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
