Test with xwalk AAR library

Pre-requisites¶ ↑

1. Install JDK that version need 6 or higher for Gradle. Then set JAVA_HOME environment to point to the install directory of the desired JDK.

   JAVA_HOME = /path/to/jdk

2. Use Gradle Wrapper to build our project, Gradle will be automatically downloaded and used.Copy following construct files in your project directory from my sample(powerbuilder.sh.intel.com/public/junwei/AARTest/XWalkEmbed.tar.gz).

   RootProject/
     gradlew
     gradlew.bat
     gradle/wrapper/
       gradle-wrapper.jar
       gradle-wrapper.properties
   

3. Install Maven (>version 3.1.1): maven.apache.org/download.cgi

4. Setting Wrapper to work behind Proxy

   • build it with proxy first time for download Gradle.

     ./gradlew –Dhttp.proxyHost=127.0.0.1  -Dhttp.proxyPort=8118 clean build

   • For Connection to repo1.maven.org, make directory in /home/user/.gradle/ as gradle.properties, then add follow codes.

     systemProp.http.proxyHost=127.0.0.1
     systemProp.http.proxyPort=8118
     systemProp.https.proxyHost=127.0.0.1
     systemProp.https.proxyPort=8118

   • set maven proxy,in config/settings.xml config file

     <settings>
       <proxies>
         <proxy>
           <protocol>http</protocol>
           <host>127.0.0.1</host>
           <port>8118</port>
         </proxy>
       </proxies>
     </settings>

Use Crosswalk as Android library project¶ ↑

1. Use AAR by local maven repository, Install it to projectRoot/libs directory. the Dversion is crosswalk version

   mvn install:install-file -DgroupId=com.xwalk -DartifactId=xwalk_core_library -Dversion=7.35.135.0 -DgeneratePom=true  -Dpackaging=aar  -Dfile=xwalk_core_library.aar -DlocalRepositoryPath=/path/to/projectRoot/libs

Create and Build your Android project with Crosswalk¶ ↑

1. Create Android Project, using the Crosswalk webview APIs.

2. The reference to maven repo in build.gradle will look like. if use local repo, the url is set to ‘libs’

   Repositories {
     Maven {
       url ‘https://download.01.org/crosswalk/releases/crosswalk/android/maven2’
     }
   }

3. The dependency (a reference) to the AAR library will look like(7.35.135.0 is crosswalk version):

   Dependencies {
      Compile ‘com.xwalk:xwalk_core_library:7.35.135.0’
   }

4. uncomment the line of “ext.multiarch=true” in libraries.gradle, which support multi architecture.

5. Build your project with Gradle, follow command will build the corresponding arch apk in build/apk directory

   ./gradlew assemblex86 
   ./gradlew assemblearmv7

also we can use “./gradlew build” to build all of version at once.

1. if report error about “failed to find build tools version 19.0.0”, please check it use “android” command.
