, I stumbled into an image on www.google.com/mobile from within the UK earlier today, and well, anyone with a ADP2 will be very happy with what they see! Image one: http://www.google.co.uk/mobile/images/mgc3/homepage1.jpg Checkout the Android 2.1 launcher on the ADP2! Image two: http://www.google.co.uk/mobile/images/mgc3/homepage3.jpg Notice the Android 2.1 gmail notification icon in the notes bar! If you visit www.google.com/mobile from within the US, you will likely see a Nexus One next to the iPhone and not the Magic.

[android-developers] Re: how to get device's movement speed?
I see now he's asking about pitch roll and yaw velocity rather than x,y and z velocity. The simple case of pitch and roll tilt is detectable with a 3 axis accelerometer. Can't do yaw. That's what the magnetometer is for. So if you can get pitch and roll 20 times a sec (atan2(y,z) and atan2(x,z)), you can get pitch and roll rate 20 times a sec. So now we know the phone pitching at 90 degrees per second. What do we do with that? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Sense of AnimationDrawable and of Animation classes at all
Hello, I experimented with frame animations to use them in a game. It seems that it's obviously the easiest way to load all Bitmaps in an array of Bitmaps and to draw every thread tick the next frame to the canvas. Before I tried out making animations with AnimationDrawable. First of all it is to draw to the background of an (Image)View. Then the background is to read into an AnimationDrawable which is usable. But what can I do with that because as I tried to use animation classes like AnimationDrawable I was not even able to draw the animation to a specific position because it's a view with one background which sticks anywhere on the screen and it is to draw with animation.draw(canvas) instead of canvas.drawBitmap(Bitmap, 20, 20, null) (You don't even have Bitmaps in your animation. That's the next difficulty). I'm not even able to change the speed or the duration of the animation, because I have to define the duration in the XML file once. It's very unwiedly to make a simple animation with this approach. Maybe I don't know how to use this in a meaningful way. Hence I'd like to know what this approach with AnimationDrawable is good for? Do I understand that right that this is not intended as usage in games? Up to now I see no benefit in using these Animation classes.

[android-developers] Re: Out of memory and no useful stack trace
On Apr 11, 3:44 pm, HippoMan hippo.mail...@gmail.com wrote: My android app is getting an Out of memory error without a useful stack trace. It occurs after I have repeatedly re-invoked its main logic through a menu interaction, which leads me to believe that there's a memory leak somewhere. I say that the stack trace isn't useful because it doesn't include references to any of my own code. There are no references to my own code in the logcat output, either. The problem with OOMs is that the thread/code fragment that will trigger the OOM is not necessarily the one that leaked memory. This is probably what you are observing. It is just bad luck that the Android message loop triggers it as it is trying to allocate memory that has been used up somewhere else. I'm wondering if any of you can help me figure out where my memory leak might be occurring, given my stack trace and my logcat output. Why not create a series of heap dumps over time and analyze their delta using the Eclipse Memory Analyzer (MAT)? That should point out where the leak is originating from. You will need to convert the Dalvik heap dump to Sun's .hprof format before MAT can read it.

[android-developers] Re: Out of memory and no useful stack trace
You should at least have an idea/logs on the methods which creates
OOM, you can encapsulate into a :
try {
bigMethod();
}
catch(java.lang.OutOfMemoryError e) {
all objects = null;
System.gc();
System.runFinalization();
}
Maybe you can also use :
Runtime.getRuntime().freeMemory()
Runtime.getRuntime().maxMemory()
Runtime.getRuntime().totalMemory ()
to know if you have to stop what you are doing : properly.

[android-developers] Re: Generating a static HashMap from resources?
Yep,
Use reflection on the R.string class for strings.
Or use reflection on the R.drawable class if you need to map strings
to drawables.
Query the (publicly) declared fields of R.string using reflection.
The code below doesn't follow your example mappings exactly, but
you'll get the idea:
String key = foo;
Field stringField = R.string.class.getField(mymap.get(key));
int stringFieldId = stringField.getInt(null);
String stringFieldValue = getResources().getString(stringFieldId);

Suppose the following items exist in strings.xml:
string name=string0foo/string

element name=abc@+id/string1/element
element name=@+id/string2@+id/string3/element

public static final class map {
public static final MapString , String mymap = new
ConcurrentHashMapString , String() {{

put(abc, bar);

}};

[android-developers] Re: Generating a static HashMap from resources?
Just what are you trying to achieve?
If you're actually wanting a hash map, efficiently populated on class
loading, then Streets of Boston's approach won't help you -- nor will
aapt.
To do what you actually ask for, you could write an XSLT script to
generate the necessary java code.
One of the things you'd have to deal with is handling the @+id/string0
stuff. Well, actually that makes no sense at all. I think you mean
something like @string/string0? You'd have to make your XSLT script
handle your strings.xml other values files, and map to the appropriate
strings. That's probably easiest done as a separate step to
consolidate them into a single temporary file.
In other words, it's not all that hard to create something like this,
given a compelling reason. Do you have a compelling reason? Is there a
reason to not just read the XML resource and process it at runtime?

In my app, I'd like to define some static resources in an xml file
which can be accessed via a HashMap. I know I can do this at run time
in a manner similar to the one which is described here:
http://groups.google.com/group/android-developers/browse_thread/threa...
However, since my HashMap will be a non-changing resource, I'd like to
precompile my xml into a static HashMap in a manner that is similar to
how the aapt utility precomplies the data in various xml files into
R.java. Furthermore, I'd like the keys and values to be expandable via
the @+id/item convention, as follows ...
Suppose the following items exist in strings.xml:
string name=string0foo/string
string name=string1bar/string
string name=string2quack/string
string name=string3oink/string
Then, I would like to be able to do something like this in order to
specify my static HashMap:
?xml version=1.0 encoding=utf-8?
map name=mymap
element name=@+id/string0foo-item/element
element name=abc@+id/string1/element
element name=@+id/string2@+id/string3/element
/map
The resulting generated code in R.java would look something like this:
public static final class map {
public static final MapString , String mymap = new
ConcurrentHashMapString , String() {{
put(foo, foo-item);
put(abc, bar);
put(quack, oink);
}};
}
Is there a way to do anything even remotely similar to this under
Android, perhaps using aadb?
Or am I out of luck?
Thanks in advance.
