• Code analysis

Code path: \Application\src\main\java\com\example\android\storageprovider\MyCloudProvider.java

public Cursor queryRecentDocuments(String rootId, String[] projection)
        throws FileNotFoundException {
    ......
    // Create a queue to store the most recent documents, which orders by last modified.
    PriorityQueue<File> lastModifiedFiles = new PriorityQueue<File>(5, new Comparator<File>() {
        public int compare(File i, File j) {
            return Long.compare(i.lastModified(), j.lastModified());
        }
    });
    ......
    // Add the most recent files to the cursor, not exceeding the max number of results.
    for (int i = 0; i < Math.min(MAX_LAST_MODIFIED + 1, lastModifiedFiles.size()); i++) {
        final File file = lastModifiedFiles.remove();
        includeFile(result, null, file);
    }
    return result;
}

In for code segment, lastModifiedFiles.remove() will modify PriorityQueue size, so lastModifiedFiles.size() always change, this is logic error.
