本文翻译自：ADB Android Device Unauthorized
Since I reinstalled Eclipse (simply deleted and downloaded it again) I can't debug my applications on Samsung Galaxy i9001 (with CyanogenMod - Android 4.4.2).
由于我重新安装了Eclipse（仅删除并再次下载了它），因此无法在Samsung Galaxy i9001（使用CyanogenMod-Android 4.4.2）上调试应用程序。It worked fine before reinstallation.
重新安装之前，它工作正常。Unplug/plug, Uncheck/check "Debug Enabled", adb kill-server/adb start-server, restart phone/computer doesn't work for me.
拔出/插入，取消选中/选中“调试已启用”，adb kill-server / adb启动服务器，重启电话/计算机对我不起作用。On the device authorize dialog never appears (but I remember that dialog appeared before reinstallation).
在设备上，授权对话框永远不会出现（但我记得该对话框是在重新安装之前出现的）。I have no idea how to force this authorize dialog to display.
我不知道如何强制显示此授权对话框。There is no abd_key.pub file in .android directory.
.android目录中没有abd_key.pub文件。When i try read cpu info DDMS says:
当我尝试读取CPU信息时，DDMS会说：[2014-04-15 12:47:06 - DDMS] device unauthorized. Please check the confirmation dialog on your device.
Any ideas?
有任何想法吗？Is it possible to generate keys manually without confirmation dialog?
是否可以在没有确认对话框的情况下手动生成密钥？USB Connection
