Re: [android-developers] FragmentStatePagerAdapter is not setting the UI elemtents when using Loader API
I don't think you have provided enough information to help. The argument
you supplied to instantiate() is just made available to the fragment
through Fragment.getArguments(). Presumably the problem is then somewhere
in your DetailFragment and how it is managing those arguments, but you
haven't provided any information about this.

Hello everybody, so I have run now with this problem when trying to use
FragmentStatePagerAdapter, I pick a specific element from a List and send
an array of ids with the position picked like this
intent.putExtra(ids, ids);
intent.putExtra(position, position);
Then the activity is called which load the fragment
@Override
public Fragment getItem(int i) {
fragments[i] = DetailFragment.newInstance(tradersId[i]);
return fragments[i];
}
The problem is that inside the DetailFragment the values are set with the
Loader API and even when they reach onLoadFinished and set the values it
never gets to be set.
Funny thing is that once I start switching views the values are set. Any
idea? Also the DetailFragment has a ListView inside which also loads with
the Loader API.
Sincerly yours,

Re: [android-developers] Using startActivity( intent ) multiple times, fails.
This is wrong in a number of ways: getLaunchIntentForPackage( com.android.email ); First, com.android.email is not an API. That is the internal identifier for the current e-mail application that is part of AOSP; there is *no* guarantee that such a thing will ever exist on the device. Second, more specific to your issue here, getLaunchIntentForPackage() returns a *launch* intent, for use in semantics like an app launcher. What you are asking for is not an app launcher; you want to run flow as part of your own task, not launch something different. In particular, what this Intent will do is bring the current e-mail app to the foreground *in whatever state it was last in*. The user may have been in the middle of composing a message, viewing something, etc. It isn't saying to bring them to the list of e-mail messages for them to import something. One other thing, when you say startActivityForResult() is not working, this is not because of an explicit vs. implicit Intent; this is because part of what getLaunchIntentForPackage() does is set FLAG_ACTIVITY_NEW_TASK, which says to launch the Intent as a separate task from yours (bringing an existing task to the foreground etc), which is central to the semantics of this being for app launchers not in-task UI flow.

Re: [android-developers] Re: The effect of differnet vendor RIL implementations of URC's on Android
Are you holding a wake lock? If not, you have no guarantees about how much stuff will run to give you such reports. The difference between these two devices could simply be that one of the devices has more stuff running that is holding wake locks to let you run more as a side-effect. (That said, this only applies if the device is running on battery. While plugged in Android holds a wake lock to keep the CPU from sleeping.)

The RIL will send up the update and Android has to wake up and handle it. Then from what I see in the TelephoneRegistry class, it has to check for registered records and call their callback function. If so, my question would be: wouldn't this be killing the battery if there are constant signal or cell updates, say if the device is moving fast from one cell to the other? The device would never have the chance to sleep. On Wednesday, August 22, 2012 11:33:40 PM UTC+3, sebouh00 wrote: Hi. I'm wondering if anyone can explain to me the following.

When the phones go to sleep, the nexus keeps updating the signal strength (and sometimes the cell location) but the Desire stops. This I reckon is due to how each RIL is handling the SCREEN_OFF intent. What I would like to understand is, what is the effect of the cell/signal updates on the nexus when the phone is sleep. I have a logger in the listener and I keep getting update logs during sleep. 1) Does this mean Android is waking up on each signal strength update? 2) If I deregister from this listener on screen off, will Android still wake up because of the way the RIL is implemented?

From the official Android Play store to the CNN App, this is probably the most common navigation we're seeing for dealing with menus on Android. It's beautiful, it's also a pain in ass to implement. After much searching I found an article on this on the official site http://android-developers.blogspot.com/2011/08/horizontal-view-swiping-with-viewpager.html I can open the source example and understand what's going on but my question is why does it take pages and pages of foundation code to implement something that should be core? There is literally 15 lines of code in that article, with another 3 lines of XML. Is that really pages and pages of foundation code? The code is implementing a FragmentPagerAdapter subclass with two methods, one to report how many pages there are, and the second to generate the pages. I'm not sure how this could be simpler...? It is true that for each page you do need to implement a Fragment subclass that contains your UI, so there is a little more code for that. But it's not huge. And if you really don't want to use fragments, that document also shows that you can actually pretty easily implement a custom PagerAdapter that generates raw views for the pages. There must be something I am missing here...? View transitions are another good example. Let's say I want my view to fade in or out or that I want it to rotate in 3D (just do a simple flip or slide in and out). I don't understand why the developer has to go so low level to accomplish these sort of task. I'm hoping perhaps I missed something and that there are wrappers for common transforms, etc...

I assume you mean the part of your window that is normally behind the status bar? If so, there is no simple way to do this. Aside from just making your app fullscreen so there is no status bar (and thus your content draws all the way to the top), you'd need to do an approach like playing games where you make your window translucent, set it to not have a background, and make sure that tap part of your window is transparent when it is drawn. Note that in 3.1 the platform know does some tricks to prevent that top part of the window from being drawn when it determines it is obscured by the status bar prior to any transformation applied by an animation etc. On Sat, Aug 11, 2012 at 2:20 PM, user123 ivanschu...@gmail.com wrote: I defined a scale animation from 0 to 1 for entering activity: overridePendingTransition(R.anim.scale, 0); In application tag in Manifest: android:theme=@android:style/Theme.NoTitleBar But I get a black topbar on the entering activity, while it scales... looks very ugly since the activity doesn't have this topbar.

Re: [android-developers] How to allow Landscape mode on Transparent / Translucent Activities?
Why are you making your activity translucent? If this is to allow the launcher to be seen through behind it, you shouldn't let the screen rotate if the launcher doesn't want it to -- the launcher has locked the rotation because it doesn't want to be rotated. If you actually are drawing everything in your activity so the launcher can't be seen, then why are you using the translucent theme?

When my Activity is launched from the Home Screen, most commercial phones will lock it to Portrait mode only. This is probably because the Home Screen only runs in Portrait mode, and applying the Translucent theme to my Activity makes it also lock to Portrait mode. But I would like to run my Activity in Landscape mode as well. Is this possible? For example, is there a way to dynamically remove the Translucent flag when a landscape orientation change is detected? -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Non sticky service gets recreated (indefinetly?)
Unless the service has something bound to it or it is started, it will not
be re-created.
You can look at the service state with adb shell dumpsys activity
services or adb shell dumpsys activity service package_name or
service_name. If your service is listed there, it will show you what its
current state is -- what is bound to it, whether it is started, etc.

I'm not sure what this means...? If you are concerned about the service
having too much overhead because you have bound to it and it doesn't need
to run just while bound, don't use BIND_AUTO_CREATE.

bind to a service if you don't want the service to stay around forever as a
cached process after you've unbound it.
Honestly I think it is pretty fully documented. But maybe we have a
misunderstanding -- once you unbind from the service, the fact that you had
previously bound to it has no further impact on how it is handled, and if
its process is killed after that it will not be restarted.
As long as you are bound to it with BIND_AUTO_CREATE, the system will try

Re: [android-developers] Non sticky service gets recreated (indefinetly?)
Also, if the service is not showing up as a running service in manage apps,
then that should mean that it is not started, so it it is created that is
because something has bound to it. You can see what is bound to it with
those shell commands. If it is not started, the only reason it would be
recreated is because another process continue to be bound to it after its
process is killed.

Re: [android-developers] How can I check the value of wtf_is_fatal?
Why do you want to do this? If you want to log an error that doesn't cause
your app to crash, use Log.w(). I generally recommend if you have a fatal
error, using Log.e() (though it is your responsibility to crash or whatever
the fatal error behavior is after that).
If you don't want the behavior of Log.wtf() (which is partly that it can
optional crash your app based on the setting), then don't use it. The only
reason to use it that I can think of is because you want the behavior it
provides. Is there some other reason you want to call that specific method?

Re: [android-developers] Non sticky service gets recreated (indefinetly?)
On Fri, Aug 10, 2012 at 12:17 AM, Johan Appelgren johan.appelg...@gmail.com wrote: Still occupies some amount of memory though, and the service's onCreate might not be cheap. I'm not sure what this means...? If you are concerned about the service having too much overhead because you have bound to it and it doesn't need to run just while bound, don't use BIND_AUTO_CREATE. Anyways, I guess this is one of those little undocumented things you just have to learn. Do not rely on START_NOT_STICKY if you both start and bind to a service if you don't want the service to stay around forever as a cached process after you've unbound it. Honestly I think it is pretty fully documented. But maybe we have a misunderstanding -- once you unbind from the service, the fact that you had previously bound to it has no further impact on how it is handled, and if its process is killed after that it will not be restarted. As long as you are bound to it with BIND_AUTO_CREATE, the system will try to keep it created and if the process is killed while you remain bound to it then it will try to restart it. As long as the service is in the started state, the system will try to keep it created/started, and if the process is killed then it will be restarted if it is not sticky. The decision about whether to restart the service is if either of those conditions result in it wanting to restart it. Again starting and binding are orthogonal to each other. You just have to know how each works individually, and what happens in the service is based on whether either of them drive it to need to be created. As I think is covered pretty fully in the documentation. -- 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.

Re: [android-developers] Non sticky service gets recreated (indefinetly?)
Binding and starting are completely orthogonal things. You bind to a
service to establish a persistent connection to it. You start a service to
have it run for some undefined amount of time separately from the caller.
A service needs to remain created as long as it is being asked to do
either of these things.
If you don't want it to stay created, either don't bind to it when you
don't want it around, or don't use BIND_AUTO_CREATE so you aren't forcing
it to remain created while bound to it.

Re: [android-developers] Non sticky service gets recreated (indefinetly?)
Binding to a service can only make that service's process as important as
the process of the client binding to it. If the client process is in the
background, it can't bring the service up beyond the background, so it
doesn't count as a running process but a cached process.

Re: [android-developers] how can I design a floating keyboard?
In the current platform your IME UI can only push app content up from the bottom of the screen. If you design it to be floating so that it doesn't impact app content, you can easily put it anywhere (if nothing else make the window fill the entire screen and leave all the parts transparent except where you want to draw your UI), but if you want apps to adjust their UI to accommodate the only option is to have their content shift up from the bottom.

Re: [android-developers] Re: How to set theme using resources from another application?
You can't really do this by simply pointing to a theme. The resources object is used across the view hierarchy to load resources; to set the theme from another apk you will need to have the resources coming from there, but then you won't be able to access any of your own resources that you need (like strings etc).

Re: [android-developers] Re: How to set theme using resources from another application?
That doesn't solve the problem, which is that you are trying to create a mix of resources from two .apks and you can't currently do that.

So this actually requires that you do *more* work on memory management. Second, let's look at the documentation: http://developer.android.com/guide/topics/manifest/application-element.html#largeHeap In particular: Most apps should not need this and should instead focus on reducing their overall memory usage for improved performance. And if you follow the link to getLargeMemoryClass(): http://developer.android.com/reference/android/app/ActivityManager.html#getLargeMemoryClass() We'll further emphasize this: This is the space available for memory-intensive applications; most applications should not need this amount of memory, and should instead stay with the getMemoryClass() limit.

Re: [android-developers] Programatically changing the screen brightness
I can't follow your question, but the code your posted has problems.
First, please don't set Settings.System.SCREEN_BRIGHTNESS. This is the
global brightness set by the user. It should not be changed by the
application. It is not intended to be changed by the application;
generally there are other things you need to poke to have the system pick
up the new value, and this is all in the realm of implementation details
that you shouldn't rely on and almost certainly will not work consistently
across devices and platform versions.
Second, you also have some code that is setting
WindowManager.LayoutParams.screenBrightness.
If you set this on your full-screen window, then while it is displayed on
the user it will force the screen brightness to the value you set here.
You do need to make sure your activity is full-screen. If it is, and your
activity is in the foreground, it will cause the brightness to change. In
this case you are immediately starting another activity and finishing the
current one, so it will only very briefly impact the screen brightness (if
it all) for however long that activity remains visible to the user.

Here is the code I am using:

Since I know brightness settings can only be used after the screen has

So the question, how do I get this done?

Re: [android-developers] Set bounds for one layer of LayerDrawable?
No, the bounds are where the drawable will actually render itself. If you want two different bounds, that should technically be two different drawables. If you need to have this all in one drawable, the only option I can think of is to make your own subclass of Drawable that computes the different bounds as you want them.

My approach is to use a LayerDrawable in which one layer uses different bounds (computed at run time). The attachement shows expected (top) versus actual (bottom) results. From what I can tell, setting the bounds for one layer also sets the bounds for the entire LayerDrawable.

Much less downloads would be required to get as much revenue if the free versions has ads. Could really a business model of only purchases generate as much revenue as purchases+ads?

public void onStop() { Log.i(JIM,CALL ONSTOP); super.onStop(); }

Re: [android-developers] Fragments Bitmap Recycling + a bunch of bitmap oriented questions.
If you have a fragment that holds on to a lot of memory in its view hierarchy and are concerned about this, then use FragmentTransaction.remove() to make it no longer visible -- that will remove it from its parent view and destroy its view hierarchy, so it doesn't hold on to any references. (If you are manually loading bitmaps in the fragment, in onDestroyView() you can clear the references there.) Of course this means a bit more overhead when the user returns to the fragment, since its view hierarchy needs to be re-inflated and initialized again. But it won't be any worse than the first time the user visited it, and you need that to be fast as well. It is true that FragmentTransaction.hide() does not remove and the destroy the fragment's view hierarchy, just doing View.setVisibility(). But that is not all -- it takes care of managing the fragment lifecycle so that fragment will be paused and stopped (since it is no longer visible). You can implement the lifecycle to free up resources if you need to. This will also result in them being freed when the entire activity is stopped, which is probably what you want as well. You shouldn't be directly hiding the view associated with a fragment. That is what FragmentTransaction.hide/show() is for. There is no need to directly hide the view owned by it, and doing so means that you are letting the correct fragment semantics execute. (And for what it's worth, if you have no reason to use fragments with ViewPager, there is nothing forcing you to -- you can write your own adapter that directly manages raw views and doesn't use fragments at all.)

Re: [android-developers] Regarding Application is not installed alert
It is fundamentally wrong to require a permission on your activity, and then publish intent filters for it that would allow other applications to try to launch it without explicitly expecting a permission (which means matching any standard filters such as MAIN for your main activities, VIEW, SEND, and on and on). These are two completely incompatible things. Publishing under one of these intent filters says hey anyone who wants this standard kind of activity, you can find me and run me and not know anything else about me! Requiring a permissions says hey you can only launch this activity if you explicitly know about this special behavior it has that requires you hold the appropriate permission to access.

Re: [android-developers] How to put ads in live wallpapers?
Let's assume that push advertising is a bad user experience. (It is.) Do you have a solution for presenting advertising to the user through a live wallpaper that doesn't suck? I can't think of one. If you can't either, maybe this is just not an appropriate thing to do. We created live wallpapers as a cool little thing to jazz up the UI, with an API that allows other people to make their own cool little things. That doesn't mean there are guarantees around monetizing these things through anything besides direct user payments... that wasn't really the goal of this feature, the goal was just to make it possible to have interesting things going on in the background of the home screen. Maybe there are ways to monetize these through other things besides in-app billing or some other such direct mechanism. If you think you want to try another way, you should at least have that as part of your plan from the start. Otherwise, you end up trying to shove some monetization on top of something that wasn't designed from the start to have monetization, which is probably going to be a bad result. And as I said, since monetization outside of direct charges isn't part of the core model around live wallpapers, there is even more of a burden on you to figure out how to do this nicely from the start.

Re: [android-developers] Re: Do we need images for all versions HDPI , MDPI , LDPI
Sure, if you are actually generating different bitmaps for different densities, then you must be doing this because you want/need to carefully control their graphics. However my original point stands: if what you are doing is drawing your icons at one high resolution and then scaling those down automatically to generate lower dpi versions, it is well worth considering just letting the platform do the scaling for you. Also keep in mind that for the new tvdpi density that is used on things like the Nexus 7, we *strongly* discourage developers generating their own bitmaps for it. Let the system take care of scaling those down (from the hdpi or higher density version you supply). This is what is happening for very nearly every single graphic you see on the stock software that comes with the Nexus 7. If it is good enough for what is shipping on the N7, it is probably good enough for you.

In these cases the unique approach is to export the image as a bitmap several times at different resolutions. Excellent point.

Re: [android-developers] Issue with device scaling on Nexus 7 Tablet?
Take care when creating a 9-patch that the marks you use around the edges are at least two pixels wide. If you don't, when it is scaled down they can disappear. Another thing to watch out for is that the graphics associated with your stretchable marks have one safe pixel before or after the marks, so that if the graphic is scaled you won't end up with a different color at the edge of the stretchable region (that color being a mix of the original color at the edge, and the color of the pixel next to it).

TransactionTooLarge means that the data being sent through the IPC call

I just checked my test case and verified that this doesn't kill the
service's process *if* it is in the foreground (with
Service.startForeground()). I'm not sure what may be different in your
situation... one thing to keep in mind is that when the user removes a
task, and it is not safe to kill a process associated with it, then that
process is marked as having a pending kill, and as soon as it becomes safe
it will be killed. So for example at whatever point after that you are no
longer foreground, your process will be killed.
There was a change in JB to make this interaction better about finding
processes associated with the app and killing them. If your service isn't
running in the main process of the app, its process should always be killed
now, where before it may not have been.
However in all cases it is only killed if it is safe to do so -- that is
if the process is at an oom_adj level that is safe to kill by the OOM
killer. Just running a background service means it is safe to kill; the
service itself will be restarted if you have indicated this is what you
want. This is not a new situation that your app needs to deal with -- its
process could always have been killed while in this state if memory was
needed elsewhere (for example if the user launches a game that uses a lot
of RAM).
Back to the exception you mention, I wouldn't like to see this in the
logs... if you can give me steps to reproduce it, it is something I would
like to investigate.
That said, your initial description is not actually a system problem as
you describe it -- yes your process gets killed, but this is a normal part
of operation you should be dealing with, and if you can't recover when it
is restarted then that is something that needs to be fixed in the app.

Re: [android-developers] Re: Do we need images for all versions HDPI , MDPI , LDPI
The platform can scale to whatever density it needs, there is nothing special about ldpi. If you are going to be providing the different densities simply by scaling the bitmap yourself, this is kind of pointless, because that is all the platform does when it needs to have the image in a different density that what you have supplied. In this case providing the different densities yourself is pretty much entirely a performance optimization -- the platform doesn't need to do the scaling at runtime when loading your resources.

either have a race condition (because this is being executed from multiple
threads), or something is clearing that flag. Either way, at this point it
looks like an issue in the app.

I end one with finish() and then call the next. If I exit out using the
back button, some time later one of the Activies pops up. Presumably
because the timed game round ends and the next activity is auto-started or
something.
Additionally, I have a timer loop using Runnable. Inside the loop I do
things like this:
if (game_time 0 game_time 5 flag)
{
flag = false;/// class variable
Log.i(WTF, Why do I see this message more than once?);

Well, this code gets run MULTIPLE times I can see the log messages.
If I upload the EXACT same APK to an ICS device, these behaviors do not
happen.
I also see this message in the log:

Re: [android-developers] New READ_EXTERNAL_STORAGE permission breaks file:// URIs
You can put your data in your own content provider. Actually, you should stop and think about doing this approach at all. You say this is for an app widget... why not provide the bitmaps as bitmaps instead of having it load the data elsewhere? Note that if you don't provide the bitmaps directly, anything you do means you are making this data globally readable by everyone (because you can't make any assumptions about the permissions available to whoever is hosting your app widget), which is generally a big no-no for security reasons. This isn't a launcher bug. Launcher is just one possible host of app widgets. You can't assume whoever is hosting your app widget will have any specific permissions. Also this is why the protection in JB is turned off by default. Right now app developers should be updating their apps to fix these issues, so when this protection is turned on for all users in a future release they will still work. Btw this change is described in the permissions section of the 4.1 API overview: http://developer.android.com/about/versions/android-4.1.html On Tue, Jul 17, 2012 at 9:21 AM, String sterling.ud...@googlemail.comwrote: Throwing this out for discussion here... Now that I have a JB device in-hand, I've found a sneaky little problem with the new READ_EXTERNAL_STORAGE permission. Specifically, if you pass another app a URI - say via a ContentProvider - that uses the file:// protocol, then the receiving app NEEDS the new permission in order to read from that URI. Thus, the new permission has the (presumably unintended) potential to break an unknown number of existing apps when it enters production: their ContentProviders will suddenly cease to work. I ran into this because I've re-implemented most of my AppWidgets to use file:// URIs for their imagery, rather than passing the bitmap directly through RemoteViews. [This was done as a workaround for http://code.google.com/p/android/issues/detail?id=17509.] And it works fine unless you enable the READ_EXTERNAL_STORAGE check on JB hardware, at which point the images fail to load due to a permission failure from Launcher. One solution would obviously be to report this as a bug in Launcher, and for the appropriate team at Google to add READ_EXTERNAL_STORAGE to its permissions. Not a great solution, though, because it only fixes this single case. All other homescreen-replacement apps, from everyone from OEMs to indie devs, would need to make the same change. And I can promise you some won't. Another possible solution would be for me to keep these images in internal storage, making them world-readable so the URI recipient can read them. I haven't tested this to see if it'll work, but even assuming it does, it's a change that anyone who generates a file:// URI would need to make. And probably, some of them are generating URIs to files that can't reasonably be moved to internal storage. So we're back in the business of breaking existing apps. I don't know the internals well enough, but is it possible that there's a solution that could be implemented at the platform level? That whatever platform mechanism fulfills file:// URIs would bypass the READ_EXTERNAL_STORAGE permission check? Or is this by design, platform team? If so, I think it really needs to be publicized.

The content provider was the recommended workaround, and it's done well until now. I would really suggest reducing the memory of your bitmaps then. This limit is actually important -- if you are pushing huge bitmaps into the launcher, you run the risk of the launcher failing when it exhausts its heap due to them. We have limits. Limits are important. Respect the limits. :) This isn't a launcher bug. Launcher is just one possible host of app widgets. That's what I said in my OP, yes. To fix this from the content-consumer side, every appwidget host out there would have to request the new permission. Which isn't likely. More than not likely, it's not going to happen. Which brings me back around to my main point: this is a permission change that needs to be made *in an app other than the one that's failing*. The file:// URI content provider can't make the change; it's the content-consuming app that needs to request the new permission. And that's not in the docs, nor is it something that's necessarily obvious to the content-consumer dev, especially if the testing they're doing is with non-file URIs. Not sure what you mean not in the docs -- it is described in the document I pointed to. I do agree that there should be more discussion of this, and I can assure you there will be -- that is why we are doing things this way, to have the facility in place for JB for developers to test against before a later change actually impacts apps. You say it's not a Launcher bug; I do see your point, but I've had differing opinions on that. If Launcher is happily accepting file:// URIs that point to external storage, shouldn't it be requesting the appropriate permission to resolve that URI? No. We are pushing to get away from the free-for-all of external storage; this is one of the steps in that.

(the process is after all in the process of being launched).

The Galaxy Nexus never installs things on external storage, because that

This is probably a bad interaction with the new app encryption at boot.

Re: [android-developers] How to stop terminate the Android application when using the native code
You just need to fix your native code so it doesn't do this.

Re: [android-developers] Handler.sendEmptyMessageDelayed() unreliable on some versions of OS?
Note that these times are *uptime*. If the screen is off, and nobody is holding a wakelock, then the CPU will go to sleep, and uptime will stop counting until it wakes up again. On Fri, Jul 13, 2012 at 9:24 AM, mapeters mapet...@ideasave.com wrote: I have a thread (guts implemented as a subclass of Runnable) whose job is to perform an operation on demand from other threads or automatically every two minutes if no other thread invokes the operation. The run() method of this Runnable calls Looper.prepare(), creates a Handler object in a member variable, uses that to call sendEmptyMessageDelayed(1, 3000), then calls Looper.loop(). Other threads use a method in this thread's public API to invoke its operation. That method just calls the handler's sendEmptyMessage(0) method to invoke it. When the handler's handleMessage(Message) method is called, it acquires a lock (ReentrantLock), calls the handler's removeCallbacksAndMessages(null) method and performs its operation (within a try/catch block). The finally section of that block calls the handler's sendEmptyMessageDelayed(1, 12) method then releases the lock. This works fine on every device I have tested it on, and by everything I know, it is a valid way to do this that ought to work on every version of Android OS. Recently, however, somebody claimed it wasn't running every two minutes as it should, and gave me the log file it produces to prove it (which it does). That log shows that sendEmptyMessageDelayed(1, 12) was called, and then 11 minutes later, the handleMessage(Message) method was called. I know this invocation of handleMessage() was in response to that sendEmptyMessageDelayed(1, 12) call because Message.what was 1 (a value used only by the sendEmptyMessageDelayed() call). How is this possible? I could understand the timing being off by a few seconds, but 11 minutes? In subsequent attempts to reproduce this, I have seen that timing being off by 45 minutes and more. This problem has been observed on an HTC One X running Android 4.0.3 and a Samsung Galaxy SII running OS 2.3.6. Has anybody else seen this issue? Does anybody have a suggestion for what might be causing this? My current position is that this is an OS bug, but I am loathe to just accept that and call it a day. BTW - just for kicks, I temporarily re-implemented this using a Timer object instead, and observed exactly the same problem (using Handler is a better solution anyway).

On Sat, Jul 14, 2012 at 1:30 PM, Latimerius l4t1m3r...@googlemail.comwrote: Giving the user a good feeling about using a device/app is a very tricky area. I worked for the official games industry for 7 years and I saw the attention these guys tend to give controls. While not every little Android app has to be as fine tuned as a twitch shooter, every app should feel good - something Apple is famous for understanding. You can't say that a painting app is good enough just because there are still a bunch of pixels left for the actual painting after we've rendered our UIs. Okay: Apple is famous for having great UIs. iOS does not have a hard menu button. I believe there is an implication that you can do a great UI here without relying on a hard menu button. You might well be right on this, however the decision to leave out the Menu button is of a much much broader consequence than just finger paint apps for children. There are apps for which an off-screen button is just *the* simple and natural solution, everything else is kludgy work-around. If there were no such apps at the moment, they would appear in the future. Except in the world on iOS where they manage to have great UIs, in-spite of the heavy burden of not having a menu button? Must be that Apple magic. Wish we had some of that. Saying no Menu button should be enough for everyone reminds a similar well-known statement that concerned 640kB of memory - supporting such claims you run an acute risk of getting on the wrong side of history. :-) But this is what I was really here to reply to. Seriously? You are comparing whether there is a physical button for invoking a menu vs. an affordance within the application to a statement that one will never need more than the *amount* of a certain resource? Well okay then. Oh btw, if you want to know whether the device has a physical menu button, you can use this: http://developer.android.com/reference/android/view/ViewConfiguration.html#hasPermanentMenuKey() So if it has a menu key, you can leave your old UI, and if it doesn't I guess you'll need to accept a UI this crappy like iOS. -- 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.

Re: [android-developers] READ_LOGS permission is not granted to 3rd party applications in Jelly Bean (api 16)
Hi, sorry this didn't get documented. The change is that third party applications can no longer get the read logs permission, however every app can read the logs containing only the lines *they* have written, without needing any permission. Keep in mind that access to the logs has never been part of the SDK, and is still not part of the SDK. If you are relying on it then, even after this change, you run the risk of breaking in the future. (And that is partly why this got lost for documentation, it is not part of the SDK, so there isn't really a place to document it, in fact documenting it would kind-of make it a part of the SDK which we don't want. :p) Also we really really hope that developers don't take this as license to further abuse the system logs and spew increasing amounts of stuff into it from their app. Log noise has been a continual problem on Android (not just for third party apps, we always struggle to ship the open source platform without a lot of noise), and if things continue to get worse we will probably make further changes to it to better control it.

It is not the kind of app functionality that 99% of users can even comprehend, let alone have a chance of deciding whether it is okay for the app they are installing. We have over the years gone through a number of different wordings of the permission, but at the end of the day it is just not something that can be sensible displayed to the user. So, it is now a development permission (a new concept introduced in JB), which will never be shown to users, but developers can enable through their development tools. -- 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.
