Include a module from other repo in a android gradle project

### Creating repositories with submodules
#### Adding a submodule to a Git repository and tracking a branch

If you add a submodule, you can specify which branch should be tracked via the -b parameter of the submodule add command. The git submodule init command creates the local configuration file for the submodules, if this configuration does not exist.

# add submodule and define the master branch as the one you want to track
```
git submodule add -b master [URL to Git repo] 
git submodule init 
```
first command it adds a new submodule to an existing Git repository and defines that the master branch should be tracked
second command initializes submodule configuration


## Cloning a repository that contains submodules

If you want to clone a repository including its submodules you can use the --recursive parameter.

`git clone --recursive [URL to Git repo]`

If you already have cloned a repository and now want to load it’s submodules you have to use submodule update.

```
git submodule update --init
# if there are nested submodules:
git submodule update --init --recursive
```

### Including the subfolder as module in root/settings.gradle
```
include ':A'
include ':B'
project(':moudle').projectDir = file("another-repo/module")
```
