Cordova and Bower/Polymer Error

Question

I can't run and build my Cordova app while Polymer is installed via Bower.

At first I created my project via Cordova, and added Android as a platform.

I then initialized bower in my "www" directory in my app, and tried to run the app. There were no errors.

But when I add Polymer/polymer + Polymer/core-elements and Polymer/paper-elements as components via Bower, I'm getting this error:

Can anyone help me? This error only shows when Polymer is installed.

Answer 1

You need to go to ${ANDROID_HOME}/tools/ant/build.xml and override the following parameter:

<property name="aapt.ignore.assets" value="" />

With new values, ignoring .*.

But instead of playing around with the build files, I would suggest that you create a new cordova project, copy your code to www and remove all .bower.json and .gitignore files. Here are the commands to do so:

find . -type f -name ".*" -exec rm {} \\;

You also need to unzip any already zipped file and need to run:

find . -type f -name "*.gz" -exec gunzip {} \\;

Or better yet, use hard links. This way you would not have to copy the files again.
