当我安装 Ubuntu SDK 和模拟器时，只出现黑屏 - 模拟器日志显示：

有没有人成功设置过模拟器？一般不建议在设备上安装 Ubuntu 进行调试，就像 Android 的情况一样？如果是这样，哪款手机支持得最好？
更新-2：
一定是我没有重启某个服务 - 再次安装 ppa 后，下次启动似乎已经修复了这个问题。不幸的是，帐户选项卡似乎不起作用，并且无法连接到 Ubuntu One - 这显然是使用应用程序安装程序所必需的。
这只是一个错误，还是 Ubuntu 手机会像 Android 一样，需要许可才能使用 repo？
桌面版 Ubuntu 商店不需要账户，这只是对 Ubuntu-touch 预发布的限制吗？
答案1
我也没有成功运行过模拟器，所以我无法帮助你，但就调试而言，是的，最好在手机上调试。
至于设备，最好使用 Canonical 官方支持的硬件。您可以找到受支持设备的列表这里。
