Android: Linking to your gradle Project

• Add following lines into android/settings.gradle

include ':RCTHttpCache'
project(':RCTHttpCache').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-http-cache/android')

• Add following lines into your android/app/build.gradle in section dependencies

...
dependencies {
   ...
   compile project(':RCTHttpCache')    // Add this line only.
}

• Add following lines into MainActivity.java

...
import cn.reactnative.httpcache.HttpCachePackage;
      // Add this line before public class MainActivity

public class MainActivity extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        ...
        mReactInstanceManager = ReactInstanceManager.builder()
            .setApplication(getApplication())
            .setBundleAssetName("index.android.bundle")
            .setJSMainModuleName("index.android")
            .addPackage(new MainReactPackage())
            .addPackage(new HttpCachePackage())        // Add this line
            .setUseDeveloperSupport(BuildConfig.DEBUG)
            .setInitialLifecycleState(LifecycleState.RESUMED)
            .build();
    }

-keep class com.facebook.cache.disk.DiskStorageCache {
   private boolean maybeUpdateFileCacheSize();
}
