Besides that you miss to provide the error, if the build finished successfully, your problem is probably not Gradle releated and should maybe instead asked in some Android community.

Thank you @Vadim for your quick response. I apologize for failure to provide the error. I was about to do that when I mistakenly hit on enter key from keyboard. I'll update the message with the error now.

Dunno who Vadim is 😄 There should be more information. But as you are using AS, you might easily miss it due to this annoyance: https://youtrack.jetbrains.com/issue/IDEA-226613/Gradle-build-on-failed-build-IDE-auto-focuses-and-shows-incomplete-error-message-which-makes-it-hard-to-understand-why-build 2 so you need to select a higher node in the tree to see the actual error details.

Thanks @Vampire for your quick response. First, I apologize for referring to you as Vadim. My pc was seriously malfunctioning. I highlighted on your name but the system picked the name below your name. I just have to remove the battery and insert it back before the pc started functioning well. Please, accept my apology.🙏

Don't worry. 🙂 It's more an annoyance for wrongly pinged people as they are pinged for threads they are not actually involved in. 🙂
