Build Process Integration
Add Penmanship to your buildscript depdencies and apply the plug-in:
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:0.7+'
classpath 'com.mindsnacks:penmanship:CURRENT-VERSION'
}
}
apply plugin: 'penmanship'
Then create a task to convert your Markdown files:
import com.mindsnacks.penmanship.gradle.ConvertMarkdownDirectoryToAndroidResourcesDirectoryTask
import com.android.build.gradle.tasks.ProcessAndroidResources
task generateMarkdownResources(type: ConvertMarkdownDirectoryToAndroidResourcesDirectoryTask) {
def inputTree = file('path/to/directory/containing_only_your_markdown/and_images')
inputs.dir inputTree
outputs.dir file("penmanship_gen/res")
}
tasks.withType(ProcessAndroidResources) { processResourcesTask ->
processResourcesTask.dependsOn generateMarkdownResources
}
Finally, just add your generated XML directory to your source set:
android {
sourceSets {
main {
res.srcDir 'penmanship_gen/res'
}
}
}
App Integration
Loading Layouts
Since there is not one super common way of using the generated XML, it's up to you to inflate the layouts and integrate them into your app. Markdroid provides a very small helper library to make this easy, just add it as an app dependency:
compile 'com.mindsnacks:penmanship-helper:CURRENT-VERSION@aar'
This library provides a few methods for easily loading layout files and enabling rich text. To see an example, check out MainActivity.java in the example project.
Styling Layouts
Each Markdown element gets its own layout in the generated layout XML files. It's up to you to implement these styles. For an example implementation, refer to the example project's styles file.
Markdown Support
Markdown support is still somewhat limited. The following features work:
- Text formatting (bold and italics)
- Headings
- Blockquotes
- Unordered and ordered lists
- Images (only local images, can't be inline with text)
- Links
