Fix all showstopper bugs in Slate on Android (Help us by reporting and testing bugs)

The purpose of this issue is to consolidate and fix all Android bugs, especially those that are showstoppers (i.e. bugs that if we don’t fix we can’t claim to have Android support).

If you want Android support, you can help make it happen by testing and providing good bug reports. Note: If you can’t recreate the bug, please do not submit it (e.g. needs to e more specific than “sometimes backspace doesn’t work”).

Thank you to the many that have asked what they can do to help with Android. This is the best way to do it. Once I’m off on the next project, it may be a while before I get back here.

Supported Android Versions 8 and 9 (API 26, 27, 28)

Currently supporting Android 8 and Android 9. Working on supporting Android 7 right now. Will post here when you can start testing Android 7.

Where to test Android support

Use my Slate examples site (not the official Slate examples). The official repo does not have my latest Android updates:

Thanks for all the submissions guys. I’m working on a new approach so please hold off on bug reports for now. For more information, please see this comment in the IME issue https://github.com/ianstormtaylor/slate/issues/2062#issuecomment-492320466

Bug: Typing any text throws an exception

Severity

Major

Rationale for severity

This is considered major because typing any text will not update the editor state - this means that any edit on the text will not do anything. Although the UI appears to be working as intended, the editor state is not properly updated so you cannot persist/save the new state.

Description

Open the editor, tap on the editor to begin typing, then type any character. This will throw the following exception:

Uncaught TypeError: Cannot read property 'values' of undefined

This exception is thrown during the reconcile function in the Android plugin. This function calls setTextFromDomNode -> node.getLeaves -> compile. The compile function throws an error because annotation and decorations values are undefined.

You’ll see in the video that the Slate’s value as text doesn’t get updated

Additional Comments (if any)

I had to pull the latest project becase the currently deployed examples on https://thesunny.github.io/slate/#/composition/split-join does not have the latest version of slate and slate-react.
