我正在使用所谓的附近连接。一个设备是广告(Nearby.Connections.startAdvertising()),另一个是发现(Nearby.Connections.startDiscovery())。这api工作正常,我可以成功连接到主机设备。但是,如果我断开连接并重新连接几次,则该设备不再进行广告宣传。我正在调用Nearby.Connections.startAdvertising(),但是根本没有调用PendingResult的onResult()方法。从Nearby.Connections.startAdvertising()方法返回PendingResult,您可以使用它来检查广告是否成功启动。有没有人有类似的问题?
我必须重启设备才能让广告重新开始工作。 (重新连接wifi无济于事。)

当您开始投放广告时,您是否设置了超时?您可以尝试在那里设置0:
<?php
//connect to the server
$link = mysql_connect('*****', '*****', '****');
if (!$link) {
die('Could not connect: ' . mysql_error());
}
mysql_select_db('******');
$query = mysql_query("SELECT * FROM tablename");
echo "<table border='1'>
<tr>
<td>Date</td>
<td>Region</td>
<td>Cameraman</td>
<td>Livestream?</td>
<td>Event Title</td>
<td>Lecturer</td>
<td>Time</td>
<td>Speaker</td>
<td>ICE Contact</td>
<td>Venue Address</td>
<td>Venue Contact</td>
<td>Additional Comments</td>
<td>On App?</td>
</tr>";
WHILE($rows = mysql_fetch_array($query)):
$date = $rows['date'];
$region = $rows['region'];
$cameraman = $rows['cameraman'];
$livestream = $rows['livestream'];
$eventtitle = $rows['eventitle'];
$lecturer = $rows['lecturer'];
$time = $rows['time'];
$speaker = $rows['speaker'];
$icecontact = $rows['icecontact'];
$venuecontact = $rows['venueaddress'];
$venuecontact = $rows['venuecontact'];
$additionalcomments = $rows['additionalcomments'];
$onapp = $rows['onapp'];
echo "<tr>";
echo "<td>" . $rows['date'] . "</td>";
echo "<td>" . $rows['region'] . "</td>";
echo "<td>" . $rows['cameraman'] . "</td>";
echo "<td>" . $rows['livestream'] . "</td>";
echo "<td>" . $rows['eventitle'] . "</td>";
echo "<td>" . $rows['lecturer'] . "</td>";
echo "<td>" . $rows['time'] . "</td>";
echo "<td>" . $rows['speaker'] . "</td>";
echo "<td>" . $rows['icecontact'] . "</td>";
echo "<td>" . $rows['venueaddress'] . "</td>";
echo "<td>" . $rows['venuecontact'] . "</td>";
echo "<td>" . $rows['additioncomments'] . "</td>";
echo "<td>" . $rows['onapp'] . "</td>";
echo "</tr>";
echo "</table>";
endwhile;
?>
在附近的连接快速入门示例中,您可以设置以下两个变量:
Nearby.Connections.startAdvertising(mGoogleApiClient, hostNameString, appMetadata, 0l, this);

如果您不需要,我建议不要继续广告您的连接。
我建议您在开始会话时使用stopAdvertising()
,当您需要重新连接时,只需再次发送主机ConnectionRequest(...)
而不做广告。
无论如何你需要它,你可以再次打开它。
如果你愿意,你可以试试
stopAdvertising()
然后startAdvertising(...)
,看看它是否有效,因为我使用的是这种方法,而且效果很好。
希望有所帮助
