Method Detail

createAssetLoader

public static JSBundleLoader createAssetLoader(android.content.res.AssetManager assetManager,
                               java.lang.String assetFileName)

This loader is recommended one for release version of your app. In that case local JS executor should be used. JS bundle will be read from assets directory in native code to save on passing large strings from java to native memory.

createCachedBundleFromNetworkLoader

public static JSBundleLoader createCachedBundleFromNetworkLoader(java.lang.String sourceURL,
                                                 java.lang.String cachedFileLocation)

This loader is used when bundle gets reloaded from dev server. In that case loader expect JS bundle to be prefetched and stored in local file. We do that to avoid passing large strings between java and native code and avoid allocating memory in java to fit whole JS bundle in it. Providing correct of downloaded bundle is required for JS stacktraces to work correctly and allows for source maps to correctly symbolize those.

createRemoteDebuggerBundleLoader

public static JSBundleLoader createRemoteDebuggerBundleLoader(java.lang.String sourceURL)

This loader is used when proxy debugging is enabled. In that case there is no point in fetching the bundle from device as remote executor will have to do it anyway.

loadScript

public abstract void loadScript(ReactBridge bridge)
