Building on apk show success message. But apk not create . Why?

Hi dear,

As you suggest I removed the platform and re-add make the solution. In my case the problem is I install Platform first and then Plugins . But for working it must be in opposte i.e
Must install plugin first and then platform

The problem : Build done but could not see apk .why? is another one , no relation with it…

Thanks alot @uddyvky
