React Native OkHttp Version Conflict with Android AWS Amplify for Brownfield RN Android App

[shishirchulliyil]

Description

This issue is reproduceable and uses React Native 0.78.2.

We’re building a brownfield Android app using React Native (0.78.2) alongside native Android modules. Our app requires:

• React Native (0.78.2): Internally depends on OkHttp 4.9.2 for all Android networking.
• AWS Amplify Android SDK (2.27.1): Requires OkHttp 5.0.0-alpha.11 (or higher).

Problem:
When making API calls from React Native screens, the Android native layer’s OkHttp version is used. This leads to a dependency conflict (detailed error log mentioned at the bottom):

• OkHttp 4.9.2 (required by React Native) and OkHttp 5.x (required by AWS Amplify 2.27.1) are incompatible.

Forcing the build to use one version breaks the other:

• Forcing OkHttp 4.9.2: Breaks AWS Amplify 2.27.1 (missing APIs, build errors).
• Forcing OkHttp 5.x: Breaks React Native networking (incompatible APIs, runtime errors).

Root Cause:
Both React Native and AWS Amplify require different, incompatible OkHttp versions, but only one version can be present in the final APK. This makes it impossible to use both stacks together without conflict.

Impact:

• Cannot use both React Native 0.78.2 and AWS Amplify Android 2.27.1 in the same app.
• API calls from React Native screens fail due to OkHttp version mismatches.
• Gradle dependency resolution fails, or runtime crashes occur.

Ask:
Is there any plan or technical possibility for React Native to upgrade OkHttp from 4.9.2 to 5.0.0+ in the Android Gradle build?

Steps to reproduce

1. Install react native template for brownfield app from the community repo : https://github.com/react-native-community/template/tree/0.78-stable/template
2. For /android/gradle/libs.versions.toml I have this configured for my existing android app:

awsAppSync = "3.4.2"
awsAppSyncRuntime = "3.4.2"
awsSdkClient = "2.78.0"
awsAmplifyCognito = "2.27.1"
awsAmplify = "2.27.1"
amplifyAwsApi = "2.27.1"

3. For react-native part, I have these packages configured in my package.json to make graphql api calls.

 "@aws-crypto/sha256-js": "^5.2.0",
 "@aws-sdk/client-cognito-identity": "^3.840.0",
 "react": "19.0.0",
 "react-native": "0.78.2",

4. When the API call initiates within react native part, the existing android app crashes with the log shared in the description section.

Copying my response from here: react-native-community/template#164

AWS Amplify Android SDK (2.27.1): Requires OkHttp 5.0.0-alpha.11 (or higher).

This is clearly a problem of AWS Amplify. Why do they hard require OkHTTP 5?
By requiring OkHTTP they're effectively breaking the whole RN ecosystem.

Have you opened an issue against them? If yes, please link it there.

Also, what is the incompatibility you're talking about.
Can you share the build failure?
