[android-developers] Re: Facing serious problem with static objects
What is the reason that your HashMap and arrays are static? Perhaps
they are a component of each instance of your Activity, rather than
having a single HashMap and arrays for all instances?

[android-developers] Re: Best HTTP Request Method
I think that it is automatic. Just be sure to keep your HttpClient object around for as long as you're going to be using it. For example: create the HttpClient in your onCreate() and close it in onDestroy() for your activity. On Jan 1, 10:45 pm, SizzlingSkizzorsProgrammer wrote: > Thanks a lot!

[android-developers] Re: Any Tips for implementing free versions of applications?
Thanks, I've just uploaded a trail version. Because it was a puzzle game that takes a certain length of time to do I just made it time out after 2 minutes. They can still keep using it, but only for 2 minutes at a time, which is enough to do puzzle in easy level, but not in medium or hard unless you are some kind of genius with very fast fingers. This way I also don't have to check if they are reinstalling where one would have to leave some kind of data on the phone or keep a record of owners in a remote database or something like that. I think the idea of tracking usage and a link direct to the market is a good one. But I don't know how you tell what the exact direct android market URL to an application is on the phone. Anyway, thank you for your advice. I think when I make something a bit larger/better I might go about spend more time on such things. I did put a hit counter on the associated web site at least just to see if anyone visits the site. If it gets busy, then maybe I could put pay per click adverts on it or something, but I doubt it will get that busy.

[android-developers] Facing serious problem with static objects
Hi guys, I am facing a problem in my application.
I have a few static arrays and Hashmaps in my app which i fill in when my
Activity starts.Then this activity later launches another Activity. Now
user presses Home button of Back button and again restarts the app, even
then the static objects remain in memory. I beleive this is default android
behaviour.
I have an example app.
package com.cm.test;
import java.util.HashMap;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
public class MyActivity extends Activity {
public static HashMap hMap = new HashMap();
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Log.i("***","Hash map size = "+hMap.size());
hMap.put("Alok","Alo");
hMap.put("Jitu","Jit");
Log.i("***","Activity onCreate() called");
}
@Override
public void onDestroy()
{
Log.i("***","Activity onDestroy() called");
super.onDestroy();
}
@Override
public void onResume()
{
super.onResume();
Log.i("***","Activity onResume() called");
}
@Override
public void onStop()
{
super.onStop();
Log.i("***","Activity onStop() called");
}
}
Output First time is Size = 0. for 1st launch, Next for every launch ,
HashMap size is 2... If i use ArrayList , the size of ArrayList goes on
increasing.
I dont want this to happen.One thing was that to clear the HashMap in
onDestroy() or in onStop() in case user presses Home button. But my Activity
launches another ListActivity in it. So the alternae option is to clear the
Hashmaps in onDestroy() | onStop() of this activity.
I am not much clear when the Activity exits. From the posts that i have read
i found few things here
http://groups.google.com/group/android-developers/browse_thread/thread/4c1b8955ebfd5799?pli=1
The manifest part android:clearTaskOnLaunch=true does not work in my case.
What do you people suggest in this case?
Thanks,
Alok.

[android-developers] Re: Touch handling sleep not helping enough on 1.5/1.6
Were your results of 95% achieved while you were really pushing the GPU? I've found that if I do absolutely nothing but sleep for 16ms and return true, I STILL get massive slowdown. It has nothing to do with my architecture. I'm pushing the GPU down to about 30FPS with a 6ms update and so it seems that the more CPU/GPU time my game needs, the worse this problem is. No problems on the Droid, of course. Only on 1.5 and 1.6 devices. I've tried implementing the sleep in both onTouch and dispatch and they seem to have the same result. Any other ideas?

Hi Rui Wu, I got the solution of the second problem. Actually, i have used the same string value for the both fields. It means i have used the same string value for the edittext in the first activity as well as in second activity which has also one edittext. When i press next button it takes the string, entered by the user and it shows in the edittext of the second activity. By the way, thank you for communicating with me.

upload a paid version too, and in the free version keep track of how many times they play or how long they play with preferences and then don't allow them to start a new game and also give them a button to take them directly to the market with your paid version.

Re: [android-developers] Re: Touch handling sleep not helping enough on 1.5/1.6
Hi, Just off the top of my head... * Research event propagation order and catch the event as early as possible (view before activity?) * Be sure to return true to stop propagation from your handler * Look into other methods to catch the event stream besides the onTouchEvent override My experimentation on 1.5/1.6 (many months ago) showed with a short pause (20 ms, if I recall correctly) brought frame rates to about 95% of what they were with no touch events. Thus, what your experiencing might be influenced by something else in your architecture, or perhaps one of the first bullets above.

[android-developers] Updating a unique AppWidgetProvider from a Service
Here is my issue, I want to be able to update a specific AppWidgetProvider (home screen widget) from a custom service class. I have to build the remote view in the service because I'm also doing some networking in there, which takes some time. The problem is that I can't figure out how to update a specific widget (individual widgets can have different update intervals, using the alarm manager). If I wanted to do it from the onUpdate of the AppWidgetProvider I could just call appWidgetManager.updateAppWidget(appWidgetId, remoteView); Does anyone have any experience with this or any suggestions? -theSmith -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Re: Best HTTP Request Method
You might also want to run a method trace around your network activity
to see where the most processing time is spent. The results you get
wont be in actual time, but a relative time just because method
tracing is slow.
Just wrap you code with a start and stop calls, and make sure to have
the writing to external storage permission in your manifest.
// start tracing to "/sdcard/calc.trace"
Debug.startMethodTracing("calc");
// ...
// stop tracing
Debug.stopMethodTracing();

[android-developers] How can I get the highest framerate with this quellcode?
Hi!
I am programming a game with the following quellcode.
I am just using ImageView's which I move around and I have to handle
some touch events.
What do I have to change to have the highest framerate?
If I remove this block
try
{
Thread.sleep(45);
}
catch(InterruptedException ex) {}
the graphics don't get painted and I see nothing.
If I do NOT remove this block, the graphics get painted but I do not
have the hightest framerate and the graphic is stuttering.
How can I solve this problem?
Greetings, Martin
---
Here is the quellcode:
//package
//imports...
public class LeonardFrog extends Activity implements FrogLanded
{
//declaration of variables...
private OnTouchListener jumpListener = new OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
// do something...
return true;
}
};
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
updatePhysicsDraw();
(new Thread(new AnimationLoop())).start();
}
private synchronized void updatePhysics()
{
// This function calculates all new positions of ImageView's
}
public void onDraw ()
{
// This function moves many ImageView's around
}
private Handler handler = new Handler() {
@Override
public void handleMessage(Message msg) {
Global.calculating=true;
updatePhysics();
onDraw();
Global.calculating=false;
}
};
class AnimationLoop implements Runnable
{
public void run()

[android-developers] how do you draw a new line?!
This is really frustrating, I am trying to get a carriage return drawn
in my custom view and nothing is working. I have tried
'System.getProperty("line.separator")' but that makes it say null and
I have tried '\r' and '\n' and those just both draw a little square.
I am using the canvas.drawText meathod. Thanks for your reply!

[android-developers] onContextMenuClosed() not called under 2.x?
Dear Experts, In one of my applications I programmatically open the context menu when something is clicked in my MapActivity overlay. This works perfectly under 1.x as well as on my 2.0 Milestone. I've used showContextMenuForChild() historically, but openContextMenu() does that same thing. As expected onCreateContextMenu() is called to build the menu and then onContextItemSelected() is called when something is selected. So far all is well. The odd thing is that under 1.x the onContextMenuClosed() method is called when I press the back key, but not so under 2.0. This confuses states for my app since I need to know whether menu is shown or not - or maybe there is a way to know this that I have not (yet) figured out... Is this a deliberate change or should I file it as a bug? Googling comes up pretty dry (stuff that is over a year old). Anyone with a 2.0.1 Droid that would care to test whether this has already been fixed? (The ETA for Milestone 2.0.1 seems hazy still, but it appears that at least one of my reported bugs has been fixed in 2.0.1 event though it isn't flagged as such.)

Re: [android-developers] Re: Best HTTP Request Method
I've seen 5 sec occasionally getting an rss feed of about 28 KB using java.net.URL.openConnection().getInputStream() and then parsing it with SAXParser. It looks like you're doing a POST to send form data(?) so you may have to stick with HTTPClient. If you're doing frequent requests, you can probably take advantage of HTTPClient's "keep-alive" connection management. If you're looking for optimizations, I strongly suggest you create a test app which performs the same request you're having performance problems with. Collect more data, such as the size of the request and response. Try the same request from a different platform (like your laptop or desktop). Compare the network paths between the desktop and Android to the server. I know you'd like to just get an answer "do this/try this". I hope that by looking into the problem in more detail you''ll find a solution.

About 5 seconds, which isn't unbearable, but considering my app needs frequent requests some kind of optimization must be possible.

I guess, the default Android's way is the best. Of course, you can add more libraries, but then that would be redundant. I hope Google has already taken care of the performance part.

Considering that the execute method's latency includes network and server times, on what basis do you think it's taking too long?

If yes then you can > understand it easily what I am saying. > This is API is not really blocking the thread -- it is running a nested event loop, until the user responds to the dialog. This kind of behavior is very deliberately not implemented in Android because it results in poor application interaction behavior and edge cases, which is especially problematic in an environment like a cell phone when an application must be interruptible at any time. For example, if your application is sitting there blocking its main thread like this, and the user receives an incoming call or handles a notification, what do you think should happen? If we try to pause the activity while in this state to move on to the next thing, we will end up calling Activity.onPause() and all kinds of other questionable stuff while nested down inside of your app. Or if you have a broadcast receiver for, say, the device going to sleep, this code would end up being called from deep in your "blocking" method call. In all of these cases, it is unlikely for the application to really expect this to happen. These kinds of nested event loops are just bad news. PalmOS was the king example of the horror they cause, but even Windows suffers from it -- all those apps that get in weird unresponsive states while waiting on a dialog? MessageBox is often to blame. My strong suggestion: re-arrange your code to not do this kind of thing. You have some method that needs to get input from the user to return a response? Make that method async as well, to return its result in a callback, because if it needs to wait for the user then that is truly what it is. -- Dianne Hackborn Android framework engineer hack...@android.com Note: please don't send private questions to me, as I don't have time to provide private support, and so won't reply to such e-mails.

[android-developers] Re: Google Analytics
Hi, My guess is that you have to call tracker.start() for each Activity, as it says this in the example: "Then call its start() method, passing the web property ID *and activity being tracked*." But that's just a guess... So I've posted those questions in the maybe more appropriate discussiongroup http://groups.google.com/group/google-analytics-api Post: http://groups.google.com/group/google-analytics-data-export-api/browse_thread/thread/b3794b6455a1d399 tracker.stop() you have to call when your application is closing. So onDestroy() in your last Activity or onTerminate() in your Application i guess again. But that would mean each onCreate() tracker.start() does not need to have a matching onDestroy() tracker.close() call? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Re: aapt and using shared images
I hadn't thought too much about that but had briefly considered it. I'm trying to use these images directly as resources so putting them in assets would require a fair bit more code to get everything loaded up into drawables for use as icons as such (at least, best I can tell it would take more code). At the moment I'm leaning heavily toward the 'copy over to my res/ directory' option because that gives the benefit of everything working cleanly in Eclipse as well. I guess I'll toss this into the pile of feature requests for a future release: ability to have resources in other directories elsewhere in the developer's file system.

[android-developers] Re: com.android.camera replaced by com.motorola.camera
Thanks very much. This "best practice" outline is worthy of an
official Android blog.
Otherwise developers are going to come up with their own
misunderstandings (like assuming the com.android.camera component will
always be there - not a terribly unreasonable assumption although it
violated the rule against depending on classes outside android.jar).
Two followup questions about intent resolution - It is unclear to me
why the browser was chosen (we don't know what URI was actually
supplied). The API doc for android.content.Intent says "where no
explicit type is included in the Intent, instead the scheme of the
intent data ... is considered". In this case the type WAS included.
So is it correct to say the scheme would NOT be considered in the
resolution? Second question: If there is more than on matching intent
filter doesn't the platform put up a chooser automatically (seems like
I saw that somewhere)?
Happy New Year.

[android-developers] Downloader activity
Hi there, I have integrated the downloader activity (Google provided) into my application.. On the whole a very straight forward process. A problem I have though, is, after the downloader has completed the window disappears and nothing happens. If I hold down the HOME key I see my app and if I click on it my appss window comes up and runs correctly. Also when I run it subsequently it works correctly. Has anyone else experienced this? It certainly looks like the downloader should trigger my app when it is done; I am not sure if the window is just not getting focus or someething. It is a fullscreen GL app. Any ideas?

Re: [android-developers] Re: blocking UI thread when Yes/No AlertDialog is displayed
@Swapnil, when you say that you cant call Alert Dialog from non ui thread ,
you can do that using a Handler as i said.Did u try that out ? It works in
my case where i do an an AsyncTask (seperate thread)in which i communicate
with the server and based on response i decide which screen to show. For
this i call the sendEmptyMessage which is handled by the Handler which is
written on the UI thread.
Thanks,

[android-developers] Custom Layout
What's the deal with the custom layouts? I implemented a custom layout class and began defining xml layout using my new class. Than I realized that I can't just add the child views that way one can add views to the predefined layouts. I had to do it manually modifing the xml. Than I found out that the onMeasure/onLayout methods were getting wrong getMeasuredHeight/getMeasuredWidth results. Why??? (I realy feel like cursing here but what's to point.) On the other hand, If I do all of it programatically, instantiate the layout object in the activity and add the child view to it, all works fine.

Re: [android-developers] Re: When the new activity starts, the data of previous activity is gone.
Hi Pranav, I didn't catch the point for your second problem. Do you want to pass the value of edittext in first activity to second activity, then show the strings in the edittext of second activiy. If so, you can try in the similar way as the first problem. BRs, Rui 2010/1/1 android09 > Hi Rui Wu, > > Thanks a lot. It works very good and perfectly as i want.

Hi Rui Wu, Thanks a lot. It works very good and perfectly as i want. Now, i know that where was my problem. Actually, i had not added this line/lines : " mData.strFirstName = edFirstName.getEditableText().toString();". That's why i was not getting any result. Now, i got it. I have also one query. I have two activities. First activity consist on edittext and button whereas second activity consist only edittext. When i write in edittext of first activity and press a button of first activity than the edittext of second activity should get the same string. Actually, i want to get the email id from the first activity and also it should be automatically get in the edittext of second activity. If you have any idea about it, please tell me.

Re: [android-developers] Android and VOIP
hi, guys: i have done some test. it really worked in a very first step... android can support playing and recording the speach at the same time (the attachment is my test code, head phone is necessary or it will become noisy soon). i believe the next step is to use amr_nb/gsm/g.729 (jni modules is prefered) to compress the pcm16 data into smaller RTP packages, then, send them through wifi or 3g network... but i think the diffculties are not focused on these things, how to keep the android handsets always on-line with lower power consume is the major or we can't let the answer peer response immediately. i have an idea which to use the common tel-line to activate the answer-call peer (just ring 1-2 times then hung up), then the app will catch this event, start the activity and connect to the remote voip server, but how can i control the tel-line signal and identify which call is from voip app or from the regular missed call ... if keeping the caller and answer peer on-line at the same time is the pre-condition, (no matter sip or some other heartbeat like mechanism) the current fact is the phone will use up the battery very soon... any ideas ? great thanks. 于 2010年01月01日 16:55, soft buzz 写道: > Hi, > do u have idea on Android/VOIP working? share here > thanks > buzz > -- > You received this message because you are subscribed to the Google > Groups "Android Developers" group. > To post to this group, send email to android-developers@googlegroups.com > To unsubscribe from this group, send email to > android-developers+unsubscr...@googlegroups.com > For more options, visit this group at > http://groups.google.com/group/android-developers?hl=en -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Has anyone written a 2D scene graph yet?
I am struggling with drawing on my custom View. I can make it all work but just not very efficiently. I am using invalidate causing the entire screen to be redrawn. I only need to redraw a small portion of the screen. I tried calling invalidate with a rectangle but that left everything else black. I don't know what is causing everything else to go black if I only invalidated a small rectangle. I see many posts on these similar issues and think that everybody would have a much better experience if there was a 2D scene graph API for android. Then I can just worry about my scene primitive attributes and let the scene graph engine handle all the drawing in the most efficient way possible. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
