Cordova
Install
Install nodejs and npm
sudo apt-get install nodejs npm
Install cordova
sudo npm install -g cordova
cordova need node and ubuntu install nodejs
sudo ln -s /usr/bin/nodejs /usr/local/bin/node
install cordova-browser from git to have linux support
sudo npm install -g git://git.apache.org/cordova-browser.git
Update
sudo npm update -g
Install Android SDK
Create /etc/etc/profile.d/android.sh or add in .bash_profile
export ANDROID_HOME=/lab/android-sdk-linux/ export PATH=$PATH:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools
Project
Create project
cordova create /lab/peper-memory org.csgalileo.peper.memory PeperMemory
Add android support
cd /lab/peper-memory cordova platform list cordova platforms add android cordova platforms add browser # temporary patch # cp /usr/local/lib/node_modules/cordova-browser/bin/templates/project/cordova/run ./platforms/browser/cordova/run
Add to platforms/browser/cordova/run
case 'linux': spawn('chromium-browser', ['--test-type', '--disable-web-security', '--user-data-dir=/tmp/temp_chrome_user_data_dir_for_cordova_browser', project]); break;
Crosswalk
Optionally it is possible to use crosswalk instead of android webview
Add android platform to project
cordova platforms add android
Download [https://crosswalk-project.org/documentation/downloads.html|crosswalk]
CROSSWALK=/lab/crosswalk/crosswalk-cordova-10.39.235.15-arm rm -fR platforms/android/CordovaLib/* cp -a ${CROSSWALK}/framework/* platforms/android/CordovaLib/ cp -a ${CROSSWALK}/VERSION platforms/android/
Add to platforms/android/AndroidManifest.xml
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
Build both the CordovaLib and xwalk_core_library
cd platforms/android/CordovaLib/ android update project --subprojects --path . --target "android-19" ant clean debug cd .. # platforms/android/ rm -Rf ant-gen rm -Rf ant-build cd ../.. cordova build android

Video autoplay
Con ionic-crosswalk i video partono da soli con il set di src via javascript
if (! $('#video1')[0].src) { $('#video1')[0].src = "http://..."; } $("#video1")[0].currentTime = 0; // rewind $("#video1")[0].play();
Cordova
CordovaApp.java
super.init(); super.appView.getSettings().setMediaPlaybackRequiresUserGesture(false);
Cordova Crosswalk
...
super.init();
getSettings(super.appView).setMediaPlaybackRequiresUserGesture(false);
...
/* rende plubblica la API mascherata dalle nuove release di crosswalk */
private XWalkSettings getSettings(XWalkView webView)
{
try
{
Method ___getBridge = XWalkView.class.getDeclaredMethod("getBridge");
___getBridge.setAccessible(true);
XWalkViewBridge xWalkViewBridge = null;
xWalkViewBridge = (XWalkViewBridge)___getBridge.invoke(webView);
XWalkSettings xWalkSettings = xWalkViewBridge.getSettings();
return xWalkSettings;
}
catch (Exception e)
{
e.printStackTrace();
}
return null;
}
Posizionare un set di src dopo il device ready
$('#video1')[0].src = "http://192.168.2.125:8000/lib/exe/fetch.php?media=contrade:pergari:pergari_int.webm";
