android-contentprovider

问题 This issue was reported several times, but still not resolved yet. I read all messages/thread which somehow related to this topic either in Samsung's developers site or in StackOverflow Let me again describe whole problem just in few words: Developers used to get list of SMS conversations through simple query like: Uri.parse("content://mms-sms/conversations/"); Cursor cursor = context.getApplicationContext().getContentResolver().query(uri, null, null, null, null); or something like this.

It occupied user RAM space too much. It is recommended to close the SQLiteOpenHelper to solve my problem (it is useful) in post enter link description here. But I want to

问题 The documentation on Android content providers describes using a ContentResolver , obtained from getContentResolver() , to access the content. However there is also a ContentProviderClient , which can be obtained from getContentResolver().acquireContentProviderClient(authority) . It seems to provide more or less the same methods available in the ContentResolver for accessing content from the provider. When should I use a ContentProviderClient instead of just using the ContentResolver directly

问题 I'm building an app where I have a table for events and a table for venues. I want to be able to grant other applications access to this data. I have a few questions related to best practices for this kind of problem. How should I structure the database classes? I currently have classes for EventsDbAdapter and VenuesDbAdapter, which provide the logic for querying each table, while having a separate DbManager (extends SQLiteOpenHelper) for managing database versions, creating/upgrading

问题 I'd like to be able to read the system's SMS content provider. Basically I wanted to make an SMS messaging app, but it would only be useful if I could see past threads etc. It seems like there's a content provider for this, but I can't find documentation for it - anyone know where that is? Thanks -------- edit ----------- Ok I found a way to get the sms inbox provider, and I just dumped all the column names in that provider, looks like this: Uri uriSms = Uri.parse("content://sms/inbox");

问题 I have created a small application, trying to understand the functionality of the LoaderManager and CursorLoader -classes. I have implemented LoaderCallbacks<Cursor> on my FragmentActivity -class and everything works fine, except the fact that when I update my data via ContentResolver.update() or ContentResolver.insert() -methods, onLoadFinished() is not called and as a result my data doesn't update.
