[android-developers] Re: Service not able to download network data while in standby
As the others have said, use the AlarmManager. A couple of other things which may be of use to you if your process takes a long time Use the PowerManager to get and aquire a WakeLock - this will stop the phone from going to sleep whilst you're doing stuff. Use the WifiManager to get and aquire a WifiLock - this will keep the wireless connected whilst you're doing stuff. Don't forget to release the WakeLock and WifiLock when you're done.

// Where the file is going to go
FileOutputStream outStream= new FileOutputStream(sdcard/file.mp3);

//Write the buffered chunk to the file
outStream.write(bytes, 0, readBytes);
readBytes = file.read(bytes);

inStream.close();
outStream.close();
should do it. I've typed that more or less by hand so it's missing

[android-developers] Re: New app update force closes immediately on startup!
I was under the impression that if you have an app installed without protection and then update to a version with protection you get force- closes. I have no idea if it's been confirmed though, sorry. On Mar 31, 7:43 pm, rcs rsar...@gmail.com wrote: Hello all... This morning, we updated our app on AM; this was our first update since release of Android 1.1. In testing, on the emulator and with the signed .apk installed on our handsets, everything appeared to be working fine; however, we uploaded to AM, selected the new CopyProtection option, and published. Wertago disappeared for about 30 minutes, and as soon as it reappeared, we downloaded, installed, and started. Immediately upon starting, we got a force close and were never able to get the app started at all. We've seen some discussions about similar app behavior experienced by other developers, and there was mention of likely bugs in AM or in the Copy Protection scheme. Has this been confirmed by Google, is there any communication from them about a coming fix, or anything like that? Here's a little detail about what we gather from the logcat output. Our app appears to fail upon attempting to open/create the database; the relevant line is: tmpDatabase = instance.openOrCreateDatabase(SEARCH_DATABASE_NAME, Context.MODE_PRIVATE, null); which throws the sqlite3_open_v2 error.

[android-developers] Re: Save an mp3 from a remote site
Good point, I forgot about the MediaScanner.
One thing to note about using ACTION_VIEW is although you get the nice
mediaplayer UI it doesn't keep playing when you change Activities e.g.
go back to the home screen.
On Mar 31, 3:57 pm, Jean-Baptiste Queru j...@android.com wrote:
No problem playing an MP3 from the SD card. You should be able to
ACTION_VIEW the file:/// URI directly, or invoke the media scanner on
it and ACTION_VIEW the resulting content:// URI (added bonus for the
second method is that the file will immediately show up in the music
player as well).

I was thinking that I could compose an email that the user could send to himself with a link in it like: content://mycontentprovider/databackup/the data, possibly in a delimited format (comma-separated) And when the user would click the link it would pull up my content provider that would take all the data from the link and restore it into my database. Alternate idea: save the database file to another machine or email, but I wouldn't know how to go about doing this. Can I make my application attach the database to an email that could be imported?

[android-developers] Re: Passing ArrayList across actvities
Assuming MyList is an object you'll need to make it implement
Parcelable and Serializable
There are then 2 functions that you'll need to set up
this is used to re-create the object at it's destination:
public static final Parcelable.CreatorMyList CREATOR = new
Parcelable.CreatorMyList() {
public MyList createFromParcel(Parcel in) {
MyList foo = new MyList();
foo.bar = in.readString();
return foo;
}
public MyList[] newArray(int size) {
return new MyList[size];
}
};
and this is used to actually parcel the object in the first place
public void writeToParcel(Parcel arg0, int arg1) {
arg0.writeString(this.bar);
}
I'm pretty sure you need to put items into the parcel in the same
order that you get them out, but don't quote me on that.

[android-developers] Re: help......i am a Beginners
You need to make sure that there is text in the TextEdits before
calling parseDouble because it will throw an exception otherwise.
Something like:
String heightText = fieldheight.getText().toString();
if( heightText != null !heightText.equals()){
// do stuff here
}
should work.

[android-developers] Re: MyLocationOverlay causing crash in 1.6 (Donut)
Well if they will install a non-released version of the OS then that's
to be expected.

Recently, two independent users with 1.6 (Donut) on their phones have
informed me that my app crashes after it enters a MapView, just as
soon as MyLocationOverlay obtains its first location fix. I have seen
it do so with one of them, in fact. However, when I asked for a
logcat, what they sent me seems to indicate the crash originated from
an uncaught ClassCastException thrown from within MyLocationOverlay
itself, not from my code. Worse, I tried running this on the 1.6
emulator and couldn't make it crash (I don't have 1.6 on my actual
phone yet), so I am completely lost with this and unsure if it's
something odd they were doing on their phones or something I will have
to worry about when 1.6 gets rolled out to more people.
One user has tried uninstalling/reinstalling the app numerous times,
as well as disabling Dalvik-Cache, all to no avail. This app works
perfectly on both 1.1 and 1.5 phones. I also tried recompiling the
app explicitly using the 1.6 SDK, and it still crashed (as per the
user I talked to). Is there anything I would need to consider with
regards to MyLocationOverlay when upgrading to 1.6?
Thanks in advance!

Thousands of games for Microsoft Mobile Junk and still no great games for Android. Worst. Many Android developers will go to WinMo for XNA. Many games will be easily ported from Xbox Arcade too. And we will be wasting time, wondering, how to get 25fps from Canvas or OpenGL. Without sound. Now, I think, is the time to do something with that. Android really needs something like XNA, to allow us producing games without all that technic stuff like OpenGL, game loops with managing threads, times, buffers, right pixel format settings and others.

[android-developers] Splintering of the Market
Having just received an e-mail from the Google about up-coming changes to the market I was wondering what other people thought of it. The bit that I don't like the sound of is: First, we have added the ability to target applications by carrier in all countries. For example, if you are showing your app in the United States, you can now choose among Sprint, T-Mobile, and Verizon Wireless. The deliberate splintering of the market by allowing carriers to essentially have own market with their own exclusive apps is a terrible idea in my opinion. It's going to make this confusing and annoying for users who see their friends using software on an identical phone and operating system but are unable to use it themselves. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

Thanks for the info, Wouldn't this Finger 1 up: MotionEvent ACTION_POINTER_1_UP with one pointer, whose ID is 1. need to be ID of 0? Or am I mis-understanding the purpose of the UP action? On Oct 27, 4:45 pm, Dianne Hackborn hack...@android.com wrote: It's basically just some new APIs on MotionEvent: http://developer.android.com/reference/android/view/MotionEvent.html http://developer.android.com/reference/android/view/MotionEvent.htmlHmmm and I'm not sure why, but in the doc all of those new APIs are in gray, so they should be easy to see. :) Or here is the API diff report: http://developer.android.com/sdk/api_diff/5/changes.html http://developer.android.com/sdk/api_diff/5/changes.htmlI see that I didn't get around to writing documentation in MotionEvent on the way multi-touch works; sorry about that. Basically there are new actions that tell you when additional fingers go down and up, and each MotionEvent you receive allows you to query for the number of pointers in the event as well as the x, y, size, and pressure of each of those points (and the historical data for all those points as well if you want to collect all data since the last motion event you received). So it should be pretty straight-forward. The main thing to watch out for is the difference between the index in the current event for a pointer's data vs. the pointer ID for that pointer: http://developer.android.com/reference/android/view/MotionEvent.html#... http://developer.android.com/reference/android/view/MotionEvent.html#...The pointer ID allows you to keep track of the individual fingers across multiple motion events. For example, if the user touches finger 1, then finger 2, then releases 1, then touches 1 again, you would see: Finger 1 down: MotionEvent ACTION_DOWN with one pointer, whose ID is 0. Finger 2 down: MotionEvent ACTION_POINTER_2_DOWN with two pointers, whose IDs are 0 and 1. Finger 1 up: MotionEvent ACTION_POINTER_1_UP with one pointer, whose ID is 1. Finger 1 down: MotionEvent ACTION_POINTER_1_DOWN with two pointers, whose IDs are 0 and 1. Finger 1 up: MotionEvent ACTION_POINTER_1_UP with one pointer, whose ID is 1. Finger 2 up: MotionEvent ACTION_UP with one pointer, whose ID is 1. (And inspite of what the update documentation says, the API allows for an arbitrary number of fingers, not just 3. I just happened to define convenience constants for the first 3 finger down/up actions, but given their weird naming as seen above and the finger ID mask is actually 255, it is perhaps best just to ignore those constants. :p) On Tue, Oct 27, 2009 at 9:29 AM, Streets Of Boston flyingdutc...@gmail.comwrote: Kind-a burried inside the blog-post on developer.android.com (http:// developer.android.com/sdk/android-2.0-highlights.html), i saw that multi-touch is now supported: Android virtual keyboard •An improved keyboard layout to makes it easier to hit the correct characters and improve typing speed. •The ***framework's multi-touch support*** ensures that key presses aren't missed while typing rapidly with two fingers. •A smarter dictionary learns from word usage and automatically includes contact names as suggestions.

[android-developers] Re: Android 2.0
For what it's worth, I believe the biggest causes of apps breaking on the newer devices are them having trouble with the new screen densities / sizes, and them using private APIs. We got the screen support out earlier in 1.6 and have been trying to beat that drum to get people to start to address that, since that is one of the biggest impacts on them. It's also a tedious and boring task - not your fault obviously. That doesn't mean it'll get done any quicker though ;) There are certainly some specific kinds of apps where running against specific hardware is much more useful (open gl and camera are the two main ones that I would think about), but as far as dealing with different platform versions, the platform is the platform, and whether you run it in the emulator or on one device or another it behaves the same. Are you allowed to say anything about Droid's openGl version?

[android-developers] Re: Screen Sizes with 1.5, 1.6 and 2.0
It seems like the links in the reference are broken 1.6 lets you specify which screen sizes you support and what to do in each case, so you'll be ok compiling against that. I'd still download the 2.0 and create an emulator image running that at the droid screen- resolution. By default android will just upscale your application, I think.

@Kevin You might want to look at the rokon engine a good basis for doing a 2D game as it takes care of pretty much all the rendering work. @Mario I was hoping to avoid using the build number as that is a temporary fix only. @Ralf The accepted work around for the touch slow down issue is to put a Thread.sleep() in the event handler to stop it getting spammed with events. A delay for 16ms seems to work well for most people.

I would love to develop some side scroller/top down tile based games with sprites, and yet I can't seem to find a good place to start. I saw this one google IO presentation, forget the guys name, that said on each iteration you pass the time delta and always keep it time based (as opposed to frame based I assume) and that while some basic puzzle games can get away with using a canvas (GLSurfaceView??), most games would require open GL to some extent. As well, I am interesting in knowing how to play background music and yet still play multiple sound FX on time with no delay so that when something collides, a sound plays at that exact moment, not a 1/2 second later. Is there any good resources on this? I don't need to make a perfect game my first time out.. just something to play with. I am also curious with regards to the 24MB ram limit per app, how you make larger levels without any potential delay in the game play. As the game scrolls one way or another (especially a top down with a large map), how do you avoid the GC while loading in new tiles for the map? One thought I had was the game goes online to get a map, storing it on the SD card, so as to avoid using precious on-board user/app ram. I've read from various posts from some of you about how you try to load everything in first, don't create any objects during the game loop, etc, but it seems games on the iPhone are quite impressive with smooth framerates, and I am aware that we're a bit limited as of yet on Android, especially with regards to the NDK layer being able to update video/audio buffers (or maybe I have that wrong?). As well, how important will a JIT play into games being better perofmant when we finally get a JIT (and anyone know when that might be by chance?). Along the same lines, can someone correct me regarding the info I think I have pulled from various posts about video/audio buffers/hardware access in the NDK layer? Do most of these opengl/better games require NDK C code to work well? Or are most of these games using pure Java code? I am thinking like Robert Green's game, and the air plane landing game (which seems like there are 5 or more on the market now of almost identical game..someone lifted the original code I guess?). Are they using NDK and thus I gotta get into that lower level to make a viable game... or is it possible to do a decent side scroll/top scroller game without going to that level. In a nutshell, I don't have the talent to build high end games like Assassins Creed, NBA hoops, etc form iPhone. I am not that skilled. However, I would love to learn, but think starting with a basic side scroller game with tiles and animted sprites is a great place to start. So, any references/urls/tutorials anyone can point to with some details on the whole game loop, how to scroll/draw tiles, update animations of sprites so they look fluid as they move, and how to mix music/sounds in there?

[android-developers] Re: Can i use real number? for example 0.5
dp is a way of keeping things consistent over varying screen densities. If you don't want to do that you could specify one of these: px Pixels - corresponds to actual pixels on the screen. in Inches - based on the physical size of the screen. mm Millimeters - based on the physical size of the screen. pt Points - 1/72 of an inch based on the physical size of the screen. dp Density-independent Pixels - an abstract unit that is based on the physical density of the screen. These units are relative to a 160 dpi screen, so one dp is one pixel on a 160 dpi screen. The ratio of dp-to- pixel will change with the screen density, but not necessarily in direct proportion. Note: The compiler accepts both dip and dp, though dp is more consistent with sp. sp Scale-independent Pixels - this is like the dp unit, but it is also scaled by the user's font size preference. It is recommend you use this unit when specifying font sizes, so they will be adjusted for both the screen density and user's preference On Feb 11, 6:37 am, taehun zzang taehun...@gmail.com wrote: I want to use 0.5, but don't work. android:layout_marginTop=0.5dp can I use real number or not?

[android-developers] Re: Alarms, Receivers and Wakelocks...oh my!
The code I'm using has a static method in the service I'm about to
start that creates a wake lock that I then reference from within the
started service.
I took it from a discussion about WakeLocks in here and it seems to
work.
private static PowerManager.WakeLock _wakeLock = null;
synchronized public static PowerManager.WakeLock getLock(Context
context) {
if (_wakeLock == null) {
//Log.i(DownloadService, Creating wakeLock);
PowerManager mgr=(PowerManager)context.getSystemService
(Context.POWER_SERVICE);
_wakeLock=mgr.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK,
my worker wake lock);
_wakeLock.setReferenceCounted(false);
}
return(_wakeLock);
}

My understanding is that to properly hold a device awake after an
alarm is triggered you have to aquire a WakeLock in the onReceive()
event, call a Service, then perform the work in the Service, releasing
the lock within the Service when complete.
http://groups.google.com/group/android-developers/browse_thread/threa...
http://www.mail-archive.com/android-developers@googlegroups.com/msg66...
This pattern can also be found in the CommonWare Advanced Android
Development book.
I tried this, but I found that the AlarmManager, when calling the
BroadcastReceiver, runs on a separate PID than the IntentService when
started from the BroadcastReceiver's onReceive() event. This makes
the static variable on the lock manager.
I tried this, and my logs indicate that the PID is definately not the
same, and my understanding is that the DalikVM instances act like a
standard JVM, whereby objects and variables are no shared between
JVMs.
Furthermore, since the WakeLock is not serializable, there is really
no way to pass the reference to the lock via an extra in the Intent.
Has anyone else seen this pattern work or fail? I have an example
project (with compiled APK) if you'd like to test it yourself, where
shall I post this? I have tested this on the emulator on versions 1.6
and 2.0.

[android-developers] Re: Forward search queries to one single activity that handles search
Take a look at the SearchManager stuff:
http://developer.android.com/reference/android/app/SearchManager.html
From what I can see you only want one activity that responds to the
search, the others need to be able to initiate (I think) what would be
a 'local search'
When you start a search the system it always going to create an
instance of those classes which have the filter so they can process
they search intent.

Your assumption is partly right.
I want all activities to accept search queries (via the search button

search (via a web server) and display the results.
The problem is now, to make all activities accept search queries.
Therefor I have to add the intent filter to all activities,
otherwise pressing the search button will only show up the default
Google Search, but not my custom search.
But having the intent filter in each activity causes to create a new
instance (at least onCreate() is called) of that activity, whenever I
enter a String and start the search. And that is what I'd like to
avoid.
My goal is to have all activities accept search input (meaning
pressing the search button opens up the search box), but then as soon
as the search gets started it should be handled by the one single
search activity.
I hope that helps to better understand my problem.

While I will not argue that we need to be better about getting SDKs out earlier, for developers the changes in 2.1 are really not that significant.

If it helps, 2.0.1 is actually a branch off of the 2.1 development with various fixes from 2.0 that we desired for a maintenance release for Droid, and the new APIs hidden because they weren't quite ready to be supported yet.

[android-developers] Re: HTC Hero (and others) and 100% Awake Time
Maybe your app running it coincidently causing a problem with something in the SenseUI widgets - they do fancy stuff with messages etc don't they? On Jan 9, 3:32 am, Doug dougforp...@gmail.com wrote: Hello, I have an app that works on any version of Android from 1.5 up - this makes it compatible with the HTC Hero. Problem is, the Hero stays awake 100% of the time when its running. For some strange reason (and this has only been reported to me by Hero users, although other devices could be having the same problem) the Hero will just *not* go to sleep when my app is running. The Settings - About Phone - Status - Awake Time always shows the same value as Up Time when my app is running. The definition of this value seems to be What percentage of the uptime has the phone NOT been in deep-sleep. I've done a decent amount of searching on this problem. I see plenty of evidence that its a known issue with many apps (even some of HTC's own components) and that its been at least partially addressed by a firmware update late last year, but there doesn't appear to be any documentation as to what actually causes the problem. So I spent a considerable amount of time analyzing my app and reworking large chunks of code that just might have been causing problems. No luck. A bit about the app: * It is set up to run on phone boot * It registers its own ContentProvider * It has receivers for Phone status (calls), Data connectivity, Bluetooth availability, incoming SMS messages, and the apps own broadcasts * It has a service component that is started with the startService (Intent) call. The service shuts itself down when it's completed its work * It uses both Handler messages, and Broadcast Intents to communicate events of interest. * The service will spawn one or two worker threads to do its bidding, when the workers are done they will stop. * The app sets alarms to be woken up periodically (default once per hour) so it can connect to a server to check for updated data. * Because the background worker threads use HTTP to connect to servers, they are protected by WakeLocks (a wake-lock is acquired when the task begins, and is released when the task completes) * There is not a single sleep anywhere in the code (I've read elsewhere that sleeping is disapproved of) * I have logging from logcat showing that the background threads, service and WakeLocks are correctly releasing themselves and stopping * Spare Parts shows that the Partial Wake usage of my app is actually very low (sometimes doesn't even register on the list) From a previous post by Diane: When no wake locks are held, the CPU will not run at all, and time has effectively stopped for most scheduling (that is scheduling based on SystemClock.uptimeMillis(), which is what most things like Handler and Java timeouts use). So, given that my app isn't holding any WakeLocks, I don't understand what could be causing the phone to remain awake (screen off) when my app is not doing anything. Unless there is a WakeLock being held somewhere... that the mere startup of my app causes to be 'acquired'. If anyone has any ideas - feel free to voice them. If anyone can comment on whether they have encountered (and resolved) this problem I'd be grateful to hear from you too.

100 is a low estimate but it's around that point that the frame-rate seems to get into the sub 30's.

Use texture atlases for smaller sprites - To avoid state changes in OpenGL Use VBOs Avoid textures with alpha channels on slower devices. Don't scale or rotate your sprites on slower devices.

[android-developers] ListView display problem
I have a list activity which is doing something very strange when you select items. It doesn't seem to be de-selecting old items if you click on a different one. if you use the trackball it seems to select every other item and then swap the selection as you move up and down. I'm not doing anything special just getListView().setChoiceMode(ListView.CHOICE_MODE_NONE); setListAdapter(new LevelAdapter(this)); getListView.setOnItemClickListener(this); the LevelAdapter inflates a view from XML but I don't see why that would be causing issues. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

You're overwriting the previous line each time you touch so the

your previous strokes.
Take a look at the Path class, this provides an easy way of chaining

[android-developers] Re: sound effect using SoundPool
Apologies for necro-posting but I thought I might as well post the fix
I found for the non-looping sounds
in the code TJerkW posted.
Essentially setLoop() takes the Id of the instance of the sound that
is being played not the Id of the loaded sound.
So it should look something like this:
public int playLoop(int resid) {
int soundId=soundPoolMap.get(resid);
int instanceId = soundPool.play(soundId, volume,
volume, 1, 0, 1f);
soundPool.setLoop(instanceId, -1);
return instanceId;
}
I'm returning the Id so that I can stop it later when I want to.

[android-developers] Re: Sprite imaging for 2D game programming
Take a look at the Canvas method drawBitmap() http://developer.android.com/reference/android/graphics/Canvas.html#drawBitmap(android.graphics.Bitmap,%20android.graphics.Rect,%20android.graphics.Rect,%20android.graphics.Paint) with that one you can specify the bitmap (the sprite sheet), the subset of the bitmap you want to display (the current frame) and the destination on the screen. To make it animate you'll want to keep track of the amount of time you've displayed the current frame, you can do this by updating a counter by the amount of time that passes between each update call e.g. when you update model position etc. When it exceeds whatever you've decided to be your frame-rate you change the current frame and reset the timer.

To get the accelerometer readings you'll need to implement a listener, have a look at the SensorManager.
