我正在尝试使用 Google PLACES API 获取附近地点的结果。我已将 API 回调嵌入到我的地图活动顶部的搜索栏。当我继续在搜索栏上输入时，应该会出现建议。建议将显示为一个列表，我可以从中选择一个地点并使用该地点的坐标继续我的逻辑是否有更简单的方法来实现此功能？我的查询始终默认为 API 异常失败。
这是我的逻辑输出

该错误表明 API 密钥无效，这是不正确的，因为当我使用我的 API 密钥执行 Web 查询时，我得到了结果。
解决方案
您收到的错误表明问题出在您的 API 密钥上。首先，仔细检查您是否正确添加了 API 密钥，密钥两端没有任何空格或多余字符。
其次，确保它受到适当的限制；它需要是Android 限制为您的应用程序的包名称和指纹。如果您还添加了 API 限制，请检查是否列出了 Places API。出于测试目的，您可能还想暂时完全取消限制，然后测试“地点自动完成”是否与不受限制的键一起使用。
希望这对你有帮助！
