Android 谷歌在iOS和安卓系统之间发送信息
我正试图使用谷歌附近发送消息完全使用超声波（不是BLE或WiFi）。我不知道为什么它不起作用。 我还没有找到任何额外的步骤来完成这项工作 没有错误。日志说发布是成功的。但订户根本没有反应 应用程序是否应该请求麦克风权限？ 应用程序是否应该检查其他内容？ iOS和Android之间是否有现成的超声波信息样本 iOS部分：Android 谷歌在iOS和安卓系统之间发送信息,android,ios,google-nearby,Android,Ios,Google Nearby,我正试图使用谷歌附近发送消息完全使用超声波（不是BLE或WiFi）。我不知道为什么它不起作用。 我还没有找到任何额外的步骤来完成这项工作 没有错误。日志说发布是成功的。但订户根本没有反应 应用程序是否应该请求麦克风权限？ 应用程序是否应该检查其他内容？ iOS和Android之间是否有现成的超声波信息样本 iOS部分： @implementation ViewController { GNSMessageManager *_messageManager; } - (void)viewD

Artur，您需要将发布对象存储在属性或ivar中。只要发布对象存在，发布就处于活动状态。要停止发布，请释放发布对象。订阅也一样
我意识到中的发布/订阅代码示例具有误导性。我会在下一个版本中修复它。当你说它“不起作用”时，你需要更详细地解释到底什么不起作用，你会遇到什么错误，预期的结果以及会发生什么。还有问题发生在哪一行代码。@Emil你是对的。没有错误。日志说发布是成功的。但是订阅者根本没有反应。当你运行应用程序并开始发布/订阅时，你能粘贴你看到的控制台日志消息吗？您已经打开了调试日志记录，所以您应该看到类似以下内容的日志：服务器URL:。。。设备ID:@丹韦伯我添加了日志
