[android-developers] Re: AudioTrack lag
Things like ring buffers are still the same idea, but I won't explain
how they're the same, because it would make the explanation more
confusing. Just hold onto the core idea -- the receiver and sender of
data each have their own buffers.
Heartfelt thanks for this great explanation.
I am a driver guy and i fully understand the concept of ring buffer
mechanism and how it used in ALSA.What i don't understand is that
sometimes write(){called by audioflinger} function call takes some
time to return(probably because of driver bug or latency) and
sometimes it doesn't return at all causing problem as shown below:
obtainBuffer timed out (is the CPU pegged?) in audiotrack.cpp
Is this buffer same as what is being allocated in the case of
streaming(sharebuffer = 0) in audioflinger.cpp file(constructor of
trackbase)
mCblkMemory = client-heap()-allocate(size);
If not then which buffer is this and where was it allocated.How can i
avoid getting this error other than solving it in driver?I don't mind
dropping some frames.
In the static case i guess when we call write() of audioflinger the
java pointer is directly passed to audiodriver by copying and we don't
maintain any buffers in this case?
And what is this track(audioflinger point of view)?How many tracks are
going to be created if i am playing music and what will be it's size??

Absolutely positively do not use the old raw screen size qualifiers; this simply do no work, and you can pretty much assume that you will not get what you want in some specific device configurations. Honestly, resource qualifiers are just not the level at which to work for oh there might be 50 more pixels available for me to put an extra row of buttons. I think you would be better of designing a single layout the gracefully adjusts when there is less space. You may want to write your own layout manager for doing that kind of logic (we don't really have a layout manager that can do include this view if there is space stuff), but that's not hard to do.

It is a presentation of a remote control[1] that simply would contain an additional row of buttons on FWGA (or let's say 1.78 vs 1.66 aspect ratio) resolutions. There is no keyboard whatsoever.

At that level, you really shouldn't be creating distinct layouts -- I'd strongly encourage you to design a layout that can resize appropriately to adjust for the screen. (long is to distinguish between HVGA and large screens like WVGA/FWVGA). Larger picture, you really should avoiding having layouts for different screen sizes as much as possible. You can already see with the number of sizes we have that this is just not scalable: QVGA, HVGA, WVGA (both med and high density), FWVGA (both med and high density), and of course both portrait and landscape versions of all of those. And in the future you should expect even more varieties (wider screens, larger screens, maybe even smaller screens). Also for a given size -- say FWVGA -- there is not a guarantee of exactly how much space you may have. For example a device may have a slightly smaller or larger status bar that impacts the space you have. And then if you are taking user input, there is the whole impact of the soft keyboard being displayed and thus reducing the space available for your UI during that time. So we strongly encourage that developers make use of the dynamic layout manager in the framework to design their UI to adjust for the exact space they have available.

[android-developers] Building a copy of a native Android system app
I need to create a slightly modified version of one of the native Android apps (to be precise: of packages/apps/Mms). For the sake of this discussion, please ignore the fact that this is a bad thing to do; that it will be version-dependent and fragile; etc. I'm aware of these issues and need to ignore them for the now. I simply want to build a copy of the app that I can install on a device. My first attempt was to copy the code into my standard Eclipse environment. This might work eventually, but I hit a huge spiral of dependencies... each time I copied code, it would bring in dependencies which forced me to copy more system code bringing in more dependencies. Second attempt was to build within the OS source framework (lunch, mmm, etc). I copied the Mms tree and made the obvious changes to package name, etc., to create a duplicate of the app. This installed and mostly runs! But, I am getting crashes in a couple of cases; looks like static lookup is failing on some system methods. The one I've seen so far is probably a red herring... for silly temporary reasons, I built from the 1.5 sources and tested on a 1.6 device. I'll be testing on the correct device in a day or two. But, before I dive too deeply down this rat-hole of ugly kludging 1) Will this really work? Or will I just hit another known trap soon? 2) Is this the best/only way to rebuild a system app?

[android-developers] Re: Non-parallel construction of DatePicker and TimePicker
Well there is no functionality missing in the way it was implemented but it IS ugly. And it cost me a couple hours of head scratching and digging to figure out how to set up a DatePicker after having successfully set up a TimePicker using setOnTimeChangedListener. As to making the change myself, I 't have no experience submitting patches and don't know what it means to star an issue. And since I have working code I will probably do what everyone else has done and forget about it. But maybe in the interest of design consistency and aesthetics, Google will dedicate the 15 minutes it would take to implement DatePicker.setOnDateChangedListener(...). They do have a well-tested model to work from, after all.

[android-developers] Sending email with attachment
Hi. I send an email from my app with this code:

emailIntent.setType(plain/text);

emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, Subject);
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, Body);
emailIntent.putExtra(android.content.Intent.EXTRA_STREAM, uri);
I'm trying to send an attachment (the 'uri' variable refers to a file
on the SDCard). When the email activity starts up, the attachment is
listed. But when I receive the email, it's not there.
I've tried various mime types, filenames, etc, but cannot solve
this... is there anything obvious I need to do?
Thanks.

This part works great when the context menu is created. I get the

However this:

only works when the item coming in is one of the main items in the context

[android-developers] Re: Help?
You might want to try calling System.gc() manually somewhere in there, like in onCreate. It has worked for me in the past to avoid that exception when recreating heavy weight activities. It's kind of an ugly hack, though. The call is documented as not even guaranteed to do anything. Also, you aren't supposed to be able to run out of memory if there is garbage to be collected that would prevent it. A wild off the wall guess as to why it works in some cases could be that the manual GC call triggers some finalizers which free up some memory not directly under the garbage collector's control, resulting in more free memory than the system thought it could get from garbage collecting. Or it could just be a bug, like you said. Last time I asked someone about the issue, they said to make sure I was calling recycle on all my Bitmap instances when I was done with them and things like that. I already was in my case, and it sounds like you've eliminated that in your test, but that's another thing to check in similar situations.

[android-developers] Re: AudioTrack lag
I haven't read the code (not even the Java side). I can only guess
that in streaming mode it allocates a buffer it manages as a ring
buffer, or something like that.
But I'd expect that to only happen at startup. Any delays in write()
calls I'd expect to be simply waiting for room to copy the data,
rather than driver issues. You should be able to save away the times
the write calls return in an array, and see if they're approximately
one buffer time apart. If you're seeing significant variance, then you
have reason to wonder why. GC would be one possibility. I don't know
the details of the dalvik GC, but it may need to do some operations in
a separate thread, or some operations of significant size (an an audio
time scale), which might be happening in other threads, making it
impossible to return to your thread in as timely a way as you'd like.
I can't think of why a driver, directly, would cause spurious delays,
but it might have to wait on a lock somewhere, for which there's
contention.
If you want to know, I'd start with collecting the timing data, and
seeing what you can correlate any anomalies with.
I'd take a look at the code, but I don't have my hands on it. My first
attempt ran afoul of it expecting to create symlinks, which weren't
supported on the filesystem I set up for the purpose, so I'll have to
come back to that when I clear higher-priority items from my queue.
Sometimes I google up this or that bit of system source code, but that
doesn't exactly make for good reading.
So you shouldn't take anything I say as being based on deep knowledge
of the system. I have deep historical knowledge of a wide array of
systems, which helps orient me, but that has its limits.
It's easy to seem smarter than you are on the Internet, by just
keeping your mouth shut when you don't know anything, and speaking up
when you do. I try to take a slightly riskier approach, and risk
overstepping my knowledge occasionally. You learn a lot more that way!

Things like ring buffers are still the same idea, but I won't explain

Heartfelt thanks for this great explanation.
I am a driver guy and i fully understand the concept of ring buffer
mechanism and how it used in ALSA.What i don't understand is that
sometimes write(){called by audioflinger} function call takes some
time to return(probably because of driver bug or latency) and
sometimes it doesn't return at all causing problem as shown below:
obtainBuffer timed out (is the CPU pegged?) in audiotrack.cpp
Is this buffer same as what is being allocated in the case of
streaming(sharebuffer = 0) in audioflinger.cpp file(constructor of
trackbase)
mCblkMemory = client-heap()-allocate(size);
If not then which buffer is this and where was it allocated.How can i
avoid getting this error other than solving it in driver?I don't mind
dropping some frames.
In the static case i guess when we call write() of audioflinger the
java pointer is directly passed to audiodriver by copying and we don't
maintain any buffers in this case?
And what is this track(audioflinger point of view)?How many tracks are
going to be created if i am playing music and what will be it's size??

[android-developers] Confused about activity lifecycle usage in the notepad example
Hi all,I am confused about activity lifecycle usage in the notepad example,notepad example use edit in place user model(NoteEditor.java),inserting new record in onCreate method, saving persistent state in onPause method,and save away the original text in onSaveInstanceState method. I am a J2EE programer,I can not understand the logic described above. why not make things simple as following: 1.Not inserting new record in onCreate method. 2.When user pressing BACK,it is equal as pressing save button in the editorform,so execute inserting or updating in onPause method if activity.isFinishing() is true. don't persiste use data if activity.isFinishing() is not true. 3.Not save the original text in onSaveInstanceState method,It is no necessary.If the activity is killed and back,restore user inputing data in the editorForm is adequately. I think this logic is more traditional and natural. Maybe I not understand the essence of the activity lifecycle.Please air your's opinion.

[android-developers] Talking to wpa_supplicant for TTLS / PEAP / TLS (Runtime+wpa_cli / JNI / LocalSocket(Unix domain socket) / wpa_supplicant.conf?)
Hi, (I'm new to posting questions on Google Groups. Suggestions on good posting behaviour are appreciated. :) ) This is what I'm trying to achieve: I would like to write an Android app that is capable of talking to wpa_supplicant. More specifically, I would like to connect to a WPA2-EAP secured network (with authentication methods TTLS / PEAP / TLS), but since the device will be used by several users, the user credentials will be supplied by the user in my app, instead of by wpa_suplicant.conf. I don't want to write my own supplicant software, I would like to be able to communicate with it. (I am able to connect to the network when I provide the user credentials as well in the /data/misc/wifi/ wpa_supplicant.conf file) I've looked at several solutions and their problems, and I would like some advice on them. Maybe I've overlooked something: - Solution 1: Using the Android Wifi API. Problem: The Android WiFi API doesn't seem to support TTLS / PEAP / TLS. Strange other thing is: It appears to support LEAP, but I can't find a way to supply the user credentials to the WifiConfiguration. - Solution 2: Letting the app write to /data/misc/wifi/ wpa_supplicant.conf and then reassociating. Problem: I understand from the API that apps can only write to their own private space or the external SD store. I've also tried writing to a file with the Terminal Emulator app. This doesn't work. I can only write wpa_supplicant.conf in the adb shell with root acces. - Solution 3: Talking directly to the control interface of wpa_suplicant using Unix domain sockets. I found that the Android API supplies us with the LocalSocket class for this. However, I have no idea how to cummunicate with the wpa_supplicant control interface domain socket. (I will also post this on a wpa_supplicant forum). - Solution 4: Using java.lang.Runtime and .Process for running wpa_cli and communicating with it. Problem: I expect there will be Manifest.permission conflicts. - Solution 5: Another option might be to use Android NDK / JNI to be able to use the helper functions in c that wpa_supplicant provides. Problem: This might be a solution, but it seems to me that it complicates matters a lot. And I also wonder if there might be some Manifest.permission conflicts. - Solution 6: Finding some open source Java supplicant code and adapting this. Problem: I haven't found it yet. (My C skills aren't so good). I really need some help on this. Is there somebody with some more experience on this topic? I hope somebody would be able to enlighten me by providing some answers or pointers on where to look. Any help would be greatly appreciated.

[android-developers] How to disable the Android device (android.permission.BRICK?)

Suggestions on good posting behaviour are appreciated. :) ) I would like to achieve the following: I would like to temporarily disable the Android device when the user performs 3 wrong logins in a row. The login is another issue I'm not interested in here. I'm interested in blocking the phone. I've been searching for some time now.

I'm interested in how to use this permission, and I'm also interested in what the consequences are. Does using some bricking method imply that the phone is permanently bricked, or is there still a way to restore the phone, so you don't have to throw it away?

[android-developers] Rebuilding just a single external project (wpa_supplicant) - toolchain problems
I'm wanting to rebuild wpa_supplicant from source (http:// hostap.epitest.fi/wpa_supplicant/) and I'm having problems getting the android toolchains set up so that I can properly cross-compile with the ARM compiler and link with the proper Bionic libraries. Ideally, I'd like to only have to build wpa_supplicant, without having to build the platform or any other part of the android system. I would then just push it onto the /system partition in place of the existing / system/bin/wpa_supplicant and be able to use a modified version of the supplicant. I've googled around quite a bit and am surprised that I haven't been able to find instructions on how to build only a specific external project. Therefore, I have a couple of questions: 1) Is there any reason to think that this isn't a fairly straightforward process? Should there be any reason that I couldn't just use the posted hostapd/wpa_supplicant source and have it fairly effortlessly link into android? 2) How do I set the build environment with the proper cross-compilers and include paths? I've looked at /build/envsetup.sh, but I don't know how to get this truly configured properly. I must be missing something. My dev machine is ubuntu 9.04, and I'm running a modified, rooted NexusOne with 2.6.32. Thanks for any help - hopefully this is a trivial task and there's documentation somewhere that I accidentally overlooked.

[android-developers] Re: Help?
Thanks Lance! Your tip about System.gc() doesn't seem to make a difference. :( Just so anyone that has this issue: I started with a stripped activity no allocations just loading my template seemed to resolve issues. From there I slowly started adding things and optimizing couple things that seem to leak. In any case using a G1 and opening and closing the keyboard fast does lead to the memory exception. So it seems that it does not clear memory fast enough. Now you might think who is going to open and close the keyboard that fast? Well it just helps put the phone in extremes situations where the CPU is slow and it can't free memory fast enough... It really sucks that this happens and I got many users complaining about this issue... :( Any other ideas tips, possibly catching this exception giving the CPU some time to clear memory and than start the activity? That would be perfect! Thanks, Moto! On Feb 21, 3:14 pm, Lance Nanek lna...@gmail.com wrote: You might want to try calling System.gc() manually somewhere in there, like in onCreate. It has worked for me in the past to avoid that exception when recreating heavy weight activities. It's kind of an ugly hack, though. The call is documented as not even guaranteed to do anything. Also, you aren't supposed to be able to run out of memory if there is garbage to be collected that would prevent it. A wild off the wall guess as to why it works in some cases could be that the manual GC call triggers some finalizers which free up some memory not directly under the garbage collector's control, resulting in more free memory than the system thought it could get from garbage collecting. Or it could just be a bug, like you said. Last time I asked someone about the issue, they said to make sure I was calling recycle on all my Bitmap instances when I was done with them and things like that. I already was in my case, and it sounds like you've eliminated that in your test, but that's another thing to check in similar situations.

Re: [android-developers] How to disable the Android device (android.permission.BRICK?)
I dont think I fully understand your question... Are you looking for something in the public API that will render a user's Android device useless for a period of time? Just how far do you expect this bricking to go? Will they still be able to use their phone for other purposes, e.g. making emergency calls? If you're looking for your app to be invasive to the user, you're unlikely to find it in the public API. Perhaps take a look at how the various lock screen apps work.

You could simply post (to a View or a Handler) a Runnable from onCreate() to do this. You can also try to do it from onStart(). Activity.onWindowFocusChanged() is definitely NOT the right place.

[android-developers] Chronometer with Android 2.1 issue
I have an app that plays Podcasts for AndroidGuys.com. I have released it to the public via Google Code (http://code.google.com/p/android- guys/) and I have received complaints from Nexus One owners and have even confirmed myself in the 2.1 emulator, that whenever I click Play Podcast I get a Force Close. Works perfectly fine on any other device. I have narrowed down the issue to these two lines of code involving the Chronometer. chrono_elapsed.setBase(SystemClock.elapsedRealtime()); chrono_elapsed.start(); The two other things that happen when you click Play Podcast is the creation of a notification in the notification slide window, and plays a streaming mp3 file. What could cause this to force close in specifically Android 2.1? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Help?
Was it actually your app that was getting the error? The Launcher suffered from this problem in 2.1 on a Nexus One if you had a lot of applications; it seems fixed in 2.1 Update 1. If it's your app, you can investigate this from the DDMS perspective. Select your app, hit the Update Heap button at the top, and then the Cause GC button, and you'll see usage by type of object on the right in the Heap window. Select a type, and you'll see a histogram of object sizes / counts. If you add the Memory Analyzer features (there are two, add them both; one provides the basics, and the other adds charts), to your Eclipse environment from the Ganymede update site, you can see a great deal more detail. Just click th Download HPROF File button. I won't even try to describe all the nice bits of analysis it can do. You may find you need to temporarily give your app WRITE_TO_EXTERNAL_STORAGE permission so that the .hprof file can be written to the sdcard. Once you've done this, you probably don't need it again, though I did have to re-add it for one session after I downloaded the Memory Analyzer.

It has worked for me in the past to avoid that exception when recreating heavy weight activities. It's kind of an ugly hack, though. The call is documented as not even guaranteed to do anything. Also, you aren't supposed to be able to run out of memory if there is garbage to be collected that would prevent it. A wild off the wall guess as to why it works in some cases could be that the manual GC call triggers some finalizers which free up some memory not directly under the garbage collector's control, resulting in more free memory than the system thought it could get from garbage collecting. Or it could just be a bug, like you said. Last time I asked someone about the issue, they said to make sure I was calling recycle on all my Bitmap instances when I was done with them and things like that. I already was in my case, and it sounds like you've eliminated that in your test, but that's another thing to check in similar situations.

I found a way that works perfectly! 1. Use a regular ToggleButton 2. Set your desired drawable on the toggle button using either drawable_top or drawable_bottom. Don't use left or right as the image won't be centered. 3. Now, you have both the text and an image. I just wanted the image so I needed a way to remove the text. I tried many different techniques like setting the font size to 0 or the text on and off to empty string, but there was always something wrong. The option that works is to set the lines=0 causing the text to take up 0 lines (making it disappear) leaving just the nicely centered image!

The fact that you had to explain it to a newbie makes me smile. Well you probably need to explain many other things to a newbie as well. Some prefix for member variables is very useful to avoid hiding them with locales and making it easier to read code to understand how it can impact state outside of its local scope. The trouble it adds is so small (just put an m before the member variable name) that I'd find it hard to consider it not worth it. :} -- Dianne Hackborn Android framework engineer hack...@android.com Note: please don't send private questions to me, as I don't have time to provide private support, and so won't reply to such e-mails.

I use m_ purely so I don't have to think up different names for my method parameters and to avoid things like this.foo = foo...it also avoids the accidental reference to a local variable when the member was intended (or vice versa). Is it awesome? No. But for me, it serves its purpose. The fact that it needs explaining is beside the point. In the end it is just a name and whether you understand the convention being used or not is irrelevant, it still just functions like a normal name. No different than someone naming methods or variables with _ to indicate something special. For the unaware, it's just a name. No understanding is necessary. - richard p.s.

[android-developers] Re: Zooming on android - google maps becomes slower
hi ,
thank you for the response, i tried the above mentioned method but it
dint find much changes in the drawing on the maps .
if u can fwd any worked example project , it would be more helpful ..
we are drawing the tracks/routes on the map after the completion of
the track . Problem exists when their is large amount of data
collected ( atleast after 10mi data drawn on map) and on every zoom
this is re-drawn and hence takes time to display .
thank u again ,

One easy thing you could do is early out on the shadow pass. Draw gets
called twice, one for the shadow layer and then again for the real
drawing. So unless you're doing something with the shadow pass you can exit
early:
draw(, boolean shadow)
{
super.draw(..., shadow);
if (shadow)
return;
}
mapView.postInvalidateDelayed(6000);
Also, why are you doing this? Invalidate is used to force a re-draw ... why
would you do this in the draw method?
