Android – urimatcher mismatch
•
Android
It works! I'm not sure what has changed. I do use GIT. I've been looking at my submission and code for hours
Because the title indicates that my URI matcher stopped matching
Below I pasted the relevant section of my content provider
public class Provider extends ContentProvider {
private static final String TAG = "Provider";
private static final String SCHEME = ContentResolver.SCHEME_CONTENT;
private static final String AUTHORITY = "com.snot.bodyweightworkout.database.provider";
private static final String BASE_URI = SCHEME + AUTHORITY;
public static final Uri URI_EXERCISES = Uri.parse(BASE_URI + "/exercise");
public static final Uri URI_PROGRAMS = Uri.parse(BASE_URI + "/program");
public static final Uri URI_PROGRAM_EXERCISES = Uri.parse(BASE_URI + "/program/#/exercise");
private static final int EXERCISE = 1;
private static final int EXERCISES = 2;
private static final int PROGRAM = 3;
private static final int PROGRAMS = 4;
private static final int PROGRAM_EXERCISES = 5;
private static final UriMatcher sURIMatcher = new UriMatcher(UriMatcher.NO_MATCH);
static
{
sURIMatcher.addURI(AUTHORITY, "/exercise", EXERCISES);
sURIMatcher.addURI(AUTHORITY, "/exercise/#", EXERCISE);
sURIMatcher.addURI(AUTHORITY, "/program", PROGRAMS);
sURIMatcher.addURI(AUTHORITY, "/program/#", PROGRAM);
sURIMatcher.addURI(AUTHORITY, "/program/#/exercise", PROGRAM_EXERCISES);
}
…
Then there is the part that should be actually matched
@Override
public Cursor query(Uri uri, String[] projection, String selection, String[] selectionArgs, String sortOrder) {
Log.v(TAG, "URI: " + uri);
Cursor result = null;
int match = sURIMatcher.match(uri);
switch(match)
{
case PROGRAMS:
result = DatabaseHandler
.getInstance(getContext())
.getReadableDatabase()
.query(Program.TABLE_NAME, Program.FIELDS, null, null, null, null, null, null);
result.setNotificationUri(getContext().getContentResolver(), URI_PROGRAMS);
break;
case PROGRAM:
final long pid = Long.parseLong(uri.getLastPathSegment());
result = DatabaseHandler
.getInstance(getContext())
.getReadableDatabase()
.query(Program.TABLE_NAME, Program.FIELDS,
Program.COL_ID + " IS ?",
new String[] { String.valueOf(pid) }, null, null, null, null);
result.setNotificationUri(getContext().getContentResolver(), URI_PROGRAMS);
break;
...
default:
throw new UnsupportedOperationException("Unmatched(" + match + ") URI: " + uri.toString());
I'm trying to query with a cursor loader like this:
getLoaderManager().initLoader(0, null, new LoaderManager.LoaderCallbacks<Cursor>() {
@Override
public Loader<Cursor> onCreateLoader(int id, Bundle args) {
return new CursorLoader(getActivity(), Provider.URI_PROGRAMS, Program.FIELDS, null, null, null);
}
Every violation will be hit. The mismatch is that I finally use FC and the following lines in my log
E/AndroidRuntime( 1979): Caused by: java.lang.UnsupportedOperationException: Unmatched(-1) URI: content://com.snot.bodyweightworkout.database.provider/program
I've been starring here for several hours. I really need some fresh eyes to aim at it. Therefore, if some soul can take a look, I will be very grateful. Thank you in advance
There is no need to start /, so define your adduri () method call as follows:
static {
sURIMatcher.addURI(AUTHORITY, "exercise", EXERCISES);
sURIMatcher.addURI(AUTHORITY, "exercise/#", EXERCISE);
sURIMatcher.addURI(AUTHORITY, "program", PROGRAMS);
sURIMatcher.addURI(AUTHORITY, "program/#", PROGRAM);
sURIMatcher.addURI(AUTHORITY, "program/#/exercise", PROGRAM_EXERCISES);
}
