[android-developers] cookie management under webviews
Hi, when I´m set 180 Cookies in my WebView, these 180 cookies are saved and can be displayd again. When I´m create 181 Cookies, just 150 are stored (Number 32-181). Now when I set 181 Cookies, just 151 are stored and so on... Why is this so? Is it a bug or what are the maximum values for cookies respectively how many cookies can be stored? -- -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Updating APK that supports 3.0+ only
On Thu, Jun 20, 2013 at 11:35 AM, Darren McEntee darren.mcen...@gmail.comwrote: My question is, when i upload the new APK to my Google Play account, where the app is currently listed: (1) Will the current users of the app who are on Androd v2.1 - v2.3 just not get the updates from that point onwards until they update their Android OS version? To my understanding, correct. They see no updates. I've seen the behavior myself. I have a 2.3 phone and have many apps that show having been updated recently, but that device received no such update. (2) Will **NEW** users of the app running Android v2.1 to v2.3 not see the app listed on Play if they search for it? To my understanding, yes, they will see the last published version that supported their device. And (3) can i have an APK for user of 2.3.x and *below* ... and the *another *APK for users on v3.0+? Yes, see Multiple APK support. However, it's probably a better idea to try to support every version you want to target in one APK using reflection and other such strategies. - 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] Updating APK that supports 3.0+ only
Thanks for the update TreKing, So: (2) Will **NEW** users of the app running Android v2.1 to v2.3 not see the app listed on Play if they search for it? To my understanding, yes, they will see the last published version that supported their device. Ah ok, so this might work. If the older Android users get offered the latest version of my app *that their device supports*, and new android users get the newer version of the app, then this still accounts for all Android users. Can any confirm this? Or how can i get Google to confirm this? Thanks a lot! Darren. -- -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Handling process killed by system
Hi, I've been reading intensively the Android Application Framework FAQ (http://developer.android.com/guide/faq/framework.html) and it says that the system can kill process if needed to free memory. Well, fair enough, only it also destroys singletons and static instances. So when we launch the application back after that, it tries to restore itself, but fails miserably because all static singletons are no more available. What bugs me is that the same documentation (Framework FAQ) specifically says : You can take advantage of the fact that your application components run in the same process through the use of a singleton. This is a class that is designed to have only one instance. It has a static method with a name such as getInstance() that returns the instance; the first time this method is called, it creates the global instance. Because all callers get the same instance, they can use this as a point of interaction. For example activity A may retrieve the instance and call setValue(3); later activity B may retrieve the instance and call getValue() to retrieve the last set value. But it's not so true, as these singletons are not reliable at all. I mainly use singleton in my apps to store session variable. But some of this variables are quite complex (it can be information about the user, trees of object, etc). For exemple, I'm working on an ordering application that stores in a singleton a map of stuff the user wan't to buy. This maps is complex, it could also store information such as what kind of shipping option does the user want, etc... But let's say I start the app on a cheap device (with low memory), I start shopping, but I then receive a call from a friend, I hang up, then I forget what I was doing, and launch Angry Birds, and then hey, that's right, I was buying stuff, etc... I go back to the application, and the singletons don't exist anymore. Okay, looks like it's a bad idea to use static. But the FAQ is misleading, is it not ? The singletons are not really persistant : Once the order is finished, they are gonna be destroyed straight away. I guess that if running the app on api level 14 or more, I could use the onTrimMemory method from the Application class (http://developer.android.com/reference/android/app/Application.html#onTrimMemory(int)) to save/serialize my singleton there, and when the application is relaunched, and the singleton is null, restore it. But what would be the good/best/not so sucky way to handle with not-really-persistant-but-it-might-be-nice-to-exist-one-hour kind of object ?

[android-developers] Re: Handling process killed by system
The singletons stick around as long as your process is alive. If your process is killed (and therefore your DalvikVM running your app), nothing sticks around, including your static variables/fields. This is just like any other Java/C/C++ app. The issue is that the OS kills your process, not the user and therefore can be highly unpredictable. That's why your Activities and Fragments have a onSaveInstanceState method.Use this to save your session variables into the provided Bundle and pick them up again from the 'Bundle savedInstanceState' in your Actiivty's/Fragment's onCreate method. If your session variable are complex, let your session objects implement Parcelable, which can be saved properly into Bundles. You could also have them implement Serializable instead, which can be saved to Bundles as well. This'll save you some coding, but is quite bad performance-wise.

Re: [android-developers] Socket Programing
It's not to make you go away, it's just saying: learn to use the
debugger. Once you have something that's going wrong with your
program report back and ask for help.
Otherwise nobody knows what to look for, one person could see the
program works completely fine, one person could see it won't compile!
Give a precise description of what the problem is exactly.
Here's an example:
- I get exception X on line Y which happens when I do Z.

[android-developers] Re: Handling process killed by system
The problem with parcelable and serializable it that it creates new instance of the object for each Activity that is launched. It means that, every time you leave an Activity, to go back for instance, you will have to write the modified object, and check the onActivityResult each time, to update you current version of the session object. It would not really a Singleton anymore, and therefor is probably not the solution for an instance variable... -- -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Handling process killed by system
Your app is stateful (state is carried over from Activity to Activity) and this is indeed an issue you'll run into. If you want to use a static variable (object) for your session state, you'll have to code your own persistence. E.g. Access your (global/static) state through a static method (Factory pattern). If it is not there, read it from a file or database and then return it to the caller. If it is there, just return it to the caller, On an Activity's/Fragment's onSaveInstanceState, call a (global/static) method that will save your current session state to a file or database. Note that saving your session state to a file or database should not happen on the main UI thread. You should do it in a background thread. You could read your most recent session state from a file/database in your Application object's 'onCreate' method. It will start a background thread reading the session state and keep a tally when the session state has been read successfully or not. Your Activities that need the session state could use that tally to show a 'waiting/progress' dialog if the session state is still loading or something similar. If/when the session state is loaded, continue with your Activity's normal functionality.

[android-developers] canvas.drawCircle broken with hardware acceleration on 4.1?
I have been banging my head for a while trying to figure out why my custom
view was not drawing properly until I tried turning off hardware
acceleration.
It is to do with canvas.drawCircle. It is drawn in solid blue at about
300px radius.
I also use canvas.drawText and that works fine under hardware acceleration.
The only thing I can think of is that I a using an unsymmetrical
canvas.scale...
Here is my code:
// Called to redraw the map
@Override
protected void onDraw(Canvas canvas) {
// Check if we are in Eclipse UI editor
if (isInEditMode()) {
return;
}
// Save the canvas' transforms for unscaled UI elements
canvas.save();
// Place the map offset in centre of screen
canvas.translate(getWidth() / 2, getHeight() / 2);
// Zoom the map
canvas.scale((float) (-1.0 / mMapController.getMapMetresPerPixelX()),
(float) (-1.0 / mMapController.getMapMetresPerPixelY()));
// Pan the map
canvas.translate((float) mMapController.getMapCentreX(), (float)
mMapController.getMapCentreY());
// Draw a circle
canvas.drawCircle(0.0f, 0.0f, 0.01f, mCirclePaint);

Re: [android-developers] canvas.drawCircle broken with hardware acceleration on 4.1?
Until 4.2 the hardware accelerated rendering pipeline would render circles
as a texture using the radius you specify in the drawCircle() call. It
would then scale the texture based on the Canvas transform. In this case
you are stretching a picture of a circule that's 1px large, which is why
you are getting a rectangle. Instead of using Canvas.scale(), set the
radius you want directly. Note that we lifted this limitation in 4.2.

[android-developers] heatmap using TileOverlay on Google Maps v2
Hi, I am trying to generate a heatmap, based on a set of LatLng points in Android Maps v2. I am using the algorithm from here: http://blog.furiousbob.com/2011/05/12/heating-up-my-new-xoom-tablet/ I have gone through some examples online, but it uses Overlays which is not just deprecated, but removed from the v2 of Maps API. I have been told that I can achieve the same using TileOverlay, which I would like to try, but am unable to find even a simple example of it, which does not use UrlTileProvider or pre-created set of images. I can use a View to generate the heatmap as a bitmap(via the view canvas), but there dosen't seems to be anyway to map the bitmap to Tiles. PS: Currently, I am placing this view over the map, which needs a lot of re-computations when the map is panned or zoomed, and would want to avoid that. Please let me know if anyone has any recommendations. Best, R -- -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Cross-platform development question
Hi all, This is an interesting question, but a bit of background first...my company has been developing software for almost 30 years now. We have always been a .net house, but now we're creating Android and iOS apps as well. I don't want to have to write business logic and database access logic for each different platform, and since we're doing cloud apps, we should be able to call web services to get and put data into the database. We have been using Entity Framework to communicate with SQL Server for our databases, and, as of late, we have been creating Single Page Applications using Breeze and Knockout. We have created RESTful services using the WebAPI, but in working with Breeze, we like how it calls an IQueryable object. My goal is to write-once, and be able to re-use for the mobile development. LINQ really makes things easier in that we don't have to have a specific API call for each entity, but I haven't found the right library, or I'm not using the right keywords for Google to search...I dunno, but all I'm finding are LINQ libraries that work on data already in memory. That means I will have to bring LOTS of data to the mobile device just to work with it, and that's time-consuming and also will quickly eat up storage space...and why should I do that, when I have a powerful SQL Server that can get me only the data I need. An example: Just about every application starts out showing a list of reecords on a grid. (It would require a query that returns an ID, and one or more descriptive fields (like first and last name).) So we know we can create a RESTful API called getCustomers() and it would return the list for us to populate the grid. Upon selection of an item, we would then want to make another call to the database to populate a detail screen. We could create another RESTful API called getCustomer(id), for example, and it should return the fields that we need to populate the screen. OR we could use the Entity Framework to create a Customers() object, and use LINQ to get what we want from it, just by modifying the calling URLwhich is easy, fun, and cool in the .net environment, and would satisfy my requirements of using the same business code for all platforms. So here's the question: How do you make a call to a RESTful service that returns an iQueryable object from Android (Java)? Is there a Breeze-type of library for Android? What is the best way to do this - create specific RESTful APIs, or is there a way to use this business layer we have already created that's living on the server? -- -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Cross-platform development question
Java is more verbose than C# because it requires a lot of boiler plate to get it to work. If you can make a RESTful Service to return data as XML or JSON, it would be useful.

It's cool to see the Android developers actually read these emails.
