Question

当我尝试在装有Android 28的Pixel 2模拟器上运行Flutter应用程序时遇到此错误。它在前一天工作了，但随后停止了工作。感谢您的帮助。

这是完整的错误消息：

任务'：app：preDebugBuild'的执行失败。 Android依赖项'com.android.support:support-core-utils'对于编译（27.1.1）和运行时（28.0.0-rc01）类路径具有不同的版本。您应该通过DependencyResolution手动设置相同的版本

import concurrent.futures
import urllib.request

URLS = ['http://www.foxnews.com/',
        'http://www.cnn.com/',
        'http://europe.wsj.com/',
        'http://www.bbc.co.uk/',
        'http://some-made-up-domain.com/']

# Retrieve a single page and report the URL and contents
def load_url(url, timeout):
    with urllib.request.urlopen(url, timeout=timeout) as conn:
        return conn.read()

# We can use a with statement to ensure threads are cleaned up promptly
with concurrent.futures.ThreadPoolExecutor(max_workers=5) as executor:
    # Start the load operations and mark each future with its URL
    future_to_url = {executor.submit(load_url, url, 60): url for url in URLS}
    for future in concurrent.futures.as_completed(future_to_url):
        url = future_to_url[future]
        try:
            data = future.result()
        except Exception as exc:
            print('%r generated an exception: %s' % (url, exc))
        else:
            print('%r page is %d bytes' % (url, len(data)))

Android依赖项的编译（27.1.1）和运行时（28.0.0-rc01）版本不同
