运行一个示例android项目

Question

When I download an Android project, I don't know how I can run it. As an example I've downloaded this project

When I open it Android Studio says that:

After clicking the Configure button I see only:

After clicking OK button, I can see the project structure and there is no any error.

However, I cannot build or run this project.

How can I do this?

Thank you very much for your time and assistance in this matter.

Answer 1

Some Projects given by the guides are older and donnt have the gradle configuration to run properly on the newest version of Android Studio.

The recommendation is never try to open in a normal way!!. You need import all the projects that you download, in that way Android Studio check and override configurations in project to run/Build properly.

I try import this porject and is working fine. All you need to do is Import and accept the sugestion that Android Studio popup to Update gradle.

EDIT:

You can import in 2 ways.

Important !! Select folder project.

First window to select Project in AS.

And the other way is when you have open the project just go File>New>Import Project

Answer 2

This is probably because you have not yet told Android Studio what to run/how to run. Go to run->run...->app and then you will have to select an emulation device to run it on.

Answer 3

Restart android studio and Import the project OR give a try to these steps:

1. press CTRL+ALT+SHIFT+S .
2. Under Project Setting go to Facets .
3. Click + button and add Android-gradle .
4. select your project name. click apply and ok.
5. close your project and reopen.
