To manually install the Signaling SDK for Android, do one of the following:

## Automatically integrate the SDK with Maven Central

1. Open the `settings.gradle` file in the project's root directory and add the Maven Central dependency, if it doesn't already exist:

   ```text
   repositories {
       mavenCentral()
   }
   ```

2. Add the `io.agora.rtm:rtm-sdk` dependency in the `/app/build.gradle` file under your project. Replace `x.y.z` with the SDK version number, such as `2.3.0`. To get the latest version number, see the [Release notes](/en/realtime-media/rtm/reference/release-notes).

   ```text
   dependencies {
       implementation 'io.agora.rtm:rtm-sdk:x.y.z'
   }
   ```

   <CalloutContainer type="info">
     <CalloutDescription>
       To resolve integration issues when co-integrating with the RTC SDK, use `io.agora.rtm:rtm-sdk-lite` instead.
     </CalloutDescription>
   </CalloutContainer>

## Manually copy the SDK files

To manually install the Signaling SDK for Android from a downloaded package:

1. Extract [Signaling SDK](/en/api-reference/sdks?product=signaling\&platform=android) to a local directory, such as `<unzipped_package>`.

2. Copy the following files or folders from the `rtm/sdk` folder of the extracted package to your Android project.

   | File or folder      | Path in your project                  |
   | ------------------- | ------------------------------------- |
   | `agora-rtm-sdk.jar` | `/app/libs/`                          |
   | `/arm64-v8a/`       | `~/app/src/main/jniLibs/arm64-v8a/`   |
   | `/armeabi-v7a/`     | `~/app/src/main/jniLibs/armeabi-v7a/` |
   | `/x86/`             | `~/app/src/main/jniLibs/x86/`         |
   | `/x86_64/`          | `~/app/src/main/jniLibs/x86_64/`      |

   Each architecture folder contains `libagora-rtm-sdk.so` and `libaosl.so`. Copy both.
