Uri Matcher不匹配uri

Question

这是我的Uri Matcher

static UriMatcher buildUriMatcher() {
    UriMatcher mUriMatcher = new UriMatcher(UriMatcher.NO_MATCH);

    // Bind uriMatcher int constants and uris
    mUriMatcher.addURI(OneSpaceContract.CONTENT_AUTHORITY, OneSpaceContract.PATH_DRIVE, DRIVE_LIST);
    mUriMatcher.addURI(OneSpaceContract.CONTENT_AUTHORITY, OneSpaceContract.PATH_DRIVE + "/#", DRIVE_ID);
    mUriMatcher.addURI(OneSpaceContract.CONTENT_AUTHORITY, OneSpaceContract.PATH_FILE, FILE_LIST);
    mUriMatcher.addURI(OneSpaceContract.CONTENT_AUTHORITY, OneSpaceContract.PATH_FILE + "/*", FILE_ID);
    mUriMatcher.addURI(OneSpaceContract.CONTENT_AUTHORITY, OneSpaceContract.PATH_FILE + "/drive/#", FILE_LIST_WITH_DRIVE_ID);
    mUriMatcher.addURI(OneSpaceContract.CONTENT_AUTHORITY, OneSpaceContract.PATH_FILE + "/file/*", FILE_LIST_WITH_FOLDER_ID);
    mUriMatcher.addURI(OneSpaceContract.CONTENT_AUTHORITY, OneSpaceContract.PATH_FILE + "/drive/#/*", FILE_LIST_WITH_DRIVE_ID_AND_FOLDER_ID);

    // Return the new matcher!
    return mUriMatcher;
}

这是PATH_FILE常数

 public static final String PATH_FILE = "file";

UriMatcher和我的uri不匹配

Uri：content://olexiimuraviov.ua.onespace_diplomaproject/file/drive/11/root

这里有一个例外

java.lang.UnsupportedOperationException: 
    Unknown uri: content://olexiimuraviov.ua.onespace_diplomaproject/file/drive/11/root
    at OneSpaceProvider.query(...)

我试着调试却一无所获。Uri模式看起来很好，给定uri也很好，但是matcher不匹配它。你能帮我解决这个问题吗？提前感谢！

正如Selvin在他的例子中指出的，有问题的规则是绑定FILE_ID的规则，段的第一部分匹配，所以它不会尝试在该段中找到任何匹配的规则。把那条规则移到最后，那就没问题了。
