android-contentprovider

I'm trying to implement the second REST client model presented by Virgil Dobjanschi on this video: http://developer.android.com/videos/index.html#v=xHXn3Kg2IQE This is the high level diagram for the model I'm talking about: I implemented everything as suggested, but I have a complex SQLite database model with lots of tables and I need to use transactions to update my local data with brand new data retrieved from server (step 7 in the picture). Are there any suggestions you could make to help me out implement a transactional ContentProvider for this case? Some of you may suggest me to use raw

This is my first time using a content provider but I followed the developer docs but when I run the program it tells me failed to find provider info here is my manifest <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.tyczj.bowling" android:versionCode="1" android:versionName="1.0" > <uses-sdk android:minSdkVersion="11" /> <application android:icon="@drawable/ic_launcher" android:label="@string/app_name" > <activity android:name="Tabs"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER"

I've searched through android's open source code as much as I could and I haven't been able to find the implementation to the actual downloading via the DownloadManager in the 2.3 SDK. I have found the source for the DownloadManager and the source for a download class that has constants to interact with the ContentProvider but I haven't been able to find the source for the ContentProvider . I'm wanting to find this so that I can know a good way to implement a download of my own, since I'll be using a lesser version than 2.3 for my app. Pzanno I was able to find this here . You can also get the

I have a contact ID, how do I get the group the contact is assigned to? I am sure it is something to do with the Contacts.Groups class but I cannot figure it out. In GroupMembership.PERSON_ID you have the ID of the Person, and in the same table GroupMembership.GROUP_ID you have the ID of the group. You can retrieve the groups with the Contacts.Groups . Remember that in every "table" there is and unique ID to identify the row. Hope this helps. (Im working on it too) 来源： https://stackoverflow.com/questions/657154/android-get-group-of-contact-by-id

i want to select unique contacts from android only that contacts which have phone numbers. i am using this code ContentResolver cr = getContentResolver(); Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, ContactsContract.Contacts.DISPLAY_NAME); // Find the ListView resource. mainListView = (ListView) findViewById(R.id.mainListView); // When item is tapped, toggle checked properties of CheckBox and // Planet. mainListView .setOnItemClickListener(new AdapterView.OnItemClickListener() { public void onItemClick(AdapterView<?> parent, View item, int position, long id)

I'm building an Android app with multiple productFlavors , and using Facebook SDK v4.1 for login and sharing contents. The problem is that when I try to install an app on a device which already has the same app installed (but different flavor), it raises an error. It doesn't allow me to install the second app unless I uninstall the existing one. <provider android:authorities="com.facebook.app.FacebookContentProvider{my_app_id}" android:name="com.facebook.FacebookContentProvider" android:exported="true"/> According to this document , the android:authorities should be unique and I should have

I have two pieces of data that need to be accessed from outside applications and stored. According to documentation ContentProviders are the only possible way, but it also mentions external storage. ContentProviders implement a database-like "interface" and using a database would be extremely unnecessary for two pieces of data. I would rather save them to a file, but using a ContentProvider by implementing the abstract methods is problematic because the methods are structured as database queries. I know that there is nothing specifying that ContentProviders must use a database underneath to

I've read all of the documentation online about building search interfaces and adding custom suggestions... but I'm still unclear on how this works. The documentation says that I must "Build a table (such as in an SQLiteDatabase) for your suggestions and format the table with required columns". I'm assuming the system will eventually fill this table with the appropriate suggestions on its own... but which process/class is responsible for this, and when will the actual insertions occur (before any query is made by the user, after a query has been made by the user, etc.)? And while I'm asking a

I have a sqlite database in my application. I want to make an expandable list view with that. I am fixed with the approach I should take for that. Tried a lot to find a tutorial for the same, but could not find a single one, where one is populating the Expandable list with the local database. There is this one tutorial in the android site where they are filling the expandable list with the Contact detail in the phone. They are doing this from the content provider ExpandableList2.java So my question is should I also create a content provider for my database which is inside my own application ?
