[android-developers] Re: ANR in Album with 100% CPU usage
Yes, ANR's occur because the task doesn't respond quickly enough to user input. This can be caused by a background thread hogging the CPU. I assume you are referring to the Pictures app (which will be called Gallery in Cupcake). We have made some improvements in Cupcake will continue to work on improving performance. It's not an easy problem, given the amount of data involved in a large set of thumbnails. On Apr 2, 10:19 pm, Hank And hank.and.gr...@gmail.com wrote: Hi all, I encounter an ANR in Album.

[android-developers] Re: play video error
It's pretty obvious that the path to your video file is located on
your Windows workstation. You have to remember the emulator is running
Linux in an emulation of an ARM processor. It doesn't have access to
the files on your workstation. You need to copy the video file to the
SD card emulation while the emulator is running using adb push.

[android-developers] Re: Why does not SoundRecoder work on G1
As it is known, the default format to be recorded is AMR. Is it to possible to replace it with another one, e.g. mp3 or qcelp? Frankly speaking, I want to let OpenCore support recording qcelp which is just one type of audio format. Could you please give me some clues about it, or what should I prepare or pay attention to? A summarizing info is also appreciated. Many thanks in advance. I've issue this question at https://mail.google.com/mail/?hl=enzx=1mf4sjv3oovloshva=1#starred/1203efc288afc0b5. I'm sorry if it trouble you again. Please reply it just here. Thanks again. david 2009/4/3 Dave Sparks davidspa...@android.com You can access it via the Messaging (SMS/MMS) application by clicking on attach and selecting record audio. I believe there's also an app in market that exposes a launcher icon for it.

[android-developers] Definite need for a Cupcake SDK release details.
I've just run up cupcake emulator images in the 1.1 SDK emulator under windows and seen something that makes me very nervous about cupcake. Under 1.0, 1.1, and on the G1 the password entry page of one of my companies apps looks as shown in the far left hand image at; http://www.funkyexpenses.com/ Under Cupcake it looks like; http://www.funkyexpenses.com/password-cupcake.png Which is very different and would make it hard for a user to use. To answer the obvious questions; 1. It has a virtual keypad because users asked for it. When cupcake comes they may not want it any more, but for now they do. 2. I know that cupcake is a work in progress, but we're in the month when Cupcake is suppose to be shipping on devices, so clearly broken backwards compatibility could be an issue (yes, I know Vodafone have told some people it'll be 1st of May, but that still means it'll get out to the distributors this month). 3. The dialogue is created from a series of Buttons in a horizontal LinearLayout all in a vertical Linear layout. This may not be the best way to do it, but it works on 1.0 so I would expect it to work on cupcake. So now, more than ever, I strongly believe we need an SDK a few weeks ahead of the consumer device release so we can check to see if things like this are just anomalies in the public branch and are fixed in the full release, or if there may be some reworking needed of our apps.

[android-developers] Re: Definite need for a Cupcake SDK release details.
The layout is actually working. However, Cupcake has new assets for buttons (and other widgets) and it happens that the minimum width of the buttons has changed. I don't know how you set up your layout but it looks like you were relying on that minimum size to get all the buttons aligned (which would be bad since such a layout would break anyway on devices with different resolutions and/or densities, but that's another topic.)

[android-developers] Re: Definite need for a Cupcake SDK release details.
Romain, I accept that it may not have been the best way of doing it, but my main point is that many developers have absolutely no way of checking for problems like this. Now I am fortunate in that my company has a Linux machine that I can download and build the SDK on, but I suspect there are many developers who are either coding on Windows and don't have a spare machine to install Linux on and build a cupcake SDK, or may not have the resources to download the sources from git and run a full build. Even I can't fully test my apps because the Linux box is a headless server, and running the cupcake emulator images in the 1.1 SDK emulator installed on the Windows desktops we have here does not bring networking up. So please, please, please, can we have either a windows SDK, a method of building a windows SDK, or something that will let us test our apps in cupcake.

If you are thinking of providing intents, probably you could present your idea in our developer's group as well: We have already a couple of applications that communicate via open intents, and we are always interested in expanding the range of applications that use or provide intents.

I have been investigating this quite a bit and developing an app to work with PennyTel but i have discovered an issue with the Android OS. Android is not designed to let you replace low level systems in your app and there for there is no way to capture out going sms etc. This means that to write an app that sends all out going sms via pennytel is impossible and that the only way around this is to write your own sms client like ChompSMS and i am sure this will apply to other parts of the phone as well. What i am looking to do is make a reusable system that uses intents to do things. A complete sms application that uses an intent to send the sms so that more sms providers can be added later, a dialer and outgoing call system that will fire an event for another app to make the call etc. What I want is sever apps that use intents not just to open their app but also to choose the outgoing their service uses. personally i want to write one of the outgoing paths and i am looking for some developers who would be interested in writing the more front end apps like the dialer and sms applications. If anyone is interested let me know as it is just too much work for one person and i am sure your apps will be used by many people as more and more people could right services they could be hooked into.

[android-developers] Which one scales with the screen... Dip, sp, px.....?
Given the recent discovery with the cupcake emulator I'm trying to re-work the layout file so it's cupcake friendly and future proofed, but have hit a problem. What I want is for 6 buttons to take up a total of three quarters of the screen width, but I can't seem to find the measurement unit which correlates to this. All I've found is; px : Not screen resolution independent, so something that works on a 320x480 screen won't take 3/4s of the screen on different resolution display. dip : Scales with pixel density and not screen resolution, so the object won't scale up as the physical screen size gets bigger. Pt, in mm : Don't scale with screen size so a 1 unit button is the same size on a 3 or 30 inch screen. sp : Based on font size and there's no guaranteed correlation between font width and screen width. The closest I've got is the following; TableLayoutandroid:layout_gravity=center_horizontal android:layout_height=wrap_content android:layout_width=fill_parent TableRow Button android:id=@+id/button1 android:layout_width=fill_parent android:layout_height=wrap_content/ Button android:id=@+id/button2 android:layout_width=fill_parent android:layout_height=wrap_content/ Button android:id=@+id/button3 android:layout_width=fill_parent android:layout_height=wrap_content/ Button android:id=@+id/button4 android:layout_width=fill_parent android:layout_height=wrap_content/ Button android:id=@+id/button5 android:layout_width=fill_parent android:layout_height=wrap_content/ Button android:id=@+id/button6 android:layout_width=fill_parent android:layout_height=wrap_content/ /TableRow /TableLayout But this results in buttons with uneven widths which is not what I'm after.

The road map ( http://source.android.com/roadmap) doesn't contain much and doesn't seem up to date. And don't get me started on the lack of transparency and predictability regarding *all* things Android Market. Don't get me wrong though. This is not meant in any way as a personal attack against you or in me laying the blame onto you.

These are exactly the sort of objects that could be created in a physics engine when it needs to generate dynamic collision constraints. A good solution in this case is to use a pool of constraint objects because they are all going to be the same size/object. The best solution in my mind would be for the compiler to do escape analysis on the objects and stack allocate them when it sees that they will never escape the function. I have been told that the Java byte code can't reference an object on the stack. It's possible that the Dalvik byte code can, I don't know. I don't have a reference for this, but I assume that Dalvik's inability to optimize small short lived object comes from the fact that it uses a mark and sweep GC. On all of my profiling, I see the GC take at least 100ms to run. For a game that means you miss from three to 10 frames of animation and it makes for a pretty noticeable hick up. And I don't think it's my application that is causing the garbage collector to fire. Unless the OpenGL ES calls do some memory allocation, which is entirely possible. I realize that any background task could move to the run queue and take some time away from my engine, it just happens to be the garbage collector most of the time. :) So the result is that the Garbage collector is problematic for me in two ways. First, it's not optimized to deal with the sort of small objects that tend to make for good encapsulations of mathematical types (like Fixed point number classes or Vector or Matrix classes). And secondly it takes a long time to run when it does garbage collect, resulting in dropped frames. -Anton On Apr 2, 3:32 pm, Mariano Kamp mariano.k...@gmail.com wrote: It's maybe a bit off topic, but how do you know that Android's gc is rudimentary?

Yah, I agree that the real complexity of a physics engine comes from joints and contact constraints. The constraints in my demo are simple minimum distance constraints. I have a 2D rigid body physics engine that I'm thinking more and more about porting over to Android as well. This demo was more of a calibration for myself to see how much computation I can do, and what optimizations lead to the largest improvements. I'll probably turn it into a fun toy for the Market and then look into rewriting my rigid body engine for Android. Reading through Simpull I noticed that you allocate a new Vector3f in your Verlet update routine. I think that will be a killer on the Android platform because of it's rudimentary garbage collector and limited RAM. My solution was to allocate an array of fixed point numbers, four per ball. Effectively a vector pool that didn't require any management because the number of balls never changed.

Yes, Eclipse sucks. BTW, does anyone now know hard or easy it is to write plugins for Eclipse, especially plugins which generate code, or parse and/or modify code in code windows? I'd like to create a plugin which when given an activity class, and a layout, used as a view in the activity would generate typed members for all widgets and will write the code to find them, e.g. if there's a layout and 2 buttons w/ resource ids R.id.button1 and R.id.button2 in a nested layout w/ id R.id.buttonPanel, the plugin would generate the following code: private LinearLayout mButtonPanel; private Button mButton1; private Button mButton2; and in onCreate it would insert: mButtonPanel = (LinearLayout)findViewById(R.id.buttonPanel); mButton1 = (Button)mButtonPanel.findViewById(R.id.button1); mButton2 = (Button)mButtonPanel.findViewById(R.id.button2); This will avoid some hair-pulling errors I occasionally make (and probably other guys too).

I would like to overlay some effects on the resulting image that is produced by my custom view. It would seem that my CustomView's onDraw is only being called after before all of it's children's onDraw methods which basically is burying the changes I want to make. Makes sense, but does anyone know halfway decent way to do what I'm asking?

[android-developers] Re: How to scale a view without scaling its children ?
Here's a short exemple : The XML file : ?xml version=1.0 encoding=utf-8?

Is there a way to avoid the button and the textview to be resized. Or is there a way to play an animation which resize the height of my LinearLayout without modifying its content ?

If the children of avieware using the android:layout_height or android:layout_width property, for example, in a way that is tied to the parent (such as, android:layout_height=fill_parent) then I imagine changing the size of the parent should, as defined in the xml, change the size of the children. If this is how your xml is set up and you don't want this behavior, you should probably change the xml for the children.

I have kind of same problem to solve I have same code base from which i have to build to different apps using two different resources folders and may be some extensions in terms of extra activities etc... so let say all my base code is in com.acme.product.base And I have packages like com.acme.product.ui1 com.acme.product.ui2 Activities in base have references to R. which will be put under one of UI packages by specifying package name in the manifest . So to make it build , i understand, that i'll need an ant script which will put correct include to com.acme.product.ui1.R or com.acme.product.ui2.R base to all java files during build time . First question how i do this ( i'm not really savvy in ant scripts so direction will be appreciated ) Second - is the ant script a right solution in this case or there is another way . I've seen some company ( i think Paragon ) doing that kind of builds for the dictionaries and looking of the best way how i can get this to work . --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: WebView bug with pageDown() ?
I did that also but if you invoke view.pageDown(true) inside
onPageFinished(Webview view, STring url ) it produces the same
behavior as explained before. The only way this method seems to work
(producing a very poor user-experience) is by just invoking inside
the onPageFinished something like the following:
In the activity using a WebView object named webView:
class ViewUpdater implements Runnable {
public void run() {
webView.pageDown(true);
}
}
and a class extending the WebViewClient ...
void onPageFInished(WebView view, String url) {
view.postDelayed(new ViewUpdater(), 150);
//The following does not work either.
//view.post(new ViewUpdater());
}
But this produces that after reloading data with webview.loadData(),
the contents and the scrollbar are shown on top and just after 150
millisecs everything is scrolled down to the bottom which actually
produce a poor user experience.
Should I open a bug on this ?

[android-developers] Re: Android Physics Engine
I have thrown together a quick example of the APE Physics engine (www.cove.org/ape/) running on Android. As you can see, simulating 30 or so circles results in a solid 15fps, which looks acceptable. The bad news, which I didn't realise before porting it to Android, is APE's lack of simulating rotation of bodies. I.e. if you simulate boxes their x,y positions are calculated but they never rotate. I'm pretty sure I haven't overlooked this feature but i'd be surprised if it wasn't part of the APE engine, maybe someone else could confirm this? Anyway, APE is a lot nicer to use than JBox2D and is on a par with Phys2D for ease of use. I just wish Phys2D performed well on Android then all my problems would be solved! With all the attention this topic has brought I hope we can find a solution in the not-to-distant future... Here's the Eclipse Project: http://www.filedropper.com/apedroid When running 20 initial circles are created, you can create more by clicking the down button. Also you will find lots of commented out code, you can experiment with this if you wish...

Romain Guy points out in this post that the android garbage collector cannot optimize small short lived objects. These are exactly the sort of objects that could be created in a physics engine when it needs to generate dynamic collision constraints. A good solution in this case is to use a pool of constraint objects because they are all going to be the same size/object. The best solution in my mind would be for the compiler to do escape analysis on the objects and stack allocate them when it sees that they will never escape the function. I have been told that the Java byte code can't reference an object on the stack. It's possible that the Dalvik byte code can, I don't know. I don't have a reference for this, but I assume that Dalvik's inability to optimize small short lived object comes from the fact that it uses a mark and sweep GC. On all of my profiling, I see the GC take at least 100ms to run. For a game that means you miss from three to 10 frames of animation and it makes for a pretty noticeable hick up. And I don't think it's my application that is causing the garbage collector to fire. Unless the OpenGL ES calls do some memory allocation, which is entirely possible. I realize that any background task could move to the run queue and take some time away from my engine, it just happens to be the garbage collector most of the time. :) So the result is that the Garbage collector is problematic for me in two ways. First, it's not optimized to deal with the sort of small objects that tend to make for good encapsulations of mathematical types (like Fixed point number classes or Vector or Matrix classes). And secondly it takes a long time to run when it does garbage collect, resulting in dropped frames. -Anton On Apr 2, 3:32 pm, Mariano Kamp mariano.k...@gmail.com wrote: It's maybe a bit off topic, but how do you know that Android's gc is rudimentary?

It's actually not a large number, Views usually don't have many children.
This implementation has nothing to do with the GC. The goal is to
avoid going through method calls to manipulate the group's children.

[android-developers] Re: Android Physics Engine
:) That's great to hear. I know how these things go, so I assumed that it was being worked on. I also understand the complexities of bringing out an NDK. But personally, that's high on my list of desired features. Even one that can't link against any external libraries would be a good start as it would allow for solid physics engines and scene graph engines to be constructed. Not to mention the benefit of C/C++'s lower level type system, which would allow for the construction of fast, memory efficient math classes. :) Thanks for your efforts and support, Anton On Apr 3, 2:29 am, Romain Guy romain...@google.com wrote: We're aware of the shortcomings of the current garbage collector and believe me, it's one of the things we'd really love to see improved as soon as possible :) On Fri, Apr 3, 2009 at 2:04 AM, Mariano Kamp mariano.k...@gmail.com wrote: Anton, thanks.

Romain Guy points out in this post that the android garbage collector cannot optimize small short lived objects. These are exactly the sort of objects that could be created in a physics engine when it needs to generate dynamic collision constraints. A good solution in this case is to use a pool of constraint objects because they are all going to be the same size/object. The best solution in my mind would be for the compiler to do escape analysis on the objects and stack allocate them when it sees that they will never escape the function. I have been told that the Java byte code can't reference an object on the stack. It's possible that the Dalvik byte code can, I don't know. I don't have a reference for this, but I assume that Dalvik's inability to optimize small short lived object comes from the fact that it uses a mark and sweep GC. On all of my profiling, I see the GC take at least 100ms to run. For a game that means you miss from three to 10 frames of animation and it makes for a pretty noticeable hick up. And I don't think it's my application that is causing the garbage collector to fire. Unless the OpenGL ES calls do some memory allocation, which is entirely possible. I realize that any background task could move to the run queue and take some time away from my engine, it just happens to be the garbage collector most of the time. :) So the result is that the Garbage collector is problematic for me in two ways. First, it's not optimized to deal with the sort of small objects that tend to make for good encapsulations of mathematical types (like Fixed point number classes or Vector or Matrix classes). And secondly it takes a long time to run when it does garbage collect, resulting in dropped frames. -Anton On Apr 2, 3:32 pm, Mariano Kamp mariano.k...@gmail.com wrote: It's maybe a bit off topic, but how do you know that Android's gc is rudimentary?

Simpull will also provide good performance for a scene of that nature (all verlet, no joints). At least I believe it will. The point where simpull becomes slow is when a more complex scene is in play with 10s of objects with many joints connecting some of them. Since the engine is all verlet and no rigid body dynamics, joints
[android-developers] ScrollView and Programmatically Scrolling
So, I have a ScrollView with a single TextView inside it. Upon initial startup I set the text of the text view to an internally stored string and try: ScrollView myScroll = (ScrollView) findViewById(R.id.my_scroll_id); myScroll.fullScroll(ScrollView.FOCUS_DOWN); No scrolling happens. (The string is long. I want to show the end of it. Instead, at this point, view remains at the top.) Now I append a few more lines to the text, set the TextView's text to the new text, and perform the same fullScroll(ScrollView.FOCUS_DOWN) function. It now scrolls, but to the end. For example, if the last part of the text is: 5 + 5 = 10 After programmatically scrolling down I see: 5 + I have to manually scroll to see the end. Am I doing something wrong? How can I reliably get the scroll to show the end of the text? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Displaying a Class Variable on Screen
Basically, what I want to do is have the Preview screen showing the
what the camera is currently pointing at, but I would also like to
display the changing X, Y, Z orientation of the phone. Currently I am
able to get a handle to the orientation array and its values and store
it in a Global class variable (I think code should work), but I dont
know how to display changing values on screen. I'm pretty unfamiliar
with UI's, but I want the equivalent of:
-
||
||
||
|Camera Preview |
||
||
||
||
||
||
||
||
| X Coord: + Global.getX();|
| Y Coord: + Global.getY(); |
| Z Coord: + Global.getZ();|
--
Here is my code as it stands right now for setting my Global.X,
Global.Y, Global.Z variables:
public class MyCamera extends Activity{
private Preview preview;
public void capture() {
preview.capture();
}
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
preview = new Preview(this);
Global.setPreview(preview);
setContentView(preview);
SensorManager sens = (SensorManager) getSystemService
(Context.SENSOR_SERVICE);
MySensorListener sensListener = new MySensorListener();
sens.registerListener(sensListener, 1); // no idea what the
second
value is supposed to be, something
//
about a bitmask, help on that would be good too.
}
private class MySensorListener implements SensorListener
{
@Override
public void onAccuracyChanged(int sensor, int accuracy) {
// TODO Auto-generated method stub
}
@Override
public void onSensorChanged(int sensor, float[] values) {
if(sensor == 1)
{
Global.setOrientation(values[0], values[1],
values[2]);
}
}
}
Any help in displaying those numbers at the bottom of the screen would
be a great help.

[android-developers] Why there are 2 instance of same Activityes?
My application has 2 activities. The main activity will create the child activity through startActivityForResult((...). When the child activity needs to exit, it calls setResult(..) and finish(). Child activity will start and exit multiple time upon user selection. The activity are start and exit as expected and onAcitivtyResult(..) also got invoked. However, I found a problem with child activity, when the child activity was created the second time ( Main activity called startActivityForResult(...) upon some user event ), a new instance of child activity was created, but the displayed is the FIRST instance child activity!!! ( so any state in second instance of child activity was not accessible ). The onKey(...) was always go to first instance of child activity. Make things more interesting, the getInstanceCount () returns 3. I have checked the code and no where holds the first instance of child activity which should be garbage collected after finish(). Can someone help out why this happens and how to fix? Thanks, David --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Cupcake Emulator do not mount SD card image
Hello Android team,
Any updates on this issue? Unfortunately remount doesn't help.
My command to launch emulator under Ubuntu:
${ANDROID_ROOT}/out/host/linux-x86/bin/emulator -sysdir $
{ANDROID_ROOT}/out/target/product/generic -kernel ${ANDROID_ROOT}/
prebuilt/android-arm/kernel/kernel-qemu -data ${ANDROID_ROOT}/out/
target/product/generic/userdata.img -skindir ${ANDROID_ROOT}/
development/emulator/skins -skin HVGA-P -sdcard ${ANDROID_ROOT}/
sdcard.img
Actually /sdcard is mounted even if I don't use parameter -sdcard in
the command. Anyway in both cases /sdcard is mounted without writable
access:
d- system system2009-04-03 06:10 sdcard
Music application doesn't see sdcard at all.
Could you please let me know, maybe my launch command is wrong or
perhaps, this is known issue and now under investigation/fixing.
Thanks,
Alexander

[android-developers] Re: I want run my application in background, with Service component
Using a Notification is one way to go about it. The Notification can be linked to an Activity, which gets launched if the user clicks on the Notification. Here's some code, which I think I pulled from some tutorial someplace: CharSequence text = getText(R.string.remote_service_started); // Set the icon, scrolling text and timestamp Notification notification = new Notification(R.drawable.icon, text, System.currentTimeMillis()); // The PendingIntent to launch our activity if the user selects this notification PendingIntent contentIntent = PendingIntent.getActivity(this, 0, new Intent(this, MyActivity.class), 0); // Set the info for the views that show in the notification panel. notification.setLatestEventInfo(this, getText (R.string.remote_service_label), text, contentIntent); // Send the notification. // We use a string id because it is a unique number. We use it later to cancel. mNM.notify(R.string.remote_service_started, notification); Good luck!

[android-developers] Re: Accelerometer/Orientation sensor problem
I have noticed that the speaker output does effect the magnetic
compass reading a bit. Not too surprising, since the speaker uses an
electromagnet. This is probably what is causing the sensor to jitter
around. As for the accelerometers, I would guess that the movement of
the speaker cone itself is what is causing the fluctuations there.
Perhaps its not a problem, but more of a filtering issue, have your
tried any simple averaging on the sensor output?

On my T-Mobile G1 (firmware 1.1, build PLAT-RC33), developing in
SDK1.1r1, I am experiencing a problem where playing sounds causes the
output of the accelerometer and orientation sensors to fluctuate
wildly. The degree of fluctuation is directly proportional to the
volume of the sound being played.
I am using SensorManager per the documentation and examples :
= From my implementation of SensorListener
public void init() {
SensorManager sm = (SensorManager) cx..getSystemService
(Context.SENSOR_SERVICE);
boolean success = sm.registerListener(this,
SensorManager.SENSOR_ORIENTATION,
SensorManager.SENSOR_DELAY_GAME);
// success is true, i.e. no problems acquiring the sensor
}
public void onSensorChanged(int sensor, float[] values) {
if (sensor == SensorManager.SENSOR_ORIENTATION) {
// print/draw/do something with the sensor output in values[]
}}
==
I have tried playing sounds with both SoundPool and MediaPlayer, with
identical results. When a sample is played at max volume the
Orientation sensor outputs will bounce around as much as +-/30
degrees. All axes are affected.
I have tested and confirmed this behaviour for SENSOR_ACCELEROMETER,
SENSOR_ORIENTATION, and SENSOR_ORIENTATION_RAW. Other sensors may
also be impacted, but I haven't tested them.
I have also tested with all of the available sensor sampling rates --
SENSOR_DELAY_FASTEST through SENSOR_DELAY_UI. All result in the same
behavior.
On a random guess I tried muting the microphone with
AudioManager.setMicrophoneMute(true) -- same results.
I thought to try testing this in the Android emulator to see if it
might be hardware-related, but unfortunately there is currently no
accelerometer/orientation sensor support in the emulator.
Is this a known problem? Or am I doing something wrong here?
Thanks
