REACT NATIVE 0.74.3 Signed Release APK: No cached version available for offline mode

Welcome to our comprehensive guide on resolving the “No cached version available for offline mode” issue in React Native 0.74.3 signed release APK. This error can be frustrating, especially when you’re trying to deploy your app to the Google Play Store. Fear not, dear developer, for we’ve got you covered!

Understanding the Issue

The “No cached version available for offline mode” error occurs when React Native’s bundler is unable to find a cached version of your app’s JavaScript bundle. This typically happens when you’re trying to generate a signed release APK for your app.

But why does this happen? Well, it’s because React Native’s bundler is designed to work in online mode by default. When you’re generating a signed release APK, you’re essentially telling React Native to work in offline mode. And that’s where the trouble begins!

Step-by-Step Solution

Don’t worry, we’ve got a solution for you! Follow these steps to resolve the “No cached version available for offline mode” issue in React Native 0.74.3 signed release APK:

1. Update your `react-native` version to the latest (0.74.3 or higher) by running the following command:

   npm install react-native@latest

2. Open your `android/app/build.gradle` file and add the following code:

   android {
     ...
     defaultConfig {
       ...
       bundlertasks {
         bundleReleaseJsAndAssets {
           inputs.files fileTree(dir: 'src/main/jsbundle')
           outputs.dir file('src/main/assets')
         }
       }
     }
     ...
   }

3. Create a new file called `bundle-config.js` in your project’s root directory with the following code:

   module.exports = {
     // Enable bundling in offline mode
     offline: true,
   };

4. Update your `android/app/build.gradle` file to include the new `bundle-config.js` file:

   android {
     ...
     defaultConfig {
       ...
       bundlertasks {
         bundleReleaseJsAndAssets {
           inputs.files fileTree(dir: 'src/main/jsbundle')
           outputs.dir file('src/main/assets')
           // Add this line
           config file('bundle-config.js')
         }
       }
     }
     ...
   }

5. Run the following command to generate a signed release APK:

   cd android && ./gradlew assembleRelease

Understanding the Solution

So, what’s happening behind the scenes? Let’s break it down:

• We updated our `react-native` version to the latest (0.74.3 or higher) to ensure we have the latest bundler version.

• We added a new task to our `android/app/build.gradle` file to enable bundling in offline mode. This task uses the `bundleReleaseJsAndAssets` configuration to generate a JavaScript bundle in offline mode.

• We created a new `bundle-config.js` file to enable bundling in offline mode. This file is used by the React Native bundler to configure the bundling process.

• We updated our `android/app/build.gradle` file to include the new `bundle-config.js` file. This ensures that the bundler uses the correct configuration when generating the signed release APK.

• Finally, we ran the `assembleRelease` command to generate a signed release APK using the updated configuration.

Troubleshooting Common Issues

While following the above steps should resolve the “No cached version available for offline mode” issue, you might encounter some common issues. Here are some troubleshooting tips to help you out:

Issue	Solution
Failed to generate JavaScript bundle	Check your `bundle-config.js` file for syntax errors. Make sure the file is in the correct location and is being referenced correctly in your `android/app/build.gradle` file.
APK generation fails with an error	Check your `android/app/build.gradle` file for syntax errors. Make sure you’ve updated the `bundlertasks` configuration correctly.
Bundle size is too large	Optimize your JavaScript code by reducing unnecessary dependencies and compressing your code using tools like Brotli or Gzip.

Conclusion

And that’s it! You should now have a signed release APK for your React Native 0.74.3 app. Remember to update your `react-native` version, add the necessary configuration to your `android/app/build.gradle` file, and create a new `bundle-config.js` file to enable bundling in offline mode.
