Markwon is a markdown library for Android. It parses markdown following commonmark-spec with the help of amazing commonmark-java library and renders result as Android-native Spannables. No HTML is involved as an intermediate step. No WebView is required. It's extremely fast, feature-rich and extensible.
It gives ability to display markdown in all TextView widgets (TextView, Button, Switch, CheckBox, etc), Toasts and all other places that accept Spanned content. Library provides reasonable defaults to display style of a markdown content but also gives all the means to tweak the appearance if desired. All markdown features listed in commonmark-spec are supported (including support for inlined/block HTML code, markdown tables, images and syntax highlight).
Markwon comes with a sample application. It is a
collection of library usages that comes with search and source code for
each code sample.
Since version 4.2.0 Markwon comes with an editor to highlight markdown input as user types (for example in EditText).

Based on this cheatsheet
Emphasis, aka italics, with asterisks or underscores.
Strong emphasis, aka bold, with asterisks or underscores.
Combined emphasis with asterisks and underscores.
Strikethrough uses two tildes. Scratch this.
- First ordered list item
- Another item
- Unordered sub-list.
-
Actual numbers don't matter, just that it's a number
-
Ordered sub-list
-
And another item.
You can have properly indented paragraphs within list items. Notice the blank line above, and the leading spaces (at least one, but we'll use three here to also align the raw Markdown).
To have a line break without a paragraph, you will need to use two trailing spaces. Note that this line is separate, but within the same paragraph. (This is contrary to the typical GFM line break behaviour, where trailing spaces are not required.)
- Unordered list can use asterisks
- Or minuses
- Or pluses
I'm a relative reference to a repository file
You can use numbers for reference-style link definitions
Or leave it empty and use the link text itself.
Inline code has back-ticks around it.

But let's throw in a <b>tag</b>.
Colons can be used to align columns.
| Tables | Are | Cool |
|---|---|---|
| col 3 is | right-aligned | $1600 |
| col 2 is | centered | $12 |
| zebra stripes | are neat | $1 |
There must be at least 3 dashes separating each header cell. The outer pipes (|) are optional, and you don't need to make the raw Markdown line up prettily. You can also use inline Markdown.
| Markdown | Less | Pretty |
|---|---|---|
| Still | renders |
nicely |
| 1 | 2 | 3 |
Blockquotes are very handy in email to emulate reply text. This line is part of the same quote.
Quote break.
This is a very long line that will still be quoted properly when it wraps. Oh boy let's keep writing to make sure this is long enough to actually wrap for everyone. Oh, you can put Markdown into a blockquote.
Nested quotes
Hello!
And to you!
