本文翻譯自：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).
由于我重新安裝了Eclipse（僅删除并再次下載下傳了它），是以無法在Samsung Galaxy i9001（使用CyanogenMod-Android 4.4.2）上調試應用程式。It worked fine before reinstallation.
重新安裝之前，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，取消選中/選中“調試已啟用”，adb kill-server / adb啟動伺服器，重新開機電話/計算機對我不起作用。On the device authorize dialog never appears (but I remember that dialog appeared before reinstallation).
在裝置上，授權對話框永遠不會出現（但我記得該對話框是在重新安裝之前出現的）。I have no idea how to force this authorize dialog to display.
我不知道如何強制顯示此授權對話框。There is no abd_key.pub file in .android directory.
.android目錄中沒有abd_key.pub檔案。When i try read cpu info DDMS says:
當我嘗試讀取CPU資訊時，DDMS會說：[2014-04-15 12:47:06 - DDMS] device unauthorized. Please check the confirmation dialog on your device.
Any ideas?
有任何想法嗎？Is it possible to generate keys manually without confirmation dialog?
是否可以在沒有确認對話框的情況下手動生成密鑰？USB Connection

Ohhh finally I figured it out!

It's likely that the device is no longer authorized on ADB for whatever reason.
無論出于何種原因，都有可能不再在ADB上授權該裝置。1. Check if authorized:
1.檢查是否經過授權：<ANDROID_SDK_HOME>\platform-tools>adb devices
List of devices attached
4df798d76f98cf6d unauthorized
2. Revoke USB Debugging on phone
2.撤銷手機上的USB調試If the device is shown as unauthorized , go to the developer options on the phone and click "Revoke USB debugging authorization" (tested with JellyBean & Samsung GalaxyIII).
如果該裝置顯示為未授權 ，請轉到手機上的開發人員選項，然後單擊“撤銷USB調試授權” （已認證JellyBean和Samsung GalaxyIII測試）。3. Restart ADB Server:
3.重新啟動ADB伺服器：Then restarted adb server
然後重新開機adb伺服器adb kill-server
adb start-server
4. Reconnect the device
4.重新連接配接裝置The device will ask if you are agree to connect the computer id.
裝置将詢問您是否同意連接配接計算機ID。You need to confirm it.
