Build project test Android

I would like a help

Error 1.png occurs when I try to compile a new project and error2.png occurs because I have changed the project name and try to compile again, on the device there is nothing installed with this name.

I have the SDK updated and configured

  • newbie here but encountered similar problem. it was solve when I deleted the whole output folder, and recompile the code.  the output folder is usually the "android" folder found in the same folder where you project is, unless you change the output folder.
