[Android] [Fixed] fix indexed RAM bundle

Co-Authored: @zamotany

Summary

With React Native 0.59.8 the app keeps crashing with indexed RAM bundle on Android with the following error:

2019-05-09 11:58:06.684 2793-2856/? E/AndroidRuntime: FATAL EXCEPTION: mqt_js

After investigation we found that when using any bundle, let it be non-ram, FIle RAM bundle or Index RAM bundle, the CatalystInstanceImpl.java is always using loadScriptsFromAsset, which is calling CatalystInstanceImpl::jniLoadScriptFromAssets in C++. This method when checking if bundle is a RAM bundle, uses JniJSModulesUnbundle::isUnbundle which only check for js-modules/UNBUNDLE - file generated when building File RAM bundle. There is no other logic to handle Indexed RAM bundle, so it figures that the bundle is not RAM, cause there is no js-modules/UNBUNDLE file and tries to load as regular bundle and fails.

In this PR we added check if it is indexed RAM bundle in jniLoadScriptFromAssets and handle it if it is.

Changelog

[Android] [Fixed] fix indexed RAM bundle

Solves #21282

Test Plan

Add this setup to app/build.gradle file

project.ext.react = [
    bundleCommand: "ram-bundle",
    extraPackagerArgs: ["--indexed-ram-bundle"],
]

and run application in release mode.

Note

Please include it in the next 0.59 patch release

The integration CI failure is a network problem that only occurred during package fetching in the node10 container. It would be nice to add a building and loading of indexed RAM bundle into the e2e suite, but otherwise this looks good.

@hramos were you waiting to get the CI in shape before merging this?

I rebased this branch on master because we can't merge into the stable branch, it needs to land on master first.

Here are the build errors I'm getting at FB:

Hey @cpojer i fixed compilation issues you mentioned. However there is a different issue on master branch with indexedRAMbundle app crashes with error -

I spend a moment on debugging and i think it is related to TurboModules since it crashes here

https:/facebook/react-native/blob/master/Libraries/TurboModule/TurboModuleRegistry.js#L35

when tries to load module with name SourceCode, so the JS bundle is loaded properly.

It still works perfectly on 59.8
