android-contentprovider

According to Android documentation : android:multiprocess Whether or not an instance of the content provider can be created in every client process — "true" if instances can run in multiple processes, and "false" if not. The default value is "false". Normally, a content provider is instantiated in the process of the application that defined it. However, if this flag is set to "true", the system can create an instance in every process where there's a client that wants to interact with it, thus avoiding the overhead of interprocess communication. Therefore, if this attribute is set to true then

I have seen some other questions about this, but none of the answers really seemed to work for my code. I'm getting a 'SQLiteConstraintException: error code 19: constraint failed' error when I try to insert into my DB. Here is the code for the insert operation. db.insert returns a -1 right now, which leads to the "failed to insert" message. Here is the the relevant Content Provider code: public static final String PROVIDER_NAME = "com.oliverapps.provider.DB"; public static final Uri CONTENT_URI = Uri.parse("content://"+ PROVIDER_NAME + "/tasks"); public static final String _ID = "_id"; public

We run into the following crash when we attempt to query "content://mms-sms/conversations/" on a Samsung Galaxy S3 (Android 4.0.4) running on the Sprint network. Our calling code: Uri uri = Uri.parse("content://mms-sms/conversations/"); Log.e("IL", "CONTENT MIME " + context.getApplicationContext().getContentResolver().getType(uri)); // The next call crashes... Cursor cursor = context.getApplicationContext().getContentResolver().query(uri, null, null, null, null); The interesting fact is that the log above returns CONTENT MIME vnd.android-dir/mms-sms as expected. Stack trace below: Caused by:

Android's Content Provider must have : At least one authority must be specified. So for example in Google's samples android-BasicSyncAdapter AndroidManifest.xml there is <provider android:name=".provider.FeedProvider" android:authorities="com.example.android.basicsyncadapter" android:exported="false" /> Then to implement this CP one need to define the same String inside the CP like in android-BasicSyncAdapter FeedProvider.java CONTENT_AUTHORITY public static final String CONTENT_AUTHORITY = "com.example.android.basicsyncadapter"; As we have to define this String twice, isn't this basically

Hi this is my code to get the words from the user dictionary. this is my code but i am not able to run it... private String getwordlist() { String[] mSelectionArgs={""}; String[] mProjection ={UserDictionary.Words._ID, UserDictionary.Words.WORD, UserDictionary.Words.FREQUENCY}; String mSelectionClause = null; String mSortOrder = null; mCursor = getContentResolver().query( UserDictionary.Words.CONTENT_URI, // The content URI of the words table mProjection, // The columns to return for each row mSelectionClause, // Either null, or the word the user entered mSelectionArgs, // Either empty, or the

I'm learning about custom providers and loaders. As a simple example I'm trying to implement a GridView that shows the pictures stored in the external SD card. Although I've read a lot (documentation, threads on SO, Google groups, forums...) I'm not able to get my code working. I know that several issues may be present on this example but I want to go step by step. The first error stopping the code is a NullPointerException , so my question is how to fix it. This is a minimal version of my Activity (it uses support library v4): public class MainActivity extends FragmentActivity implements
