國外有大神已經總結得比較全面
Try below steps:
- Close the Eclipse if running
- Go to the Android SDK tools directory in Command Prompt
- type
adb kill-server - then type
adb start-server - No error message is thrown while starting ADB server, then adb is started successfully.
- Now you can start Eclipse again.
it worked for me this way, Eclipse should be closed before issuing these commands.
前提是你的adb已經配置好了。 如果這時候依然didn't ACK,那麼啓動任務管理器，看看是否有adb.exe.有的話關掉，再重複以上動作就可以了。
還有一個比較容易忽視的很重要的問題，就是打開taskmanager的時候，並沒有adb.exe，如果這時候你認爲絕對不是adb的問題你就錯了。cmd打開dos，輸入adb kill-server,這個時候才能真正保證kill掉了adb.exe。
