我的firebase监听器在iOS（设备和模拟器）和Android模拟器上工作得非常好

当连接到真正的android设备时，监听器有时不会启动

我如何进行调试

当firebase侦听器不工作时，firebase auth（）函数仍在工作。因此，我可以对用户进行身份验证，但无法使用侦听器上的检索数据

比如说,

firebase.auth().signInAndRetrieveDataWithEmailAndPassword(email, pass)
.then(() => {
    console.log('this prints every time');
})
.catch(function (error) {
    console.log(error);
});

firebase.auth().onAuthStateChanged((user) => {
    if (user) {
        firebase.database().ref().on('value', (snapshot) => {
            console.log('This never prints')
        });
    }
}
侦听器上的.on不会启动，但是身份验证工作

这种情况有时会发生，通常要等上几个小时，然后再试一次，这样就不会发生了。然后它又会回来

编辑：在应用程序打开的情况下等待了一个多小时后，firebase侦听器实际上工作了。但是，花了一个多小时。仍然不知道为什么…

安全规则是否需要身份验证才能以您显示的方式访问数据库？是的，需要身份验证。但是，在我的实际代码中，我用firebase.auth（）.onAuthStateChanged（（用户）=>{/.on listener here}）包装了firebase侦听器。我还在我的帖子中添加了一些额外的细节。我能想到的唯一区别是auth数据通过常规HTTPS请求，而实时数据库的流量通过（web）传输套接字。你是否在防火墙或代理之后，这可能会影响流量？这可能是值得的，并检查logcat的输出，以提示连接问题的原因。我用logcat的输出更新了我的帖子。这是在全新的Alcatel CameoX w/Android 7.0设备上运行的。此外，当我切换到移动热点wifi时，问题em消失了。这表明我的互联网出现了问题，但在iOS设备上，这个问题没有发生。很明显，Android出现了问题。我看到你得到了一个超时。增加timout值，或者在出现超时时尝试建立重试逻辑。
