RE: [android-developers] Re: Scrolling broken in 2.2 ?
Thanks Mike, Yep it's definitely a cross platform framework. At its simplest, I don't think it's too much to expect from a UI to have a scrolling textView within a parent scrollview. I'll delve into the source today and see if I can spot what's messing with the touch events.

RE: [android-developers] Re: Scrolling broken in 2.2 ?
Hi Kumar, I the short term, it would. We're not a consumer application so we do have a reasonable amount of control over the devices that we ultimately deploy on. It's not out of the question for us to say that we don't support 2.2. But obviously it's not in our interests to lock ourselves out of any future android releases.

Re: [android-developers] Re: OpenGL lockups in 2.2
I don't use GLSurfaceView and I am not really sure why anyone would use it for anything other than a demo. It makes your code less portable and takes control away from you. With that said, I do get people with HTC complaining about freezes. So it would seem that it's not a GLSurfaceView problem.

It is very stable on the Droid and I have tested it for about 4months without a single freeze. Interestingly though it never froze on my G1 either. The G1 I have is the ADP1 phone I bought directly from Google. All other HTC phones that I have exhibit the freezing - Evo, Desire and Nexus One (which is also from HTC I believe). Apart from that I tested it for a month on Samsung Moment. There was NO freezing there either. I have been in touch with a Google developer advocate and I have submitted the bug report to his team.

And this freezing happens even when I simply leave the device (HTC Desire) running my app with zero user interaction whatsoever. All the app renders is a scenery with a single animation. No texture changes or geometry changes are taking place in this scenario. But because of the animation, I have to render continuously and this is why I have not used the Render_when_dirty approach. I did notice that when the app freezes, my main UI thread as well as a secondary thread (that talks to a game server) are still running and alive. The main UI thread does register touches until a point and then hangs while the secondary thread stays alive. I tried to send an interrupt() to the GLThread from this secondary thread but that did not help.

I've been chasing this in a couple of my own OpenGL apps for a couple of months as well. It's summed up well in this thread - extremely intermittent, but extremely serious when it does happen. And I'm one of the devs who has pulled an app from the Market as a result. At the moment, I'm provisionally optimistic that I've worked around the issue in my case. Given it's a race condition, I took the approach of maximum thread-safety: I put a whole load of semaphores into my code, added synchronized and volatile modifiers all over the place, that sort of thing. And it seems to have been successful... I can't be sure (because of the intermittency), but I haven't seen it happen for a couple of weeks now. If I had to speculate, I'd say that the problem finally went when I synchronized some code which re-generates geometry within my OpenGL model. I added semaphores to ensure that textures, geometry, and rendering never happened concurrently. There's no way to know that was the end problem, but that SEEMED to be it. If that helps anyone. Just to reiterate, I agree that this is a serious platform-level bug that needs to be fixed by Google. And it has gotten worse since 2.2, although I have (rarely) seen it happen on my G1 running 1.6.

[android-developers] ANR keyDispatchingTimedOut
Hi all, I've got an application with an alarming number of users reporting force closes. I've tested multiple devices numerous times and never had this happen, so it's very difficult to test. Luckily, the new stack trace reporting features seem to give me an idea, but I am not familiar with ANR keyDispatchingTimedOut and Google doesn't seem to be much help. I can debug when I see the error just fine, but I'm not sure what information these stack traces are providing me. Is it just saying where each thread was when the crash occurred? Any help would be greatly appreciated - not just by me, but by a lot of my users!

Hi psyke, You can perform OTA just following the same requirements Android Market performs. VersionCode greater than the one is already installed, signing certificates need to match.package name needs to match... Later after all the bureaucratic things are done you can publish the app in the android market with a greater version code and this will update the second version that was installed as OTA. I've tried my self already...just don;t forget to follow the same requirements from the Android Market.

[android-developers] Re: HttpURLConnection or HttpClient
Yes, we know why. Because Apache's HttpClient (and other closely assoc. classes in the org.apache.http package) is a much better API than Sun's own HttpUrlConnection (and the rest of java.net's Http support). You can do far more work with less code, and it reads much better too. So, for example, HttpClient has helper classes that help you deal with spinning off a worker thread and doing all the waiting on HTTP there; it is designed to work well asynchronously. Sun's HttpUrlConnection has nothing of the sort. That said, you don't get to depart from using java.net entirely. You should still use it for dealing with URIs and URLs. But not for much more.

[android-developers] Droid Losing Values When I Load Image Picker
I have an Android app that is mostly a WebView except for a few things. One of them is uploading pictures. After the user picks an image I get the filepath and pass that along with the webview's url to a new method in a new thread. For some reason, in the onActivityResult method I can't get the value from the webview to know what page they're on. It's null. It works on my HTC Hero (2.1), just not on Droid's.(those are the only users with the problem). I've tried setting a global variable to the url before showing the image picker, but when I try to read it in the onActivityResult method it's just an empty string. On my HTC Hero it still has the value. I need the url so where can I put it where it won't get lost on Droid phones? This is all in an Activity. -- You received this message because you are subscribed to the Google Groups Android Developers group.

RE: [android-developers] ACTION_IMAGE_CAPTURE intent
That is also a part of my problem. I am running in debug mode. I can see the disconnect message in the debug window occur the instant I take the picture. However Activity 3 ( the one that fired the ACTIVITY_IMAGE_CAPTURE gets the result and finishes up nicely. When that task terminates, I get the dreaded FC on the device. It should be noted that after the Disconnect message appears, even though I have several breakpoints set in Task 3 including at the very beginning of the onActivityResult(), none of them is taken, presumably because the debugger has been disconnected? BTW I can tell that Task 3 is finishing properly even though the breakpoints are not being taken. You see one of the last things that Task 3 does in it's onPause() is to save the path to the new picture in the database. When I restart after the FC, the proper image is always present. It is as if something goes haywire and even causes the debugger to get disconnected. I guess that is what the Disconnect from local host means Again I point out that I can do iterations all day as long as I do not use the camera feature. However the instant that I use the Camera feature the App runs into trouble as soon as the Shutter is clicked on the phone.

So yes, you did make it more confusing instead of less. You are seriously confused indeed. Thanks to your own careless wording, yes. But that was and still is my point. You are making it more confusing, not less, even now, though this latest post of yours is a considerable improvement. Tools r8 will ship with ADT 8.0.0. The version that comes after will be Tools r9 with ADT 9.0.0, and then r10 and ADT 10.0.0, etc... Since both are meant to work together, it seems to me like it's a pretty straight forward versioning scheme. Your wording this time does make it more clear, yes. But what remains not at all straight forward is what you think to achieve by numbering the Tools in an rn format, where n is an integer, but numbering the things -in- the Tools with n.0.0. What will you ever use the other two digits for, if new versions are only released with an entire new Tools release, which is always numbered with an integer? Or have you simply forgotten to use the terms minor revision number and major revision number? Did you really mean to say the the - major- revision number of each tool will match the revision number of the entire Tools package? When we release r8 we will clearly explain this new scheme so that users know what to expect. That will be a welcome improvement, I am sure. I fail to see how it's more confusing that previous releases of r7 with ADT 0.9.8, r6 with ADT 0.9.7, etc... where the ADT version was completely unrelated to the SDK tools revision number. It is more confusing because in the earlier scheme, we knew it was unrelated. But with the incomplete and poorly worded explanations you gave to date of the new scheme, it was clear that there was a relationship, but with the apparently superfluous extra digits, it was not clear whether that relation was really meant to be identity, forever kept in lockstep. For that matter, are they sharing the same version number, or the same API level? The version number is 2.2, the API level 8. Based on what you have said so far, it sounds like you are using the API level as the version number for the tools, which is not the same as making all tools and plug-ins share the same version number. What are you talking about? Tools don't have an API level, so there's certainly none to share between the SDK Tools and ADT, and, obviously, the API level for the platform has *nothing* to do with revision number for the tools! No, it is not obvious that it has -nothing- to do with it. Especially not when both happen to be '8'. That could be coincidence (as you now confirm that it is), but without the further information you now supply, we had no way of -knowing' that. For all we knew, you could have decided that in the future, you would release new versions of the Tools only with new version of the API also. That is hardly more arbitrary than deciding that you will release new versions of any tool only with a new version of the whole Tools package. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Choosing background for Live Wallpaper.
Here's an update on where I am with this. I have to say it's pretty
hackish and I'm not proud of it but it works, sorta.
I created a Preference in my Settings dialog to choose the background. From
the callback I call 'startActivityForResult' with
the Intent.ACTION_SET_WALLPAPER.
This launches the default wallpaper chooser allowing the user to select
whatever they want for the wallpaper, with the caveat that the Live
Wallpapers shows up also, which I don't want.
In the 'onActivityResult' callback i check for RESUT_OK and do the
following:
- Get an instance of the wallpaper manager.
- Get the drawable from it.
- Turn it into a BitmapDrawable and write it to a private file (for
persistence) also storing it in a variable.
- During my regular draw function I draw that to the canvas and then draw my
overlay.
On startup of my wallpaper I check if the file exists. If it does then I
read it into my bitmap variable and continue as normal.
If it doesn't exist then I get the wallpaper drawable and do the same things
as above (file, variable).
This works wonderfully for most situations. But it breaks horribly when the
user selects a live wallpaper in my settings dialog.
In the Emulator things keep working. My 'onActivityResult' gets a
RESULT_CANCEL event and nothing changes for me. I'm able to back out of the
settings screen and continue no problem.
On my device however (HTC Desire w/ 2.1) it crashes the phone when I select
a live wallpaper from within my settings.
Why the discrepancy between the two? The only difference that I can tell
between the two is that my device has more live wallpapers installed.
What can I do?
Can I detect that a live wallpaper was selected and handle it differently?
I didn't debug the app on my phone so I don't know exactly what was
happening.
My exact call to start the activity looks like this:
private void startWallpaper() {
final Intent pickWallpaper = new Intent(Intent.ACTION_SET_WALLPAPER);
startActivityForResult(Intent.createChooser(pickWallpaper,
getString(R.string.rain_background)),REQUEST_PICK_BACKGROUND);
}
The Live wallpaper chooser has two intents; ACTION_SET_WALLPAPER
and ACTION_LIVE_WALLPAPER_CHOOSER. Is there a way, when I call
Intent.createChooser to filter out based on an intent even though an item
matches another intent?
If not then Google seriously needs to give us this.
Not sure what to do next.
I'm so close I can feel it.

Hello all,
I've asked this question twice already but it didn't seem to get
posted. I don't know if it just takes a while for the moderators to

I'm writing a live wallpaper that creates an effect over a
background. I want the user to be able to choose the background from
any of the system wallpapers and camera photos. What I would like is
for the user to be able to press a button in the Settings menu, have
the list of options show up just like setting the wallpaper from the
home screen, minus the Live Wallpapers options. Once the user
navigates the choices and picks an actually image I would load it to
my canvas.
How do I do this?
I can't find an API anywhere for getting a list of wallpapers.
I've been able to come up with a list of wallpaper providers using
Intents. I then get a list of live wallpaper providers also using
Intents and remove those from my first list. The gives me a list of
wallpaper providers that are not live.
Now what? Are there other ways to do this that I'm missing?
Please help.

[android-developers] how do I load an image for a softkeyboard
Hi,
I am trying to develop a softkeyboard, which uses and image, senses
the onTouch events, and sends characters to the input stream.
So I have created the essentials of the keyboard and I want to load an
image. Here's what I do:
public class mekb extends InputMethodService implements
View.OnTouchListener {
@Override public void onCreate() {
super.onCreate();
}
@Override public View onCreateInputView() {
return (KeyboardView)
getLayoutInflater().inflate(R.layout.main, null);
}
}
And this is what I have in my layout/main.xml (essentially an image
view on the bottom of the screen)
?xml version=1.0 encoding=utf-8?
RelativeLayout
android:id=@+id/widget79
android:layout_width=fill_parent
android:layout_height=fill_parent
xmlns:android=http://schemas.android.com/apk/res/android;
ImageView
android:id=@+id/widget93
android:layout_width=wrap_content
android:layout_height=200px
android:src=@drawable/english_uppercase
android:layout_alignParentBottom=true
android:layout_alignParentLeft=true
/ImageView
/RelativeLayout
This loads and let me select the softkeyboard, but errors and stops
when I invoke the keyboard.
Is this how to load an image and return it in onCreateInputView()?
@Override public View onCreateInputView() {
return (KeyboardView)
getLayoutInflater().inflate(R.layout.main, null);
}
Any help, hint or pointer is much appreciated.

[android-developers] Re: Any way to animate a 2D Game Smooth without OpenGL ?
OK.. so the important point in the two-threads theory is that the work IS done concurrently. The GameThread does all the calcs for the next frame WHILE the render thread is rendering the previous frame. So that you don't modify game objects while the render thread is rendering, you separate the concept of a game object from a render object. So you basically have two objects representing things in your game world. One is responsible to maintaining the state of the relevant game element, the other is JUST responsible for drawing. So in your case you would split your current object (that has the update and draw methods) into two objects. The GameThread updates the state-based object (the one with the update method) and the render thread just draws the render object. When the GameThread has updated all objects for the next frame, it waits until the previous frame has completed, then locks the render thread while it updates all the renderable objects. So basically you loop through all the game objects and set the x,y coordinates etc of the corresponding render object. This means you are only pausing the render thread for as long as it takes to loop through the objects and essentially just copy a few floats across. This should be super quick. In terms of storage.. that is, how do you maintain a List of objects (in both the render thread and game thread), again I took a lot from the Replica Island example. Chris Pruett has a thing called a FixedSizeArray which he uses to avoid memory allocations at run time. I didn't end up using this and wrote my own, but basically the idea is that you allocate an array up front, and never change it's size. I just have a global variable which tells me the MAX_SPRITES I will ever have (currently at 300 I think).. so at game launch I create an array of size 300. My implementation is wrapped in a bunch of logic so that I can use it like a list (ie add/remove/delete etc) but actually all it's doing is setting indexes in the fixed size array (or setting them to null to remove). I then have the concept of an iterator which knows how to loop over the array (avoiding nulls etc), and can be created in a ThreadLocal to allow concurrent access from multiple threads.

Or how you store and iterate your gameObjects. In My case every GameObject, like a Missle or Enemy has update(long difftime) and draw(Canvas c) method implemented. In the game thread the thread iterates over all objects and updates them (via update) and after that the Thread iterates over all Gameobjects an calls the draw method. Basically i don't see the big advantage to separate those to Methods in 2 Threads- because at the end draw() is called after update() - (while true)- if you have 2 threads you kind of loop over 2 threads. because 1 is started, finished, stops, starts thread 2, finishes, starts thread 1 I you can spare some time i would be very thankful to maybe have a Skype or TeamSpeak Chat with you =) On 15 Sep., 15:34, Jason jason.poli...@gmail.com wrote: Hi Andreas, Sorry to jump in late, but I thought I'd share my experiences with non- opengl on Android. I have a game engine which uses both open gl and the canvas system depending on the device capabilities (some devices, like HTC Tattoo have software implementations of opengl which is actually slower than canvas). I get reasonable performance from the canvas api, but the important thing is that the bottle-neck has always been draw speed and nothing else. I pretty much followed the replica island approach whereby I have two threads, one which just draws and the other where all the game calcs are done. My game thread routinely outperforms my render thread, but I am drawing quite a lot so this may not be everyone's experience. I'd say you do have a slight architectural flaw in that (it appears) that your game logic is being computed in the same thread as the rendering. This means that the render thread has to wait each frame for the game to update state. It's much better to separate these two. Have your game logic updated in a separate thread, then just notify the render thread when it's time to draw (you can do this by sending a message to your surface view using a Handler and then invalidating the canvas). Basically what I do is this: I have a separation of game objects, and renderable objects. A game object is the real representation of the in-game element (eg the player). The renderable object is simple a set of x,y coords, plus scale, rotation etc and a reference to the image that represents the sprite (I have some more logic to include sprite animations
[android-developers] Can we customize spinner dialog
When we select spinner it shows a display of items which almost the device screen size Can we minimize its width or height, I think this question was already posted by some one.

Re: [android-developers] Find the location in Android Map
I thought you want to to display a mark on a map from the latitude and longitude a user entered in two text fields. But I don't understand if you want to display that on a MapActivity in your app or in another app. - I want to display that on a MapActivity in my app. Not in another activity. One thing that may help is if you try to display a mark on a map foir a given latitude and longitude instead of from a user's input. Have you been able to do that successfully? - Yes, I tried with that also. Firstly, I entered hardcore values in the app of latitude and longitude. Its working. But everytime we have to change it for different locations. Thats why I put EditText and button so user can enter its own latitude and longitude. ~Dhr.

Re: [android-developers] Can we customize spinner dialog
Yes, You can do it. While setting the dropdownviewresource for the adapter of your spinner, define your own xml layout instead of the android's inbuilt resource xml. Your xml can simply have a textview with your required layout parameters. -Shashidhar On Thu, Sep 16, 2010 at 9:55 AM, Karteek N kartee...@gmail.com wrote: When we select spinner it shows a display of items which almost the device screen size Can we minimize its width or height, I think this question was already posted by some one.

[android-developers] How to do this correctly in SQLite?
Hi,
I want to insert a String value call temp but I don't seems to get it
working for the INSERT INTO statement.
Anything wrong with the code?
This is the initialization to create table and insert some default
values into the table if the database doesn't exist.
Many Thanks.
---code---
@Override
public void onCreate(SQLiteDatabase db) {
db.execSQL(CREATE TABLE + TABLE_NAME + ( + _ID
+ INTEGER PRIMARY KEY AUTOINCREMENT, + FIELD1 +
VARCHAR(1), + FIELD2
+ TEXT, + FIELD3 + TEXT, + FIELD4 + TEXT, +
FIELD5 + TEXT););
String tmp = temp;
db.execSQL(INSERT INTO + TABLE_NAME + VALUES (0 'A',
'Hello', '', + temp + , ''););
}
