react-native-in-app-update

Google released In App Update feature, but I did not find any react-native supported library for that, so I had to implement it for myself.

How to use ?

1. Open android folder in your react-native project with Android Studio and add implementation 'com.google.android.play:core:1.7.3' at the end of dependencies section of the build.gradle(app) file. Like below,

dependencies {
    implementation fileTree(dir: "libs", include: ["*.jar"])
    //noinspection GradleDynamicVersion
    implementation "com.facebook.react:react-native:+"  // From node_modules


    .......
    implementation 'com.google.android.play:core:1.7.3' // add it at the end
}

Cick sync after adding the dependency.

2. Download InAppUpdateModule.java and InAppUpdatePackage.java files and place in them in the same directory of MainActivity.java(android/app/src/main/java/<package>/)
3. Change the package names in both InAppUpdateModule.java and InAppUpdatePackage.java to your project package name.
4. Now Open MainApplication.java and add our InAppUpdatePackage into getPackages method like below,

        @Override
        protected List<ReactPackage> getPackages() {
          @SuppressWarnings("UnnecessaryLocalVariable")
          List<ReactPackage> packages = new PackageList(this).getPackages();
          // Packages that cannot be autolinked yet can be added manually here, for example:
           //  packages.add(new MyReactNativePackage());
            packages.add(new InAppUpdatePackage());
          return packages;
        }

5. Download InAppUpdate.js and place it into your react-native project.
6. Import the InAppUpdate.js in any js file, wherever you want to use. And use it like below.

  componentDidMount () {
    InAppUpdate.checkUpdate() // this is how you check for update 
  }

7. That's it.

What you should know?

1. It is FLEXIBLE update by dafault, if the user does not update in 5 days, it becomes IMMEDIATE update, you can change the number by editing STALE_DAYS in InAppUpdateModule.java.
2. It does not include prioriy update, you can implement it by editing checkUpdate method in InAppUpdateModule.java. For more details check https://developer.android.com/guide/playcore/in-app-updates#check-priority
