Currently, the app is maintained in two branches, namely `v1+` and `v2+`. The `v1+` is maintained in the `develop` branch and the `v2+` is maintained in the `develop-2.x` branch. The older version is written partially in `java` and `kotlin`, but we intend to write the latest version completely in `kotlin`.
Clone the repository by running `git clone https://github.com/RocketChat/Rocket.Chat.Android.git` in your terminal. To build the v1.0+ of the app, run `git checkout develop` and to build the v2.0+, run `git checkout develop-2.x`.
This repository contains all the code related to the Android native application of [Rocket.Chat](https://github.com/RocketChat/Rocket.Chat/#about-rocketchat). To send new pull-requests, always use the branch `develop` as base and open an issue with the description of what you want/need to accomplish, if the issue wasn't created yet.
Since both the versions use `kotlin` for some or all of their classes, following are the common prerequisites for both versions:
## How to build
## How to build
- Android Studio 3.0+ comes with built in kotlin support, so install the latest version (3.0+) of Android Studio (recommended). For older versions, you need to manually install kotlin plugin. Go to `File > Settings > Plugins` and search for `kotlin` and install it. You'll need to restart the IDE in order to see the changes.

- Make sure that you have the latest **gradle** and the **android plugin** versions installed. Go to `File > Project Structure > Project` and make sure that you have the latest versions installed. Refer [this](https://developer.android.com/studio/releases/gradle-plugin.html#updating-gradle) to see the compatible versions.

- Kotlin is already configured in the project. To check, go to `Tools > Kotlin > Configure Kotlin in project`. A message saying kotlin is already configured in the project pops up. You can update kotlin to the latest version by going to `Tools > Kotlin > Configure Kotlin updates` and download the latest version of kotlin.

### Instructions specific to version
### SDK Instructions
#### v1.0+
- After checking out to `develop` branch as mentioned above, simply import the project in Android Studio.
#### v2+
- This version requires the [Kotlin SDK](https://github.com/RocketChat/Rocket.Chat.Kotlin.SDK) for Rocket.Chat. Clone the Kotlin SDK in by running `git clone https://github.com/RocketChat/Rocket.Chat.Kotlin.SDK.git`.
- This version requires the [Kotlin SDK](https://github.com/RocketChat/Rocket.Chat.Kotlin.SDK) for Rocket.Chat. Clone the Kotlin SDK in by running `git clone https://github.com/RocketChat/Rocket.Chat.Kotlin.SDK.git`.
- First, a build is required for the SDK, so that required jar files are generated. Make sure that the android repository and the kotlin sdk have the same immediate parent directory. Change the current directory to `Rocket.Chat.Android/app` and run the `build-sdk.sh` which will result in creating of the required jar file `core*.jar` and `common*.jar` in `Rocket.Chat.Android/app/libs`,by the following steps in your terminal window:
