How to build

  • 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 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.

SDK Instructions

  • This version requires the Kotlin SDK for Rocket.Chat. Clone the Kotlin SDK in by running git clone
  • 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 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:
cd Rocket.Chat.Android/app

Note: You need to have Java 8 as default Java for the system (project won't build when using a Java 9+ version).

How to run

Command Line

  • Connect your physical device to your pc via USB or start an emulator. Run adb devices in terminal. You should see your device in the list of devices.
  • In order to build the debug apk, run ./gradlew assembleDebug. This would generate a debug apk which can be found under Rocket.Chat.Android/app/build/outputs/apk/debug folder with the name app-debug.apk.
  • In order to build and install the apk directly to the connected device, run ./gradlew installDebug.

Android Studio

  • After importing the project in Android Studio, go to Run > Run app and then select your device, or create a new virtual device by following the wizard.
