Hi everyone,
If someone is still interested, I have just developed a new Android Keyboard extension for Stencyl. This extension has the exact same blocks as the built in keyboard support. Since this is a normal extension, you will find the blocks in the "Extension" tab of the blocks palette. This extension supports the built in keyboard events (add event > mobile > keyboard).
Since there are a lot of different Android devices, I need some help with testing. I would be interested in hearing your feedback about this extension.
Notes:
1) This is an Android extension only! If everything works as expected, the Stencyl team will merge this extension with the built in iOS keyboard support.
2) This is a work in progress that won't be supported by the Stencyl team until it becomes part of the engine.
EDIT: You can find the extension a few posts below.
