This android SDK requires Android developer Toolkit version 255.0.0 or abve.

Updated recentlyAndroid
SDKAn error similar to the problem occurs when eclipse is started. However, I just wantRestoreTo the original development environment. So I found this article. The method is valid !!!

WindowsInstall the android virtual machine below. Sometimes, after you select to update the SDK, point to android_sdk_windows_x86 in eclipse preference. A prompt such as this androidsdk requires Android developer Toolkit version already 0.0or above is displayed, and the VM cannot be opened.Android_sdk_windows/tools/libUnder
Plugin. Prop FileIs changed

# Begin plugin. Prop
Plugin. Version =255.0.0
# End plugin. Prop

Eclipse sees plugin when viewing this file. version = 255.0.0, the current SDK requires plug-ins later than version 20.00, but the current ADT plug-in has not been updated to version 0.0, but we only want to use the old plug-in, the simplest method is to add the plug-in. the version information is changed to the version number of the old version, for example, the current ADT is 16.0.0. the current SDK version has been updated to version 0.0. After I update it by mistake, I am prompted to update the android developer toolkit to version 0.0.0 or later, and the earlier version of Android developer
Toolkit cannot be used, and the problem is found only after the file is found. Modify plugin. version = 16.0.0 (my old Android developer Toolkit) is saved. Restart eclipse to use the old AVD.
