Crosswalk - Build and Manifest

I'm using Crosswalk for projects that need to run on Android 2.2 and up.
I'm looking for any documentation about manifest.json because I didn't find anything that lists properties I can use.

I would like to know too if there is a way to manually edit AndroidManifest.xml before build in order to change permissions or SDK version.
Eventually, I would be glad if I could move the build folder from the Crosswalk-environment to my project folder. For the moment, I can only move APKs with --target-dir.
Here is my folder structure :

 -MyApp_project  
     -MyApp_www
     -[Move build folder here]
 -Crosswalk-env
     -...content...
     -[build folders are there]

Thanks

Solution

I'm new to crosswalk, so my answer should not be perfect.

As my previous comment, the documentation of manifest.json is found in https://github.com/crosswalk-project/crosswalk-website/wiki/Crosswalk-manifest.

It says you can set permissions properties so you don't have to edit AndroidManifest.xml directly. (though I have not tested it)

I don't know how to handle crosswalk's SDK directory neither, but simple build.bat script like this mitigate my pain.

@set XWALK_HOME=c:/path/to/crosswalk-5.34.104.5
@set ARCH=x86
@set OUT=%~dp0%out

@mkdir %OUT%

@cd %XWALK_HOME%
python make_apk.py ^
 --manifest=%~dp0/src/manifest.json ^
 --package=this.is.required.for.shared.mode ^
 --target-dir=%OUT% ^
 --mode=shared ^
 --enable-remote-debug
@cd %~dp0
