Original Android version

I am starting out in hybrid development and I chose cordova and ionic to start. I am following ionic documentation. However, after creating a new ionic project and adding android as a platform, I fail repeatedly when trying to build an android platform. I've been trying to fix this issue for several days now. Please help so I can move forward with some real development.

Finally I was able to solve it by going to the folder C:\todo\platforms\android\ant-build

where todo

is the name of the ionic project I created and rename the file classes.dex.d

toclasses.dex

In general, I may have tried removing the platform and adding it again using the command line.

cordova platform rm android

cordova platform add android


But I'm glad you found a fix.

Glad you could figure it out! The easiest way I've found to create ionic androids and ios is via intel xdk. If you already have an ionic project, you can import it as an intel project, it has a built in device emulator and build server. Just hit build and it will automate the process. It also handles all config files for you and gives you a nice ui to edit them. https://software.intel.com/en-us/html5/tools

To fix the problem, make sure the Android SDK is installed successfully, If yes

1) Go back from the cordova project directory (cd ..) 2) Then go to the cordova project directory and use "cordova platform add android --save --fetch" to fetch 3) If no error occurs, try deleting the platform and again add

This works for me
