Add the Calling and Chat SDKs in an Android application

This article describes how you can integrate the Azure Communication Services Calling SDK and Chat SDK in an Android application.

Problem

With versions of the Calling SDK earlier than 2.11.0, building an Android application with both the Calling and Chat SDKs resulted in the following errors:

Duplicate class com.skype.rt.XXX found in modules jetified-azure-communication-calling-1.2.0-runtime (com.azure.android:azure-communication-calling:1.2.0) and jetified-trouter-client-android-0.1.1-runtime (com.microsoft:trouter-client-android:0.1.1)

2 files found with path 'lib/x86/libc++_shared.so' from inputs: - …\.gradle\...-azure-communication-calling-1.2.0\jni\x86\libc++_shared.so - …\.gradle\...-trouter-client-android-9.1.1\jni\x86\libc++_shared.so

This problem had two causes:

  • Conflicting .jar and .so files included in the Calling SDK package com.azure.android:azure-communication-calling
  • A transitive dependency package that the Chat SDK package com.azure.android:azure-communication-chat imports, com.microsoft:trouter-client-android

Solution

From Calling SDK version 2.11.0 onward, you can integrate both the Calling and Chat SDKs within the same Android application. The 2.11.0 version solved the problem by:

  • Eliminating the conflicting .jar and .so files.
  • Making the Calling SDK rely on the com.microsoft:trouter-client-android package, similar to the Chat SDK's dependency on the Trouter package.

Implementation

Specify the version of the Calling and Chat SDKs for Android in your application's Gradle build file, as shown in this example:

 implementation ('com.azure.android:azure-communication-calling:2.11.0')
 implementation ('com.azure.android:azure-communication-chat:2.0.3') {
     exclude group: 'com.microsoft', module: 'trouter-client-android'
 }

The example uses the latest release version of the Chat SDK package com.azure.android:azure-communication-chat, but you can use any version.

The version of the Trouter package com.microsoft:trouter-client-android that's included with the Chat SDK package com.azure.android:azure-communication-chat needs to be excluded. When the application is built, it will use the Trouter package version included by the Calling SDK package com.azure.android:azure-communication-calling.
