[android-developers] Position StaticLayout on Canvas
Hi I am trying to draw some text onto a canvas. I was using canvas.drawText() but i need the text to be wrapped so i am now using StaticLayout.draw(canvas) which works fine except i cannot position the text. I have read some posts that suggest using canvas.translate(x,y) but when i have to draw more than one text box i translate the canvas the first time and the text box is positioned but then when i translate the next text box the canvas just translates off the screen. Is there any way to position the text relatively to the screen. Any help would be great. Thanks -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Preventing Multiple AppWidget Instances
There's no way to prevent it, no. IMHO, your best bet is to handle it gracefully: if the user wants to add multiple copies of your widget, let them.

[android-developers] The best way to store data for animation
I'm making simple animation for my app, just series of many png files (about 700). At one moment there are only 20 bitmaps in memory. Now all .png files stored in assets. What is the best way to store such data? 1) load all files to byte[] arrays and them dynamically decode and recycle bitmaps. The fastest solution but it requires a lot of memory (about 2mb for 700 images) 2) load all files and save to internal storage. 3) load and decode all files and save them as bitmaps to internal storage 4) same as above but use external storage 5) ...other ways I need the fastest solution with low memory usage.

It does apply, because the Market team just does not reply with explanations. Plain and simple.

If they pull these apps then they also need to pull every other merchant offering credit card transactions. Only if those other merchants are not authorised by Google?

You could implement little stubs for onDismiss listener for the dialogs:

@Override

myActivity.myDialogDismissed(*DIALOG_1*);
}
});

The config activity can be made transparent and finish right away, so it's just there as a callback for your logic.

[android-developers] System signing a test suite
I'm writing a testing suite (for personal use only) for my other apps that triggers system intents. I know I need to add android:sharedUserId=android.uid.system to my android manifest in the manifest tag and I need to install my app in / system/app instead of the normal /data/data to have permission to send system broadcast intents. I have root access so that's not a problem. The problem I'm running into is, it appears I also need to sign my app with a system key. Where do I get a system key store, users names, and passwords? I assume I could build my own version of Android and sign it with my own keys, but since I have root access there should be an easier way right? I have a N1 with CM7 and the emulator I'd be fine with keys for either. Thanks. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: One User Has a Problem - How do I debug it?
Hello Jake In one of our apps, we've created a debug log table for these types of things. We send out a debug version of the app which writes all relevant messages to this table. Then we have a button in the app to allow the user to send us an email file containing the log information (or we have this done automatically in the case an exception surfaces out of our code).

[android-developers] Re: Cost of requestLocationUpdates
Hi Jake, This part of the code isn't well documented, but from my experience, here is how it works. minTime - notify me every X ms of an updated location. minDistance - notify me every X m of an updated location. So let's take an example. I request location updates every 1 hr and every 1km. So what happens? This means that the provider connection (gps radio or network) will be open until i get a reading that matches these criteria. So i'll at least get notified every hour (the timing isn't exact btw) or i'll get notified every 1km, whichever comes first. We see this happening when we're listening for GPS and the user is in their navigation app. So if the user is driving and receiving GPS as while we're registered, we'll get notified every 1KM since they are actively using the provider. If the provider is not actively in use, i think it'll initiate the check primarily using the minTime parameter. (This is just speculation on my part based upon what we've seen in our location-based apps, so take that with a grain of salt). This is definitely a great topic and requires a bit of experimentation to understand exactly how it works in theory and how it differs in practice on each of the device models.Hopefully someone from the Android team can shed some more light on this and to validate what i've said.

[android-developers] Re: how to show JSON data into list view
Can I suggest that you separate the JSON parsing and the List View display into separate components of your code? I'd recommend that you do a translation between JSON and your domain model (Java beans) and then use those objects to interact with your Array Adapter. That way you can separate the implementation details of data sourcing and display into separate concerns. This will also shield you from changes in the source JSON structure as well. If you go down this path, you can then write your own ArrayAdapter that works off your business objects. e.g. public class MyArrayAdapter extends ArrayAdapterMyBusinessObject In this object, you can store a private member points to the list of business objects. private ListMyBusinessObject list; Then its just a matter of pulling out the right object when the view is called and then mapping that to the fields that are in your list view.

I mean, look at what you, Romain, Xavier, and others do here: spending your own free time helping us out wherever you can with issues others can't. I presume you all do this because you care about the product and want us to have a good experience using it. That's why it truly boggles my mind that not a single individual on the Market Team gives enough of a damn about *their* product to respond to even a single post. So, unfortunately, the OP is absolutely correct. Support for the Android Market for both users and developers is essentially non-existent. And this lack of support (and for me personally the fact that no one on that team seems to give a damn) is the chief reason why so many developers have such a terrible perception of everything and anything that has to do with the Android Market. - TreKing http://sites.google.com/site/rezmobileapps/treking - Chicago transit tracking app for Android-powered devices -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Listening to call log changes when app is not running
Hi Rishi, Thanks for your suggestion. Unfortunately I can't do that because when the ACTION_PHONE_STATE_CHANGED is fired the call log still doesn't hold the most recent call(s). I resorted to register to ACTION_PHONE_STATE_CHANGED and when the state becomes CALL_STATE_IDLE I set up an alarm for now + 100ms and then when the alarm goes off I check the call log for changes... A bit crude, but that's the only way I could come up with that works regardless of the app running or not... If there's a better or a more Android-like method to do this I'd be happy to hear what you or the community thinks, but if not I hope this hack helps someone :) Thanks again!

Re: [android-developers] Re: Check permissions
There is *no* need to use a shared used ID. Signature-based permissions do this, in a much more clean way. Also as pointed out, you can't change your app to a shared used ID if it doesn't already use one. And I really discourage people from using shared user IDs; there are lots of subtle implications of doing that, which I would prefer just be avoided.

Just be sure that if you do such a thing it is in a secure way -- for example if this is structured as a Service that your main application binds to in order to have it do stuff with SMS messages, declare a signature permission in the help that restricts access to it, and use it in your main app. This way other applications can't get the permission and can't find to your service and abuse you as a security hole (in which case your helper app will get the blame, since it is the one accessing the SMS data).

[android-developers] Re: Listening to call log changes when app is not running
Interesting idea... So if I understand correctly, you suggest: 1. From the phone state receiver I'll start a service 2. The service will register a content observer 3. When the content observer calls back I'll stop the service Couple of questions re this idea: - I'll have to check in (1) and in (2) if the new calls are already in the call log to avoid a race condition, right? - Is there a difference if I register a content observer from the service or from the code that starts the service? If I understand correctly the only purpose of the service is to reduce the chance of Android killing the app, so where I register the content observer makes no difference. - Do you think I should still implement a timer and stop the service after the timer expires? The way I see it there's no guarantee that the content observer will hold all the calls on the first call back, so my only choice is to give it some time and see that there's no more callbacks... I appreciate your help - from my experience, these delicate matters make the difference between a piece of software that works 80% of the time than a piece of software that works 99% of the time (and that 1% is really out of our hands - someone should name it like any other physical constant :) Tal -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Strange nullpointer on setMessage() of a ProgressDialog
Basically what I do:
I invoke the method showDialog(PROGRESS_DIALOG_ID);
which looks like (copy paste from the tutorial:
protected Dialog onCreateDialog(int id) {
switch(id) {
case PROGRESS_DIALOG_ID:
progressDialog = new ProgressDialog(this);
progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
progressDialog.setProgress(0);
progressDialog.setMessage(Loading...);
return progressDialog;
default:
return null;
}
}
In a Handler I do a progressDialog.setMessage(Uploading...);, which
works finde.
Later on the handler calls a
activity.dismissDialog(PROGRESS_DIALOG_ID).
Now a second time I do the same as aboth.
I do showDialog(PROGRESS_DIALOG_ID);
But when the handler does the
progressDialog.setMessage(Uploading...); I get the following strange
Nullpointer inside the ProgressDialog
E/AndroidRuntime( 496): java.lang.NullPointerException
E/AndroidRuntime( 496):at
android.app.ProgressDialog.setMessage(ProgressDialog.java:294)
I'm on android 2.1
Any ideas what could be the problem?

Re: [android-developers] Content Provider for Private Database?
Jake, ContentProvider isn't just for exporting data. One useful thing it provides is data change notifications (based on data URIs). In practice, it means that ListViews with content provider-supplied data refresh automatically, and it's really easy to make other UI elements also update automatically by registering data change observers. Another useful thing is that it forces you to map your data into a hierarchical URI-based scheme. This, IMO, results in a cleaner conceptual model for your data. Yet another is that you can easily pass data references between activities by using a data URI. On the other hand, with content providers you can't just run a raw sql statement whenever you feel like it - all data access is structured, so you've got to do some planning first. Howerver, for debug info, I probably wouldn't bother with a content provider or a database at all. Just a text log file, with timestamps, so it can be cross-referenced with the logcat (if you can collect that too). And speaking of debug reports - have you looked at ready-made solutions for this?

Can you suggest some other alternative? Well, to share some experience - I use my own logger that can output to logcat or a text file, and has settings for individual facilities (i.e. output only network-related events, or worker-thread-related events, etc.), as well as crash logging. Writing it wasn't terribly difficult, and if I had to do it over again, I would. Perhaps this is another option for you to consider: log data to a text file on the memory card. Ask your user (since he's cooperating) to email it to you. Fix the bug - done - move on - probably in less time than it takes to understand a ready-made logging facility. Getting back to the original topic, so a Content Provider is a good paradigm to use across the board even if the database is only meant to be used internally?

Kostya is pro-ContentProvider. I'm far less of a fan. Notably: -- Data-change notification is helpful, and becomes increasingly helpful with more complex applications. Simple apps, though, can just requery their Cursors when they do a database change, and result is a savings in code complexity, since ContentProviders don't write themselves. -- Data URls are no more useful than other forms of primary key, except in relatively unusual circumstances (e.g., the recipient of the Uri really isn't using the Uri but is merely passing it along to activities that are keyed to the ContentProvider's MIME type). The costs of a ContentProvider are: -- You leak database connections (i.e., there is no place to close your SQLiteDatabase). -- The limited API that Kostya mentions, so much of makes a relational database worthwhile is tossed out. -- They are *world readable and writable by default*, so developers that fail to put android:exported=false on their provider elements in the manifest make their data available for all other apps on the device, purely by accident. If you like the benefits and don't mind the costs, feel free to use a ContentProvider. It's one of the more contentious architectural areas in Android, with its proponents and detractors, so on the whole I don't think there is a consensus right or wrong answer. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy Android 3.0 Programming Books: http://commonsware.com/books -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Looking for information on the Fragment dump() method (FragmentManager too)
Both of these classes have a dump() method which looks useful for
debugging. I tried to use them in a sample application, but I'm not
getting any output at all. My code looks like this from within my
activity:
public void dumpFragmentMgr() {
FragmentManager fm = getFragmentManager();
File dumpFile = new
File(Environment.getExternalStorageDirectory() +
/fmdump.txt);
if(dumpFile.exists()) {
dumpFile.delete();
}
try {
FileOutputStream fos = new FileOutputStream(dumpFile, true);
fm.dump(DIALOG, fos.getFD(), new PrintWriter(fos),
null);
fos.flush();
fos.close();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
I'm positive that I have fragments in my fragment manager. My output
file is always empty, although I can see the datetimestamp getting
updated. I'm always passing null for the 4th argument to dump() since
I have no idea what else to put there. I have enableDebugLogging set
to true. Any help please?

But I believe it's still true that both conditions must be met. I'm basing this on my own tests. I have a feature in my app that looks up nearby bus stops based on the user location. If the user moves far enough away, it updates to get the closest stops based on their new location. Originally, as I only cared about distance, I left min time as 0. The frequency of the update checks was fairly frequent (this was a while ago, so I don't remember how frequent, but enough to be noticeable). Since it was likely the user would not be moving much very much when using this feature, I didn't want the update check to happen that frequently, so I added a min time. In one experiment, I set this to 5 minutes. I used the feature, then hopped on a bus and got significantly further than the min distance in under 5 minutes. I did not get an update and my nearby stops list did not refresh until the 5 minutes were up, when the location check finally kicked in and I my listener was triggered because the distance was far enough. - TreKing http://sites.google.com/site/rezmobileapps/treking - Chicago transit tracking app for Android-powered devices -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Re: Content Provider for Private Database?
Fwiw, a database is way overkill for a debug log or other such thing. Databases aren't free -- all of their features come with significant costs. If you actually are using those features (queries etc) then they are useful. But for a debug log? You are bringing in a ton of overhead for no real gain. As far as databases vs. content providers, I definitely lean towards the camp of avoiding content provider if the data you are managing is never going to be made available to other apps. That said, content providers are such a common pattern in Android's standard apps (since they tend to publish their data to others) that most of the helpers for dealing with structured data are oriented around them. Also keep in mind that publish to others can actually be pretty broad -- for example if you are writing a messaging app, you probably have no reason to want to expose that data as a content provider to others. Except... well, if you are going to do a share option you will need to have a content provider for a URI to share with others. And in Android 3.0 the drag and drop and rich clipboard APIs are built around data stored in a content provider. Even there, though, there's no reason you couldn't take a hybrid approach -- have your application directly access the database, and put a content provider on top of the same database just for publishing specific URIs you want to make available to other apps.

RE: [android-developers] exception in getting data from cursor(database)
It could be a mess of different things. Could you post the error? How many
times does it loop before the exception? You might want to do
result.getCount() -1;i++ I haven't worked much with arrays and getting the
number of elements back but in VB if you have 10 items it returns 10, but
since arrays are 0 based when you use a counter to ref the position in the
array you would need to make sure you only go to 9. If you go to the full
count length (10) you get an index out of bounds exception.

[android-developers] Re: TableLayout issue
I agree that a TableLayout can always be replaced with Relative and/or Linear layouts, but I still find it a very convinient shorthand in a lot of cases. It's also a lot more readable than a RelativeLayout and it's also much easier to modify than the nightmare that a RelativeLayout is when are trying to move rows/columns around. I understand and appreciate that the RelativeLayout is usually the most efficient memory and computation-wise, but it sure is difficult to work with and buggy in some older versions of Android. Another reason I will be dropping 1.5 support soon. On Feb 28, 7:59 am, Jonathan Foley jonefo...@gmail.com wrote: I agree with TreKing.

This will give you proportional heights of the two rows and the ImageSwitchers will be laid out proportionally to take up half the width of each row. This is off the cuff so do check for sanity!

[android-developers] Re: Fragment question: inter-fragment communication?
Maybe this covered earlier in this thread and I'm still not understanding it. I like the idea of a each fragment communicating back to the activity rather than to other fragments. Then the activity can decide whether it needs to send information to other fragments. So is there an existing mechanism for a fragment to send a message to the activity? If not, I guess I could just create a handler in the activity and pass the handler pointer to the fragment so it can send a message to the activity. My use case is the activity is responsible for all changes to the action bar and to showing or hiding various fragments.

[android-developers] Re: Fragment question: inter-fragment communication?
A little more formally, have your activity implement an interface such as OnMyFragmentListener, so that the activity must implement a method like onFragmentDidSomething(). When your fragment wants to send something to the activity, it can do the following: ((OnMyFragmentListener)getActivity()).onFragmentDidSomething(...); You will get a ClassCastException in your fragment if the activity didn't implement the interface, but the really nice thing is that from your fragment's point of view, it doesn't have to care exactly which activity did the invoking. The cast is to the interface, not the activity. You could put the Listener interface definition inside your fragment class to keep things nice and clean. - dave On Feb 27, 9:58 pm, Gregg Reno gregg.r...@gmail.com wrote: OK, that makes sense.

Re: [android-developers] Launching an app from the quick search box creates a new instance of the app?
singleTask is for specific types of flow through activities; it is not a work-around for this kind of situation. As someone else said, your first step should be to actually *look* at the crash that is happening in your fourth scenario and fix it. You also haven't really given a clear idea of what you mean by it creating a new instance of your app. Does your app consist of only one activity? So you are actually creating a new instance of your activity? If so, then yes, this is expected, because the activity is being launched with different arguments (the ones from the search) so it needs to run to show that data. You do need to make sure you can handle this (fix your crash). To avoid the new instance being created, you can use the singleTop launch mode (please read the docs on it to understand it).
