android-contentprovider

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. I have a custom ContentProvider and I am wondering if the problem is in my ContentProvider

问题 I'm developing an application where I need to insert lots of Contact entries. At the current time approx 600 contacts with a total of 6000 phone numbers. The biggest contact has 1800 phone numbers. Status as of today is that I have created a custom Account to hold the Contacts, so the user can select to see the contact in the Contacts view. But the insertion of the contacts is painfully slow. I insert the contacts using ContentResolver.applyBatch. I've tried with different sizes of the

问题 I am trying to implement the Content-Provider-Sync Adapter pattern as discussed at Google IO - slide 26. My content provider is working, and my sync works when I trigger it from the Dev Tools Sync Tester application, however when I call ContentResolver.requestSync(account, authority, bundle) from my ContentProvider, my sync is never triggered. ContentResolver.requestSync( account, AUTHORITY, new Bundle()); Edit -- added manifest snippet My manifest xml contains: <service android:name=".sync

问题 Why Content Provider is not considered as Data storage option in android Data Storage Options in Android and where do content providers store their data ? 回答1: They are considered different to the other because they provide a way to globally share data between applications. The other data storage options are private to that application. As for where they store their data: From the docs: "How a content provider actually stores its data under the covers is up to its designer." 来源： https:/

问题 I have been struggling with a unit testing problem on Android for a while now. My app uses a Sqlite DB to store details on vehicles. I have recently added the ContentProvider pattern to retrieve the data (the database used to be accessed directly). The app works fine, but my tests sporadically fail when run in 'run' mode on eclipse - they pass in 'debug' mode. In my setUp() method, I create a RenamingDelegatingContext in order to create a test version of my database. All this does is prefix

问题 I need to fetch and list the received emails in my own layout listview. Is this possible through Content Provider? 回答1: There are no documented and supported content providers for "received emails".

There are probably hundreds of email clients, only a few of which might have such

问题 Since android wear and mobile are two separate devices, is the wear device able to access a public content provider from a custom app that's on the mobile once it is connected? Thanks. edit: if you downvote, pls comment why, as your downvotes don't help me understand anything. edit2: Ok, let me explain a little more.
