How to use a library project in android studio

Question

I have been trying to add this library project to my existing project in Android Studio. It's the first time I am going to use a library project and I am having tough time. I have looked around for many ways to do this from tutorials and posts around but couldn't get it done.

Accepted Answer

I'm not sure if it's already possible to add a library project via the IDE (-> without any problems). I do this by configuring the gradle files of my project like this:

- create a folder in your root project directory named `libs`

- copy the folder `datetimepicker-library` to `libs`

add this library in your `settings.gradle` with the following command:

```
include ':libs:datetimepicker-library'
```

go to your `build.gradle` file of your `AppProject` and add the following line to your `dependencies`:

```
implementation project(':libs:datetimepicker-library')
```

at least you have to sync your gradle files: Tools -> Android -> Sync Project with Gradle Files

Please try this. If you get errors please post the log file.
