[android-developers] Data readable by two apps
Hi! Is it possible to share files between two apps? My scenario is this: I want to create a free/demo version of my game and a complete version. The player should be able to play the free version, then upgrade to the complete and continue where the free version ended - ie. the complete version would need to load a savegame created by the free version.

[android-developers] Re: Intents problem
You may want to update your intent with the latest app state just before the user leaves your application. That way your onResume will work with the most up-to-date intent: Either the one from updated by your widget or the one updated by your app itself.

When I click in a button on my widget, it sends an intent to my application main activity, that handles it and shows a dialog. My problem is that if I go to another application, alternate between applications, go to home screen and back -- if my application is not in foreground -- and I go back to her, the old intent that my widget sent to my activity is handled again and suddenly a dialog is shown. The intent is handled using onResume, to handle the cases where the application was just created and when the application is restarted by widget, but also happens when user comes back to it.

AFAIK, you only have 1 *active* conection at a time. wireless or 3g, in order of preference. if none is available you only have a loopback interface up (127.0.0.1) that doesn't connect you to anything except you phone :) Is an application, for example the browser only ever connected to one ip address? Or can it be connected to multiple addresses for each radio such as gprs or wifi (wlan)? Only one. Can an application decide which connection to open a socket to? For example can I create an application and decide whether to connect the socket to the wlan or gprs? Or does the OS decide? The OS decides. An application developer only have to worry about being able to use the Internet. nothing else. Finally how do native applications handle connectivity? In the same manner?

[android-developers] SQLite concurrent access best practices
Hi, I have an application with several tables, each being updated by AsyncTask fired by different Activities and used by UI with SimpleCursorAdapter. Though i am not developping a game, I would like to avoid to interrupt the user as mush as possible. Has SQLite is not multiaccess proof, what is the best way of handling such situation? - I consider adding lock from each DB open and to each close sequence but this seems quite subject to bugs - The solution i am using now is that each DB access (read/write) is done in UI thread (when AsyncTask completes, DB write is done typically in onPostExecute), but that means user is blocked for several seconds during the DB write. Is there any better solution for that? Should i use a ContentProvider? when i read Content providers store and retrieve data and make it accessible to all applications, this does not seems to be what i need. Any idea? -- Thierry. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Which device is best for testing development?
Right now, the Droid is probably the least expensive development phone you can get. There are hundreds available on e-Bay for around $250-300. One of the most popular devices out there now for Android is the Droid, so if you're going to develop for the masses, then the Droid (or the Milestone as a GSM version) is the device to have. Many of the devs who received a Droid in the Market seeding program are selling or have already sold their phones, the US based attendees for Google IO received Droids as well and a lot of those people will be selling them also. I have two of them myself and ATT as my carrier so they can only be used as development devices... want to buy one? -John Coryat -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] ViewFlipper bug in APILevels7
Symptom: the ViewFlipper starts flipping views in an irregular pattern, much faster than the flipinterval set. Cause: calling stopFlipping() / startFlipping() successively in intervals less than the flipInterval results in the FLIP_MSG message being submitted in the ViewFlipper's handler repeatedly, putting the flipper in a totally FUBAR state, switching to the next child earlier than it should. I am mad at whoever wrote the ViewFlipper.java code found in SDK1.5, 1.6 (merged into AOSP under the anonymous initial-contribution email), since ITS BUGGY and it cost me an awful lot of time debugging my own code, thinking I am doing something wrong! I would also like to THANK Jeff Sharkey for fixing this code in his 1162fd77a8ff8467c96204c00bcaf941aef6aa85 patch. Too bad we cant rely on the fixed code if we want to support devices with android 1.5/1.6 as well. -szabolcs -- You received this message because you are subscribed to the Google Groups Android Developers group.

Your list view will be backed by some adapter, containing the information you're displaying (including the names) yes? So you have the checked item positions - which pretty much tells you exactly which objects you need to get from your adapter which should have the names you're interested in. - TreKing - Chicago transit tracking app for Android-powered devices http://sites.google.com/site/rezmobileapps/treking -- You received this message because you are subscribed to the Google Groups Android Developers group.

OK! -Can I do everything in one single activity or should I do an activity for the search, one for the result list, one for the restaurant description, and another for the map? A MapActivity is required to use MapView, so you need at least that. You almost definitely want to break apart your app in separate, logical units represented by activities, where each is something your app does. Your search and results list could probably go in one activity, the details could be another, and the map a third. -Would doing one single activity make the application more responsive? No. -How can I use a list and a map within a normal activity (without ListActivity and MapActivity)? You can't, again, the MapView requires MapActivity. Though you can probably put a ListView in a MapActivity with it's MapView, but that would probably look weird.

On Fri, May 7, 2010 at 1:14 AM, kevin0228ca kevin022...@gmail.com wrote: which phone is good for testing? or is emulator good enough? For development, the emulator should be good enough to make an app, though you'll definitely want to test it on devices. It's great to have a Droid or other popular / powerful phone, but don't forget that many many people are still on older devices and older platform versions. So one could argue that the best device is the oldest, crappiest, slowest phone that is still in active use (G1 FTW!) so you can code your game as efficiently as possible and have it run on old hardware. Then you can pretty much assume it will run brilliantly on any more powerful phone after that. - TreKing - Chicago transit tracking app for Android-powered devices http://sites.google.com/site/rezmobileapps/treking -- You received this message because you are subscribed to the Google Groups Android Developers group.

For insert() and update(), have it under synchronized blocks.

Has SQLite is not multiaccess proof, what is the best way of handling such situation? - I consider adding lock from each DB open and to each close sequence but this seems quite subject to bugs - The solution i am using now is that each DB access (read/write) is done in UI thread (when AsyncTask completes, DB write is done typically in onPostExecute), but that means user is blocked for several seconds during the DB write. Is there any better solution for that? Should i use a ContentProvider? when i read Content providers store and retrieve data and make it accessible to all applications, this does not seems to be what i need.
