Helper script to convert an Ionic/Cordova app to a Crosswalk app

cordova-to-crosswalk.md

Convert a Cordova/Ionic project to a Crosswalk project

Converts an existing Cordova/Ionic project to a Crosswalk project. When the script is done running, you should have a fat 40MB APK file in platforms/android/ant-build.

This assumes you have the following already installed: cordova, ant, android, and that your ANDROID_HOME is set to point to the Android SDK.

This will work on both x86 and ARM. If you want to build two separate APKs so that they're smaller, then modify the script; the script at least shows how it works.

Step 1: download the "Cordova Android" libraries from the Crosswalk downloads page. You don't need anything except for the "Cordova Android" ones.

Step 2 Unzip them both.

Step 3 Navigate to your project directory and run:

./prepare_crosswalk \
  /path/to/crosswalk-cordova-VERSION-x86 \
  /path/to/crosswalk-cordova-VERSION-arm

Then run either:

ionic build android # for ionic

or

cordova build android # for cordova

Thanks to this article for figuring out how to get this to work.

prepare_crosswalk.sh

#!/usr/bin/env bash
#
# usage: provide a path to a crosswalk-cordova-x86 and crosswalk-cordova-arm library,
# run in the current (project) directory, and it will set up crosswalk for you
#
# ./prepare_crosswalk.sh /path/to/crosswalk-cordova-VERSION-x86 /path/to/crosswalk-cordova-VERSION-arm
# 

X86=$1
ARM=$2

if [[ -z $X86 ]]; then
  echo 'usage: ./prepare_crosswalk /path/to/crosswalk-cordova-VERSION-x86 /path/to/crosswalk-cordova-VERSION-arm'
  exit 1
fi
  
if [[ -z $ARM ]]; then
  echo 'usage: ./prepare_crosswalk /path/to/crosswalk-cordova-VERSION-x86 /path/to/crosswalk-cordova-VERSION-arm'
  exit 1
fi

cordova platform rm android
cordova platform add android@3.5.1
rm -fr platforms/android/CordovaLib/*
cp -a $X86/framework/* platforms/android/CordovaLib/
cp -a $ARM/framework/xwalk_core_library/libs/armeabi-v7a platforms/android/CordovaLib/xwalk_core_library/libs/
cp $X86/VERSION platforms/android/
cd platforms/android/CordovaLib/
android update project --subprojects --path . --target "android-19"
ant debug
cd -

# sed sucks on a mac, can't do sed -i
cat platforms/android/AndroidManifest.xml | sed 's/<\/manifest>/    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" \/>;    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" \/>;<\/manifest>/' > platforms/android/AndroidManifestNew.xml
# sed doesn't play nice with newlines either, so...
tr ';', '\n' < platforms/android/AndroidManifestNew.xml > platforms/android/AndroidManifest.xml
rm -f platforms/android/AndroidManifestNew.xml

@nolanlawson Thank you for this! It is the only thing that worked for me. I would add that the relevant Cordova version is 3.6.
