I had the same problem with the android@5.1.1 version. I solved this issue, checking what version of android is provided by cordova. You can check it in C:/Users/%USER%/.cordova/lib/npm-cache/cordova-android
我对android@5.1.1版本有同样的问题。我解决了这个问题，检查了cordova提供的android版本。您可以在C：/ Users /％USER％/。cordova / lib / npm-cache / cordova-android中查看它
Then, you install the android platform version provided. For me it was @5.1.0 which was in my cordova-android folder. So I used the cmd line following:

you can check the android version provided by cordova by typing cordova platform ls inside projectname/cordova folder. I refered from below url https://cordova.apache.org/docs/en/latest/guide/platforms/android/.
(For me .cordova/lib folder was empty).
你可以通过在projectname / cordova文件夹中键入cordova platform ls来检查cordova提供的android版本。我在下面提到了网址https://cordova.apache.org/docs/en/latest/guide/platforms/android/。 （对我来说.cordova / lib文件夹是空的）。
Then add that platform from inside project's cordova folder by executing cordova platform add android@5.1.1 (in my case, solved the issue).
然后通过执行cordova平台添加android@5.1.1（在我的情况下，解决了问题）从项目的cordova文件夹中添加该平台。
