The blockly-android project is no longer actively developed by the Google Blockly team. We will continue to review and accept pull requests. If you are looking to create a new Blockly-based app, we recommend using the web version in a WebView. We have also create an Android Studio demonstration project that does exactly this.
Blockly is a library for building drag-and-drop visual editors for JavaScript and other programming languages. Blockly for Android is a developer preview of Blockly's editor built with standard Android views and fragments, offering more responsive touch performance and easier integration in Android apps.

Blockly has an active developer forum. Please drop by and say hello. Show us your prototypes early; collectively we have a lot of experience and can offer hints which will save you time.
