They have the same set of features, same class names and similar ways of testing the functionality.

+Text Styling
+============
+This sample shows how to style text on Android using spans, in Java.
+
+Introduction
+------------
+## Features
+Parse some hardcoded text and do the following:
+* Paragraphs starting with “> ” are transformed into quotes.
+* Text enclosed in “```” will be transformed into inline code block.
+* Lines starting with “+ ” or “* ” will be transformed into bullet points.
+To update the text, modify the value of `R.string.display_text`.
+This project is not meant to fully cover the markdown capabilities and has several limitations; for example, quotes do not support nesting other elements.
+
+## Implementation
+The text is parsed in the [`Parser.parse`](https://github.com/googlesamples/android-text/blob/master/TextStyling-Java/app/src/main/java/com/android/example/text/styling/parser/Parser.java#L62) method and the spans are created in the [`MarkdownBuilder.markdownToSpans`](https://github.com/googlesamples/android-text/blob/master/TextStyling-Java/app/src/main/java/com/android/example/text/styling/renderer/MarkdownBuilder.java#L62) method.
+To see how to apply a span, check out [`MarkdownBuilder.buildCodeBlockSpan`](https://github.com/googlesamples/android-text/blob/master/TextStyling-Java/app/src/main/java/com/android/example/text/styling/renderer/MarkdownBuilder.java#L120). To see how to apply multiple spans on the same string, see [`MarkdownBuilder.buildQuoteSpan”](https://github.com/googlesamples/android-text/blob/master/TextStyling-Java/app/src/main/java/com/android/example/text/styling/renderer/MarkdownBuilder.java#L108). For examples of creating custom spans, see [`BulletPointSpan`](https://github.com/googlesamples/android-text/blob/master/TextStyling-Java/app/src/main/java/com/android/example/text/styling/renderer/spans/BulletPointSpan.java), [`CodeBlockSpan`](https://github.com/googlesamples/android-text/blob/master/TextStyling-Java/app/src/main/java/com/android/example/text/styling/renderer/spans/CodeBlockSpan.java) or [`FontSpan`](https://github.com/googlesamples/android-text/blob/master/TextStyling-Java/app/src/main/java/com/android/example/text/styling/renderer/spans/FontSpan.java).
+
+## Testing
+Text parsing is tested with JUnit tests in [`ParserTest`](https://github.com/googlesamples/android-text/blob/master/TextStyling-Java/app/src/test/java/com/android/example/text/styling/parser/ParserTest.java). Span building is tested via Android JUnit tests, in [`MarkdownBuilderTest`](https://github.com/googlesamples/android-text/blob/master/TextStyling-Java/app/src/androidTest/java/com/android/example/text/styling/renderer/MarkdownBuilderTest.java).
