[android-developers] Hardware accelerated Canvas.drawPicture support (or recommended alternatives)
I am hoping to use the svg-android project to implement a dynamic SVG viewer for files with fairly large amounts of detail. My initial smoke tests are promising as the SVG files I am using are rendered correctly however performance is poor without any sophisticated drawing optimizations. I believe this is due to the usage of Canvas.drawPicture (svg-android translates the SVG document structure into a single Picture), preventing hardware acceleration on supporting devices and possibly being implemented without efficient trimming of areas outside the clip bounds. Before I begin significant or fundamental optimization however, I'd like to confirm a few things about Android's rendering pipeline (both recent and older versions). Hopefully this will allow me to utilize existing research already conducted by the Android team or other community developers. Specifically: 1. What performance gotchas may exist with simply constructing my own macro notion of a Picture and replaying the raw Canvas operations on draw? That is, define a very simple op-code interpreted language in which I can represent a Picture and simply execute it on draw myself much like how I assume Picture is natively implemented. Will this alone be sufficient to permit hardware acceleration? I'm assuming no given that Android developers would have implemented drawPicture on the hardware accelerated path if it were this simple, but I'd like to understand why and if there may be anything I can do to mitigate the issues in my specific case. 2. I believe an asynchronous tiling bitmap layer may be an appropriate solution where sections of the SVG are dynamically rendered to off- screen bitmaps and blitted on screen. A separate renderer thread would be used to manage writing to a cache of off-screen bitmaps. Can hardware acceleration help in some way with this off-screen rendering or would it merely kick in with improved performance when blitting those tiles to screen? If no, I may be able to avoid the issues with #1 entirely since hardware acceleration wasn't going to speed up the off-screen rendering anyway. 3. What is the runtime nature of attempting to draw paths and primitives (lines, rects, etc) that are entirely outside the canvas' clipped bounds? Is it necessary or appropriate for me to call Canvas.quickReject myself or can I rely on this rejection happening at a lower level automatically? Can I expect that it behaves consistently when drawing a Picture versus drawing a Path? This is especially important if I implement a tiling renderer as per #2 where a large number of draw requests will be made for the full graphic to render into discrete sections. If Canvas cannot reasonably minimize cycles for this case I will likely need to implement my own culling optimizations. If anyone has other suggestions for things I didn't consider please feel free to let me know. I'm hoping to drive toward an elegant and efficient solution that works optimally on newer hardware but with acceptable performance on other devices. -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Hardware accelerated Canvas.drawPicture support (or recommended alternatives)
Thanks for the quick reply. Given your last comment about rasterization of Path, I think an appropriate option is to just disregard hardware acceleration for most of what I'm doing and render the full graphic into a set of tiles. The hardware renderer can optimize the last mile step for me by efficiently copying and scaling my tiled bitmaps onto the display. I will also do some performance benchmarks to get a sense for how expensive drawing the Picture is versus culling only the portion of the full graphic I need. Hopefully it's negligible.

What performance gotchas may exist with simply constructing my own macro notion of a Picture and replaying the raw Canvas operations on draw? Not much really. The UI toolkit has its own equivalent of Picture called DisplayList. If you render a View with on draw() the toolkit builds such a display list and keeps it until the next invalidate. 3.

It will happen automatically but you can save a bit of work by doing it yourself early on. If anyone has other suggestions for things I didn't consider please feel free to let me know. Just one: path rendering can be very inefficient on the GPU. Currently only rectangles and lines are implement natively, all other types of shapes are rasterized with the software renderer into a GL texture. If your paths change often, performance will be pretty bad.

[android-developers] Android 4.0 sensor emulation setup questions
I believe I have the sensor emulation support working properly (I can connect to port 1968 locally and it appears to be connecting to the phone) but it is unclear to me how to determine if the emulator has also connected on this port, or how to trigger this connection manually? The instructions indicate that it seems to make the connection at boot (being that the set up is done before starting the emulator) but this seems counter intuitive to me for the emulator to automatically search for such a listening service only on boot.

[android-developers] Re: Android 4.0 sensor emulation setup questions
I answered my own question a bit. It does appear that the emulator only connects on startup at present, not sure why it didn't work the first time I booted the ics AVD instance. Still, it would be nice to see a controlling application in the emulator that would allow us to view the status (successful connection or not) and control it in some way. Regardless of the rough edges, this is a huge blessing for developers working with advanced sensor applications. I'm mostly interested in the SdkControllerLib to create custom sensor playback and recording tools that will help me refine my application logic.

[android-developers] Side-effects related to RawContacts.ACCOUNT_TYPE
I am attempting to attach a small amount of meta data to existing contacts and have chosen to do this by implementing my won raw contact account type and custom data row mime type. I do not need to have any special sync backend so the account manager system does not seem relevant however this has me wondering if there is anything special that must be done to declare the mime types I am using. For example, if I want to insert new raw contacts of type org.devtcg.foo, is there any registry I must participate in to ensure these records are stable on the device? In testing and looking at the ContactsProvider2 source it seems like nothing special is required but it is difficult to prove for sure. Any help from someone in the know on the account and contacts system would be greatly appreciated. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: ViewGroup parent for merge
You definitely don't want to access the list directly from the
adapter. Instead for your design what you'd want to do is remove the
outer linear layout if you can and just have two separate XML files
with only 1 view each (text_row or icon_row). Then in your adapter
override the methods getItemViewType and getViewTypeCount. These
methods are provided for you to have two or more different types of
layouts for certain rows based.

[android-developers] Re: Push Notification Techniques: Discuss
I thought I'd chime in with some recent work I have done on this topic. The Google services on Android use Gtalk to implement push notifications and they do so using a persistent TCP connection as is the case with most other data-based push systems (like Microsoft's Exchange ActiveSync, for instance). While there is additional overhead, there are many ways to mitigate the burden on the CPU and the radio. I have constructed a simple demonstration of some of the techniques I have learned from studying Gtalk's connection which can be found here: http://devtcg.blogspot.com/2009/01/push-services-implementing-persistent.html. The important thing to note is that using an AlarmManager allows the CPU to sleep at relatively long intervals (it depends on your server implementation, but with IMAP you can get away with almost 30 minute intervals) while the radio remains awake but idle. I have been running my demonstration on my G1 handset for several weeks now and have been unable to detect any significant change in battery performance. One small point to make is that often push services drag on the battery for other less obvious reasons. For instance, if your e-mail arrives instantly, you are more often going to turn on the screen, then open the e-mail app and spend time reading your new messages. While I have no concrete estimation of battery drain, I think it can be reasoned that 30-60 seconds of screen activity uses more battery than a small keep alive TCP packet.

This seems entirely plausible given the packet based nature of the network. Tom. 2008/11/26 Mark Murphy mmur...@commonsware.com And the radio is necessarily always on. Yeah, but... I was under the impression that, in normal operating mode, the GSM radio is in a low-power state.

So, the question is: with an open-but-quiet Internet connection on a carrier data network, how much power draw is there from the GSM radio?

[android-developers] Service binding pattern and the out-of-memory killer
I have noticed most apps follow the pattern of starting and binding to their services during an activity's onCreate, and similarly unbinding during onDestroy. From my understanding, this means that if the user enters an activity with a transient service, but then leaves the activity using the Home key (and not Back), the service will remain connected even after stopSelf is called to indicate that the service is no longer busy. The implication of this is that the process hosting the service will have an oom_adj of 2, leaving it much less likely to be reaped by the out-of-memory killer even in the event that the service isn't busy doing anything. I tested this against the Music app in particular, and it is subject to this problem. Leaving the app with the home key will leave the process active with oom_adj=2, even without music playing. I have adjusted my application to bind/unbind during onStart/onStop which is the only work-around to this that I know of. In practice, the performance does not seem to be much different. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Is it possible delete rows from the top of a ListView (without recreating it)?
You would update your adapter and call notifyDataSetChanged (from the adapter). The ListView would perform a full layout and draw, which does not have as much overhead as you might think. For instance, it will only concern itself with the list items currently on screen. You cannot manipulate the innards of a ListView as directly as you want, and trust me: you don't want to. ListView is exceptionally complex and extremely well optimized.

[android-developers] Re: Network downloads in realworld uses
I suggest that you examine the code for DownloadProvider from the Android source tree. It properly handles just about every type of possible event the phone could encounter. That said, in my experience EDGE and 3G can switch transparent to the application, however you will see a somewhat significant throughput delay during this transition. Switching to Wi-Fi will always shut down mobile data connections (EDGE/3G) and so you will see your connections disrupted immediately and are expected to now retry on the new network. Wi-Fi will shut off after so many minutes of the screen being off, which will then re-enable the mobile data connections and again your program should reconnect. One pitfall to watch out for is that the CPU may have fallen asleep on you in which case only data transmission from the peer you are connected to will wake it up. So if your connection fails and you schedule a timer to retry, you may find that the timer never triggers until after the user has turned the screen back on. To avoid this behaviour, you would either hold a WakeLock (think carefully about whether you need this, it is very expensive), or use an AlarmManager which is capable of waking the CPU. To answer your questions more directly: 1. No, you must handle network failure as if it were a common and likely occurrence. Mobile data connections are inherently very unreliable. 2. Yes, but you should hold a WifiLock for this purpose. Also, you would use the ConnectivityManager to determine whether the phone was on a Wi-Fi network or not.

[android-developers] Re: JNI support in 1.0
I haven't specifically tested with 1.0, but with 0.9r1 it was certainly possible. The issue of it being supported, however, is more difficult. There is no distribution mechanism for native code, furthermore the /system image is not writable on normal phones. So unless there is a way to load native code from /data (I can't say one way or another; haven't tried), it's certainly going to be out of reach for any typical user to install.

[android-developers] Re: Audio cache strategies
This is exactly the sort of problems my application (http:// five.googlecode.com) must contend with, and unfortunately I have came to the conclusion that for 1.0, Android will simply not be able to support our type of application. Their current official recommendation is to work around this by constructing your own local HTTP server to both stream and cache (tee) the proxied content. Even ignoring the enormous overhead this introduces it still won't work. There are yet more problems lurking in the MediaPlayer which prevent applications which need information about the buffering heuristics built into the system. For instance, the MediaPlayer.OnBufferingUpdateListener class can supposedly be used to detect when the buffer is full (playback has begun), when it becomes empty again (playback chokes), and everywhere in between so the application using it can provide essential feedback to the user. I constructed simple tests which clearly demonstrate that onBufferUpdate is fired with entirely different metrics that I cannot understand, but clearly do not represent buffer fill percentage. In my tests, playback started anywhere from 5% to 25% buffer fill percentage, though it seemed more like the buffer fill percentage was total file progress (but not quite). Likewise, the buffer fill percentage never declines, so it isn't possible to detect when a song chokes. Once open sourced, I will be working to fix the broken MediaPlayer so hopefully I can target a 1.1 release without waiting on Google to fix this set of classes. Would've been really nice to have a heads up that maybe the MediaPlayer brokenness from back in M5 was not a top priority and was unlikely to make it into 1.0.

It has the following main requirements: a) I need to be able to play music without waiting for it to download. b) I wish to cache the music locally so that the user's favourite tracks don't need to be downloaded again. Currently my strategy is to download the files locally and discard the oldest ones when I need more space, keeping all the metadata in an associated SQLite database; but this approach is rather problematic and very brittle due to having to keep the database and the files in sync, issues with ensuring that a file isn't removed when something else is wanting to use it, etc. Not the least of which is that caching entire files means using up rather a lot of disk space --- some of my music files can be 15MB+. Also, MediaPlayer appears to be very picky as to what it plays from: it insists on playing from a file, or at least a file descriptor, and when you start playing it measures the length of the file and won't play past the end point, which is a bit of a problem if you haven't finished writing it yet. At least 0.9 has fixed the issue where getDuration() used to calculate the duration of the media based on the physical file length. Can anyone suggest any alternative approaches to doing this? What I'd *really* like to do is to be able to store my entire cache in a single huge fixed-size file, optionally on the SD card, and stream fragments directly to MediaPlayer; but I don't think that's possible and Java would probably be too slow anyway. Alternatively, a block-level cacheing HTTP proxy would do almost as well.

[android-developers] Re: Audio cache strategies
These tests were against 0.9, and I have complained loudly about it with any Google engineer that would listen. The outlook looks bleak to get these fixes in for 1.0. Also, in my tests, the MediaPlayer buffers poorly. It seems to take 2 - 5 seconds to even gear up and make a connection for some reason, and then it seems to buffer more than is necessary in certain circumstances. I'd like to load a simple test up on the HTC Vogue and see what more I can learn about how 0.9 behaves on real hardware.

In my tests, playback started anywhere from 5% to 25% buffer fill percentage, though it seemed more like the buffer fill percentage was total file progress (but not quite). Likewise, the buffer fill percentage never declines, so it isn't possible to detect when a song chokes. Is that on m5 or 0.9?

[android-developers] Re: ServiceTestCase instrumentation and remote callbacks
I have discovered more information about this issue which seems far
more troubling. I created a simple test which I thought would
demonstrate this bug but instead the test worked. So I returned to my
functional code and analyzed the logcat differences only to find the
following after I launch the instrumented tests:
D/AndroidRuntime( 764):
D/AndroidRuntime( 764): AndroidRuntime START
D/AndroidRuntime( 764): CheckJNI is ON
D/AndroidRuntime( 764): --- registering native functions ---

D/ActivityManager( 49): Received spurious death notification for

This is then followed by the tests seemingly running as expected but
without recursive binder transactions (callbacks don't fire). The
lines about the forced removal and crashed app are not present when
running my simple demonstration code which works otherwise as
expected.

[android-developers] Re: Adding content to a tab view dynamically
This seems a bit goofed up to me. First off, the FrameLayout holding
your tabs should initially be empty. the TabHost will manage filling
it in with the contents of the tab you've selected.
addTouchables is very certainly not what you want. You want to use
addView() but make sure that the view you get with getCurrentView is
what you expect. Make one tab have a LinearLayout with android:id=@
+id/foobarbaz, then check that getCurrentView hands you a view for
which findViewById(R.id.foobarbaz) succeeds to find your
LinearLayout. If not, try getCurrentTabView (there is nod
ocumentation, so we're just stabbing in the dark here). The other
solution is to better abstract the tab content in question and let the
abstractions manage themselves. You can do this by separating the
content of each tab into its own Activity and properly isolate them
that way. When you click some button in Activity A, A can manage
adding views to its layout entirely on its own.

The problem you are likely experiencing is that the Eclipse plugin only attaches by default to the process that hosts the activity configured in the Run dialog.

There are two ways around this: (1) make sure that your manifest file doesn't declare the service process as remote, or (2) switch to the DDMS perspective in Eclipse and manually attach to the correct service process.

[android-developers] Re: how to run an application compiled with gcc
This isn't entirely true. While Java is the only officially supported language, a quick Google search has revealed that folks have figured out how to use the ARM toolchain to build native C applications and even JNI libraries for use in Java. Similarly, projects like Jython demonstrate that it is possible to compile other langauges to the Java bytecode, or even directly to the Dalvik bytecode, and then in turn use those languages to develop on Android with the full Android platform API available. I fully expect that once source is released, developers will start pursuing ways to gracefully integrate other languages with the Android platform.

[android-developers] Re: Why do I get this SQLiteCursor exception ?
While that may be true, this still represents a critical bug in Android itself, specifically it looks like libsgl is the problem. You should submit this bug by using adb bugreport if you still have the running emulator up, otherwise just paste that log you have in the bug report and hopefully someone will be able to investigate. To clarify, there is no condition in which your code can be at fault for triggering SIGSEGV in the hosting dalvik process. Generally only bugs in Dalvik, the supporting JNI libraries, and/or the kernel can cause this behaviour.

You can't currently. I don't believe this is an inherent deficiency in the design of TabHost, but rather that you ought not construct a UI that behaves this way.

[android-developers] Re: Does KXML2 api be usable in andorid
I tried this, and it doesn't seem to be working. I added kxml2-2.2.2.jar to my build path in my Eclipse project and deployed my application. It is still using the kxml2 packages provided by Android, which throw an exception if I try to use WbxmlSerializer. What can I do?

[android-developers] Re: Changing the 9 patch when selected?
You're looking for a selector, I think.

[android-developers] Re: How to see android resources?
I had reverse engineered the binary format and have produced a much more thorough package than Mark's. I simply used my tool to replace every XML file found in all the system APKs on the emulator.

It was the answer I was looking for. May be you can help me with these resource files a little bit more. I do not recall reading about the attribute style in resource definitions. I checked the index of Android help and do not see an entry style.
