Delete a specific version of Android studio VCs and / or bitbucket

Therefore, I have successfully established a bitbucket repository, submitted multiple versions, and created multiple branches through Android studio. Now, I want to clean up the submissions and branches that are no longer needed. In addition, I want to do this through Android studio rather than the command line. I can see all my versions / branches in the bitbucket and Android studio version control window (alt-9)

I have done a lot of research to complete this seemingly simple task, and there is nothing. Do I need to "delete" in Android studio? In bibucket? All? What about? I may try to do this through trial and error, but understandably, I don't want to screw it up and delete the necessary version. Therefore, I look forward to your guidance

resolvent:

You need to delete the remote branch on bitbucket first, and then delete the local branch in Android studio. The details are as follows:

>Delete useless remote branches in bitbucket. Buy back bitbucket - > branch - > select the branch you want to delete - > click... Button - > delete branch. If you want to delete multiple branches, please do the same

>Get changes from remote to Android studio. Android Studio - > VCs - > git - > get. > delete relevant local branches. Android Studio - > VCs - > git - > branches - > delete branches in local branches tab and remote branches tab
