I was wondering if a custom sync adapter would be appropriate when syncing "normal" application data that is tied to a Google account. For example, I'd like to sync some data to a Google docs spreadsheet in this case. Would a sync adapter be the right choice for this use case or should I handle the sync in the app?

I'm making an Android Java app game (although this question applies to all languages really) and hope to release the first version soon. I'm nervous about how I save data in my game. My problem is that, if in a later update, I decide to store more data or store the same data in a different way, I need to be careful I don't lose or corrupt data for users that upgrade (i.e. I want users to be able to use data created by an old version in the new version, like their high scores from before).For example, say I want to save high scores in version 1.
View 3 Replies View RelatedI've implemented a SyncAdapter correctly registered through the application manifest which allows to sync contacts with our backend. The sync requests are correctly sent to the SyncAdapter but actually I have a couple of dubts:
1) How a client (the object which calls requestSync of a specific authority) can be notified about the current status of the sync request, e.g. if the request has been correctly performed, is still pending, or is aborted for any reason?
2) I saw the addStatusChangeListener method in ContentResolver class but there is no documentation about that. Can someone clarify the correct usage of this? What kind of events can I listen?
3) What is the SyncContext ??
Onother issue is that after I've added my custom account to the device I saw that when the user selects to add a contact to that account, only the name fields are present in the "new contact" activity, no phones emails etc. Can someone tell me if (and how) it is possible to show all the standard fields that are actually showed to the user, even if no accounts exist on the device?
I'm trying to use AccountManager to store account information and have implemented an authenticator, but I keep getting exceptions like the below that crash the phone. Comparing with sample code this seems to be because I don't have (or particularly want) a SyncAdapter and associated service. Is there a trick to using AccountManager without adding a SyncAdapter?
CODE:.................
What we are doing currently? We have some structured, textual data on a server which is exposed using web services(RESTful). My application polls this server regularly(AlarmManagerService) to fetch the data and save it on local database(sqlite). Also, a user is authenticated and authorized beforehand for access.
Questions: There is a SyncAdapter/AccountManager class in the SDK and I was wondering if it can be of any use in my application to achieve the syncing mentioned above? If yes, what sort of infrastructure is needed at back end to support a sync set up using this adapter? Links to articles etc. that give details of using this adapter and other info is appreciated.
I have written a SyncAdapter that takes a "com.google" account and performs a sync with an appengine web service. Testing this with the dev tools sync tester (on the emulator), this sync appears to work just fine.
The problem is, it's not syncing by default. And going to the account in "accounts & sync" shows my google account to be blank - as if there's no sync services available.
I suspect that in order to get my sync shown in the "accounts & sync" menu, I'd need to implement my own AccountAuthenticator that would do exactly the same thing as what I presume google's AccountAuthenticator must already do. This is not an exciting job, and it seems very unnecessary. So:
Is there a way to add an entry to the "accounts & sync" menu that uses my SyncAdapter but relies on a google account? or to add a sub-menu to google accounts that enables sync of my appengine service? if not,is there a way I can re-use google's AccountAuthenticator from within an AccountAuthenticator I write?
Actually i tried the SampleSyncAdapter (Sample Sync Adapter examples), its working fine for me. but i am not able to edit/delete the synced contacts. Is this possible to edit those contacts ? please let me know.

The account appears in account and sync, but when I try to select the account for syncing, I am getting a hard database error. I am trying to figure if this error is on mobile or the app engine. Further, what can be causing this error. Another error that I am getting is failed to find provider info.

View 2 Replies View RelatedIts really obnoxious. It doesn't matter if make sure and unselect 'sync music' and only have one particular podcast checked, it will sync everything. All podcasts, entire music library, everytime. I cant for the life of me figure out what I'm doing wrong and its pretty damn annoying because of how much longer it takes to do it, when really if it would sync just what I wanted it to, it would take less than 5 minutes. At least WinAMP is out and perhaps will be a better solution than this buggy app Doubletwist. This is my last time dealing with it unless I find a home-run solution.

View 1 Replies View Relatedto start with I've gone through the entire notepad tutorial, I'm a professional game programmer who has some extra time. (though most of my time has been in C++, I did take a year or two of Java classes in college, and remember some of it). I'm not sure the site is a good site to ask questions like this.. If someone has a Forum that might be a good place to ask these newbie questions, please feel free to point me in the direction. I've examined a few of the samples, and think I've a grasp of what I want to do. I've a three to four project plan for some Android releases to sharpen my skills, but since this is my first project and I have never really developed for a mobile phone or the android before, I'd like to make sure I have a solid plan.The first project is an example of the license plate game, however I want to do a few things to change it. Heck maybe when I'm done it'll become a bingo style game, with bluetooth connectivity, you never know. The base idea is I want to offer a list of states, with checkboxes next to them. so to do this, I'll be starting with a Linear List layout similar to the note pad example, and then have a row that is only a Checkbox. I can use text and call strike through if it's been checked off. Perhaps offer an option to not show them if they are checked.
But I want the list to be generated from a set of lists. Maybe all of America's states, maybe reasonable American states (no Hawaii, no Alaska) maybe a North American list, (add in Mexico and some Canadian provinces), a European list, who knows. I'd probably have to have a pop up window that lists all of the lists I suppose using a radiogroup of some sort. So then as far as the data, after weighing options I think best solution is to make a database with two fields, "checked" and "name".I figure I can use the menu for most of the user interaction (aside from clicking on stuff we want to check off) with maybe a few context menu items, I understand how to make all of those already so I should be good. The question I have is what is the best way to populate the lists? Should I create raw data, and have different files for all the lists? Or is there some other way to do this? I've seen this done on the searchable dictionary, but I'd like to hear what people who have actually generated the data like this before. In addition is there an easy way to look at the sql database these applications create, or do you have to run searches on them and output the data? Finally any other suggestion or advice? I definitely want to try to get something like this on the market so I can see the full life cycle and see if anyone actually likes it. (luckily there's not a plethora of them already) but I also want a few people to look over my code if they're willing when I'm done to make sure I've done this right or at least not missing any basic mistakes.
I've used the search and read all thread that include "data" in the post's title. Lots of it was helpful, yet I have a few questions. This morning as a test to see how much data my phone uses just for syncing and any kind of background data, I turned on the network data and syncing.
after 20 mins it was up to 1.5mb (according to my data counter widget). I downloaded the Spare Parts app which shows me what instances use how much data; very useful. The 1.5mb I'm stating here already exclude RSS updates and a few web pages I loaded this morning. This 1.5mb is ONLY the syncing stuff. So my question is: Why and how can it be so much data? I use gmail and google calendar and contacts, and have some 400+ friends of Facebook (FB). Calendar and FB were already synced yesterday before I went to bed. How can another sync use so much data? It wasn't my email (Gmail) as there weren't many this morning.
The calendar sync apprently took up 468kb, and a process called "UID 10027" which i presume is FB? used 555kb. I'm really puzzled by these numbers. as google sync happens frequently throughout the day unless I activate it, usually i get up to 15mb a day without actually doing much (i.e. no browsing, no RSS feeds updates, no streaming). Why is the FB and Google sync taking up so much data? I downloaded FB for android, which replaced the FB for HTC application (so now I have inbox, and not the stupid "Take a Picture" in the app thank god) which doesn't even use the sync from the account settings but has its own update cycle which I had turned to 'manual'. Ialready switched off the "use WiFi for location" because I heard google maps otherwise constantly searches in the background
I have recently bought a HTC One X and find it difficult to keep my Moto xoom and One X in real time sync for Apps and App data.
I have been through many apps and none are quick, easy and not internet hogging junk.
Now its not like iCloud where you download an app on one device and gets automatically pushed to your other devices quick and easy.
I know I'm not the only one with two or more Android devices and I want know how you keep your devices in sync?
I want to add a flag that will tell how much time my application is running. This flag will have to stay even after the application is removed. And, if its installed back, i must have a way to recover this flag. What's a way to implement this?
View 8 Replies View RelatedI've tried to see if others have had data problems like mine, but apparently no one has posted on something of my magnitude.
I have 1 Gb of data a month...thats one of the biggest plans in Canada, and I cannot increase (student plan maximum). A few weeks ago, my 3G watchdog alerted me that I was over my 1Gb, and this was in a week span of a new billing cycle. I called Telus and they said it was a mistake, but later on my data usage on their site said I had used 500 Mb on that day!
Since then I had a few more instances where 400 or 500 Mb has been used on a day (almost all outgoing or transmitting data). This has to be a syncing problem or a bug. Not only do I not stream radio or youtube, but I usually only use facebook, twitter, read yahoo email, and weather updates.
I had to get a datablock for the rest of the billing month (since I had used up 2.2 Gb in 10 days) and now I'm monitoring my data wifi usage through data counter widget.
It would be wonderful if I could figure out what app is sucking all of my data...I have about 500 friends on facebook...I also went though and deleted almost all of my emails in my inbox (which was the problem with motorola data usage).
Yesterday, I was on the net on postsecret, and then on facebook (maybe 15 minutes total). Upon returning I saw I had used 510 Mb of transmitting data....
The only advice I got from Telus is to format my phone and start over...No other problems with the HTC desire have been reported to my provider.
I have a Galaxy S4 (rooted) and just bought a Galaxy Tab Pro 10.1 (Afraid to root because I don't want to loose warranty)
I restored all my apps on my tablet but all my Angry Birds, Plants vs Zombies and all other game data is missing from the tablet.
First, is there a way to restore this game data to the tablet WITHOUT root?
Preferably, I would like to seamlessly sync the game data between the 2 devices. It would be great to play a level of any game on my phone and then pick up at the same spot on my tablet. Is this possible?
I have an issue with my Gmail app where I think no information is being 'sent' from the phone. I receive incoming mails, but no mails are sent. Though I delete incoming mails, the next notification which I receive when I get the next mail will show "17 mails" though I would have deleted the previous 16 emails. When I check email on my browser, all the emails what I had deleted are still there. I have tried a factory reset and I still have a problem.

If we reinstall the application , android preserves the data of old application .So now application finds the file on local system and does not download it from FTP server. But it should always download the file on first execution after fresh install. Is there any way to completely wipe out the previous application data on fresh install?

talk about limited information! I'm trying to get my Android application to connect to an online database to access information. There's quite a bit of info including geotags and these are going to be mapped on my app. The developer site has the very informative piece of information:You can use the network (when it's available) to store and retrieve data on your own web-based services.

View 10 Replies View RelatedI have an AppWidget which provides a summary of some data stored and controlled by my main Application. (In a similar way to a Calendar AppWidget showing the next event from the main Calendar application). I want to know the best practice for retrieving the data to update my widget. I have followed the example, and I have extended AppWidgetProvider and have a working widget, onto which I can update. I would expect to read the data from my main application and then update it via my AppWidgetProvider's onUpdate() routine.
Now, is the best practice here for my separate main application to provide the data via a ContentProvider? I assume so, as my Appwidget is not part of the same application. Is it possible to access a ContentProvider inside my onUpdate() routine? Before writing my main application content provider I started to test out retrieving some available data like Contacts information, and showing say a contact name in my widget, to show I can extract data from an existing ContentProvider. When accessing the Contacts contentprovider, the examples talk about:
1) Activity.managedQuery(), but my AppWidget is not an activity. 2) ContentResolver.query(), but I can't work out how to get a valid ContentResolver so I can access the Contacts. getContentResolver() does not appear to be defined for AppWidgetProviders. Am I approaching this the correct way?
There is no solution for this?
