[Android] The connection to ADB are down, and a severe error have occured

one. ADB server didn ' t ACK
after configuring the Android environment, when you run the first program, you encounter the following error:
ADB server didn ' t ACK
* Failed to start daemon *
It is possible that port 5037 is occupied and needs to find the PID that occupies the 5037 (android default) port, which is entered in CMD:
Netstat-ano | findstr "5037"
Output process:
TCP 127.0.0.1:5037 0.0.0.0:0 LISTENING 9292
TCP 127.0.0.1:5037 127.0.0.1:49422 established 9292
TCP 127.0.0.1:49422 127.0.0.1:5037 established 3840
At this point the process "9292" ends, the code is as follows:
TASKLIST | findstr "9292"
two. The connection to ADB are down, and a severe error have occured
You may also encounter an error that often occurs after you perform the above results:
The connection to ADB are down, and a severe error has occured.
You must restart ADB and Eclipse.
Please ensure this adb is correctly located at ' D:\. \platform-tools\adb.exe ' and can be executed.
As shown in the following:

The workaround is to call adb kill-server in cmd and then call adb start-server turn on the service. However, errors may occur:
ADB server is an out of date. Killing ...
ADB server didn ' t ACK
* Failed to start daemon *

this is because the port number is occupied, check the pea pod or phone helper occupied port number, will kadb\qadb process is closed.
Here's how:
1. Turn off eclipse and pea pods first, End Process kadb at the same time.

2. Use the CD to go to the Platform-tools folder (containing Adb.exe) and open the ADB service as my instructions are:
G:
CD G:\software\Program Software\android\adt-bundle-windows-x86_64-20140321\sdk\platform-tools
adb start-server
successful output:
        * Daemon not running. Starting it now on port 11888*
        * daemon Started successfully *

Finally click Platform-tools application in Adb.exe folder run the program again.
Note that the above program output port number is 11888, if you are still unsuccessful, you can modify the environment's port number, as follows:

Modify the port number and follow the steps above. This is the wrong solution for configuring android+Eclipse and I hope it works for you ~
