Question

This is what I have, but its failing saying that the table does not exists. I am positive it does incase anyone asks that. But this is some of the code that does that:

What gets called

---

/*Constants*/
public static final String AUTHORITY = "content://com.smartcal.eventprovider";
private static final int EVENTS_INFO = 1;
baseUri = Uri.withAppendedPath(baseUri, "events_info");
    return new CursorLoader(this, baseUri, args.getStringArray("projection"), 
            args.getString("selection"), args.getStringArray("selectionArgs"), args.getBoolean("sortOrder") ? args.getString("sortOrder") : null );

---

What matches is

---

private String getTable(Uri uri) {
    String table = "";
    switch(sUriMatcher.match(uri)){
    case EVENTS_INFO: table = "events_info";
    }
    return table;
}

private static final UriMatcher sUriMatcher = new UriMatcher(UriMatcher.NO_MATCH);

static
{
    sUriMatcher.addURI(AUTHORITY, "events_info", 1);

}

---

And my query() method in custom ContentProvider

---

@Override
public Cursor query(Uri uri, String[] projection, String selection,
        String[] selectionArgs, String sortOrder) {
    database = openHelper.getWritableDatabase();

    return database.query(getTable(uri), projection, selection, selectionArgs, null, null, null);
}

Error:

---

06-19 17:34:14.366: E/AndroidRuntime(686): Caused by: 
java.lang.IllegalStateException: Invalid tables

EDIT:

When using Alex’s IllegalArgumentException, this is what I got back from the error:

06-19 19:17:42.277: E/AndroidRuntime(1134): Caused by: 
java.lang.IllegalArgumentException: Unknown URI
content://com.smartcal.eventprovider/events_info

As you can tell, it should match, assuming the sUriMatcher.addURI() method is working correctly.

Answer 1

Your problem might stem from the fact that your code isn’t very well organized…

First thing,

private String getTable(Uri uri) {
    switch(sUriMatcher.match(uri)) {
        case EVENTS_INFO: 
            return "events_info"; // return

        /** PROVIDE A DEFAULT CASE HERE **/
        default:
           // If the URI doesn't match any of the known patterns, throw an exception.
           throw new IllegalArgumentException("Unknown URI " + uri);
    }
}

Second thing,

/** Use constants, not raw ints **/
sUriMatcher.addURI(AUTHORITY, "events_info", EVENT_INFO);

Other than that, you might want to provide some more info.
