In a new Android Studio project, when I view Project Structure, there are 2 modules. One is "ProjectName" and the other is "ProjectName-ProjectName". Did I do something wrong when creating the project?
When creating new projects, we always create a top level project with a single module in it.
Studio or IntelliJ will show both in the module list but the top one ("testing") doesn't output anyway.
We do this instead of a flat structure in the root project, so that it will allow you later to easily add new modules (like libraries) without having to convert the structure of your project.
what matters is the "testing-testing" module (we'll probably rename this "testing-main" at some point). the other module doesn't do anything. If you look at its build.gradle it's empty, while the other one declares an Android project.
I got a similar set of .iml files as yours, using an older version of Android Studio, but after upgrading to a later version it created yet another .iml, so then there was a top-level project.iml with a module containing module.iml and module-module.iml.
As far as I could tell, the module-module.iml file was useless, and the key information was in module.iml. However, even if I deleted all the iml files, Android Studio would recreate all of them, so I realized it was storing enough information in the [project]/.idea/modules.xml to recreate the iml files from scratch.
So I exited Android Studio, deleted the .idea folder and the .iml files, then relaunched Android Studio and imported the project using the build.gradle files. It recreated only project.iml and module.iml, and everyone is happy.
SUMMARY:
As long as your gradle.build files are clean, then you can delete the .idea and .iml files, import the project using the gradle files, and get a nice clean project structure.

I try to build and run the sample helloworld/mobile in project (https://github.com/android/car-samples)
My question is about how to select the sample app directory as described in README.md:
Select a sample app directory (e.g. helloworld/mobile) in the Project Structure UI on the top left. Each sample app has two build targets, one for the mobile platform and the other for the automotive platform.
<<<<
I went through Project Structure UI, I tried different possibilities but no way,
Build menu always shows Make Module car-simples-main and when I launch Make Module, nothing happens.
Wondering if something has changed in the last Android Studio version,
I use Android Studio Chipmunk | 2021.2.1 Patch 1
Anyone can help?
Thanks.
First of all, let's understand how the git directory is structured.
The directory has the two folders car-lib/CarGearViewerKotlin and car_app_library, which are gradle projects that can be built using gradle.
How do you know?
Any folder contains gradle wrapper and a build.gradle and settings.gradle files means that they're ready to be built using gradle, and these can contain modules inside of them.
Now helloworld/mobile is a module, or you can view it as a sub-project.
How do you know?
If you open up the parent's settings.gradle file, you will see the line include ':helloworld:mobile' meaning that the directory helloworld/mobile is a sub-project or module for the top level car_app_library project.
Modules by themselves are not runnable, they need to be contained in a parent project with top-level gradle files.
Now the solution for your problem should be: open up these two as projects in Android studio individually: car-lib/CarGearViewerKotlin and car_app_library, it will create a default run configuration for each project.
You won't be able to run helloworld/mobile alone, you'll need to run the parent project car-samples/car_app_library.
However, You should technically be able to open the root directory (the git directory containing all of the projects) and creating a run configurations by hand for each project, and you should be able to run the projects using one Android Studio window opened.
Am not getting gradle file in the Android project as it is unavailable in android studio bt is available in project file folder. I tried a lot to resolve this issue but I failed.
Thanks in Advance
The project thinks it's still a non-Gradle based project; it's not the presence of the build.gradle file that makes it Gradle-based, but it's how the project was set up in the first place. You'll need to re-import your project to finish the conversion to Gradle.
First, though, it looks like you don't have a settings.gradle file; it looks like you need one. Since you've set up your project as a single-module project, then you can put the file in your project's root directory, next to build.gradle. It should contain this:
import ':'
In the future if you add more modules to your project you may want to convert it to a multi-module directory structure, but you don't need to worry about that now. In any event, now you need to do the re-import in Android Studio:
Close your project
Back up your project
Delete the .idea folder in the root directory of the project
Delete all the .iml files in your project
Import your project in Android Studio, and in the dialog that prompts you for a file, choose the build.gradle file.
After this, you should be good to go.
I have facing an exact same situation in past, I solved this error by following step
First of all I would remove following files/directories from your project-folder:
bin/
build/
.idea/
.gradle/
projectname.iml
when you open android studio import your project
I just downloaded a project from GitHub to learn from those that know better; Image 1. After extracting the project and importing it to my android studio, it gave me "migrate project to gradle" error.
I have imported using gradle but to no avail.
This is the screenshot of my studio:

I'm new on Android Studio, and I'm still learning to importing libs and modules.
The thing is I have created my project as usual but in some point I lost the "project" gradle file and no I have only modules.
I wonder why none of gradle files have the "Project" word. In fact I'm interesting in the file build.gradle (Module:Swipe) to (Project:Swipe)
Question
How can I set the file build.gradle (Module:Swipe) changes to (Project:Swipe)
Not sure I understand your question...
It seems like you are missing the Project gradle file. I dont know what caused that.
To add a new one, just copy one from another project and edit it (it needs to be located on the project folder)
*Maybe it will be easier on the project pane. see here how to change to project panel:

I use the wizard to create a new Android project in Eclipse Juno with Android SDK Tools revision 20.0.3 at build SDK 15 and minimum required SDK 15. The files are generated with sample code for activity, manifest, etc. I have tried different templates (like MasterDetail or BlankActivity with Tabs) in this process and there are sometimes issues such as AndroidManifest.xml or activity_main.xml with repeated XML elements. So I fix these issues manually (which I think is a bug with the wizard).
Now, I want to "team share" the project via EGIT. So I right-click the project and "Team->Share Project->git". At this point, it wants me to choose a repository. I have created a new one outside Eclipse workspace (and re-used it once created). (I also tried creating one in the parent directory (i.e. in workspace despite an Eclipse warning not to do so).
Either way, when the share operation completes, the buildpath for Libraries "Android Dependencies" does not have the "android-support-v4.jar" in the location specified which was in the workspace. It seems that after the egit operation, the project directory appears to have been moved to the repository, but the .classpath file has not changed.
Is this how egit should work (move project workspace inside git repo and tell Eclipse that the project directory is in a new location)? Is the only workaround to fix the buildpath manually?
Is there a different approach to create new android project in Eclipse and then put the relevant files (i.e. exclude generated java files) into a local git repository such that Eclipse EGIT works?
I am answering my own question after some trial and error.
Here are the steps.
Create the android project via the wizard.
Fix any XML errors (as necessary) to get a buildable project.
Right-click project and Team->Share Project->Git
Select the Git Repository (and create if necessary).
At this point, the Android Dependencies (a dynamic classpath container) in the Java Build Path will be wrong because Git has moved the files to the repository.
Close the project (Project->Close Project)
Re-open project (Project->Open Project)
Now, the Android Dependencies are correct because it is dynamic. I don't know the exact mechanism used by Eclipse for dynamic classpath container, but if you read the Android Tools website it will explain the rules used to to populate this container.
Clean the project. (Project->Clean...)
The important thing is not to try to fix these Android Dependencies yourself (like deleting it), because then your Android project may have issues when you start to build the APK.
