我试图通过示例应用程序获取和Estimote信标,但无法使其工作。我查看了这两个示例,因为我复制了大部分代码,所以我看不出自己的行为与他们不同。
我正在使用的参考资料:
https://altbeacon.github.io/android-beacon-library/samples.html
让我感到困惑的是,我从我的应用程序中看到了这些奇怪的日志,看起来蓝牙无论出于何种原因都无法正常工作。
我知道UUID是正确的,因为我安装了另一个应用程序可以看到这个完全相同的灯塔没有问题,但是当我厌倦了构建我自己的应用程序时,我无法让它工作。蓝牙绝对开启,无线开启或关闭无关紧要。
我想知道是否有人能发现这个问题,因为我已经尝试过HTC,三星Galaxy S6和S5(Lollipo和Marshmallow)上的代码,它们都显示完全相同的日志。
来自我的应用程序的日志(无法看到信标)

以下是应用中 * WORKS * 的日志(使用相同的手机,信标和操作系统)。看起来我需要在我的应用程序上为蓝牙设置,但我真的不知道它是什么。

答案 0 :(得分:0)
该问题与应用程序被杀并停止从信标扫描有关。

如果我卸载应用程序并重新安装它可以正常工作。有没有更好的方法来解决这个问题?
