My situation is: We have a huge old unformatted codebase that a lot of people have contributed to.
We want to reformat the entire thing, but the problem is, we will lose our entire git history if we do.
It will look like our whole codebase was updated in 2016 by a single user.
My Question is: Are there any plugins in android studio that let the user modify git revision/annotation history settings to ignore specific revision numbers or commits by a certain user and display the revision history from the previous user that edited that line of code?
I've looked all over and haven't found anything so far.
I don't think this is possible.
But what you can do is, if you annotate and see, the line was last changed by that reformat, right click the annotation stuff in the gutter and select Annotate previous revision and you will see the Annotations from the previous revision on in a new Editor.
You did not found answer since it cannot be done
Git is designed in a way that each commit is pointing t its previous one and any attempt to re-write history will result in a rebase.
If you wish to delete certain commits made by user you can do it using filter-branch of BFG but again it will result in rebase.

Let's say I forgot to commit at the moment of compiling my APK.
I continued modifying my files, and then committed later on.
Can I go back to the precise moment of APK compilation, which is unfortunately between two commits?
No, you can't do it - some things you can do is either go back to your old commits and start again(not recommended)or:
If the change was not so large you can see what exactly did you changed and start hard copy-pasting and return to your old version of the code.
But the best thing I can recommend is to use branches - start a production branch(only stable code goes there) and dev branch(in this branch you can modify your code as you want because you have another stable working branch)
Edit: as Zoe mentioned in one of the comments - check for local history in your IDE (the link gives example for android studio IDE)
today it's a shorter question I'd like to ask, to hear your opinions as I suppose some do this differently than others.
First of all,, I have an Android Studio project and am rather a novice on this subject of Android Development. That's why slight changes in the java or xml files could and did make my latest app unstable/ crashing.
Therefore I was asking myself wether Android Studio offers a way to backup stable builds - I could imagine this like a save-as option where you backup the working version and continue working on the the one but have a stable one backed up.
I know there's the export project function but I tried it out a couple of times and having worked on a project on the same device before, prior to reimporting a project causes an error and that's not the way I guess you should handle it in this situation.
I was looking at Google Cloud for using both version control and the option to commit new versions to the trunk and update them at a different location (different device). If that's the solution you propose, I need to look more closely into the documentation to get it up and running (set up the repository already but no clue how to commit changes/ versions).
So, long story short, what tool/ option do you prefer to have an export and a version control option unified for Android Studio?
Interested to hear and thankful for any advice on that!
There are multiple solutions,
Just find your solution/project in your file explorer and back it up, if you need it again just open the project with Android Studio. (not the most popular one)
Use a version control system like git. Link to tutorial (This is the most popular one), If u are unfamiliar with git, just google it and there are tons of examples and documentation. With git you can tag commits and after u mess up revert to the tagged commit
Git is the simpliest.
It's supported by AndroidStudio and later on you can upload your project to GitHub to access it from anywhere.
You can use it with terminal and shorcut keys, incons as well.
You also can make separate branches in order to make and test more versions parallely.
For more info take a look at: https://git-scm.com/about
and of course github: https://github.com/

I am new to Git and do not understand everything yet. I usually commit after each app update and then create a new branch for the next app version, so that I can correct bugs of the currently published version while working on improving the app for future versions.
So far it was just a precaution and I never really used it that way but I want to get serious about Git capabilities. And I face this problem:
I have two branches in addition to the master, and if I compare the files from the two branches, I can clearly see the differences.
However, if I "checkout" from one branch to the other, nothing happens and it seems that the current code is just reassigned to a different branch.
But what I want to do is to be able to modify both codes in parallel.
How does it work?
Thanks.
First you have to do the changes in one branch. Then you can share the same change to other branch using git. There are multiple ways to share the changes, based on the different scenario.
They are "Cherry pick", "patch", "merge" and "stash"(additionally shelve in android-studio).
Based on the scenario shared above, you can use patch to share the code among branches.
Make changes in one branch and commit it.
Right click the commit in android-studio and select "create patch".
Checkout to another branch.
Select options VCS ---> Apply Patch.
Select the "patch" file and apply it.
Now you can able to see the changes you made in the "other branch" in "current branch".
Then you can commit the changes in the regular way.
So I have managed to get a couple apps up on the marketplace only to have a stray thought of what is the best way to go about managing my projects/apps within eclipse to accommodate future updates to the marketplace. My question resides within Eclipse and what to do with my projects/apps as I apply updates.
Do I simply copy my project/app, paste it and the increment the version information accordingly? Or am I continuously working on my published project/app? Or...Is there a recommended/preferred method of going about this. Since they are up and good on the marketplace I am leery of doing something that will cause problems for me later on down the line.
And don't change the package name....correct?
This is what I currently have on the Marketplace...

First of all, everyone's posts were very helpful and I have spent some time looking over documentation through the links provided.
So...and brace for impact as I say this. Being one who has NEVER used any form of SCM for my projects this is all new to me (as everyone's faces cringe), which is why I am asking the original question in the first place. I hate to say tell me anything without doing my research...so within the past few hours using git within eclipse I have gleamed the following:
Team > Share Project ...ignores...any tags(for version info)which is what I am after...commits...THEN
Clone? File -> Import -> Git -> Git Repository at this point once I have cloned my project do I create a new tag with the new version info, and go through the commit process again? If this is the case I now have two items in my Git Repository. One of which has the single tag of 1.0, and the other item which contains two tags 1.0 and 1.1, and when I look at the history I see two tags Version 1.0 and Version 1.1. Then I just switch between the resources I need from within the repository?
I just want to make sure my process is correct before I begin to implement some of this on existing projects that are pretty extensive already. As for the rest I am just going to learn on the fly...branches
You might want to use a revision control system like SVN or git or one of dozens of other options, and continuously update the single project in Eclipse. The benefit of using source control is that you can branch into a new project for major changes, update your existing code for minor changes, and tag the branches so you can revert back to an old snapshot in the future.
I personally use bitbucket which is hosted remotely and is free. It supports SVN and Mercurial.
No, dont change the package name, that will make it new app, instead of upgrade of original.
Use a version control system, like SVN.
Manage Tags for a complete working state of code(through svn), so you can always revert back to that tag.
When ready for new release, increment version no. etc and update on market...
EDIT After addition in question:
Don't get much confused with various GIT/SVN working.. There main purpose is that they will allow you to switch your code back and forth to any point in past, that allows you to code in a way properly knowing that you can always revert back to a Working state.. and it is definitely of much more benefit in a Team , when multiple people are working on same codebase and possibly same files...
Being a long-time user of SVN, I recommend subclipse (svn for eclipse). When you're ready to release another version of your app, create a 'tag' for the release version and you'll always be able to go back to that exact version.
SVN has excellent docs. There is also TortoiseSVN for repo work outside of eclipse.
Does anybody know how to determine whether a certain git commit, for example this one from this issue, was rolled into a particular Android release such as 2.2 Froyo?
Thanks!
My one suggestion is to just look at the shortlog of the appropriate branch (that's froyo-release; I'm guessing froyo is a maintenance branch) and see if the commit's in the shortlog. The commit in question is way, way back - on the 143rd page of the shortlog. I found it just by skipping back until the dates were right. Not very fancy.
I'm guessing this is all you can do with gitweb, though it is under pretty active development, so perhaps someday it'll get that "Branches: " feature from gitk. #Jakub Narebski is fairly active on SO; he might be able to provide a more definitive answer. (not sure if #-notification works in answers or just comments)
