# Adding Modules from source

## iOS

To add an iOS module from source, do the following. 

1. Unzip the module archive to a known location on your system. We will use the path to the module folder later
2. Add  the licensing pod to your Podspec:

```
    pod "Licensing", :path => "Path to module folder"
```

3\. Add the module pod:

```
 pod "MessageModules/StickerMessage", :path => "Path to module folder"
 pod "MessageModules/VideoMessage", :path => "Path to module folder"
 pod "MessageModules/AudioMessage", :path => "Path to module folder"
 pod "MessageModules/KeyboardOverlayOptions", :path => "Path to module folder"
 pod "MessageModules/FileMessage", :path => "Path to module folder"
    
 pod "FirebaseModules/FirebaseBlocking", :path => "Path to module folder"
 pod "FirebaseModules/FirebaseLastOnline", :path => "Path to module folder"
 pod "FirebaseModules/FirebaseTypingIndicator", :path => "Path to module folder"
 pod "FirebaseModules/FirebaseReadReceipts", :path => "Path to module folder"
 pod "FirebaseNearbyUsersModule/FirebaseNearbyUsers", :path => "Path to module folder"

 pod "ContactBookModule/ContactBook", :path => "Path to module folder"
 pod "EncryptionModule/Encryption", :path => "Path to module folder"

 pod "ChatSDKXMPP/XMPPAdapter", :path => "Path to module folder"
 pod "ChatSDKXMPP/XMPPReadReceipts", :path => "Path to module folder"
```

4\. Run pod install\
5\. Import the module in your app delegate:

```
import MessageModules
import FirebaseModules
import ContactBookModule
...
```

6\. Enable the module:

```
let modules = [
    // Other ChatSDK dependencies
    ...
    BBlockingModule.init(),
    BReadReceiptsModule.init(),
    BTypingIndicatorModule.init(),
    BLastOnlineModule.init(),
    StickerMessageModule.shared(),
    BVideoMessageModule.init(),
    FileMessageModule.init(),
    BContactBookModule.init(),
    BAudioMessageModule.init(),
    BKeyboardOverlayOptionsModule.init(),
    BNearbyUsersModule.shared(),
    EncryptionModule.init(),
]
```

## Android

1. Unzip the archive to a known location
2. Open Android Studio
3. Click File -> New -> Import Module
4. Select the module directory
5. Enable the module. In your main application class add:

```
ChatSDK.builder()
    ...
    build()
    .addModule(FirebaseEncryptionModule.shared())
    .addModule(ContactBookModule.shared())
    .addModule(FileMessageModule.shared())
    .addModule(AudioMessageModule.shared())
    .addModule(StickerMessageModule.shared())
    .addModule(VideoMessageModule.shared())
    .addModule(FirebaseBlockingModule.shared())
    .addModule(FirebaseLastOnlineModule.shared())
    .addModule(FirebaseNearbyUsersModule.builder().build())
    .addModule(FirebaseReadReceiptsModule.shared())
    .addModule(FirebaseTypingIndicatorModule.shared())
    .build().activate...
```
