好奇怪。我一直在用虚拟设备模拟器进行测试，效果很好。（在 Mac 迷你电脑上）
然后我带了一个真正的安卓设备来测试应用程序——虽然应用程序在真实设备上运行良好，但它突然在模拟器上停止工作。 它可以正常启动和构建，但是当我尝试在模拟器上登录应用程序时，它没有正确登录，它说登录失败（尽管登录是正确的并且可以在真实设备上登录）。
我看到一个有类似问题的帖子，它说要增加内存/存储，所以我尝试了，但结果相同。
这是什么原因造成的？ 如何让模拟器再次正常运行？提前致谢。
这是Logcat:(如果你注意到尴尬的空格，请忽略-我出于安全原因去掉了目录名)
更新：已解决。首先，第一次，输入用户 ID 插槽突然出现了用户 ID 的“多行” - 所以我（cmd A）选择了所有，删除以清除它。 以及我的一位同事登录，并且有一项安全措施，即只有一台设备可以登录该帐户。
