[2010-03-11 09:36:56-helloopone] You must restart ADB and Eclipse.
[2010-03-11 09:36:56-helloopone] Please ensure the ADB is correctly located at ' D:\OPhoneSDK_1.5
\platform-tools\adb.exe ' and can be executed.

Solve:

Method 1.cmd in ADB kill-server, then Adb-startserver
Method 2. Method 1 kills Adb.exe in Task Manager and then restarts Eclipse.
Method 3. Methods 1 and 2 do not work, then see the last sentence in the error: whether there are adb.exe in the Platform-tools (my mistake is not platform-tools folder under the relevant path)
, so I chose to create a new folder and copy all the files in the tools to Platform-tools.

4. Before the method tried or not, it is recommended to reinstall a system, preferably a different system.
