App won't start (error)

[k245sem]

Hello, i have successfully compiled the code but when i try to run the app (i edit configuration) they say no module found so i Googled it and saw to remove apply plugin 'com.android.library' and add 'com.android.application' and the module appeared. Now when i run the app the app does get installed but instead of app name, the package name get's display and when i try to run the app, it stops.
