[Android] Building from bundle

[ngreenwood6]

I have been working with react-native on iOS and found the bundling option in the AppDelegate.m file and it works great once you bundle it. However, I saw that Android was released today and I am not able to figure out how to do the same on Android. In iOS there is some code like this:

sourceURL = [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];

Is there an equivalent way to do this in Android or am I missing something? I just want to bundle it on the device so I can use it without being near my computer.

I'm also interested in the location of the AppDelegate.m equivalent for Android. Thanks.

MainActivity.java is the equivalent of the AppDelegate.

@ngreenwood6 In MainActivity.java generated from template project there is a line setBundleAssetName("index.android.bundle") which basically makes java native code load js from android assets but with the current setup this will only happen if the file is present in assets.
Then you should be able to use react-native bundle to generate js bundle in the assets folder from which android build system should pick it up, but apparently this step doesn't seem to work cc @foghina

Ok. I was looking for how to download the index.android.bundle over http from the android device. I'll wait 0.12 then!

@sulliwane - oh, that works right now - see: https://facebook.github.io/react-native/docs/running-on-device-android.html#content

@brentvatne AWSOME, thanks a lot.

As a workaround you may have try the following:

1. Run packager in your project dir: react-native start
2. Use curl to fetch bundle from server and place it in android asset dir: curl -k 'http://localhost:8081/index.android.bundle' > android/app/src/main/assets/index.android.bundle

In addition to @kmagiera's workaround, you may also want to pass in the query params to the packager for minifying / disabling dev:
http://localhost:8081/index.android.bundle?dev=false&minify=true&runModule=true

For the params available, see: https://github.com/facebook/react-native/blob/master/packager/README.md#pathtomodulenamemapbundle-query-params

i got "index.android.bundle", and then what should i do to let it to be an apk file?

[stephenparish]

You can drop that into android/src/main/assets/.

Closing as this feature is already in the stable releases.
