You are attempting to download news.txt. Given your code, when downloaded,
that file will appear in:
/data/data/your.package.here/files

No, but it might be in the wrong spot. If you could, post both your
AndroidManifest.xml that you are using with the above code and the actual
Java error you are receiving (via adb logcat, DDMS, the DDMS perspective
in Eclipse).

If it's the device, you probably cannot browse to the location using DDMS due to security restrictions. However, you should be able to use adb pull to pull the file given the full path, IIRC.

For example, if you were to use system icons plus some > additional ones in the same style that you made yourself, your > application's menus will look weird if the system icons are > redesigned. Android has been beaten up in the past for apps not having a consistent look and feel, particularly when compared with iPhone. It is likely to get beaten up for it in the future. While having apps with disparate UIs is part-and-parcel of having an open platform, it might be nice if there was at least some measure of guidance for how application developers *can* strive for a consistent look and feel if they so choose. In other words, let developers have the freedom to follow a lead as much as they have the freedom to chart their own course. Either a sporadically-consistent look and feel is a goal of the core Android team, or it isn't. Speaking as a developer, it would be nice to know which philosophy the core Android team is adopting. If the core Android team would like a consistent look and feel from apps (e.g., Ms. Hackborn's repeated insistence that "close" menu items are evil), then you're going to have to throw us a bone now and again with advice on how to maintain a consistent look and feel with the stock Android apps. I would think rules for how to have consistent menu icons might be part of that. If, on the other hand, the core Android team is not terribly interested in UI look fidelity, or feels it's not an issue because of re-branding that device manufacturers might do, that's perfectly fine. However, if the UI critics continue harping on the issue, please don't blame the developer community for not following non-existent style guidance. The worst answer is no answer at all, where we are left with conflicting guidance: the core Android team sometimes berating us for not slavishly following the stock apps design (e.g., not having "close" menu items) and sometimes saying that our efforts to follow the stock apps design may be fruitless (e.g., you might change the icon style out from under us). - Also, with specific respect to the icons, bear in mind that we're working under a 70MB hard cap, and so every KB we can slice off our apps makes it that much more likely somebody will keep our apps around, rather than discarding them to free up space. Hence, the interest in avoiding redundant icons. -- Mark Murphy (a Commons Guy) http://commonsware.com _The Busy Coder's Guide to Android Development_ Version 2.0 Available! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

I'm not sure when that all gets called, but there's a decent chance it is called when the screen changes content. That would probably trap both B->A and A->B; you'd need to figure out how to track which is which (e.g., also override onPreferenceTreeClick()). If that doesn't help, since PreferenceActivity extends ListActivity, you might try calling registerDataSetObserver() on the activity's ListAdapter and see if the DataObserver gets control when screens change. -- Mark Murphy (a Commons Guy) http://commonsware.com _The Busy Coder's Guide to Android Development_ Version 2.0 Available! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

The first one is easy: overriding onContentChanged() in your PreferenceActivity is no different than overriding onCreate() or onResume() or any of the other activity callbacks. Be sure to call super.onContentChanged(), and then log when onContentChanged() gets called (or set breakpoints, if you use a debugger). If it gets control when you need it, you should be in good shape. For the second one, see: http://developer.android.com/reference/android/widget/Adapter.html#registerDataSetObserver(android.database.DataSetObserver) (or http://tinyurl.com/dcrorv if that URL is too long for your mail client) Call getListAdapter() in your PreferenceActivity to get the adapter, then call registerDataSetObserver(), and see when the observer gets control (via logging statements or breakpoints). - Mark Murphy (a Commons Guy) http://commonsware.com Android App Developer Books: http://commonsware.com/books.html --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

The gist of it is that you create your adapter and set it up, in getView() or newView()/bindView() (depending on adapter choice), to see if the thumbnail has been downloaded. If so, use it for the list row being inflated/updated; if not, leave the ImageView in the row pointing to some placeholder Drawable resource. This means as the user scrolls, she will pick up the thumbnails. Also, at the end, you can quickly iterate over the rows (ListView is a ViewGroup, IIRC, so there are methods to iterate its children) and ensure each of those rows' ImageViews are using their associated thumbnails. -- Mark Murphy (a Commons Guy) http://commonsware.com Android App Developer Books: http://commonsware.com/books.html --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

HTC pulls source at whatever time schedule they deem appropriate. HTC engineers are working on the code constantly and can make their own decisions vis a vis their product lines. Neither you nor I, nor possibly Google, is in position to tell HTC what they can or cannot do. Now, if HTC is sensible, they will primarily stick to major releases plus milestone bug fix updates, but that's not something you should be relying upon. > You do realize that all > releases till today have come from a closed source project and not > AOSP? HTC may have access to a private *repository*, but AFAIK, the bits are still open source. Open source is a matter of licensing, not a statement of public collaborative development. > (Even if Google doesn't actually push the code/release to tmo, they > certainly do tell tmo (and other carriers) when the code in the repo > is "stable enough" so they can pull and release. I certainly would hope so. > What I'm asking for, > is that at this point in time (eg Google has designated the code as > "stable enough to release") we get an official SDK - is that too much > to ask?) Of course it is. A "point in time" is infinitesimally short. Assuming you were being loose with your terms, how long would you consider a "point in time" to be? A second? A minute? An hour? A day? A week? A month? A year? Let us suppose that they tag whatever repository HTC works from for each major release. Once they tag the firmware release -- in effect, designating the code as "stable enough to release" -- they still need to build, test, fix, package, and release the SDK. That will take some time, even if they have been doing some of that work along the way, because up until now, the firmware has been a moving target, and the apps that ship with the firmware are not built on the SDK. For example, they may not test on Windows routinely due to the hassles involved in building the Windows version of the SDK. Should that take months? No. Might it take weeks? Possibly, depending on what is all involved and how many people are doing the work. Now, the *right* answer is for this to be a true public collaborative development project, so nightly builds of emulator images and corresponding SDKs are available, so we can apply tinderbox and smoke testing sessions and the like. In time, we should be able to cut the time between tagging the final shipping firmware and releasing the corresponding SDK with emulator images to be hours, not weeks. And perhaps it's at that level already, and I just haven't seen it since we haven't had all that many releases yet. But this still does not prevent hardware manufacturers from doing what they want. As evidenced by "pre-N" wireless routers, hardware manufacturers are not necessarily constrained by what would seem to be common sense to us out here. They'll do what they do. So if a device (e.g., G2) contains bits of cupcake in advance of an official cupcake-based release shipping, that was the manufacturer's decision. -- Mark Murphy (a Commons Guy) http://commonsware.com _The Busy Coder's Guide to Android Development_ Version 2.0 Available! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

I don't have a direct answer, but JTwitter uses HttpUrlConnection, uses
the same general technique you're describing, and it works on Android.
Take a peek at their code and perhaps you'll see something that helps.

Yes. You're calling setContentView().
In most activities, setContentView() is called once, early in
onCreate(). It is infrequently called in an event handler (e.g., button
click callback).
More importantly, any widgets you got after the first setContentView()
and before the second setContentView() are unusable. Hence, your
findViewById() call immediately before the setContentView() will return
you a widget...but that widget is then taken off the screen by the
setContentView().

All I can tell you is that having setContentView() in a button's click handler is a "code smell". Having more than one setContentView() in an activity is possible but rather unusual and not recommended for newcomers to Android. Change your code to only call setContentView() once, early in onCreate(). If that does not clear up your problem, confirm your ImageView works with something other than the downloaded GIF, such as a Drawable resource (e.g., res/drawable/test_image.png). -- Mark Murphy (a Commons Guy) http://commonsware.com Android App Developer Training: http://commonsware.com/training.html --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

Is this possible? Not directly. And, when you "are hacking the framework", you might consider making a patch to allow one to define "extras" in the manifest to put in the Intent used to launch from the launcher. Or, perhaps you can use an alternative home screen (e.g., dxTop) and work with that developer on this project. However, it should be fairly trivial for you to create a shallow activity class hierarchy to handle this, at least as a workaround. For example, suppose the name of the activity you presently have is FooActivity. You're trying to launch FooActivity in one of two modes, and your attempts to do so via modifying the Intent used to launch the activity has been foiled. So, do the following: 1. Make FooActivity abstract, requiring a boolean useFullScreen() method 2. Create FullFooActivity and HalfFooActivity, each extending FooActivity, with FullFooActivity implementing useFullScreen() to return true and HalfFooActivity to implement useFullScreen() to return false 3. Create separate entries in the manifest for FullFooActivity and HalfFooActivity, each with the standard launcher intent-filter 4. Use useFullScreen() to do whatever it was you were looking to handle via the customized Intent Clunky, but it works, until you can amend a home application that is more amenable to your requirements. -- Mark Murphy (a Commons Guy) http://commonsware.com Android App Developer Books: http://commonsware.com/books.html --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

Here are three off the top of my head: 1. You want third-party programs to use the service (even if you are using it locally, it needs to support AIDL interfaces and such for use remotely) 2. You are reusing a service from a third-party program 3. You want part of your application to run with different permissions than another part of your application (e.g., firewalling off certain sections), and so you split part of it out into a remote service > -Is there any other resource apart from API reference, APIDemos and dev > guide for this topic that one would recommend?(Some of the blogs are > a bit outdated) You mean besides (*cough*) various Android books? ;-) In all seriousness, services have not received quite as much attention as activities.

Is that correct? Best, yes. Only, no. AFAIK, you can call startActivity() from a service, though your users may threaten you with bodily harm if you do so, since you might be interrupting them in the middle of something else they are doing. -- Mark Murphy (a Commons Guy) http://commonsware.com Warescription: Three Android Books, Plus Updates, $35/Year --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

You can try that. If the server in question offers any examples of
accessing its content programmatically (e.g., example curl or wget
commands), review those and see if there is anything obvious you are
missing. Of course, the best solution is if somebody offered a Java API
for accessing this Web service (e.g., JTwitter for Twitter).

You cannot use the ListActivity methods for managing the second
ListView. You will need to use findViewById() and handle that ListView
manually.

I seem to recall there are various local proxy servers you can use to intercept HTTP traffic, though getting a proxy server to work with the emulator is not terribly easy given the number of questions that seem to come up related to it. Instead, particularly if you are using OS X or Linux as your development environment, I would focus on trying to get curl working. Once you have curl properly downloading the content, converting that into Android code (whether URLConnection or HttpClient) should be relatively straightforward. You might also inquire with whoever is hosting the server if they have any recipes for Web service access. -- Mark Murphy (a Commons Guy) http://commonsware.com _The Busy Coder's Guide to Android Development_ Version 2.0 Available! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

Probably, that is because they cannot browse /data due to security
restrictions.

They are in the same spot on the device as they are in the emulator. You
just cannot browse to them. However, you can use adb pull to download them.

You have all of same folders on the device; you just cannot browse them.

Stoyan Damov wrote: > I can't provide a way to reproduce the problem. 1. Create a fresh project. 2. Copy your entire res/ tree out of your current project into the fresh project. 3. Try building. If the build crashes, then zip up the new project and attach it to the issue. Or, try winnowing out some resources (e.g., ones you might not want to upload) and see if the problem persists -- if the problem goes away, it may be tied to the resources you removed. If that doesn't crash, then the problem depends on other stuff (e.g., your original project's manifest, other build settings you may have enabled) and may truly be difficult to reproduce without uploading your original app, which I suspect you may be less than inclined to do. But if you really want this "TERRIBLE BUG" fixed, you really should consider at least trying to give the developers steps to reproduce the crash. - Providing steps to reproduce failures, whether in tools or class libraries or whatever, has been a standard of professional application development for a couple of decades now. I distinctly remember getting yelled at by engineers for failing to provide steps to reproduce bugs back as a summer intern in 1990, and I don't get the sense they were cutting-edge on that topic. It's also a quite common request in open source projects. For example, here is where Mozilla asks for steps to reproduce the problem: https://developer.mozilla.org/en/Bug_writing_guidelines And Ubuntu: https://wiki.ubuntu.com/Bugs/HowToTriage#Improving%20a%20bug%20report And OpenOffice.org: http://qa.openoffice.org/ooQAReloaded/Docs/QA-Reloaded-BasicRules.html And Moodle: http://docs.moodle.org/en/How_to_add_steps_to_reproduce_to_a_bug_report Heck, even not-really-open-source Microsoft is into the game: https://connect.microsoft.com/content/content.aspx?ContentID=3480&SiteID=168#BM8 As one person put it, "If your bug is not reproducible it will never get fixed."

I'm sure there are some folk who could eyeball some sample code and point out possible problems but may not have source they are in position to upload. That's one of the many advantages of having sample projects that reproduce possible bugs.

Mariano Kamp wrote: > I use a static member for that and it makes my eyes bleed. Umm...hmm...well...er... If you want your service to completely go away between alarms, you need your BroadcastReceiver to be registered via the manifest, rather than tied into the system via registerReceiver() in the service. The latter approach would likely keep the Service referenced and kept from being garbage collected. Given that, we now need to allocate a WakeLock in a BroadcastReceiver and get it over to a newly-minted Service. WakeLock is not Parcelable. Hence, I see no way to get the WakeLock to the Service except through some static data member, somewhere. Whether that is a member on the Service, on the BroadcastReceiver, or in some third class is an implementation detail. On the other hand, using registerReceiver() would allow you to keep the WakeLock in the Service object without the static data member. It's a trade-off -- if your alarm will fire frequently enough, it might be better to keep the Service around rather than reallocating it all the time. If your alarm is rather infrequent, though, I'd think it would be better to let the Service go away and get reallocated when the alarm fires. I'll be writing up the infrequent-alarm case (even though my sample code will probably have the alarm going off every 5 minutes or so, just to provide more rapid feedback to those playing with the code). The good news, though, is that Ms. Hackborn's technique works great -- haven't missed an alarm in 12 hours (every 5 minutes), and the device definitely has been asleep between alarms, given the battery level. > And > it makes it harder to handle cases where start is called more than once. That problem can be dealt with, despite the static data member. Though I'll need to beef up my sample some for this scenario -- I was thinking the service would be long since wrapped up before the next alarm fired. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy _The Busy Coder's Guide to Android Development_ Version 2.0 Available! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

If you are using RelativeLayout for the rest of the screen, just add the icon as another widget, anchored to the top and right. If you are using a series of nested LinearLayouts for your current widgets, either switch to a RelativeLayout.

Have you tried using setReferenceCounted(true) on the WakeLock? From a glance at the WakeLock code, you should not need to have two WakeLocks in your case -- one reference-counted WakeLock should suffice. In the scenario you described: -- The activity tells the service, "yo! sync me!" -- The service acquires the reference-counted WakeLock (count now = 1) -- The alarm goes off and starts the service -- The started service acquires the *same* reference-counted WakeLock (count now = 2) -- The work from the activity-initiated sync wraps up and releases the WakeLock (count now = 1 and we are still locked) -- The work from the alarm wraps up and releases the WakeLock (count now = 0 and the lock is truly released) Admittedly, this is all theoretical, as I haven't tried reference counted WakeLocks, though I think I'm going to give that a shot here. > The short story is, passing in a wake lock using a > naive approach of a static variable doesn't work when the service can be > started again during its runtime.

The BroadcastReceiver needs to have access to the WakeLock. If this is a registerReceiver() case, it can use the same object without resorting to a static data member; otherwise, it'll still need one. I'm working on this stuff right now.

[android-developers] Re: Observation and comments on Android and "regularly" scheduled events
Dianne Hackborn wrote: > Yes you need to use a global variable for the wake lock. Gross, but it > works. OK, here's a cut at a sample app: http://groups.google.com/group/cw-android/web/Alarm.zip [NOTE: If you found this message in the archives and are reading it after June 1, 2009, please visit http://commonsware.com/AdvAndroid/ and download the source code from the link provided there, as the code probably has changed] It needs more testing, particularly for Mr. Kamp's scenario, but I think it has a chance of holding up. Note that if you try building it, adjust default.properties to reflect your SDK location, and you'll need an SD card (or card image in the emulator). The goal behind this example is to demonstrate what a lot of people have been requesting: cron-style functionality. Meaning, a scheduler should trigger their code on a fixed interval, including from the point when the device boots, and should cause the code to run even if the device is otherwise asleep. It also attempts to handle Mr. Kamp's scenario where the same logic might also be invoked beyond just the scheduler, and where the logic might sometimes run longer than the alarm period. When installed, it will set up a RECEIVE_BOOT_COMPLETED BroadcastReceiver, which in turn will set up an AlarmManager ELAPSED_REALTIME_WAKEUP alarm set to recur at five minute intervals. The app's "purpose" is to add an entry to a running log file on the SD card (placed there for simplicity when testing on a device). The actual work to log the data to the file is done by a WakeWorkManager. This class manages a background thread for a service with automatic WakeLock management for background work. It wraps a LinkedBlockingQueue and, so long as there is work in the queue, keeps a partial WakeLock. This allows the service (and the BroadcastReceiver that starts the service upon an alarm) to "fire and forget" -- work will get done and the service will stop when everything is done, with a WakeLock ensuring the device will run only as long as is needed. The service/BroadcastReceiver pair needs a second WakeLock to ensure that everything stays awake long enough to pop the work into the work manager. However, this second WakeLock is then released (the "forget" part of "fire and forget"). This second WakeLock is a static data member on the service class, which, as Ms. Hackborn indicates, seems unavoidable in the current Android SDK. C'est la vie. Right now, the WakeWorkManager uses only a single background thread. If jobs will routinely take longer than the alarm period (e.g., slow data transfer), you'll probably want more than one thread. Implementation of this is left as an exercise for the reader. I am definitely up for comments, particularly if you see that I am screwing up WakeLocks or whatnot. Either reply on this thread or join the cw-android Google Group and chime in there. Thanks to all who contributed ideas and insights, on this thread (e.g., Ms. Hackborn, Mr. Kamp) and on past threads (e.g., Jon Culverson). -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy _The Busy Coder's Guide to Android Development_ Version 2.0 Available! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

Visit http://commonsware.com/AdvAndroid, download the source code, and look at WebView/GeoWeb1. I just put a Log.w() call in onCreate() and things behaved as expected: I got the onCreate() when I first fired up the app, but when I clicked on Home, then clicked on the app again in the launcher, my existing instance popped right back up and I did not get a second onCreate() call.

Try loadDataWithBaseUrl() instead of loadData(), supplying some bogus

If this is happening in an Activity, you can use View#postDelayed() to
schedule a Runnable to be executed after such-and-so delay.

You will have better luck asking those questions some place that is focused on server-side Java. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy _The Busy Coder's Guide to Android Development_ Version 2.0 Available! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Re: how to add "--core-library" to Eclipse ?
Dan Bornstein wrote: > Maybe it needs some further wordsmithing. As another "for instance" of this error, I am working on Android-ifying some existing Java code that relies on java.beans.PropertyChangeListener and java.beans.PropertyChangeEvent. I can pull those files out of Apache Harmony, and they are nicely self-contained -- PropertyChangeEvent references PropertyChangeListener, but everything else they use are supplied by Android. When I tried putting src/java/beans/PropertyChangeEvent.java and src/java/beans/PropertyChangeListener.java in my source tree, though, I triggered the --core-library error message from dx. > In particular, dx > rejects the definition of classes in namespaces which are already used > by classes in the standard boot classpath or are likely to be defined > in future incarnations of the platform. The problem is that you put us out here in a bind: we can't use your classes (because they are not in the SDK) and you won't let us use our edition of those classes. I would recommend the --core-library dx error message have a link to some documentation page where this gets spelled out, so we know what to expect. In particular, a list of the prohibited namespaces would be handy, so we don't have to just guess what we can and cannot use.

Android is Linux-based, so your path separator should be / instead of \ in the final parameter on your adb push command. 2. You may not be able to push files to /data/data on the emulator. You definitely cannot on a device. Your files do not belong there. Put them in /data/data/your.package.here/files, where your.package.here is the Java package associated with your Android application. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy _The Busy Coder's Guide to Android Development_ Version 2.0 Available! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

Per the documentation: "You can not receive this through components declared in manifests, only by exlicitly [sic] registering for it with Context.registerReceiver()." In your case, you are trying to receive this through a manifest-declared receiver, which will not work. Either switch to a registerReceiver() implementation, or use AlarmManager. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy Android App Developer Training: http://commonsware.com/training.html --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

You can store lists and > maps of Strings. They probably consume more CPU, though. If the service is in the same process as the activity, you can use the singleton pattern and have the activity call some method on the service object. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy Android App Developer Books: http://commonsware.com/books.html --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
