[ERROR] Cordova encountered an error.
        You may get more insight by running the Cordova command above directly.

[ERROR] An error occurred while running cordova run android (exit code 1).

I did not recieve this error before running Ionic.

Answer 1

The 01.org server seems to be down. So till the servers are back online, you can ask Gradle to use the local copy of Crosswalk.

I was having the same issue from last one hour. The following solution worked for me.

Open platforms\android\cordova-plugin-crosswalk-webview\*-xwalk.gradle file in your project directory, where * is your project name.

Look for the section -

dependencies {
    compile xwalkSpec
}

Replace it with your exact Crosswalk version which you find in Chrome Developer Tools by typing window.navigator.userAgent in your Developer Tools console.

So your final data would look something like this -

dependencies {
    compile 'org.xwalk:xwalk_core_library:23.53.589.4'
}

Answer 2

1 Get crosswalk version

There are another two ways to get xwalk_core_library version, you can use either of them:

• Go to platforms/android/build/intermediates/exploded-aar/org.xwalk‌​/xwalk_core_library/‌​, then you can see version like 19.49.514.5

• In the Google cache, you can select a version number

2 Change the gradle

Just like @hemantv said, in file platforms\android\cordova-plugin-crosswalk-webview*-xwalk.gradle

Change the file form

dependencies {
    compile xwalkSpec
}

to

dependencies {
    compile 'org.xwalk:xwalk_core_library:19.49.514.5'
}

19.49.514.5 is the version get from the step one.

Another way, you can use this plugin temporarily:

cordova plugin add https://github.com/zhouzhongyuan/cordova-plugin-crosswalk-webview

It just fixed this error.
