android-contentprovider

If I call to a ContentProvider from a Activity, which thread is ContentProvider running in? E.g. What happens if the Activity is killed and a query is executing in the ContentProvider? Say that you have a slow network query f.ex. If you mean the normal use case of using a ContentResolver to call a ContentProvider then here is what happens according to the best of my knowledge: I am assuming in this example that your ContentProvider lives in one process and your Activity in another process. If the ContentProvider has not been created then the onCreate() method is called using the "main" thread

I've watched the Google I/O REST talk and read the slides: http://www.google.com/events/io/2010/sessions/developing-RESTful-android-apps.html I'm still a bit unclear on how to nicely handle, say, an update error thrown by the remote server. I have implemented my own ContentProvider and SyncAdapter. Consider this scenario: Update a user's Contact Details via REST call: Request an update using a ContentResolver. My ContentProvider immediately updates the app's local Sqlite database and requests a Sync (as per recommendations in the Google I/O talk). My SyncAdapter.onPerformSync() is called and

I need to get all phone contacts and their email address and photo uri: This is what am doing: private void getContacts() { ContentResolver cr = getContentResolver(); Cursor cur = cr.query(Contacts.CONTENT_URI, null, null, null, Contacts.DISPLAY_NAME); if (cur.getCount() > 0) { while (cur.moveToNext()) { // if // (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) // > 0) { Contact contact = new Contact(); String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID)); Uri uri = getContactPhotoUri(Long.parseLong(id)); // set photoUri

After watching the very known video on this topic I decided to go with design pattern B. Using a contentprovider with servicehelper. Basically I have the following files: MyProvider MyDatabase Mycontract In the activity I can now get the contentresolver and query the provider. All is working great so far. Now I need to sync my contentprovider to fetch data from my REST API. Thus I need to implement a service helper service and Rest method. Studying the Google IO app has helped me a lot, I'm a novice with Android so it's still hard to figure it out. I see Google uses RemoteHandlers to process

What is difference between ContentObserver and DatasetObserver ? When one or another should be used? I get Cursor with single row. I want to be notified about data changes - eg. when row is updated. Which observer class should I register? If you are using a ContentProvider (via ContentResolver or Activity.managedQuery() ) to get your data, simply attach a ContentObserver to your Cursor . The code in onChange() will be called whenever the ContentResolver broadcasts a notification for the Uri associated with your cursor. Cursor myCursor = managedQuery(myUri, projection, where, whereArgs, sortBy)

Yesterday I posted a similar question on why my code started on my content provider class rather than the main class and I've gotten some feedback which I've updated but the problem still remains where the code starts with the ContentProvider class rather than the main class. I've run through the code with debugger and its puzzling why the code starts in the Content Provider and passes back to the main class at the Context stage. I hope to solicit some help here ! The main class is here: public class MedF1 extends Activity { /** Called when the activity is first created. */ @Override public

first I want to say I'm new at android, so I'm apologizing if the question is to stupid. I'm writting a Content Provider for a SQLite database with two tables. On table is to show a list at a navigation-drawer activity and the second table is to show in a ListFragment. Everytime when I'm starting the app I'm getting an SQLException. 10-07 15:30:33.856 28280-28813/de.schmidt.android.passworttresor E/SQLiteLog: (1) near "table": syntax error 10-07 15:30:33.871 28280-28813/de.schmidt.android.passworttresor E/AndroidRuntime: FATAL EXCEPTION: ModernAsyncTask #1 10-07 15:30:33.871 28280-28813/de
