[android-developers] Re: Android Physics Engine
OK, for anyone interested in my simple physics demo, check out: http://www.antonstoys.com/android/BallPit.apk It's pretty basic, but it shows that you can do some amount of physics on the G-phone at a reasonable rate. And as always, there are many improvements to be made. :) -Anton On Mar 31, 2:12 pm, Anton socialhac...@gmail.com wrote: I'll definitely post the app tonight for you guys to check out (at work now). I am an embedded systems programmer by trade. But I do physics toys for fun and am just getting into Java/Android optimizations. I will point out that optimizing for Java and optimizing for Android are very different. As people have pointed out before, the key things to be careful with on Android are memory allocation and floating point math. I've removed both of these from my physics loop. I also found that function call overhead was quite large and had to manually inline all of my fixed point math code. I think that with the correct spatial data structures I can get a couple hundred objects interacting. I have a 2D rigid body physics engine that is currently all C++ (no exceptions or templates or RTTI or multiple inheritance) that I may port over as well. However, having said all of that, I think it may be the case that we will just have to wait until a native SDK is available to really write a top notch physics engine. It's sort of the perfect example of a piece of code that doesn't need anything more than libc and JNI bindings. And since you only call it a couple times per frame the JNI overhead would be well amortized.

Clark, i'd definately host any .apk's on my own site, I wouldn't put it on the marketplace if it wasn't a finished app - do people actually do that?! I think i'll stay away from developing games with physics for the time being and concentrate on something else, I cant see it being feasible to include it any time soon which is a real pity.

The version of PulpCore that I integrated simpull with did not support Chrome, but you should be able to see it in IE, FF Safari. It is nice to take a look at that demo to get a feel for what the engine is capable of, but the performance does not translate over to the fixed point branch/version of simpull when running on Android. I ran tests on both the emulator and the actual device and there was a significant increase in performance because of the fixed point implementation, but I got very frustrated that it still did not support the amount of objects in a scene that I considered good for a physics-based game. It seemed to handle ~10 objects moving and colliding OK. It has been a while since I was playing with it, so I do not really remember the exact number of objects or the frame rate. I mostly remember being upset with it. I am leaving the physics ideas for games out of the picture when thinking Android for now. Someone would have to write a ground up engine with all the performance and memory concerns of Android in mind, which was not the case with Simpull.I created it for applets, then thought to port over to fixed-point for Android. It works well with small scenes, but certainly not the staple engine to use in my opinion. Also, Phys2D will not run worth a damn on Android. I tried it and I even went through some heavy performance tuning. Garbage collection is the major issue even after all I did. I seriously doubt JBox2D will run well either. I'll stick to what I said earlier, a ground-up solution by someone smarter than me is probably required.

[android-developers] How to make a ListView adapt to dynamic element sizes?
Hi, I am struggling over another layouting problem again. I render a ListView with ellipsized TextView elements, but those text views can expand in size when the user clicks it. The problem is: If the ListView doesn't already take the whole screen (e.g. because the total height of all visible elements is smaller than the screen height), then when expanding an element, the ListView's size doesn't also expand accordingly, still obscuring most parts of the now taller text view. I have tried practically everything that seemed reasonable to me to make the ListView get aware of the new height of its children, including calls to: invalidate() measure() recomputeViewAttributes(textView) on all participating views (the list view and its elements), but nothing works. What am I missing? How can I programmatically tell a container view to look at its children again in order to resize if necessary? Thanks!

[android-developers] Re: Performance: pre-instantiate activities on app launch? Good practice or not?
Thanks for your reply Dianne. As to profiling, I looked at traceview, but seems to be a bit overly simplistic to actually profile a whole app. What I understand from the documentation, what it actually does is measuring the time it takes for a single method to complete. That's not a terribly useful information if you want to see the big picture, however (i.e. get answers to questions such as: how much time does the app spend in which parts of the code base?). Are there any plans to make traceview a tad more capable? That would be great news!

[android-developers] Re: Fling on ListView
Romain, thanks for pointing out onInterceptTouchEvent()! I'll take a look at that method ASAP. As to the it was meant to be part of the UI design, I really wonder why practically none of the apps shipped with Android use gestures then (I mean, apart from scrolling up or down of course)? I can only think of the home app right now. In contrast, the iPhone makes very consistent use of flings to navigate back and forth between app screens. We tried to implement this for our app, but as I said, it wasn't actually an easy thing to do, because, for example, Android doesn't actually define what a left or right fling is (in terms of velocity and so forth). So, another app may have a different understanding of this, and react differently to left and right flings (in terms of when to interpret it as such, not in terms of the resulting action, which of course may be different), giving navigation in the platform an inconsistent feel. That's what I meant with messy and fragile. Cheers, Matthias On Mar 29, 8:16 pm, Romain Guy romain...@google.com wrote: Doesn't look like fling support as known from the iPhone was ever meant to be part of Android's UI design.

[android-developers] Re: How to make a ListView adapt to dynamic element sizes?
Well, I found a really ugly workaround. That workaround is based on my observation that the problem described does only occur if the ListView's layout height is set to WRAP_CONTENT. So, since I use a custom list adapter, I now call listView.getLayoutParams().height = LayoutParams.FILL_PARENT whenever a text view is about to be expanded... the reason I do not statically set its height to FILL_PARENT is because then it will draw line separators below the last element, which looks ugly if it doesn't expand to the bottom of the screen. It works... but, yuck! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

But my current usecase is not to detect motion, but hold. I have a

If user click on it, it will scroll other widget content in one step.
If user touch hold on it, it will scroll the widget content one by
one continually in about 800ms interval.
Currently I implement the behavior by setOnClickListener() method for
the click event.
For touch hold, I override dispatchTouchEvent() method and check for
the holding status by checking the move shall be less than 10 pixels
and event.getEventTime() - event.getDownTime() 800ms for
MotionEvent.ACTION_MOVE event.
It works fine in G1 but not work in emulator.
Is there any better solution?

That's simply because you cannot hold your finger still. With a mouse
cursor you have a 1px precision, with a finger, it's a lot more. The
way to work around this is simply to use thresholds when you try to
detect motion. For instance in a ScrollView or ListView a scroll
happens only if the finger has moved by 16 pixels or more. You can use
the same values as the framework by looking at the ViewConfiguration
class.

alive thread, when the device goes to sleep. I program a simple
activity that will create and start a thread printing HERE AM I
repeatedly through Log.d. I expect the thread would be stopped after I
echo standby /sys/android_power/request_state. The screen is off,
but the thread still keeps alive and prints out HERE AM I. I don't
know why the thread can't be stopped. I test this through emulator
(1.5cupcake) and G1(1.1?), but the results are the same. Could anyone
give me some suggestions or hints about this question? Thanks in
advanced.
The following is my simple activity.
===CODE
HERE=
ublic class TestServiceDroid extends Activity {
PowerManager.WakeLock lock;
Thread h;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Thread h = new Thread(new Runnable(){
public void run(){
while(true){
try {
Log.d(TEST SERVICE,HERE AM I);
Thread.currentThread().sleep(3000);
} catch (InterruptedException e) {
// TODO Auto-generated catch
block
e.printStackTrace();
}
}
}
});
h.start();
}
}
===CODE
HERE=
Best regards,
Augustin.

[android-developers] Mirrored TextView
Hi,
I want to create a TextView with the text mirrored vertically.
I tried this code, but it doesn't show anything...
Does anyone have an idea?
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
rl = (RelativeLayout) findViewById(R.id.Rellayout);
MirrorView speed = new MirrorView(getBaseContext());
speed.setText(Testtest);
rl.addView(speed);
}
private class MirrorView extends TextView {
public MirrorView(Context context) {
super(context);
// TODO Auto-generated constructor stub
}
@Override
protected void onDraw(Canvas canvas) {
canvas.scale((float) -1.0f, (float) 1.0f, (float)
(canvas
.getWidth() / 2), (float) (canvas.getHeight
() / 2));
super.onDraw(canvas);
}
}

[android-developers] send bytes[] buffer in httppost
Hi Experts,
i need to post image on server by http post with some parameters, here
is a piece of code i am trying:
List NameValuePair nvps = new ArrayList NameValuePair();
nvps.add(new BasicNameValuePair(message[content],abc));
nvps.add(new BasicNameValuePair(message[image],?)); // here i need
image buffer
here is the buffer but this is writing directly to my connection
output stream which i dont have in above httppost,
InputStream is = this.content_resolver.openInputStream(imagefile);
while( (bytesRead = is.read(buffer)) 0) {
wr.write(buffer,0,bytesRead);

}
any solution?

[android-developers] A ppp change in Android
Hi there
Currently in .../external/ppp/pppd/auth.c, function check_passwd,
somebody write
{
#if 1
return UPAP_AUTHNAK;
#else
.
This basically means PAP auth is not allowed on android. Is there any
reason behind this? Can I savely change the #if 1 to #if 0?
thanks,
Xia Weizhong

[android-developers] Re: ListView elements in Dialogs never expand to full width
Okay, I found (once again), a rather ugly workaround for this: Putting the textview in layout object does the job. Like this: ?xml version=1.0 encoding=utf-8? RelativeLayout xmlns:android=http://schemas.android.com/apk/res/ android android:layout_width=fill_parent android:layout_height=wrap_content android:paddingLeft=14dip android:paddingRight=15dip TextView android:id=@+id/list_dialog_item android:layout_width=fill_parent android:layout_height=wrap_content android:minHeight=?android:attr/listPreferredItemHeight android:textAppearance=?android:attr/textAppearanceLarge android:gravity=center_vertical / /RelativeLayout But, that layout object is unnecessary overhead of course Is this a bug maybe? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

Per the documentation: You can not receive this through components declared in manifests, only by exlicitly [sic] registering for it with Context.registerReceiver(). In your case, you are trying to receive this through a manifest-declared receiver, which will not work.

Thanks for the demo Anton, It certainly runs much smoother than the Phys2D and JBox2D engines I have tried and you have more objects being simulated - so you must have done something right ;) I would expect it to run 2-3 times faster on an actual device too from what I have read.

When sending a $GPGGA sentence after the $GPRMC, the locationlistener gets controll and location is shown. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

If your list-view uses a (list-)adapter (or a subclass of this), did you try to call notifyDataSetInvalidated() on the adapter?

So, since I use a custom list adapter, I now call listView.getLayoutParams().height = LayoutParams.FILL_PARENT whenever a text view is about to be expanded... the reason I do not statically set its height to FILL_PARENT is because then it will draw line separators below the last element, which looks ugly if it doesn't expand to the bottom of the screen.

As people have pointed out before, the key things to be careful with on Android are memory allocation and floating point math. I've removed both of these from my physics loop. I also found that function call overhead was quite large and had to manually inline all of my fixed point math code. I think that with the correct spatial data structures I can get a couple hundred objects interacting. I have a 2D rigid body physics engine that is currently all C++ (no exceptions or templates or RTTI or multiple inheritance) that I may port over as well. However, having said all of that, I think it may be the case that we will just have to wait until a native SDK is available to really write a top notch physics engine. It's sort of the perfect example of a piece of code that doesn't need anything more than libc and JNI bindings. And since you only call it a couple times per frame the JNI overhead would be well amortized.

I ran tests on both the emulator and the actual device and there was a significant increase in performance because of the fixed point implementation, but I got very frustrated that it still did not support the amount of objects in a scene that I considered good for a physics-based game. It seemed to handle ~10 objects moving and colliding OK. It has been a while since I was playing with it, so I do not really remember the exact number of objects or the frame rate. I mostly remember being upset with it. I am leaving the physics ideas for games out of the picture when thinking Android for now. Someone would have to write a ground up engine with all the performance and memory concerns of Android in mind, which was not the case with Simpull.I created it for applets, then thought to port over to fixed-point for Android. It works well with small scenes, but certainly not the staple engine to use in my opinion. Also, Phys2D will not run worth a damn on Android. I tried it and I even went through some heavy performance tuning. Garbage collection is the major issue even after all I did. I seriously doubt JBox2D will run well either.

[android-developers] OpenGL SurfaceView renders black on first start - works after orientation change
I have an Activity that was created based on the TriangleRenderer
example. It works flawlessly as a standalone project, but when I use
it as the tab of a tabhost there is a problem. At startup the whole
activity is just black - I can get touch events and do everything else
but it doesnt show anything. When I change the orientation (and
therefore recreate the activity) it all works well.
Maybe the problem comes from the View focus. My SurfaceView is not
focused when created inside of the tabhost. I tried to fiddle around
with the methods available in my onCreate() and onPostCreate(), but
couldnt find a way to get the SurfaceView focused.
The following sourcecode blocks in the guardedRun() method because
needToWait() is true because !mHasFocus is true. If I exclude the !
mHasFocus, it goes on but shows a black View anyways.
Do you have any idea why it does work after orientation change, but
not at the first startup?
The Activity looks quite simple:
===
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Create our Preview view and set it as the content of our
// Activity
mGLSurfaceView = new GLSurfaceView(this);
mGLSurfaceView.setRenderer(new ContactsRenderer(this));
setContentView(mGLSurfaceView);
System.out.println(focused: + mGLSurfaceView.isFocused() +
focusable: + mGLSurfaceView.isFocusable());
}
@Override
protected void onResume() {
// Ideally a game should implement onResume() and onPause()
// to take appropriate action when the activity looses focus
super.onResume();
mGLSurfaceView.onResume();
}
@Override
protected void onPause() {
// Ideally a game should implement onResume() and onPause()
// to take appropriate action when the activity looses focus

[android-developers] Re: Unused java hardware acceleration on the G1 (was Re: Android game developers desperately need optimised game engine example code ...)
This I cannot confirm. The C64 emulator Mobile C64 runs with AFAIK 10-15% of the original C64 speed on a G1 with its 528 MHz CPU. On my Samsung SGH-i600, with a 624 MHz CPU, the J2ME variant ran at close to 100% of the original C64 speed. This is a factor of 6-10 faster although the device's CPU is only 20% faster. So the Jazelle advantages can be quite considerable, at least for some applications.

Then code that needs to control your thread, just call
myThread.pauseThread() or myThread.resumeThread() and stops the thread
entirely by calling myThread.stopThread();
Note: you could replace 'this' with another object to use for
synchronization.

[android-developers] Re: How to make a ListView adapt to dynamic element sizes?
ListView supports the WRAP_CONTENT height mode but it is really not meant for that. First of all, having a ListView in WRAP_CONTENT is very costly in terms of layout. It is also meaningless. What does WRAP_CONTENT mean for a ListView since the goal of ListView is to virtualize its children? Because of this, ListView just does not support growing or shrinking when you modify its adapter. You should simply use FILL_PARENT for your ListView. And you may find the last divider ugly but *every* ListView in the system behaves that way. Your WRAP_CONTENT ListView just looks different from the rest of the system for absolutely no good reason. Consistency matters. On Wed, Apr 1, 2009 at 6:40 AM, Streets Of Boston flyingdutc...@gmail.com wrote: If your list-view uses a (list-)adapter (or a subclass of this), did you try to call notifyDataSetInvalidated() on the adapter?

On Apr 1, 5:24 am, matthias m.kaepp...@googlemail.com wrote: Well, I found a really ugly workaround. That workaround is based on my observation that the problem described does only occur if the ListView's layout height is set to WRAP_CONTENT. So, since I use a custom list adapter, I now call listView.getLayoutParams().height = LayoutParams.FILL_PARENT whenever a text view is about to be expanded... the reason I do not statically set its height to FILL_PARENT is because then it will draw line separators below the last element, which looks ugly if it doesn't expand to the bottom of the screen.

[android-developers] Re: Fling on ListView
As to the it was meant to be part of the UI design, I really wonder why practically none of the apps shipped with Android use gestures then (I mean, apart from scrolling up or down of course)? We use gestures for scrolling: ListView, GridView, Gallery, MapView, WebView, ScrollView. Calendar uses gestures to navigate between months/weeks/days. Calculator uses gestures to switch between the simple and complex operations. Etc. Using gestures to navigate within an app has a HUGE problem: it is totally undiscoverable. -- Romain Guy Android framework engineer romain...@android.com Note: please don't send private questions to me, as I don't have time to provide private support.

Thank you, I will try to implement this when I have time. I now
understand where my confusion was stemming from. I was under the
impression that each time the CupView Activity was resumed, a new

now see that is not the case, the CupView object is not destroyed and
recreated, thus no new thread to call start() on.

I have tried to use it as stated below, but none of the functions in
the documentation is available that way (i.e when I type db. the
list that shows in Eclipse documentation doesn't include any of the
functions from the SQLite doc except from execSQL):

import android.content.Context;
import android.database.Cursor;

Hello everyone, I was also disappointed with jbox2d's performance so I checked APE (Actionscript Physics Engine) from http://www.cove.org/ape/ . It was converted to java (http://www.cove.org/ape/java_ape.zip) so I started to convert the java version to Android. The performance is quite OK for 10-20 objects at the first start of the app but if you exit with the back key and restart it form the installed copy (either in the emulator or on the dev phone) then it gets slower and slower with each start. If you restart it from the emulator (by reinstalling it) then it is faster again. Neither the pressed keys are not working (probably it is because of my poor Android programming knowledge). Here is a zipped Android project of it. Please experiment with it and send results to here i.e. is it slow for you also after re-re-re-.. staring? www.kotiposti.net/lkelemen/android/testape2d.zip thanks Lajos Kelemen On Mar 31, 9:26 pm, shaun shashepp...@gmail.com wrote: I started going down the path of Object pooling.

Clark, i'd definately host any .apk's on my own site, I wouldn't put it on the marketplace if it wasn't a finished app - do people actually do that?! I think i'll stay away from developing games with physics for the time being and concentrate on something else, I cant see it being feasible to include it any time soon which is a real pity.

The version of PulpCore that I integratedsimpullwith did not support Chrome, but you should be able to see it in IE, FF Safari. It is nice to take a look at that demo to get a feel for what the engine is capable of, but the performance does not translate over to the fixed point branch/version ofsimpullwhen running on Android. I ran tests on both the emulator and the actual device and there was a significant increase in performance because of the fixed point implementation, but I got very frustrated that it still did not support the amount of objects in a scene that I considered good for a physics-based game. It seemed to handle ~10 objects moving and colliding OK. It has been a while since I was playing with it, so I do not really remember the exact number of objects or the frame rate. I mostly remember being upset with it. I am leaving the physics ideas for games out of the picture when thinking Android for now. Someone would have to write a ground up engine with all the performance and memory concerns of Android in mind, which was not the case withSimpull.I created it for applets, then thought to port over to fixed-point for Android. It works well with small scenes, but certainly not the staple engine to use in my opinion. Also, Phys2D will not run worth a damn on Android. I tried it and I even went through some heavy performance tuning. Garbage collection is the major issue even after all I did. I seriously doubt JBox2D will run well either. I'll stick to what I said earlier, a ground-up solution by someone smarter than me is probably required.

[android-developers] Re: MediaPlayer sluggish to play sounds
I think you have to get WakeLock to avoid your media stop when phone
is going to sleep.
Try to use setWakeMode() method of MediaPlayer or if it won't help for
some reason, you can use PowerManager/WakeLock classes directly.
On 1 апр, 04:35, Eric M. Burke burke.e...@gmail.com wrote:
I have an Activity that plays a brief OGG pop sound effect when
bubbles pop. To keep it fast and to ensure I can play several pops, I
create four MediaPlayer instances. I synchronize access to a pool of
instances, so I can play up to four pops at once. Once a sound
completes, I call seekTo(0) and return the MediaPlayer instance to my
pool.
Here is a rough sketch of the code:
// when the activity resumes...
for (int i=0; i4; i++) {
MediaPlayer mp = MediaPlayer.create(context, R.raw.pop);
mp.setOnCompletionListener(this);
mp.setVolume(1f, 1f);
players.add(mp); // put into a pool of available players
}
// when a bubble pops...
MediaPlayer mp = ...get player instance from the pool
if (mp != null) {
mp.start(); // works! plays the pop sound
}
// implement the OnCompletionListener interface
public void onCompletion(MediaPlayer mp) {
// seek to the start so I can play the sound fast the next time
mp.seekTo(0);
return the MediaPlayer to the pool
}
Here is the problem. The pops all work so long as my game is active.
But if I let it sit there for just a few seconds, I see this in the
LogCat console: (on my G1 phone)
AudioHardwareMSM72xx Going to standby
Once this happens, the next several calls to MediaPlayer's start()
method play nothing...but they do cause the audio hardware to wake up
again, so then my sounds eventually (after a few seconds) start
playing again.
My question is, how do I prevent the AudioHardwareMSM72xx from going
to standby mode while my Activity is active?
One hacky idea...I could loop a continuous sound at extremely low
volume level in another MediaPlayer instance to force it to stay
awake. That's not appealing to me.
Ideas?

Disconnect the headset from the G1 phone. 3. Switch off the headset.(Plantronics 320 / Motorola HT820) 4. Put the headset back in discoverable mode. 5. Now initiate a connection from G1. 6. Problem in connecting to Headset message pops up. Note: when a stereo headset is connected in the same way (step 5) , only a2dp connection succeeds and HFP connection always fails. when a mono headset is connected (step 5) , failure happens as it supports only hfp. From my initial analysis , i found that HFP conenction failed because of the RFCOMM connection failure.

Hi,
You can drop the table by writing DROP TABLE tablename IF EXISTS
But after that it is good to do a VACUUM (info about that in the link
below).
I.e the code might look like:
private SQLiteDatabase db;
private static final String TABLE_NAME = name_of_table;
try{db.execSQL(DROP TABLE IF EXISTS + TABLE_NAME);
db.execSQL(VACUUM);}
catch(SQLException sqle){}
