cordova crosswalk project migration — error

Question

I am trying to migrate my cordova project to crosswalk.

I am using [following download] ( https://download.01.org/crosswalk/releases/crosswalk/android/stable/10.39.235.15/arm/crosswalk-cordova-10.39.235.15-arm.zip ) of crosswalk.

My system is having android 4.4 & 4.3 CLI SDK installed. I want to compile my android app for Android 4.3 (API 18).

"cordova -v" command run output :

4.2.0

"cordova platform version android" command run output :

Installed platforms: android 3.6.4
Available platforms: amazon-fireos, blackberry10, browser, firefoxos, windows, windows8, wp8

I am following following link to Migrate cordova project to crosswalk.

VERSION file contains string :

3.6.3

I am getting following error in "ant dbg" stage. Please suggest how to resolve it ?

"ant dbg" command run output :

debug:

-code-gen:

I've only been using crosswalk 9+cordova 3.5, but I think you should try to use cordova android 3.6.3 instead of 3.6.4 :

cordova platform remove android
cordova platform add android@3.6.3

And then you can follow again the migration guide and replace the cordova-lib with crosswalk-cordova.

And make sure to specify --target "android-19" when building xwalk_core_library.

Ok, I've made a little search about the error message you have.

The error says method setFixedLengthStreamingMode(long contentLength) is not found in HttpsURLConnectionImpl.java.

It seems setFixedLengthStreamingMode is new from java 7, so my guess is you are using an older version of java.

To be sure, run java -version in a terminal.If the output displays Java version 1.6.x, then your problem should be solved after upgrading to java 7 or 8.
